  Citation × Citation Citation Abstract Copy Title: Work Completed for Compliance with the Biological Opinion for Hatchery Programs in the Willamette Basin USACE funding: 2004 Annual Report Abstract -- The National Marine Fisheries Service (NMFS) has listed spring chinook salmon(Oncorhynchus tshawytscha) and winter steelhead (O. mykiss) in the Upper Willamette River Evolutionarily Significant Unit (ESU) as threatened under the Endangered Species Act (ESA; 64 FRN 14308; 64 FRN 14517). Concomitant with this listing, any actions taken or funded by a federal agency must be evaluated to assess whether these actions are likely to jeopardize the continued existence of threatened and endangered species, or result in the destruction or impairment of critical habitat. Several fish hatcheries operate within the ESU and may impact wild populations of listed species. Although all of the artificial propagation programs that potentially affect listed salmonids in the Upper Willamette River ESUs are operated by the Oregon Department of Fish and Wildlife(ODFW), 90% of the funding for these operations comes from the U.S. Army Corps of Engineers (COE). Possible risks of artificial propagation programs have been well documented. Hazards include disease transfer, competition for food and spawning sites, increased predation,increased incidental mortality from harvest, loss of genetic variability, genetic drift, and domestication (Steward and Bjornn 1990; Hard et al. 1992; Cuenco et al. 1993; Busack and Currens 1995; NRC 1996; and Waples 1999). Hatcheries can also play a positive role for wild salmonids by bolstering populations, especially those on the verge of extirpation, providing a genetic reserve in the case of extirpation, and providing opportunities for nutrient enrichment of streams (Steward and Bjornn 1990; Cuenco et al. 1993). The objective of this project is to evaluate the potential effects of hatchery programs on naturally spawning populations of spring chinook and winter steelhead within the Upper Willamette River ESU. The project employs four types of activities to achieve this goal: sampling of returns to hatcheries, creels to assess fisheries, monitoring of adult and juvenile migration through the use of traps and video observations, and monitoring natural production through spawning ground surveys.

For more detailed information, the reader should refer to the Draft Feasibility Report/Environmental Impact Statement and attached appendices. The genesis of this study is the National Marine Fisheries Service's 1995 Biological Opinion for the Reinitiation of Consultation on 1994-1998 Operation of the Federal Columbia River Power System and Juvenile Transportation Program in 1995 and Future Years (95 Biological Opinion). While the focus of this study is the relationship between the four dams on the lower Snake River and their effects on juvenile fish traveling toward the ocean, the implications of the study are broader. The Draft Feasibility Report/Environmental Impact Statement includes the best available information on the biological effectiveness, engineering, economic effects, and other environmental effects associated with the four specific alternatives. It does not, however, include a recommendation or identify a preferred alternative. This will give the public and other agencies an opportunity to review and understand this information and provide input before a preferred alternative is selected. At the same time, this will allow the region to consider the Habitat, Hatcheries, Harvest, and Hydropower Working Paper on salmon recovery by the Federal Caucus. Information from this process will be fully examined to determine how it may influence decisions on actions for the lower Snake River.

  	Citation × Citation Citation Abstract Copy Title: Seeking refuge: making space for migratory waterfowl and wetlands along the Pacific Flyway Author: Wilson, Robert Michael Year: 2003, 2005, 2004 Abstract "Seeking Refuge" examines the history of migratory waterfowl management along the Pacific Flyway, the westernmost of four main migration routes in North America. Drawing on approaches from historical geography and environmental history, this study shows how wildlife officials developed migratory bird refuges in Oregon and California, where over 60 percent of Pacific Flyway waterfowl winter. During the early-twentieth century, reclamation and river diking eliminated most of the wetlands in the birds' wintering range. Bird enthusiasts such as bird watchers and duck hunters successfully lobbied for the creation of wildlife refuges in a few areas along the flyway. These early refuges failed to protect waterfowl habitat and they were severely degraded by reclamation. In the 1930s and 1940s, the U.S. Fish and Wildlife Service (FWS) and its predecessor, the Bureau of Biological Survey, undertook an ambitious program to resurrect these sanctuaries and to create new ones. Many farmers opposed these refuges out of fear that waterfowl would damage crops. To respond to these concerns and to ensure an adequate food supply for the birds, the FWS raised rice, barley, and other grains. The agency adopted many of the technologies of modern, industrial agriculture including synthetic herbicides and insecticides such as 2, 4-D and DDT. By the 1960s, the refuges had become largely mirrors of the surrounding irrigated farmlands, the main difference being that the FWS raised grain for waterfowl rather than for market. Refuges could not escape the agricultural settings in which they were embedded. As units within the irrigated countryside, Pacific Flyway refuges were often at the mercy of nearby farmers and federal reclamation agencies. Poor water quality and insufficient supplies of water often hampered FWS efforts to manage refuges. In the late-twentieth century, reduced water supply due to diversions to California municipalities and to sustain endangered fish species affected the amount of water reaching refuges. This dissertation has other goals. First, it critiques the anthropocentrism of most historical geography by focusing on how political, cultural, and ecological factors affected wildlife. Second, it contributes to the literature on the state's role in environmental protection by investigating the overlapping, and often contradictory, spaces within which wildlife managers implemented environmental regulations.

Klamath Basin Ecosystem Restoration Office. Year: 2000, 2005, 2004 Programmatic Environmental Assessment Summary This Environmental Assessment (EA) provides compliance with the National Environmental Policy Act (NEPA) for restoration actions undertaken by the US Fish & Wildlife Service's Klamath Basin Ecosystem Restoration Office (ERO) in Klamath Falls, Oregon. These restoration activities are needed due to the large-scale loss of wetland and riparian habitat and degraded water quality. The purpose of these restoration efforts is the improvement of conditions of the watershed with specific regard to habitat and water quality, resulting in, among other benefits, improved conditions for the endangered fish species (bull trout and Lost River and shortnose sucker) populations of the basin. The geographic scope of this EA is defined as the upper Klamath River basin, including the entire watershed from Irongate Dam upstream to the headwaters. This EA is intended to provide NEPA compliance for restoration projects conducted between the years 2000 and 2010. The ERO was established in 1993 to sponsor and assist with a variety of restoration activities in the Klamath Basin. The ERO funds and provides technical assistance to restoration projects involving private landholders, concerned groups, and other state, federal, and tribal agencies. Four alternatives are presented in this EA. The proposed alternative (Alternative 1) consists of a comprehensive program of ecosystem restoration, promoting projects in both riparian areas and in upland habitats. This would continue the current program in effect since 1994. NEPA compliance would primarily be carried out via a single, programmatic document saving time and funds. The Fish & Wildlife Service proposes to fund and administer the following projects types: Riparian Projects: (fencing for livestock management; native plant establishment & diversification; non-native plant removal/control; erosion control; contour re-establishment; impoundment removal; wildlife habitat improvements) Wetland Projects: (fencing; wetland restoration and enhancement; wildlife habitat improvements) Upland or Road Projects: (road abandonment, decommissioning, & obliteration; road drainage improvements and storm proofing, re-establishment of historic contours; silvicultural treatments; native plant establishment/diversification; non-native plant removal/control; fencing; landslide treatments; culvert/stream crossing upgrades; erosion control; wildlife habitat improvements). In-stream Projects: (habitat complexity and diversity improvements; hydrologic regime improvements; coarse woody debris supplementation; natural or artificial barrier removal, modification &/or creation; fish screens installation). Alternative 2 would concentrate restoration efforts only on riparian, instream, and wetland areas. Road projects would be conducted only within the riparian corridor, as defined. NEPA compliance would also be conducted programmatically. Alternative 3 would cease all restoration activities conducted and funded by the ERO in the Klamath Basin. This alternative would serve as a benchmark against which the effects of the restoration alternatives discussed above can be compared. Alternative 4, the "No Action" alternative, would continue current management policies with regard to NEPA compliance, providing compliance on a project by project basis requiring independent analysis for each project. The affected environment of the region is described in detail. The environment has been changed significantly since the 1890's due to logging, agriculture and urban development. An extensive system of dams, canals, and drainage structures has resulted in the conversion of approximately 80% of pre-settlement wetlands to agricultural uses. Riparian corridors have been similarly impacted, and upland forests regions have been affected by logging, road construction and other factors. These changes have contributed to problems with the water quality in the region, contributing to the listing of several fish species as threatened or endangered; loss of habitat has affected a large number of other species as well. The environmental effects of each alternative is analyzed. Some short term negative impacts could occur as a result of the projects authorized by both Alternative 1 and Alternative 2, but these would be strongly offset by the expected beneficial results to water quality and habitat conditions. Alternative 1 would be expected to have a greater overall effect on the environment than Alternative 2, since many of the underlying factors with which restoration efforts are concerned originate in upland conditions (i.e. sedimentation and hydrologic functionality). Alternative 3 would result in conditions remaining much as they are currently, although other programs and organizations are making efforts at restoration activities. The environmental impacts of individual projects anticipated under Alternative 4 would be generally the same as for similar projects under Alternative 1. The primary difference between the two alternatives would be the higher efficiency and improved cumulative analysis resulting from a programmatic approach as proposed in Alternative 1. Public participation in the NEPA process has been, and will continue to be, solicited and welcomed. Compliance with state and federal laws and regulations such as the Clean Water Act, National Historic Preservation Act, and the Endangered Species Act, as well as guidelines for contaminant surveys, will be carried out as detailed. While these projects are expected to play an important role in the restoration of the region, none of these alternatives are expected to have a significant impact when compared with the loss of wetland, riparian and upland habitats over the past century, impacts which do occur would be of a cumulatively beneficial nature. Other restoration efforts are being carried out in the area by other governmental and private groups, and it is expected that these combined efforts will achieve important beneficial results for the ecosystem.

In 1996, the 104th Congress of the United States chartered the Upper Klamath Basin Working Group (Public Law 104-333 - the Oregon Resources Conservation Act) to develop a plan for the Upper Basin that focuses on enhancing ecosystem restoration, improving economic stability, and minimizing impacts associated with drought on all resources and stakeholders. The Working Group is comprised of over 30 individuals appointed by the Governor of Oregon, representing federal, state, and local governments and agencies; the Klamath Tribes; conservation organizations; farmers and ranchers; and industry and local businesses. The objective of the Working Group is to develop and oversee a restorative course of action that allows for mutually beneficial gains for stakeholders wherein everybody in the Upper Basin can achieve positive, affirming results together, and where no one is left economically, culturally, or spiritually disadvantaged. Chapter 1 of this report presents a brief summary of the history of the Working Group and the conditions leading to the development of this effort. Chapter 2 describes the facilitated "interim planning process" the Working Group engaged in between April 2001 and July 2002. Chapter 3 presents the results of the interim planning process including key recommendations regarding Working Group decision-making and operating rules, technical data needs, future cost and time frame of the restoration planning process, and similar planning decisions. Chapter 4 describes the next steps and actions the Working Group is prepared to take to lead the restoration planning process. The Working Group's goals and objectives will be achieved through the Working Group's continued commitment to public outreach, collaborative problem solving, and implementation of real world solutions. Desired outcomes from implementation of the restoration plan include, but are not limited to, the following: improved water quality through the implementation of accepted Best Management Practices; restoration of wetlands and riparian habitat; enhancement of natural and structural water storage; improvements to irrigation efficiency and water conservation; economic growth and diversity through activities such as value added natural resource products and ecotourism; and enhancement of wildlife Tribal Trust resources.

Year: 2001, 2005, 2004 SIGNIFICANT FINDINGS The distribution of SOD2q values (measured sediment oxygen demand values corrected to 20°C [degrees Celsius]) had a median value of 1.6 g/m2/day (grams per square meter per day) in the spring and 1.7 g/m2/day in the late summer. These values were well within the range of values in the literature for sites with similar sediment characteristics: primarily silty with at least a moderate amount of organic content. Over most of the lake there appears to be relatively little variation in SOD 14the interquartile range in values was 0.4 g/m2/day in the spring and 0.7 g/m2/day in the late summer. A significant exception was apparent in Ball Bay, where SOD in the late summer was greater than 10.2 g/m2/day. In the absence of primary production, an SOD of this magnitude could deplete the water column of oxygen in a few days. This measurement provided evidence that localized areas of very high SOD occur episodically in the bays, perhaps associated with large algal mats being trapped by the lake circulation patterns. A statistical test for a spring to late summer difference in the median values of SOD confirmed that SOD in the late summer (median value 1.7 g/m2/day) was significantly higher than in the spring (median value 1.2 g/m2/day). The difference was primarily due to seasonal changes in temperature; when SOD values were corrected to 20°C, there was no seasonal difference in the median values. There was no correlation between SOD20 and the sediment characteristics measured in this study: percent fines, organic carbon, and residue lost on ignition.

A statistical test for a spring to late summer difference in the median values of SOD confirmed that SOD in the late summer (median value 1.7 g/m2/day) was significantly higher than in the spring (median value 1.2 g/m2/day). The difference was primarily due to seasonal changes in temperature; when SOD values were corrected to 20°C, there was no seasonal difference in the median values. There was no correlation between SOD20 and the sediment characteristics measured in this study: percent fines, organic carbon, and residue lost on ignition. Close

QREEON THE OREGON PLAN FOR SALMON AND WATERSHEDS The purpose of the Oregon Plan for Salmon and Watersheds ( the " Oregon Plan") as stated in the Plan and reaffirmed in this Executive Order is to restore Oregon's wild salmon and trout populations and fisheries to sustainable and productive levels that will provide substantial environmental, cultural, and economic benefits and to improve water quality. The Oregon Plan is a long- term, ongoing effort that began as a focused set of actions by state, local, tribal and private organizations and individuals in October of 1995. The Oregon Plan first addressed coho salmon on the Oregon Coast, was then broadened to include steelhead trout on the coast and in the Lower Columbia River, and is now expanding to all at- risk wild salmonids throughout the state. The Oregon Plan addresses all factors for decline of these species, including watershed conditions arid fisheries, to the extent those factors can be affected by the state. The Oregon Plan was endorsed and funded by the Oregon Legislature in 1997 through Oregon Senate Bill 924 ( 1 997 Or. Laws, ch. 7) and House Bill 3700 ( 1 997 Or. Laws, ch.' 8). The Oregon Plan is described in two principal documents: " The Oregon Plan," dated March 1997, and " The Oregon Plan for Salmon and Watersheds, Supplement I - steelhbad," dated January 1998. As used in this Executive Order, + the Oregon Plan also incorporates the Healthy Streams Partnership ( Oregon Senate Bill 101 0, 1 993- Or. Laws, ch. 263). The Oregon Plan is a cooperative effort of state, local, federal, tribal and private organizations and individuals. Although the Oregon Plan contains a strong foundation of protective regulations -- continuing existing regulatory programs and speeding the implementation of others - an essential principle of the Plan is the need to move beyond prohibitions and to encourage efforts to improve conditions for salmon through non- regulatory means. Many of the most significant contributions to the Oregon Plan are private and quasi- governmental efforts to protect and . restore salmon on working landscapes, including efforts by watershed councils. Salmon and trout restoration requires action and sacrifice across the entire economic and geographic spectrum of Oregon. The commercial and sport fishing industries in Oregon have been heavily affected by complete or partial closures of fisheries. The forest industry operates under the Oregon Forest Practices Act, and has contributed substantially to salmon recovery through habitat restoration projects on private lands and by funding a large pan of the state recovery efforts. The agriculture and mining industries are also taking actions that will protect and restore salmon and trout habitat and improve water quality ( including financial support of restoration efforts by the mining industry). Urban areas are developing water conservation programs, spending funds for wastewater treatment improvements to reduce point source pollution, reducing non- point source pollution and reducing activities that degrade riparian areas. All citizens of Oregon share responsibility for declining populations of wild salmon and trout, and it is important that there be both a broad commitment to reversing these historic trends and a sense that the burdens of restoration are being shared by all of society. It is also important that there be independent scientific oversight of the Oregon Plan. This oversight is being provided by the Independent Mutidisciplinary Science Team ( IMST), established under Oregon Senate Bill 924 ( 1 997 Or. Laws, ch. 7). ~ d'ditional legislative oversight for the Oregon Plan is being provided by the Joint Legislative Committee on . Salmon and Stream Enhancement ( the " Joint Committee!'). Under the federal Endangered Species Act ( ESA) the U. S. Fish & Wildlife Service . . ( F& WS) and the National Marine Fisheries Service ( NMFS) are responsible for identifying species that are threatened or endangered, and for developing programs to conserve and recover lhose species. F& WS and NMFS have now listed salmonids under the ESA on the entire Oregon Coast, the lower Columbia River ( including most of the Portland metropolitan area). the la math River basin, and in the upper Columbia and Snake River basins. More listings are expected within the next year. To date, the F& WS and NMFS generally have not had the resources to develop and implement effective recovery plans for fisheries. In addition, in many areas a large proportion of the habitat that list'ed'salmonids depend on is located on private lands, where the regulatory tools under the ESA are relatively ' ill- defined and indirect. Finally, federal agencies alone, even if they take an active regulatory approach. to recovery, will not restore listed salmonids. The federal ESA may work to prohibit certain actions, but there is simply too much habitat on private lands for restoration to succeed without pro- active involvement and incentives for individuals, groups, and local governments to take affirmative actions to restore habitat on working landscapes. In April, 1997 the State of Oregon and NMFS entered into a Memorandum of Agreement ( MOA) under which the State agreed to continue existing measures under the March 1997 Oregon Plan and to take certain additional actions to protect and restbre coho salmon on the Oregon Coast. On May 6, 1997, NMFS determined that the Oregon Coast Evolutionarily Significant Unit ( ESU) of coho salmon did not warrant listing as a threatened or endangered species under the ESA. On June 2, 1998, the US. District Court for Oregon ordered NMFS to reconsider its decision without taking into account any parts of the Oregon Plan or MOA that are not " current enforceable measures." The U. S. District Court for Oregon also held that the MOA was speculative, due to the fact that it provided for termination by either party on thirty days notice, and that therefore the MOA could not be considered by NMFS ' in its listing decision. Under court order, NMFS reconsidered its decision without taking into account the application in the future of the harvest and hatchery measures contained in the Oregon Plan, or the habitat improvement programs being undertaken under the Oregon Plan, or the commitments made by the State of Oregon in the MOA for improvement of applicable habitat measures. Accordingly, NMFS listed Oregon Coast .. . coho as threatened undefthe ESA on or about October 2, 1998. - The MOA provided for the State of Oregon to take actions necessary to ensfie that - Oregon Coast coho did not warrant listing as a threatened or endangered species under the federal ESA. Now that Oregon Coast coho are listed as a threatened species as a- result of the U. S. District Court's order, the central purpose of the MOA has been eliminated. Due to the uncertainties created by the District Court's decision and the increasing extent of salmonids listed or proposed for listing under the federal ESA, it is important that the status of the State of Oregon's substantive commitments under the MOA and the purpose of the Oregon Plan be clarified. Through this Executive Order, the State of Oregon reaffirms its intent to play the leading role in protecting and restoring Oregon Coast coho and other salmonids. through the implementation of the Oregon Plan. This Executive Order provides the framework and direction for state agencies to implement ( to the extent of their authorities) the Oregon Plan in a timely and effective manner. This Executive Order also provides a framework for extending the state's efforts beyond a focus on Oregon Coast coho, to watersheds and fisheries statewide. Consistent with the principle of adaptive management, this Order applies the experience gained to date in implementing the Oregon Plan to provide additional detailed direction to state agencies. Finally, this Executive Order establishes a public involvement process to prioritize continuing efforts under the Oregon Plan. NOW THEREFORE, IT IS HEREBY ORDERED AND DIRECTED: ( 1) Overall Direction ( a) Agencies of the State of Oregon will, consistent with their authorities, fully implement the state agency efforts described in the Oregon Plan and in this Executive Order. ( b) The overall objective for state agencies under the Oregon Plan and this Executive Order is to protect and restore salmonids and to improve water quality. ( c) The Governor will, in cooperation with the Joint Committee, IMST, affected state agencies, watershed councils, and other affected local entities and persons develop and implement, a process to set biological and habitat goals and objectives to protect and restore salmonids on a basin or regional basis as soon as practicable. Once these goals and objectives are established, they will be used by state agencies . . . to evaluate their regulatory and non- regulatory programs and measures relating to the protection and re'storation of salmonids. Through this on- going evaluation, state agencies will determine any changes to their programs or measures that may be necessary to meet the biological and habitat goals and objectives. In the interim, the following objectives in subsections ( d) and ( e) shall apply to agencies' implem'entation of the OregGn Plan and this Executive Order. . . ( d) Actions that state agencies take, fund and/ or authorize that are primarily for a purpose other than restoration of salmonids or the habitat they depend upon will, considering the anticipated duration and geographic scope of the actions: ( A) to the maximum extent practicable minimize and mitigate adverse effects of the actions on salmoni. ds or the habitat they depend on; and ( 8) not appreciably reduce the likelihood of the survival and recovery of salmonids in the wild. ( e) State agencies will take, fund and/ or authorize actions that are primarily for the purpose of restoring salmonids or the habitat they depend upon, including actions implementing the Oregon Plan, with the goal of producing a conservation benefit that ( if taken together with comparable and related actions by all persons and entities within the range of the species) is likely to result in sustainable population levels of salmonids in the foreseeable future, and in population levels of salmonids that provide substantial environmental, cultural and economic benefits to Oregonians in the long term. ( f) With the broadening of the Oregon Plan,' prioritizing all agency actions according to coho core areas is no longer appropriate. Each state agency participating in the Oregon Plan, in consultation with ODFW and other partners involved in the implementation of the Plan and through a public involvement process, will modify their existing work programs in the Oregon Plan to prioritize agency measures to protect and restore salmonids in a timely and effective manner. The work programs will continue to identify key specific outcomes, refine and improve designations of priority areas, and establish completion dates. These modifications will be submitted to the , Governor, the Joint Committee, and to the appropriate boards and commissions as soon as possible, but in no event later than June 1, 1999. Progress reports on action plans will be submitted to the Governor, the Joint Committee, and to the appropriate boards and commissions on an annual basis. In prioritizing their efforts,' state agencies shall consider how to maximize conservation -, benefits for salmonids and the habitat they depend on within limited resources and - . whether their- actions are likely to increase populations of salmonids in the foreseeable future. I p ( g) State agencies will work cooperatively with landowners, local entities and other persons taking actions to protect or restore salmonids. ( h) As the Oregon Plan grows in geographic scope and . in intensity of activity,' there is a growing need to streamline and prioritize state agency activity at the . regional level. One proposal has been to organize state natural resource agency field operations along hydrologic units. Therefore, state agencies will consider this proposal and, through the collective efforts of state agency directors, develop an organization plan that focuses state agency field effort on the activities and areas of highest priority under the Oregon Plan. ( i) State. agencies will continue to encourage and work with agencies of the U. S. government to implement the federal measures described in the Oregon Plan.. In addition, the state agencies will work with the federal government to develop additional means of protecting and restoring salmonids. Where appropriate, state agencies will request that federal agencies obtain incidental take permits under Section 7 of the federal ESA for state actions that ace funded or authorized by a , federal agency. ( j) State agencies will help support efforts to evaluate watershed conditions, and to develop'specific strategic plans to provide for flood management, water quality improvement, and salmonid restoration in basins around the state, including the Willamette basin through the Willamette Restoration Initiative. ( k) The IMST will continue to provide oversight to ensure the use of the best scientific information available as the basis for implementation of and for adaptive changes to the Oregon Plan. State agencies will ensure that the IMST receives data and other information reasonably required for its functions in a timely manner. The Governor's Natural Resources Office ( GNRO) has requested that the IMST's initial priority be review of the freshwater habitat needs of coho and the relationship between population levels, escapement levels, and habitat characteristics. The GNRO also will continue to request that the IMST annually review monitoring results and identify where the Oregon Plan warrants change for scientific or technical reasons and make recommend& ions to the appropriate agency on those adjustments that appear necessary. Agencies will report their responses to any recommendations by . . the IMST to the Governor and to the Joint Committee. Any other changes identified by the IMST as necessary to achieve properly functioning riparian and aquatic habitat conditions required to, protect and restore salmonids will be forwarded to the appropriate governmental entity for its consideration of the adoption of new, changed, or supplemental measures as rapidly as possible while providing for public involvement: Each state agency, by June 1, 1999, will ratify a monitoring team charter through an interagency memorandum. A draft of the charter is contained in the 1998 Oregon Plan Annual Report. ( I) Monitoring is a key element of the Oregon Plan. Each state agency will actively support the monitoring strategy described in the Oregon Plan. Each affected agency will participate on the monitoring team to coordinate activities and integrate analyses. Each agency will implement . an appropriate monitoring program to assess the effectiveness of their programs and measures in meeting the objectives set forth in the Oregon Planon an annual basis. In addition, agencies with regulatory programs that are included in the Oregon Plan will determine levels of compliance with regulatory standards and identify and act on opportunities to improve compliance levels: ( m) If information gathered regarding the effectiveness of measures in the Oregon Plan shows that existing strategies within state control are not achie, ving expected improvements and objectives, the agency( ies1 responsible for those measures will seek appropriate changes in their regulations, policies, programs, r-measures and other areas of the Oregon Plan, as required to protect and restore coho and other sal'monids. Such modification or supplementation will be done as rapidly as possible, consistent with public involvement. ( n) Agencies are using geographically- referenced data in their efforts under the Oregon Plan, and will be using Geographic Information Systems ( GIs) in the analysis of these , data. In doing so, the State GIs Plan, developed by the Oregon Geographic lnformation Council ( OGIC) ( see Executive Order 96- 40) will be followed, with specific adherence to the Plan guidance on data documentation, coordination and data sharing. The agency with primary responsibility for gathering and updating the specific data will be responsible for meeting the requirements of the Plan, and to ensure coordination- with OGIC, the State Service Center for GIs and other' cooperating agencies. In addition, state agencies will cooperate with the Governor's Watershed Enhancement Board ( GWEB), Soil and. Water Conservation Districts ( SWCDs), local waters$ ed councils, landowners and others in making these essential data available. ( 0) Geographically- based strategies to assess and achieve habitat needs and adequate escapement levels will be used, and the state agencies will continue with the development of standardized watershed assessment protocols, including a -- cumulative effects assessment. State agencies will also continue with the development of habitat restoration guides to evaluate and direct habitat restoration efforts. ( 2) Continuation and Expansion of Existing Efforts. Without limiting the generality of section ( l)( a) of this Executive Order, the following subsections of this Executive Order describe some of the many efforts in the Oregon Plan where the initial phase of work has been completed, and where efforts will be continued. ( a) The Oregon Fish & Wildlife Commission ( OFWC), the Oregon Department of Fish & Wildlife ( ODFW), and the Pacific Fishery Management Council ( PFMC) are managing ocean and terminal fisheries according to the measures set forth in the Oregon Plan ( ODFW I- A. l and Ill- A. l). These measures set a maximum mortality rate ( resulting from other fisheries) for any of four disaggregated stocks of coho of fifteen percent ( 1 5%) under poor ocean conditions. In 1997, the mortality rate. from harvest is estimated to have been between nine and eleven percent ( 9- 1 1 %). ODFW and OFWC will continue these measures in state waters, and will actively support continued implementation of the ocean harvest measures by the PFMC ( Amendment 13 to the Council's salmon management plan) until and unless a different management regime agreeable to NMFS is adopted. ( b) The OFWC and ODFW will ensure that the fish hatchery measures set forth in the Oregon Plan are continued by the OFWC and ODFW. ODFW is marking all hatchery coho on the Oregon Coast. This marking will allow increased certainty in estimating hatchery stray rates beginning in 1999. Available data on hatchery stray rates for coho and steelhead are being provided to NMFS on an annual basis. The number of hatchery coho released is estimated to have been 1.7 million in 1998 - substantially below the level called for in the Oregon Plan. This number will be reduced to 1.2 million in 1999. In addition, ODFW has, and will continue to provide. annual reports regarding: ( i) the number of juvenile hatchery coho that are released by brood year, locations and dates of release, life stage, and broodstock origin; ( ii) the number of adult coho taken for broodstock for each hatchery, the location and date of collection, and the origin ( hatchery or natural); ( iii) the number of hatchery coho . . estimated to have spawned in natural habitat by basin; ( iv) the estimated percentage of hatchery coho% the total natural spawning population; and ( v) the mortality of naturally- spawning coho resulting from each fishery. NMFS may provide comments about hatchery prograk affecting coho to ODFW, with any concerns to be resolved between NMFS and ODFW. - - ( c) ln addition to recent modifications to hatchery practices and programs, a new vision is needed for how Oregon will utilize hatcheries in the best and most effective manner. Therefore, the ODFW and the OFWC shall engage in a process to create a strategic plan for fish hatcheries in Oregon over the next decade ( including state and federally- funded hatcheries, private hatcheries, and the STEP program). The essential elements of this process are as follows: ( i) Impartial analysis - conduct an impartial analysis of the scientific bases, and the social and economic effects of Oregon hatchery programs utilizing existing analyses and review where feasible, but conducting new analyses if necessary; ( ii) Review the Wild Fish Management Policy ( WFMP) - because the future plan for hatcheries in Oregon is dependent on implementation of the WFMP, ODFW shall conduct a science and stakeholder review to determine if this significant policy should be revised and shall make any revision by July 2000; ( iii) Frame alternative strategies -- convene a group of stockholders to . frame alternative strategies, including outcomes and descriptions, of how hatcheries will be used in Oregon over the next decade ( these strategies will address the use of hatcheries for wild fish population recovery including supplementation, research and monitoring, public education, and sport and commercial fishing opportunities); ( iv) Public review and selection of a strategy -- the OFWC shall, after public review and ' ;-'-!&%; f$'. i comment, adopt a strategic plan to guide development of future hatchery programs, incorporating the strategy developed and adopted in accordance with subpart ( iii) of this paragraph. ( d) Criteria and guidelines directing the design of projects that may affect fish passage have been established in a Memorandum of Understanding ( MOU) between the Oregon Department of Transportation ( ODOT), ODFW, the Oregon Department of Forestry ( ODF), the Oregon Department of Agriculture ( ODA), the Division of State Lands ( DSL) and the Federal Highway Administration. These guidelines apply to the design, construction and consultations of projects affecting fish passage. Under the MOU, projects requiring regulatory approvals that follow these criteria and guidelines are expedited. Oregon agencies will continue to provide technical assistance to ensure that the criteria and guidelines are applied appropriately in restoration projects, as well as any other projects that may affect fish passage through road crossings and similar structures. ODFW will work with state agencies, local governments, and watershed councils to ensure that Oregon's standards for fish passage set forth in Exhibit A to the MOU are understood and are implemented. - ( e) Fish presence, stream habitat, road and culvert surveys have been conducted for roads within ODOT jurisdiction and county roads in coastal basins, the Lower Columbia basin, the Willamette basin, and the Grande Ronbe/ lmnaha basins. Among the results of these surveys is the finding that culvert barriers to fish passage affect a substantial quantity of salmonid habitat. For example, surveys of county and state highways in western Oregon found over 1,200 culverts that are barriers to passage. As a result, ODOT is placing additional priority on restoring fish access. For 1998, ODOT repaired or replaced 35 culverts restoring access to 101 miles of salmonid habitat. For 1999, the Oregon Transportation Commission will be asked to fund approximately $ 4.0 million for culvert modification. ODOT and the Commission will continue to examine means to speed restoration of fish passage and to coordinate priorities with ODFW. ( f) Draft watershed assessment protocols have been developed and are being field tested. Beginning in 1999, SWCDs, watershed councils and others will be able to use the protocols as the basis for action plans to identify and prioritize opportunities to protect and restore salmonids. Watershed action plans have already been completed in a number of basins including the Rogue, Coos, Coquille and Grande Ronde. State agencies will work to support these watershed assessments and plans to the maximum extent practicable. Where watershed action plans have been developed under the protocols, GWEB will ensure that projects funded through the Watershed Improvement Grant Fund are consistent with watershed action plans, and other state agencies will work with SWCDs and watershed councils to ensure that activities they authorize, fund or undertake are consistent with watershed action plans to the maximum extent practicable. ( g) The State of Oregon has developed interim aquatic habitat restoration and enhancement guidelines for 1998. State agencies involved with restoration activities ( ODFW, ODF, DSL, ODA, DEQ, and GWEB) will continue to develop and refine the interim guidelines for final publication in April 1999. The guidelines will be applied in restoration activities funded or authorized by state agencies. The purpose of ' the guidelines will be to define aquatic restoration and to identify and encourage aquatic habitat restoration techniques to restore salmonids. . . ( h) ODA and O ~ hFave each entered into a Memorandum of Understanding with the Oregon Department'of Environmental Quality relating to the development of . Total Maximum Daily Loads ( TMDLs) and Water Quality Management Area Plans ( WQMAPs). O Dw~ ill adopt. a nd implement WQMAPs ( through the Healthy Streams Partnership) and ODF , will review the adequacy of forest practices rules to meet water quality standards. ODF and ODA will evaluate the effectiveness of these measures in achieving water quality standards on a regular basis and implement any changes required to meet the standards. ( i) Agencies are implementing a coordinated monitoring program, as described in the Oregon Plan. This program includes technical support and standardized protocols for watershed councils, stream habitat surveys, forest practice effectiveness monitoring, water withdrawal monitoring, ambient water quality monitoring, and biotic index studies, as well as fish presence surveys and salmonid abundance and survival monitoring in selected subbasins. State agencies are also' working to coordinate monitoring efforts by state, federal, and local entities, including watershed councils. State agencies will work actively to ensure that the monitoring measures' in the Oregon Plan are continued. - .. ( j) GWEB has put into place new processes for identifying and coordinating the delivery of financial and technical assistance to individuals, agencies, watershed councils and soil and water conservation districts as they implement watershed ' restoration projects to improve water quality and restore aquatic resources. Over $ 25 ' million has been distributed for watershed restoration projects in the last ten years. During the present ( 1 997- 99 biennium) GWEB has awarded over $ 1 2 million dollars in f- state and federal funds for technical'assistance and watershed restoration activities to implement the Oregon Plan. GWEB and state agencies will continue to seek financial resources to be allocated by GWEB for watershed restoration activities at the local and. statewide levels. ( k) State agencies will continue to encourage, support and work to provide incentives for local, tribal, and private . efforts to implement the Oregon Plan. In addition, state agencies will continue to provide financial assistance to local entities for projects to protect and restore salmonids to the extent consistent with their budgetary and legal authorities, and consistent with their work programs in the Oregon Plan. To the. maximum extent practicable, state agencies will also provide technical assistance and planning tools to provide local conservation groups to assist in and target watershed restoration efforts. These efforts ( during 1996 and 1997) are reported in " The Oregon. Plan for Salmon and Watersheds: Watershed Restoration Inventory, 1998." ~ u s c afe w of the important efforts that have been completed include: ( A) Eighty- two watershed councils have joined with forty- five Soil and Water Conservation Districts as well as private and public landowners to implement on- the- ground projects' to protect and restore salmonids. During 1996 and 1997, a reported $ 27.4 million was spent on 1,234 watershed restoration projects on non-federal lands. Both the amount spent and the number of projects represent significant increases ( of over 300 percent) over prior years. In 1996- 97, watershed councils, SWCDs and other organizations and individuals completed: ( i) 138 stream fencing projects, involving at least 301 miles of streambank; ( ii) 196 riparian area planting projects, involving at least 11 1 miles of streams; and ( iii) 458 instream habitat improvement projects. . . . ( B) Private and state forest landowners are implementing key efforts under the Oregon Plan, including the road risk and remediation program ( ODF- 1 and 2). Under this effort in 1996 and 1997, close to 4,000 miles of roads'have been surveyed to identify risks that the roads may pose to salmonid habitat. As the risks are identified, they are then prioritized for remediation following an established. protocol. Already, 52 miles of forest roads have been closed, 843 miles of road repair and reconstruction projects to - protect salmonid habitat have been completed, and an additional 14 miles of roads have been decommissioned or relocated.. In addition, 530 culverts have been replaced, upgraded or installed for fish passage purposes, improving access to a reported 146 stream miles. ( C) Organizations working in Tillamook County have developed the I ." J aw#~ t Tillamook County Performance Partnership. The Partnership is implementing the \*. Tillamook Bay National Estuary Program by addressing water quality, fisheries, floodplain management and economic development in the county. Among the actions that the Partnership has already accomplished are: ( i) the closure of seven miles of degraded forest roads and the rehabilitation of 469 miles of roads to meet current standards, at a cost of $ 1 8 million; ( ii) the fencing of 53 miles of streambank, and the construction of three cattle bridges and 100 alternative cattle watering sites, at a cost of $ 214,000; and ( iii) the completion of 24 instream restoration projects and 34 barbs protecting 4,200 feet of streambank, at a cost of $ 1.3 million dollars. ( D) The Confederated Tribes of the Grande Ronde Community of Oregon have completed a forest management plan that establishes standards for the protection of aquatic resources that are comparable to those found in the Aquatic Conservation Strategy ' of the Northwest Forest Plan. . % ( E) A combination of funding from the Oregon Wildlife Heritage Foundation and the National Fish and Wildlife Heritage Foundation ( private, non- profit organizations) is provi, ding support for seven biologists to design restoration projects. These projects are prioritized based on stream surveys, and are carried out with the voluntary participation and support of landowners. A ten- year monitoring plan has been funded- and implemented to determine project effectiveness: ( F) The Oregon Cattlemen's Association has implemented its WESt Program that is designed to help landowners better understand their watersheds and stream functions through assessments and monitoring. h he WESt Program brings landowners together along stream reaches, and offers a series of workshops, conducted on a site specific basis, free of charge. The workshops include riparian ecology, setting goals and objectives, Proper Functioning Condition ( PFC), data. collection and monitoring. Over 25 workshops have been held, with attendance ranging from 5 to 30 landowners per workshop. The WESt Program is sponsored by the Oregon Cattlemen's Association, DEQ, Oregon State University, and GWEB. ( G) Within the Tillamook State Forest road network 1,902 culverts have been replaced or added to'improve road drainage and to disconnect storm water runoff from roads reducing stream sediment impacts. Additionally, some of these culverts also improved fish passage at stream crossings. In this process, ODF has also replaced six culverts with bridges improving fish passage to approximately four miles of stream. The Tillamook State Foresl in conjunction with many partners, such F-as the Association of Northwest Steelheaders, G W EB, Simpson Timber Company, Tillamook County, the FishAmerica Foundation, Hardrock Construction Company, the Oregon Wildlife Heritage Foundation, the F& WS, the Oregon Youth Conservation Corps, Columbia Helicopters and Terra Helicopters, has also recently completed instream placement of over 400 rootwads, trees and boulders at a cost of $ 300,000 for habitat enhancement. ( 3) Key Agency Efforts. Continuation and completion of the following state agency efforts is critical to the success of the Oregon Plan. State agencies will make continuation or completion ( as appropriate) of the following efforts a high priority. ( a) The State of Oregon and the US. Department of Agriculture have entered into a Conservation Reserve Enhancement Program ( CREP). This cost- share program, one of the first of its kind, . will be used to reduce the impacts of agricultural practices through water quality. add habitat improvement. The objectives of the CREP are to: ( i) provide incentives'for farmers and ranchers to establish riparian buffers; ( ii) protect - . and restore at least 4,000 miles of stream habitat by providing up to 95,000 acres of riparian buffeis; ( i4) restore up to 5,000 acres of wetlands that will benefit salmonids; and ( iv) provide a mechanism for farmers and ranchers to comply with Oregon's ,- Senate Bill 101 0 ( 1 993 Or. Laws, ch. 263). ( b) ODF will work with non- industrial forest landowners to'administer the Stewardship Incentive Program and the Forest Resources Trust programs to protect and restore riparian and wetland areas that benefit salmonids. ( c) The Oregon Board of Forestry will determine, with the assistance of an advisory committee, to what extent changes to forest practices are needed to meet state water quality standards and to protect and restore salmonids. A substantial body of information regarding the effectiveness of current practices is being . developed. This information includes: ( i) the IMST report regarding . the role of forest practices and forest habitat in protecting and restoring salmonids; and ( ii) a series of - monitoring projects that include the Storms of 1996 study, a riparian areas study, a stream temperature study, and a road drainage study. Using this information, as well as other available scientific information including scientific information from NMFS, the advisory committee will make recommendations to the Board at both site and watershed scales on threats to salmonid habitat relating to sediment, water temperature, freshwater habitat needs, roads and fish passage. Based on the advisory committee's recommendations and other scientific information, the Board will make every effort to make its determinations by June 1999. The Board may . . determine that the most effective means of achieving any necessary changes to . - d;.~ .;* i;. z . I:@;.. %- .~ + k forest practices is through regulatory changes, statutory changes or through other programs . including programs to create incentives for forest landowners. In the event that the Board determines that legislative changes. are necessary to carry out its determinations, the Board will transmit any recommendations for such changes to the . Governor and to the Joint Committee at the earliest possible date. ( d) Consistent with administrative rule, and statutory and constitutional mandates for the management of state forests, ODF State Forest management plans will include an aquatic conservation strategy that has a high likelihood of protecting and restoring properly functioning aquatic habitat for salmonids on state forest lands. ( e) ODF will present to NMFS a Habitat Conservation Plan ( HCP) under Section 10 of the federal ESA that includes the Clatsop and Tillamook State Forests. ODF has already completed scierkific review and has public review underway for this draft HCP. The scientific and public review comments will be considered by ODF in . . completing the draft HCP. The draft HCP will be presented to NMFS by June 1999. An HCP for the ~ jliotSt tate Forest was approved by the US. Fish & Wildlife Service in 1995. In October af 1997, ODF and DSL forwarded the Elliott State Forest HCP to NMFS with the request that it be reviewed to determine whether it has a high likelihood of protecting and restoring properly functioning aquatic habitat conditions on state forest lands necessary to protect and restore salmonids. Based on discussions surrounding the NMFS review, ODF and DSL will determine what revisions, if any, are required to the Elliott HCP and/ or Forest Management Plan to ensure a high likelihood of protecting and restoring properly functioning aquatic habitat for salmonids. ( f) Before the OFWC adopts and implements fishery regulations that may result in taking of coho, ODFW will provide NMFS with'all available scientific information and analyses pertinent to the proposed regulation where the harvest measures are not under the jurisdiction of the PFMC, including results of the Oregon Plan monitoring and evaluation program. This information, together with the proposed regulation and supporting analysis, will be provided at least two weeks prior to the OFWC's action, to give NMFS time to review and comment on the proposed regulations. ( g) ODFW will evaluate the effects of predation on salmonids, and . will . work with . affected federal agencies to determine whether changes to programs and law relating to predation are warranted in order to protect and restore salmonids. P ( h) Under Oregon Senate Bill 101 0 ( 1 993 Or. Laws, ch. 2631, ODA will adopt Agricultural Water Qualify Management Area Plans ( AWQMAPs) for Tier I and Tier ll watersheds by the end of 2002. The AWQMAPs will be designed and implemented to meet load allocations for agriculture needed to achieve state water quality . . standards. In addition, ODA will work with ODFW, DEQ, GWEB, SWCDs, federal . agencies and watershed councils to determine to what extent additional measures related to achieving properly functioning riparian and aquatic habitat on agricultural lands are needed to protect and restore salmonids, giving attention first to priority areas identified in. the Oregon Plan. In the event ODA is unable to reach a consensus regarding such measures, ODA will ask the IMST to review areas of substantive ' scientific disagreement and to'make recommendations to ODA regarding how they should be resolved. In the event that legislative changes are needed to implement such measures, ODA will transmit any recommendations for such changes to. the Governor and to the Joint Committee at the earliest possible date. In addition, any measures identified as rieeded by ODA will be implemented at the earliest practicable time. * . ( i) ODFW will expedite its applications for instream water rights and OWRD will process such applications promptly where flow deficits are identified as adversely affecting salmonids, and where such rights. are not already in place. The Oregon - water Resources Department ( OWRD) and the Oregon Water Resources Commission ( OWRC) will- also seek to facilitate flow restoration targeted to streams identified by OWRD and ODFW as posing the most critical low- flow barriers to salmonids. In addition, where necessary, OWRD will continue to work with the Oregon State Police to provide enforcement of water use. Where illegal water uses are identified, OWRD will ensure outcomes consistent with maintenance and restoration of flows. ( j) The Oregon Environmental Quality commission ( EQC). and DEQ will evaluate and will make every effort to utilize their authorities to continue to provide additional protection to . priority areas ( as determined under section 1 ( f) of this Executive Order), including in- stream flow protection under state law, and antidegradation policy under . the federal Clean Water Act ( including Outstanding Resource Waters designations . and high quality waters designations). . ( k) DSL has proposed to adopt changes to its Essential Salmonid Habitat rules that will provide additional protection for spawning and rearing areas of anadromous salmonids. In addition, ODFW and DSL will consult with the OWRC to determine where it is necessary to administratively close priority areas ( including ' work under General Authorizations) to fill and removal activities in order to protect salmonids. . . DSL, ODFW, ODF and ODA also will work together to identify means of regulating the . uy- w :.-:: st. removal of organic material ( such as large woody debris) from streams where such removal would adversely affect salmonids and would not be contrary to other agency mandates. ( I) DSL will seek the advice of the IMST regarding whether gravel removal affects gravel and/ or sediment budgets in a manner that adversely affects salmonids. ( m) The Department of Land Conservation and ~ e v e l o p r n e n t ' ( ~ ~ acn~ d ) th, e Land Conservation- and Development Commission ( LCDC) will evaluate and, to the extent feasible, speed implementation of existing Goal 5 requirements for riparian corridors. ( n) DLCD, DEQ, ODF, ODA, ODFW, and DSL and their respective boards and commissions will evaluate and implement programs to protect and restore riparian vegetation for the purposes of achieving statewide water quality standards and . . protecting and restoring a aquatic habitat for salmonids. ' ( 0) DLCD, with, the assistance of DSL and ODFW, and in consultation with coastal cities and counties, shall review the requirements of Statewide Planning Goal i 6 as they pertain to estuarine resources important to the restoration of salmonids, and shall, report its findings to LCDC for its consideration. ( p) The Oregon State Police will work to facilitate the existing cooperative relationship with the NMFS Office of ~ a Ewnfo rcement, as well as tomaintain cooperation with other enforcement entities, in order to enhance law enforcement, public awareness and voluntary compliance related to harvest, habitat and other issues addressed in the Oregon Plan. ( q) The Oregon Parks and Recreation Department will continue to work to p. rovide information and education to the public on salmon and steelhead needs through park programs and interpretive aids. ( r) The Oregon Marine Board will work to ensure fish friendly boating and to develop boating facilities that protect salmonids. ( s) State natural resource agencies will continue, to the extent feasible, to support watershed councils by providing technical assistance to develop watershed assessments, restoration plans and to develop watershed priorities to benefit 7- salmonids. In addition, state natural resource agencies will work'on a larger . .:.... watershed scale to develop basin- wide restoration priorities. ( 4) Future Modifications; Public Involvement for the Oregon Plan Generally. The GNRO will solicit public co'mments and input from participants in the Oregon Plan regarding whether there are refinements or changes to the Plan and/ or the organizational framework for implementing the Plan that are necessary or desirable based on the experience gained over the past three years, or resulting from the widespread listings and proposed listings of salmon and trout under the federal ESA. Based on this public involvement, the GNRO will provide a report and recommendations to the Governor and the Joint Committee regarding whether modifications are necessary to the Oregon Plan in order to protect and restore coho and other salmonids.

Office of the Governor Year: 1999, 2005, 2004 KCAMATH FALLS. QREEON THE OREGON PLAN FOR SALMON AND WATERSHEDS The purpose of the Oregon Plan for Salmon and Watersheds ( the " Oregon Plan") as stated in the Plan and reaffirmed in this Executive Order is to restore Oregon's wild salmon and trout populations and fisheries to sustainable and productive levels that will provide substantial environmental, cultural, and economic benefits and to improve water quality. The Oregon Plan is a long- term, ongoing effort that began as a focused set of actions by state, local, tribal and private organizations and individuals in October of 1995. The Oregon Plan first addressed coho salmon on the Oregon Coast, was then broadened to include steelhead trout on the coast and in the Lower Columbia River, and is now expanding to all at- risk wild salmonids throughout the state. The Oregon Plan addresses all factors for decline of these species, including watershed conditions arid fisheries, to the extent those factors can be affected by the state. The Oregon Plan was endorsed and funded by the Oregon Legislature in 1997 through Oregon Senate Bill 924 ( 1 997 Or. Laws, ch. 7) and House Bill 3700 ( 1 997 Or. Laws, ch.' 8). The Oregon Plan is described in two principal documents: " The Oregon Plan," dated March 1997, and " The Oregon Plan for Salmon and Watersheds, Supplement I - steelhbad," dated January 1998. As used in this Executive Order, + the Oregon Plan also incorporates the Healthy Streams Partnership ( Oregon Senate Bill 101 0, 1 993- Or. Laws, ch. 263). The Oregon Plan is a cooperative effort of state, local, federal, tribal and private organizations and individuals. Although the Oregon Plan contains a strong foundation of protective regulations -- continuing existing regulatory programs and speeding the implementation of others - an essential principle of the Plan is the need to move beyond prohibitions and to encourage efforts to improve conditions for salmon through non- regulatory means. Many of the most significant contributions to the Oregon Plan are private and quasi- governmental efforts to protect and . restore salmon on working landscapes, including efforts by watershed councils. Salmon and trout restoration requires action and sacrifice across the entire economic and geographic spectrum of Oregon. The commercial and sport fishing industries in Oregon have been heavily affected by complete or partial closures of fisheries. The forest industry operates under the Oregon Forest Practices Act, and has contributed substantially to salmon recovery through habitat restoration projects on private lands and by funding a large pan of the state recovery efforts. The agriculture and mining industries are also taking actions that will protect and restore salmon and trout habitat and improve water quality ( including financial support of restoration efforts by the mining industry). Urban areas are developing water conservation programs, spending funds for wastewater treatment improvements to reduce point source pollution, reducing non- point source pollution and reducing activities that degrade riparian areas. All citizens of Oregon share responsibility for declining populations of wild salmon and trout, and it is important that there be both a broad commitment to reversing these historic trends and a sense that the burdens of restoration are being shared by all of society. It is also important that there be independent scientific oversight of the Oregon Plan. This oversight is being provided by the Independent Mutidisciplinary Science Team ( IMST), established under Oregon Senate Bill 924 ( 1 997 Or. Laws, ch. 7). ~ d'ditional legislative oversight for the Oregon Plan is being provided by the Joint Legislative Committee on . Salmon and Stream Enhancement ( the " Joint Committee!'). Under the federal Endangered Species Act ( ESA) the U. S. Fish & Wildlife Service . . ( F& WS) and the National Marine Fisheries Service ( NMFS) are responsible for identifying species that are threatened or endangered, and for developing programs to conserve and recover lhose species. F& WS and NMFS have now listed salmonids under the ESA on the entire Oregon Coast, the lower Columbia River ( including most of the Portland metropolitan area). the la math River basin, and in the upper Columbia and Snake River basins. More listings are expected within the next year. To date, the F& WS and NMFS generally have not had the resources to develop and implement effective recovery plans for fisheries. In addition, in many areas a large proportion of the habitat that list'ed'salmonids depend on is located on private lands, where the regulatory tools under the ESA are relatively ' ill- defined and indirect. Finally, federal agencies alone, even if they take an active regulatory approach. to recovery, will not restore listed salmonids. The federal ESA may work to prohibit certain actions, but there is simply too much habitat on private lands for restoration to succeed without pro- active involvement and incentives for individuals, groups, and local governments to take affirmative actions to restore habitat on working landscapes. In April, 1997 the State of Oregon and NMFS entered into a Memorandum of Agreement ( MOA) under which the State agreed to continue existing measures under the March 1997 Oregon Plan and to take certain additional actions to protect and restbre coho salmon on the Oregon Coast. On May 6, 1997, NMFS determined that the Oregon Coast Evolutionarily Significant Unit ( ESU) of coho salmon did not warrant listing as a threatened or endangered species under the ESA. On June 2, 1998, the US. District Court for Oregon ordered NMFS to reconsider its decision without taking into account any parts of the Oregon Plan or MOA that are not " current enforceable measures." The U. S. District Court for Oregon also held that the MOA was speculative, due to the fact that it provided for termination by either party on thirty days notice, and that therefore the MOA could not be considered by NMFS ' in its listing decision. Under court order, NMFS reconsidered its decision without taking into account the application in the future of the harvest and hatchery measures contained in the Oregon Plan, or the habitat improvement programs being undertaken under the Oregon Plan, or the commitments made by the State of Oregon in the MOA for improvement of applicable habitat measures. Accordingly, NMFS listed Oregon Coast .. . coho as threatened undefthe ESA on or about October 2, 1998. - The MOA provided for the State of Oregon to take actions necessary to ensfie that - Oregon Coast coho did not warrant listing as a threatened or endangered species under the federal ESA. Now that Oregon Coast coho are listed as a threatened species as a- result of the U. S. District Court's order, the central purpose of the MOA has been eliminated. Due to the uncertainties created by the District Court's decision and the increasing extent of salmonids listed or proposed for listing under the federal ESA, it is important that the status of the State of Oregon's substantive commitments under the MOA and the purpose of the Oregon Plan be clarified. Through this Executive Order, the State of Oregon reaffirms its intent to play the leading role in protecting and restoring Oregon Coast coho and other salmonids. through the implementation of the Oregon Plan. This Executive Order provides the framework and direction for state agencies to implement ( to the extent of their authorities) the Oregon Plan in a timely and effective manner. This Executive Order also provides a framework for extending the state's efforts beyond a focus on Oregon Coast coho, to watersheds and fisheries statewide. Consistent with the principle of adaptive management, this Order applies the experience gained to date in implementing the Oregon Plan to provide additional detailed direction to state agencies. Finally, this Executive Order establishes a public involvement process to prioritize continuing efforts under the Oregon Plan. NOW THEREFORE, IT IS HEREBY ORDERED AND DIRECTED: ( 1) Overall Direction ( a) Agencies of the State of Oregon will, consistent with their authorities, fully implement the state agency efforts described in the Oregon Plan and in this Executive Order. ( b) The overall objective for state agencies under the Oregon Plan and this Executive Order is to protect and restore salmonids and to improve water quality. ( c) The Governor will, in cooperation with the Joint Committee, IMST, affected state agencies, watershed councils, and other affected local entities and persons develop and implement, a process to set biological and habitat goals and objectives to protect and restore salmonids on a basin or regional basis as soon as practicable. Once these goals and objectives are established, they will be used by state agencies . . . to evaluate their regulatory and non- regulatory programs and measures relating to the protection and re'storation of salmonids. Through this on- going evaluation, state agencies will determine any changes to their programs or measures that may be necessary to meet the biological and habitat goals and objectives. In the interim, the following objectives in subsections ( d) and ( e) shall apply to agencies' implem'entation of the OregGn Plan and this Executive Order. . . ( d) Actions that state agencies take, fund and/ or authorize that are primarily for a purpose other than restoration of salmonids or the habitat they depend upon will, considering the anticipated duration and geographic scope of the actions: ( A) to the maximum extent practicable minimize and mitigate adverse effects of the actions on salmoni. ds or the habitat they depend on; and ( 8) not appreciably reduce the likelihood of the survival and recovery of salmonids in the wild. ( e) State agencies will take, fund and/ or authorize actions that are primarily for the purpose of restoring salmonids or the habitat they depend upon, including actions implementing the Oregon Plan, with the goal of producing a conservation benefit that ( if taken together with comparable and related actions by all persons and entities within the range of the species) is likely to result in sustainable population levels of salmonids in the foreseeable future, and in population levels of salmonids that provide substantial environmental, cultural and economic benefits to Oregonians in the long term. ( f) With the broadening of the Oregon Plan,' prioritizing all agency actions according to coho core areas is no longer appropriate. Each state agency participating in the Oregon Plan, in consultation with ODFW and other partners involved in the implementation of the Plan and through a public involvement process, will modify their existing work programs in the Oregon Plan to prioritize agency measures to protect and restore salmonids in a timely and effective manner. The work programs will continue to identify key specific outcomes, refine and improve designations of priority areas, and establish completion dates. These modifications will be submitted to the , Governor, the Joint Committee, and to the appropriate boards and commissions as soon as possible, but in no event later than June 1, 1999. Progress reports on action plans will be submitted to the Governor, the Joint Committee, and to the appropriate boards and commissions on an annual basis. In prioritizing their efforts,' state agencies shall consider how to maximize conservation -, benefits for salmonids and the habitat they depend on within limited resources and - . whether their- actions are likely to increase populations of salmonids in the foreseeable future. I p ( g) State agencies will work cooperatively with landowners, local entities and other persons taking actions to protect or restore salmonids. ( h) As the Oregon Plan grows in geographic scope and . in intensity of activity,' there is a growing need to streamline and prioritize state agency activity at the . regional level. One proposal has been to organize state natural resource agency field operations along hydrologic units. Therefore, state agencies will consider this proposal and, through the collective efforts of state agency directors, develop an organization plan that focuses state agency field effort on the activities and areas of highest priority under the Oregon Plan. ( i) State. agencies will continue to encourage and work with agencies of the U. S. government to implement the federal measures described in the Oregon Plan.. In addition, the state agencies will work with the federal government to develop additional means of protecting and restoring salmonids. Where appropriate, state agencies will request that federal agencies obtain incidental take permits under Section 7 of the federal ESA for state actions that ace funded or authorized by a , federal agency. ( j) State agencies will help support efforts to evaluate watershed conditions, and to develop'specific strategic plans to provide for flood management, water quality improvement, and salmonid restoration in basins around the state, including the Willamette basin through the Willamette Restoration Initiative. ( k) The IMST will continue to provide oversight to ensure the use of the best scientific information available as the basis for implementation of and for adaptive changes to the Oregon Plan. State agencies will ensure that the IMST receives data and other information reasonably required for its functions in a timely manner. The Governor's Natural Resources Office ( GNRO) has requested that the IMST's initial priority be review of the freshwater habitat needs of coho and the relationship between population levels, escapement levels, and habitat characteristics. The GNRO also will continue to request that the IMST annually review monitoring results and identify where the Oregon Plan warrants change for scientific or technical reasons and make recommend& ions to the appropriate agency on those adjustments that appear necessary. Agencies will report their responses to any recommendations by . . the IMST to the Governor and to the Joint Committee. Any other changes identified by the IMST as necessary to achieve properly functioning riparian and aquatic habitat conditions required to, protect and restore salmonids will be forwarded to the appropriate governmental entity for its consideration of the adoption of new, changed, or supplemental measures as rapidly as possible while providing for public involvement: Each state agency, by June 1, 1999, will ratify a monitoring team charter through an interagency memorandum. A draft of the charter is contained in the 1998 Oregon Plan Annual Report. ( I) Monitoring is a key element of the Oregon Plan. Each state agency will actively support the monitoring strategy described in the Oregon Plan. Each affected agency will participate on the monitoring team to coordinate activities and integrate analyses. Each agency will implement . an appropriate monitoring program to assess the effectiveness of their programs and measures in meeting the objectives set forth in the Oregon Planon an annual basis. In addition, agencies with regulatory programs that are included in the Oregon Plan will determine levels of compliance with regulatory standards and identify and act on opportunities to improve compliance levels: ( m) If information gathered regarding the effectiveness of measures in the Oregon Plan shows that existing strategies within state control are not achie, ving expected improvements and objectives, the agency( ies1 responsible for those measures will seek appropriate changes in their regulations, policies, programs, r-measures and other areas of the Oregon Plan, as required to protect and restore coho and other sal'monids. Such modification or supplementation will be done as rapidly as possible, consistent with public involvement. ( n) Agencies are using geographically- referenced data in their efforts under the Oregon Plan, and will be using Geographic Information Systems ( GIs) in the analysis of these , data. In doing so, the State GIs Plan, developed by the Oregon Geographic lnformation Council ( OGIC) ( see Executive Order 96- 40) will be followed, with specific adherence to the Plan guidance on data documentation, coordination and data sharing. The agency with primary responsibility for gathering and updating the specific data will be responsible for meeting the requirements of the Plan, and to ensure coordination- with OGIC, the State Service Center for GIs and other' cooperating agencies. In addition, state agencies will cooperate with the Governor's Watershed Enhancement Board ( GWEB), Soil and. Water Conservation Districts ( SWCDs), local waters$ ed councils, landowners and others in making these essential data available. ( 0) Geographically- based strategies to assess and achieve habitat needs and adequate escapement levels will be used, and the state agencies will continue with the development of standardized watershed assessment protocols, including a -- cumulative effects assessment. State agencies will also continue with the development of habitat restoration guides to evaluate and direct habitat restoration efforts. ( 2) Continuation and Expansion of Existing Efforts. Without limiting the generality of section ( l)( a) of this Executive Order, the following subsections of this Executive Order describe some of the many efforts in the Oregon Plan where the initial phase of work has been completed, and where efforts will be continued. ( a) The Oregon Fish & Wildlife Commission ( OFWC), the Oregon Department of Fish & Wildlife ( ODFW), and the Pacific Fishery Management Council ( PFMC) are managing ocean and terminal fisheries according to the measures set forth in the Oregon Plan ( ODFW I- A. l and Ill- A. l). These measures set a maximum mortality rate ( resulting from other fisheries) for any of four disaggregated stocks of coho of fifteen percent ( 1 5%) under poor ocean conditions. In 1997, the mortality rate. from harvest is estimated to have been between nine and eleven percent ( 9- 1 1 %). ODFW and OFWC will continue these measures in state waters, and will actively support continued implementation of the ocean harvest measures by the PFMC ( Amendment 13 to the Council's salmon management plan) until and unless a different management regime agreeable to NMFS is adopted. ( b) The OFWC and ODFW will ensure that the fish hatchery measures set forth in the Oregon Plan are continued by the OFWC and ODFW. ODFW is marking all hatchery coho on the Oregon Coast. This marking will allow increased certainty in estimating hatchery stray rates beginning in 1999. Available data on hatchery stray rates for coho and steelhead are being provided to NMFS on an annual basis. The number of hatchery coho released is estimated to have been 1.7 million in 1998 - substantially below the level called for in the Oregon Plan. This number will be reduced to 1.2 million in 1999. In addition, ODFW has, and will continue to provide. annual reports regarding: ( i) the number of juvenile hatchery coho that are released by brood year, locations and dates of release, life stage, and broodstock origin; ( ii) the number of adult coho taken for broodstock for each hatchery, the location and date of collection, and the origin ( hatchery or natural); ( iii) the number of hatchery coho . . estimated to have spawned in natural habitat by basin; ( iv) the estimated percentage of hatchery coho% the total natural spawning population; and ( v) the mortality of naturally- spawning coho resulting from each fishery. NMFS may provide comments about hatchery prograk affecting coho to ODFW, with any concerns to be resolved between NMFS and ODFW. - - ( c) ln addition to recent modifications to hatchery practices and programs, a new vision is needed for how Oregon will utilize hatcheries in the best and most effective manner. Therefore, the ODFW and the OFWC shall engage in a process to create a strategic plan for fish hatcheries in Oregon over the next decade ( including state and federally- funded hatcheries, private hatcheries, and the STEP program). The essential elements of this process are as follows: ( i) Impartial analysis - conduct an impartial analysis of the scientific bases, and the social and economic effects of Oregon hatchery programs utilizing existing analyses and review where feasible, but conducting new analyses if necessary; ( ii) Review the Wild Fish Management Policy ( WFMP) - because the future plan for hatcheries in Oregon is dependent on implementation of the WFMP, ODFW shall conduct a science and stakeholder review to determine if this significant policy should be revised and shall make any revision by July 2000; ( iii) Frame alternative strategies -- convene a group of stockholders to . frame alternative strategies, including outcomes and descriptions, of how hatcheries will be used in Oregon over the next decade ( these strategies will address the use of hatcheries for wild fish population recovery including supplementation, research and monitoring, public education, and sport and commercial fishing opportunities); ( iv) Public review and selection of a strategy -- the OFWC shall, after public review and ' ;-'-!&%; f$'. i comment, adopt a strategic plan to guide development of future hatchery programs, incorporating the strategy developed and adopted in accordance with subpart ( iii) of this paragraph. ( d) Criteria and guidelines directing the design of projects that may affect fish passage have been established in a Memorandum of Understanding ( MOU) between the Oregon Department of Transportation ( ODOT), ODFW, the Oregon Department of Forestry ( ODF), the Oregon Department of Agriculture ( ODA), the Division of State Lands ( DSL) and the Federal Highway Administration. These guidelines apply to the design, construction and consultations of projects affecting fish passage. Under the MOU, projects requiring regulatory approvals that follow these criteria and guidelines are expedited. Oregon agencies will continue to provide technical assistance to ensure that the criteria and guidelines are applied appropriately in restoration projects, as well as any other projects that may affect fish passage through road crossings and similar structures. ODFW will work with state agencies, local governments, and watershed councils to ensure that Oregon's standards for fish passage set forth in Exhibit A to the MOU are understood and are implemented. - ( e) Fish presence, stream habitat, road and culvert surveys have been conducted for roads within ODOT jurisdiction and county roads in coastal basins, the Lower Columbia basin, the Willamette basin, and the Grande Ronbe/ lmnaha basins. Among the results of these surveys is the finding that culvert barriers to fish passage affect a substantial quantity of salmonid habitat. For example, surveys of county and state highways in western Oregon found over 1,200 culverts that are barriers to passage. As a result, ODOT is placing additional priority on restoring fish access. For 1998, ODOT repaired or replaced 35 culverts restoring access to 101 miles of salmonid habitat. For 1999, the Oregon Transportation Commission will be asked to fund approximately $ 4.0 million for culvert modification. ODOT and the Commission will continue to examine means to speed restoration of fish passage and to coordinate priorities with ODFW. ( f) Draft watershed assessment protocols have been developed and are being field tested. Beginning in 1999, SWCDs, watershed councils and others will be able to use the protocols as the basis for action plans to identify and prioritize opportunities to protect and restore salmonids. Watershed action plans have already been completed in a number of basins including the Rogue, Coos, Coquille and Grande Ronde. State agencies will work to support these watershed assessments and plans to the maximum extent practicable. Where watershed action plans have been developed under the protocols, GWEB will ensure that projects funded through the Watershed Improvement Grant Fund are consistent with watershed action plans, and other state agencies will work with SWCDs and watershed councils to ensure that activities they authorize, fund or undertake are consistent with watershed action plans to the maximum extent practicable. ( g) The State of Oregon has developed interim aquatic habitat restoration and enhancement guidelines for 1998. State agencies involved with restoration activities ( ODFW, ODF, DSL, ODA, DEQ, and GWEB) will continue to develop and refine the interim guidelines for final publication in April 1999. The guidelines will be applied in restoration activities funded or authorized by state agencies. The purpose of ' the guidelines will be to define aquatic restoration and to identify and encourage aquatic habitat restoration techniques to restore salmonids. . . ( h) ODA and O ~ hFave each entered into a Memorandum of Understanding with the Oregon Department'of Environmental Quality relating to the development of . Total Maximum Daily Loads ( TMDLs) and Water Quality Management Area Plans ( WQMAPs). O Dw~ ill adopt. a nd implement WQMAPs ( through the Healthy Streams Partnership) and ODF , will review the adequacy of forest practices rules to meet water quality standards. ODF and ODA will evaluate the effectiveness of these measures in achieving water quality standards on a regular basis and implement any changes required to meet the standards. ( i) Agencies are implementing a coordinated monitoring program, as described in the Oregon Plan. This program includes technical support and standardized protocols for watershed councils, stream habitat surveys, forest practice effectiveness monitoring, water withdrawal monitoring, ambient water quality monitoring, and biotic index studies, as well as fish presence surveys and salmonid abundance and survival monitoring in selected subbasins. State agencies are also' working to coordinate monitoring efforts by state, federal, and local entities, including watershed councils. State agencies will work actively to ensure that the monitoring measures' in the Oregon Plan are continued. - .. ( j) GWEB has put into place new processes for identifying and coordinating the delivery of financial and technical assistance to individuals, agencies, watershed councils and soil and water conservation districts as they implement watershed ' restoration projects to improve water quality and restore aquatic resources. Over $ 25 ' million has been distributed for watershed restoration projects in the last ten years. During the present ( 1 997- 99 biennium) GWEB has awarded over $ 1 2 million dollars in f- state and federal funds for technical'assistance and watershed restoration activities to implement the Oregon Plan. GWEB and state agencies will continue to seek financial resources to be allocated by GWEB for watershed restoration activities at the local and. statewide levels. ( k) State agencies will continue to encourage, support and work to provide incentives for local, tribal, and private . efforts to implement the Oregon Plan. In addition, state agencies will continue to provide financial assistance to local entities for projects to protect and restore salmonids to the extent consistent with their budgetary and legal authorities, and consistent with their work programs in the Oregon Plan. To the. maximum extent practicable, state agencies will also provide technical assistance and planning tools to provide local conservation groups to assist in and target watershed restoration efforts. These efforts ( during 1996 and 1997) are reported in " The Oregon. Plan for Salmon and Watersheds: Watershed Restoration Inventory, 1998." ~ u s c afe w of the important efforts that have been completed include: ( A) Eighty- two watershed councils have joined with forty- five Soil and Water Conservation Districts as well as private and public landowners to implement on- the- ground projects' to protect and restore salmonids. During 1996 and 1997, a reported $ 27.4 million was spent on 1,234 watershed restoration projects on non-federal lands. Both the amount spent and the number of projects represent significant increases ( of over 300 percent) over prior years. In 1996- 97, watershed councils, SWCDs and other organizations and individuals completed: ( i) 138 stream fencing projects, involving at least 301 miles of streambank; ( ii) 196 riparian area planting projects, involving at least 11 1 miles of streams; and ( iii) 458 instream habitat improvement projects. . . . ( B) Private and state forest landowners are implementing key efforts under the Oregon Plan, including the road risk and remediation program ( ODF- 1 and 2). Under this effort in 1996 and 1997, close to 4,000 miles of roads'have been surveyed to identify risks that the roads may pose to salmonid habitat. As the risks are identified, they are then prioritized for remediation following an established. protocol. Already, 52 miles of forest roads have been closed, 843 miles of road repair and reconstruction projects to - protect salmonid habitat have been completed, and an additional 14 miles of roads have been decommissioned or relocated.. In addition, 530 culverts have been replaced, upgraded or installed for fish passage purposes, improving access to a reported 146 stream miles. ( C) Organizations working in Tillamook County have developed the I ." J aw#~ t Tillamook County Performance Partnership. The Partnership is implementing the \*. Tillamook Bay National Estuary Program by addressing water quality, fisheries, floodplain management and economic development in the county. Among the actions that the Partnership has already accomplished are: ( i) the closure of seven miles of degraded forest roads and the rehabilitation of 469 miles of roads to meet current standards, at a cost of $ 1 8 million; ( ii) the fencing of 53 miles of streambank, and the construction of three cattle bridges and 100 alternative cattle watering sites, at a cost of $ 214,000; and ( iii) the completion of 24 instream restoration projects and 34 barbs protecting 4,200 feet of streambank, at a cost of $ 1.3 million dollars. ( D) The Confederated Tribes of the Grande Ronde Community of Oregon have completed a forest management plan that establishes standards for the protection of aquatic resources that are comparable to those found in the Aquatic Conservation Strategy ' of the Northwest Forest Plan. . % ( E) A combination of funding from the Oregon Wildlife Heritage Foundation and the National Fish and Wildlife Heritage Foundation ( private, non- profit organizations) is provi, ding support for seven biologists to design restoration projects. These projects are prioritized based on stream surveys, and are carried out with the voluntary participation and support of landowners. A ten- year monitoring plan has been funded- and implemented to determine project effectiveness: ( F) The Oregon Cattlemen's Association has implemented its WESt Program that is designed to help landowners better understand their watersheds and stream functions through assessments and monitoring. h he WESt Program brings landowners together along stream reaches, and offers a series of workshops, conducted on a site specific basis, free of charge. The workshops include riparian ecology, setting goals and objectives, Proper Functioning Condition ( PFC), data. collection and monitoring. Over 25 workshops have been held, with attendance ranging from 5 to 30 landowners per workshop. The WESt Program is sponsored by the Oregon Cattlemen's Association, DEQ, Oregon State University, and GWEB. ( G) Within the Tillamook State Forest road network 1,902 culverts have been replaced or added to'improve road drainage and to disconnect storm water runoff from roads reducing stream sediment impacts. Additionally, some of these culverts also improved fish passage at stream crossings. In this process, ODF has also replaced six culverts with bridges improving fish passage to approximately four miles of stream. The Tillamook State Foresl in conjunction with many partners, such F-as the Association of Northwest Steelheaders, G W EB, Simpson Timber Company, Tillamook County, the FishAmerica Foundation, Hardrock Construction Company, the Oregon Wildlife Heritage Foundation, the F& WS, the Oregon Youth Conservation Corps, Columbia Helicopters and Terra Helicopters, has also recently completed instream placement of over 400 rootwads, trees and boulders at a cost of $ 300,000 for habitat enhancement. ( 3) Key Agency Efforts. Continuation and completion of the following state agency efforts is critical to the success of the Oregon Plan. State agencies will make continuation or completion ( as appropriate) of the following efforts a high priority. ( a) The State of Oregon and the US. Department of Agriculture have entered into a Conservation Reserve Enhancement Program ( CREP). This cost- share program, one of the first of its kind, . will be used to reduce the impacts of agricultural practices through water quality. add habitat improvement. The objectives of the CREP are to: ( i) provide incentives'for farmers and ranchers to establish riparian buffers; ( ii) protect - . and restore at least 4,000 miles of stream habitat by providing up to 95,000 acres of riparian buffeis; ( i4) restore up to 5,000 acres of wetlands that will benefit salmonids; and ( iv) provide a mechanism for farmers and ranchers to comply with Oregon's ,- Senate Bill 101 0 ( 1 993 Or. Laws, ch. 263). ( b) ODF will work with non- industrial forest landowners to'administer the Stewardship Incentive Program and the Forest Resources Trust programs to protect and restore riparian and wetland areas that benefit salmonids. ( c) The Oregon Board of Forestry will determine, with the assistance of an advisory committee, to what extent changes to forest practices are needed to meet state water quality standards and to protect and restore salmonids. A substantial body of information regarding the effectiveness of current practices is being . developed. This information includes: ( i) the IMST report regarding . the role of forest practices and forest habitat in protecting and restoring salmonids; and ( ii) a series of - monitoring projects that include the Storms of 1996 study, a riparian areas study, a stream temperature study, and a road drainage study. Using this information, as well as other available scientific information including scientific information from NMFS, the advisory committee will make recommendations to the Board at both site and watershed scales on threats to salmonid habitat relating to sediment, water temperature, freshwater habitat needs, roads and fish passage. Based on the advisory committee's recommendations and other scientific information, the Board will make every effort to make its determinations by June 1999. The Board may . . determine that the most effective means of achieving any necessary changes to . - d;.~ .;* i;. z . I:@;.. %- .~ + k forest practices is through regulatory changes, statutory changes or through other programs . including programs to create incentives for forest landowners. In the event that the Board determines that legislative changes. are necessary to carry out its determinations, the Board will transmit any recommendations for such changes to the . Governor and to the Joint Committee at the earliest possible date. ( d) Consistent with administrative rule, and statutory and constitutional mandates for the management of state forests, ODF State Forest management plans will include an aquatic conservation strategy that has a high likelihood of protecting and restoring properly functioning aquatic habitat for salmonids on state forest lands. ( e) ODF will present to NMFS a Habitat Conservation Plan ( HCP) under Section 10 of the federal ESA that includes the Clatsop and Tillamook State Forests. ODF has already completed scierkific review and has public review underway for this draft HCP. The scientific and public review comments will be considered by ODF in . . completing the draft HCP. The draft HCP will be presented to NMFS by June 1999. An HCP for the ~ jliotSt tate Forest was approved by the US. Fish & Wildlife Service in 1995. In October af 1997, ODF and DSL forwarded the Elliott State Forest HCP to NMFS with the request that it be reviewed to determine whether it has a high likelihood of protecting and restoring properly functioning aquatic habitat conditions on state forest lands necessary to protect and restore salmonids. Based on discussions surrounding the NMFS review, ODF and DSL will determine what revisions, if any, are required to the Elliott HCP and/ or Forest Management Plan to ensure a high likelihood of protecting and restoring properly functioning aquatic habitat for salmonids. ( f) Before the OFWC adopts and implements fishery regulations that may result in taking of coho, ODFW will provide NMFS with'all available scientific information and analyses pertinent to the proposed regulation where the harvest measures are not under the jurisdiction of the PFMC, including results of the Oregon Plan monitoring and evaluation program. This information, together with the proposed regulation and supporting analysis, will be provided at least two weeks prior to the OFWC's action, to give NMFS time to review and comment on the proposed regulations. ( g) ODFW will evaluate the effects of predation on salmonids, and . will . work with . affected federal agencies to determine whether changes to programs and law relating to predation are warranted in order to protect and restore salmonids. P ( h) Under Oregon Senate Bill 101 0 ( 1 993 Or. Laws, ch. 2631, ODA will adopt Agricultural Water Qualify Management Area Plans ( AWQMAPs) for Tier I and Tier ll watersheds by the end of 2002. The AWQMAPs will be designed and implemented to meet load allocations for agriculture needed to achieve state water quality . . standards. In addition, ODA will work with ODFW, DEQ, GWEB, SWCDs, federal . agencies and watershed councils to determine to what extent additional measures related to achieving properly functioning riparian and aquatic habitat on agricultural lands are needed to protect and restore salmonids, giving attention first to priority areas identified in. the Oregon Plan. In the event ODA is unable to reach a consensus regarding such measures, ODA will ask the IMST to review areas of substantive ' scientific disagreement and to'make recommendations to ODA regarding how they should be resolved. In the event that legislative changes are needed to implement such measures, ODA will transmit any recommendations for such changes to. the Governor and to the Joint Committee at the earliest possible date. In addition, any measures identified as rieeded by ODA will be implemented at the earliest practicable time. * . ( i) ODFW will expedite its applications for instream water rights and OWRD will process such applications promptly where flow deficits are identified as adversely affecting salmonids, and where such rights. are not already in place. The Oregon - water Resources Department ( OWRD) and the Oregon Water Resources Commission ( OWRC) will- also seek to facilitate flow restoration targeted to streams identified by OWRD and ODFW as posing the most critical low- flow barriers to salmonids. In addition, where necessary, OWRD will continue to work with the Oregon State Police to provide enforcement of water use. Where illegal water uses are identified, OWRD will ensure outcomes consistent with maintenance and restoration of flows. ( j) The Oregon Environmental Quality commission ( EQC). and DEQ will evaluate and will make every effort to utilize their authorities to continue to provide additional protection to . priority areas ( as determined under section 1 ( f) of this Executive Order), including in- stream flow protection under state law, and antidegradation policy under . the federal Clean Water Act ( including Outstanding Resource Waters designations . and high quality waters designations). . ( k) DSL has proposed to adopt changes to its Essential Salmonid Habitat rules that will provide additional protection for spawning and rearing areas of anadromous salmonids. In addition, ODFW and DSL will consult with the OWRC to determine where it is necessary to administratively close priority areas ( including ' work under General Authorizations) to fill and removal activities in order to protect salmonids. . . DSL, ODFW, ODF and ODA also will work together to identify means of regulating the . uy- w :.-:: st. removal of organic material ( such as large woody debris) from streams where such removal would adversely affect salmonids and would not be contrary to other agency mandates. ( I) DSL will seek the advice of the IMST regarding whether gravel removal affects gravel and/ or sediment budgets in a manner that adversely affects salmonids. ( m) The Department of Land Conservation and ~ e v e l o p r n e n t ' ( ~ ~ acn~ d ) th, e Land Conservation- and Development Commission ( LCDC) will evaluate and, to the extent feasible, speed implementation of existing Goal 5 requirements for riparian corridors. ( n) DLCD, DEQ, ODF, ODA, ODFW, and DSL and their respective boards and commissions will evaluate and implement programs to protect and restore riparian vegetation for the purposes of achieving statewide water quality standards and . . protecting and restoring a aquatic habitat for salmonids. ' ( 0) DLCD, with, the assistance of DSL and ODFW, and in consultation with coastal cities and counties, shall review the requirements of Statewide Planning Goal i 6 as they pertain to estuarine resources important to the restoration of salmonids, and shall, report its findings to LCDC for its consideration. ( p) The Oregon State Police will work to facilitate the existing cooperative relationship with the NMFS Office of ~ a Ewnfo rcement, as well as tomaintain cooperation with other enforcement entities, in order to enhance law enforcement, public awareness and voluntary compliance related to harvest, habitat and other issues addressed in the Oregon Plan. ( q) The Oregon Parks and Recreation Department will continue to work to p. rovide information and education to the public on salmon and steelhead needs through park programs and interpretive aids. ( r) The Oregon Marine Board will work to ensure fish friendly boating and to develop boating facilities that protect salmonids. ( s) State natural resource agencies will continue, to the extent feasible, to support watershed councils by providing technical assistance to develop watershed assessments, restoration plans and to develop watershed priorities to benefit 7- salmonids. In addition, state natural resource agencies will work'on a larger . .:.... watershed scale to develop basin- wide restoration priorities. ( 4) Future Modifications; Public Involvement for the Oregon Plan Generally. The GNRO will solicit public co'mments and input from participants in the Oregon Plan regarding whether there are refinements or changes to the Plan and/ or the organizational framework for implementing the Plan that are necessary or desirable based on the experience gained over the past three years, or resulting from the widespread listings and proposed listings of salmon and trout under the federal ESA. Based on this public involvement, the GNRO will provide a report and recommendations to the Governor and the Joint Committee regarding whether modifications are necessary to the Oregon Plan in order to protect and restore coho and other salmonids. ( 5) Definitions. For purioses'of this Executive Order: . . ( aj The " Oregon Plan" means the Oregon Coastal Salmon Recovery lnitiative, dated March 1991, and the Steelhead. Supplement, dated January 1998. " Oregon Plan," as used in this Order, is intended to be consistent with the definition of the' Oregon Coastal Salmon Recovery lnitiative in Oregon Senate Bill 924 ( 1997 Or. Laws, .- cti. 7), and to include the Healthy Streams Partnership ( 1 993 Or. Laws, ch. 263). -. - ( b) " Protect" has the meaning given in section ( l)( d) of this Executive Order. ( c) " Restore" has the meaning'given in section ( l)( e) of this Executive Order. Restore necessarily includes actions to manage salmonids to provide for adequate escapement levels, and actions to increase the quantity and improve the quality of properly functioning habitat upon which salmonids depend. ( d) " Coho" means native wild coho salmon found in rivers and lakes along the Oregon Coast. ( el " Salmonids" means native wild salmon, char and trout in the State of Oregon. ( 6) Effective Date; Relation to Federal ESA. This Executive Order will take effect on the date that it is filed with the Secretary of State.

  	Citation × Citation Citation Abstract Copy Title: Recent paleolimnology of Upper Klamath Lake, Oregon Author: United States. Bureau of Reclamation Year: 2001, 2005 Recent Paleolimnology of Upper Klamath Lake Eilers et al. 2001 ABSTRACT Sediment cores were collected from Upper Klamath Lake in October, 1998 and analyzed for 210Pb, 14C, 15N, N, P, C, Ti, Al, diatoms, Pediastrum, and cyanobacterial akinetes. These results were used to reconstruct changes in water quality in Upper Klamath Lake over the last 150 years. The results showed that there was substantial mixing of the upper 10 cm of sediment, representing the previous 20 to 30 years. However, below that, 210Pb activity declined monotonically, allowing reasonable dating for the period from about 1850 to 1970. The sediment accumulation rates (SAR) showed a substantial increase in the 20th century. The increase in SAR corresponded with increases in erosional input from the watershed as represented by the increases in sediment concentrations of Ti and Al. The upper 20 cm of sediment (representing the last 150 years) also showed increases in C, N, P, and 15N. The increases in nutrient concentrations may be affected to various degrees by diagenetic reactions within the sediments, although the changes in concentrations also were marked by changes in the N:P ratio and in a qualitative change in the source of N as reflected in increasing S15N. The diatoms showed modest changes, particularly in the upper sediments, with increases in Asterionellaformosa, Stephanodiscus hantzschii, and S. parvus. Pediastrum, a green alga, was well-preserved in the sediments and exhibited a sharp decline in relative abundance in the upper sediments. Total cyanobacteria, as represented by preserved akinetes, exhibited only minor changes in the last 1000 years. However, a taxon which was formerly not present in the lake 150 years ago, Aphanizomenon, has shown major increases in recent decades. Although the mixing in the upper sediments prevents high-resolution temporal analysis of the recent history (e.g. last 30 years) of Upper Klamath Lake, the results demonstrate that major changes in water quality likely have occurred leading to a major modification of the phytoplankton assemblage. The changes in sediment composition are consistent with land use activities during this period that include substantial deforestation, drainage of wetlands, and agricultural activities associated with livestock and irrigated cropland.

Year: 2002, 2005 The controversial 2001 U.S. Fish and Wildlife Service water allocation decision in the Klamath Basin has been portrayed as an example of scientific guesswork operating under a flawed Endangered Species Act. This conclusion has been based on an interim National Research Council report, quickly prepared in late fall, 2001. We have reviewed several iterations of the NRC Interim Report as well as all Biological Opinions and management documents related to Klamath Basin suckers and provide an overview. The 2001 Biological Opinion and the Interim Report illustrate the lack of consensus typical of scientists in the early stages of exploring a complex system. Unfortunately, the decision created hardship for a small group of people and the lack of scientific consensus has politicized the debate. Politicians have assumed that the Interim Report has primacy in the scientific debate when, in fact, its speedy construction contributed to multiple errors that detract from its scientific usefulness. The NRC Interim Report has, instead, primarily served to deflect debate away from the needs of listed fishes to one about shortcomings in the Endangered Species Act. Although the process of science has been served by both the 2001 Biological Opinion and the Interim Report, both have shortcomings, and we see no justification for either side labeling the other's decisions or conclusions as "not sound science."

  	Citation × Citation Citation Abstract Copy Title: Recreational use and carrying capacity for the Klamath River Author: Shelby, Bo Year: 1984, 2005 ABSTRACT These reports document recreation use and estimate carrying capacities for the Klamath River in northern California. The river section studied runs from Interstate 5 near Yreka to the town of Orleans, and includes the lower sections of the Scott and Salmon River tributaries. A major highway runs along the river throughout the study area, with numerous; access points. The study covers the summer river running season and the fall salmon/ steel head fishing season. Because of the differences in time periods and activities, the study was done in two separate parts, each with a separate report. This document combines the two. The summer season report is presented first, followed by the fall season report. Each of these is preceeded by its own table of contents, list of tables, and summary of findings, and each is followed by its own appendices. The reports are separated by a colored page for easy reference. Data were collected by sampling, observation, and counting as well as a user questionnaire. Th? study presents a detailed description of river sections and documents recreational use by location and activity type. Carrying capacities are estimated for both river running and fishing activities. Estimates include discussions of ecological, facility, physical, and social carrying capacities, distinguishing descriptive and evaluative components. Limiting factors vary, depending on the activity and location. The more developed setting and the variety of activities and capacities distinguishes this project from earlier river capacity studies.

The Interior Columbia Basin Ecosystem Management Project: Scientific Assessment.) The Integrated Scientific Assessment for Ecosystem Management for the Interior Columbia Basin links landscape, aquatic, terrestrial, social, and economic characterizations to describe biophysical and social systems. Integration was achieved through a framework built around six goals for ecosystem management and three different views of the future. These goals are: maintain evolutionary and ecological processes; manage for multiple ecological domains and evolutionary timeframes; maintain viable populations of native and desired non-native species; encourage social and economic resiliency; manage for places with definable values; and, manage to maintain a variety of ecosystem goods, services, and conditions that society wants. Ratings of relative ecological integrity and socioeconomic resiliency were used to make broad statements about ecosystem conditions in the Basin. Currently in the Basin high integrity and resiliency are found on 16 and 20 percent of the area, respectively. Low integrity and resiliency are found on 60 and 68 percent of the area. Different approaches to management can alter the risks to the assets of people living in the Basin and to the ecosystem itself. Continuation of current management leads to increasing risks while management approaches focusing on reserves or restoration result in trends that mostly stabilize or reduce risks. Even where ecological integrity is projected to improve with the application of active management, population increases and the pressures of expanding demands on resources may cause increasing trends in risk.

Year: 2004, 2005 We monitored larval Lost River and shortnose suckers from natal beds in the Williamson and Sprague rivers to nursery grounds in Upper Klamath Lake. Downstream movements occurred at night, in the middle of the channel, and on the falling limb of the hydrograph. Ages, sizes, and developmental stages of larvae from spawning beds and the river mouth were similar, while larvae collected contemporaneously from the lake tended to be larger and better fed. Our results indicate in-river rearing was rare, that a rapid outmigration to the lake was favorable for larval survival, and that modification of the lower Williamson River does not appear to have prohibited rapid entry or preclude access to Upper Klamath Lake. Within the Williamson River and Upper Klamath Lake, emergent macrophytes supported significantly higher abundance, larger mean sizes, and better fed larvae than submerged macrophytes, woody vegetation, or open water areas. Analysis of seven years of larval sucker production and survival corroborated the habitat analysis by identifying a positive relationship with emergent macrophyte availability as well as a positive relationship with air temperature and a negative relationship with high wind. These findings illustrate the importance of fast growth, appropriate habitat and calm hydrological conditions for larvae, and are highly consistent with other larval fish studies.

  	Citation × Citation Citation Abstract Copy Title: Klamath River Basin issues and activities Author: Kyna Powers Year: 2005, 2008, 2006 Klamath River Basin Issues and Activities: An Overview Summary The Klamath River Basin, an area on the California-Oregon border, has become a focal point for local and national discussions on water management and water scarcity. Water and species management issues were brought to the forefront when severe drought in 2001 exacerbated competition for scarce water resources and generated conflict among several interests - farmers, Indian tribes, commercial and sport fishermen, other recreationists, federal wildlife refuge managers, environmental groups, and state, local, and tribal governments. The conflicts over water distribution and allocation are physically and legally complex, reflecting the varied and sometimes competing uses of limited water supplies in the Basin. For management purposes, the Basin is divided at Iron Gate Dam into the Upper and Lower Basins. As is true in many regions in the West, the federal government plays a prominent role in the Klamath Basin's water management. This role stems from three primary activities: (1) the operation and management of the Bureau of Reclamation's Klamath Water Project and Central Valley Project (e.g., Trinity River dams); (2) management of federal lands in the Basin, including five national wildlife refuges, several national forests, and public lands; and (3) implementation of federal laws, such as the Endangered Species Act (ESA), Clean Water Act (CWA), and National Environmental Policy Act (NEPA). Conflict was sparked in April of 2001 when the Bureau of Reclamation, which has supplied water to farms in the Upper Basin for nearly 100 years, announced that "no water [would] be available" for farms normally receiving water from the Upper Klamath Lake to avoid jeopardizing the existence of three fish species listed as endangered or threatened under the ESA. While some water was subsequently made available to some farmers from other sources (e.g., wells and other Bureau sources), many farmers faced serious hardships. During Reclamation's operations in September of 2002, warm water temperatures and atypically low flows in the lower Klamath contributed to the death of at least 33,000 adult salmonids. This die-off damaged fish stocks and the tribes, commercial fishermen, and recreational anglers that catch Klamath fish. There have been many studies, Biological Opinions, and operating plans over recent years, all of which have been controversial. The events of 2001 and 2002 prompted renewed efforts to resolve water conflicts in the Klamath Basin. Congress has responded to the controversy in a number of ways, including holding oversight hearings and appropriating funds for activities in the area. This report provides an overview of recent conflict in the Klamath Basin, with an emphasis on activities in the Upper Basin, and summarizes some of the activities taking place to improve water supply reliability and fish survival. This report will be updated as events warrant.

As is true in many regions in the West, the federal government plays a prominent role in the Klamath Basin's water management. This role stems from three primary activities: (1) the operation and management of the Bureau of Reclamation's Klamath Water Project and Central Valley Project (e.g., Trinity River dams); (2) management of federal lands in the Basin, including five national wildlife refuges, several national forests, and public lands; and (3) implementation of federal laws, such as the Endangered Species Act (ESA), Clean Water Act (CWA), and National Environmental Policy Act (NEPA). Conflict was sparked in April of 2001 when the Bureau of Reclamation, which has supplied water to farms in the Upper Basin for nearly 100 years, announced that "no water [would] be available" for farms normally receiving water from the Upper Klamath Lake to avoid jeopardizing the existence of three fish species listed as endangered or threatened under the ESA. While some water was subsequently made available to some farmers from other sources (e.g., wells and other Bureau sources), many farmers faced serious hardships. During Reclamation's operations in September of 2002, warm water temperatures and atypically low flows in the lower Klamath contributed to the death of at least 33,000 adult salmonids. This die-off damaged fish stocks and the tribes, commercial fishermen, and recreational anglers that catch Klamath fish. There have been many studies, Biological Opinions, and operating plans over recent years, all of which have been controversial. The events of 2001 and 2002 prompted renewed efforts to resolve water conflicts in the Klamath Basin. Congress has responded to the controversy in a number of ways, including holding oversight hearings and appropriating funds for activities in the area. This report provides an overview of recent conflict in the Klamath Basin, with an emphasis on activities in the Upper Basin, and summarizes some of the activities taking place to improve water supply reliability and fish survival. This report will be updated as events warrant. Close

West USDA-Forest Service, Klamath National Forest 1312 Fairlane Road, Yreka, CA 96097 ABSTRACT Ten instream fish habitat techniques were evaluated to determine which most effectively restored salmonid spawning and/or rearing conditions. Structure stability was estimated based on how intact each structure remained (by percent) and its age, we then projected useful life for each structure type. Cost in 1989 dollars was used to determine cost per unit habitat area provided. Observed use by spawners was used to estimate total number of redds per structure (over its life). Cost of providing spawning habitat (cost per redd) was calculated by dividing estimated total redds by structure cost. Habitats resulting from instream structures were classified using the modified Bisson method and we determined the influence zone of each structure using physical variables to define habitat area. Structures were biologically sampled using direct underwater observation techniques described by Hankin and Reeves1 (1989). Two person dive teams used a "two-pass" method to enumerate and classify salmonids by species and age-class (0+, 1+ or older juveniles, and adults), noting the presence of other species. Fish use of structure affected habitat (post-modification) was compared to use of habitats like those present prior to structure placement (pre-modification). Comparison of "pre-modification" and "post-modification" fish standing crops resulted in a "net fish difference" which was divided by structure cost, yielding "cost per fish reared11. Boulder weirs, the most expensive structures investigated, did not affect enough surface area to make cost per unit of affected habitat reasonable. Cabled cover logs and digger logs (lowest cost structures) were very cost effective at altering physical habitat condition. We believe cost of physically modifying habitat area is only one factor that is important enough to effect success or failure of a large scale habitat restoration program. Assuming all other factors are of equal weight, lowest cost structures can provide the "best value". Modification prescribed to restore stable spawning habitat needs close scrutiny. We believe it is essential to know how the existing habitat is used by spawners by conducting spawning area use surveys which identify redd location and quantify habitat available during each spawning period. Boulder deflectors were best utilized by Chinook salmon spawners, however chinook spawner use of "traditional" structures (weirs backfilled with gravel) was disappointing. Backfilling of instream structures with suitable gravel is a practice that should be discontinued. Steelhead spawner use of structures which result in "pocket water" type spawning areas were heavily used. This habitat configuration proved most desirable when woody object cover was readily available to the spawners. The highest steelhead spawner use was associated with boulder groups with wood and boulder/rootwad groups. We found rearing structures which provided high habitat and cover diversity received the best response from juvenile fish. We observed fish use over one summer and saw dramatic unpredictable use changes even through this short time period. Fish rearing needs during other seasons may differ substantially from summer needs, therefore, suitability of modified habitat probably also changes. Digger logs, one of the least costly and simplest structures, provided the best increase in fish standing crop (fish/m2) for the lowest cost. We believe digger logs were well used by rearing fish because they are one of the most natural restoration structures investigated. Other structures which were well used (small weirs, deflectors, and boulder groups with attached wood) also seem to closely duplicate naturally productive habitats. Higher velocity habitat types associated with boulder groups with wood, boulder rootwad groups, and boulder deflectors were selected by juvenile steelhead and chinook salmon. Providing overhead cover, especially if it extends into the water where it may also be used as object cover, seemed most valuable for juvenile steelhead and salmon if it was placed in a habitat type which would normally receive high fish use. Placement of object cover in slow velocity areas (pool and glide edges) had questionable value for summer rearing habitat restoration, however we do not know what value these structures may have during colder water high flow periods when fish seek slow velocity, densely-covered habitats. We defined the most cost effective method as one meeting restoration objectives, providing the greatest increase in fish use (per surface area or volume), over the longest time period, for the lowest cost. We rank structures evaluated in this study (from most cost-effective to least cost effective) as follows: Digger Logs, Boulder deflectors, Small Boulder Weirs, Boulder Groups with Woody Cover, Free Boulder Weirs, Large Boulder Weirs, Boulder Groups, Boulder/Rootwad Groups, Boulder/Rootwad Deflectors, Small Boulder Weirs, and Cabled Cover Logs.

The workshop was designed to review and discuss scientifically credible data and publications about 1) factors related to human activity that influence stream temperature and 2) behavioral, physical, and ecological mechanisms of cold water fish species for existing in streams with elevated temperatures. The goal of the workshop was to review empirical evidence and to identify points of agreement, disagreement, and knowledge gaps within the scientific community concerning the factors that influence stream temperature and fish responses to elevated temperatures. This information will assist the IMST in preparing a broader temperature report on Oregon's stream temperature water quality standards and their implementation. This report is prepared by the IMST. It was reviewed by workshop participants and revised by the IMST accordingly. The report includes abstracts of plenary presentations on factors that influence stream temperatures and fish responses, and the results of group discussions. The workshop participants focused on three main questions and were asked to list statements of agreement and disagreement, and to identify gaps in the scientific knowledge related to each question: ? How and where does riparian vegetation influence stream temperature? ? Do other changes in streams cause increases in stream temperature? ? How can apparently healthy fish populations exist in streams with temperatures higher than laboratory and field studies would indicate as healthy? The workshop participants provided answers to the questions in the form of bullets. The answers below represent the IMST's summation of the workshop findings and were reviewed by the participants. Several gaps in the scientific basis for specific questions or relationships were identified. The participants found no areas of disagreement for which technical information was available. They noted that any disagreements were not related to scientific interpretation, but were based on concerns or opinions about application, regulation, and management. How and where does riparian vegetation influence stream temperature? The influence of riparian vegetation on stream temperature is cumulative and complex, varying by site, over time, and across regions. Riparian vegetation can directly affect stream temperature by intercepting solar radiation and reducing stream heating. The influence of riparian shade in controlling temperature declines as streams widen in downstream reaches, but the role of riparian vegetation in providing water quality and fish habitat benefits continues to be important. Besides providing shade, riparian vegetation can also indirectly affect stream temperature by influencing microclimate, affecting channel morphology, affecting stream flow, influencing wind speed, affecting humidity, affecting soil temperature, using water, influencing air temperature, enhancing infiltration, and influencing thermal radiation. It is critical to know the site potential to understand what vegetation a site can support. There is not a good scientific understanding of how much vegetation shading is required to affect stream temperature. 1 This lack of understanding may be due to the spatial and temporal variability in landscape components, and the resulting variability in both the direct and indirect influences of vegetation on stream temperature. Therefore, it is difficult to generalize about the effects of vegetation on stream temperature. Do other changes in streams cause increases in stream temperature? The answer to this question is yes, other physical changes in the stream system can modify stream temperatures. Stream temperature is a product of complex interactions between geomorphology, soil, hydrology, vegetation, and climate within a watershed. Changes in these factors will result in changes in stream temperature. Human activities influence stream temperature by affecting one or more of four major components: riparian vegetation, channel morphology, hydrology, and surface/subsurface interactions. Stream systems vary substantially across the landscape, and site-specific information is critical to understanding stream temperature responses to human activities. How can apparently healthy fish populations exist in streams with temperatures higher than laboratory and field studies would indicate as healthy? Workshop participants identified several mechanisms that might explain the ability of fish populations to exist at higher than expected temperatures. The first mechanism was that the fish may have physiological adaptations to survive exposures to high temperatures. A second possibility was that stream habitats may contain cooler microhabitats that fish can occupy as refuge from higher temperatures. A third consideration is that ecological interactions may be different under differing thermal conditions resulting, for example, in changes in disease virulence or cumulative effects of stressors. Finally, since substantial differences exist between laboratory and field studies, it is difficult to apply results of laboratory studies to fish responses in the field. It is important to note that these proposed mechanisms are speculative and, as the list of gaps indicates, substantial experimental work is required to establish their influences on fish in different stream systems. Workshop Summaiy Workshop participants recognized gaps in the available science. Additional knowledge about human influences on stream temperatures and, consequently, influences on cold-water fish populations, will improve our ability to prevent further degradation of stream habitat and will enhance efforts geared towards the recovery of depressed fish populations. Even with these gaps, there was enough agreement on factors that influence stream temperature to indicate information is available to start developing and implementing management practices that are designed to reduce stream warming. It was suggested that managers should consider riparian vegetation, channel morphology, and hydrology, and should account for site differences.

Oregon has somewhere between eight and a dozen species of these primitive fishes. Their taxonomy is obscure because different species tend to look very similar through most of their life cycle, and they have not been well-studied in Oregon. Lampreys occur in the Columbia Basin, including the lower Snake River, along the Oregon coast, in the upper Klamath Basin, and in Goose Lake Basin in southeastern Oregon. They all begin life in fresh water where juveniles burrow into silt and filter feed on algae. As some species approach adulthood they migrate to the ocean or to lakes where they briefly become ecto-parasites, feeding on other live fishes by attaching to them with sucker disc mouths. Other species remain non-parasitic. In addition to some enigmatic species identities, we generally have very little information about the detailed distributions, life histories and basic biology of lampreys. Lampreys became a conservation concern in the early 1990s when tribal co-managers and some Oregon Department of Fish and Wildlife (ODFW) staff noted that populations of Pacific Lampreys, Lampetra tridentata, were apparently declining to perilously low numbers. Pacific Lampreys were listed as an Oregon State sensitive species in 1993 and were given further legal protected status by the state in 1997 (OAR 635-044-0130). Lamprey status is difficult to assess for several reasons: 1) Most observations of lampreys in fresh water are of juveniles and it is difficult to tell the various species apart, even to the extent that the various species are currently clearly designated; 2) Data on lamprey is only collected incidental to monitoring of salmonids. The design and efficiency of the data collection effort is not always adequate for lampreys; and 3) We have very few historic data sets for lampreys. Therefore we often cannot determine how the abundances and distributions we see now compare with those in the past. The limited data that we have suggests that lampreys have declined through many parts of their ranges. The most precipitous declines appear to be in the upper Columbia and Snake basins where we have some historic data from mainstem dam counts. Pacific Lampreys have declined to only about 200 adults annually passing the Snake River dams. We also have evidence of declines of Pacific Lampreys in the lower Columbia and on the Oregon coast, although our data is quite limited. We have little to no information about any of the other species of lampreys. We are not even sure whether some of the recognized species, like the River Lamprey (L. ayresi), is still present in Oregon. This paper concludes with a Problem Analysis for Oregon lampreys. Our biggest problem is poor information, ranging from not knowing basic species identity to having inefficient or no systematic monitoring of lamprey abundance and distribution. ODFW continued an annual harvest on Pacific Lamprey in the Willamette Basin in 2001, but we lack the necessary information to assess the affects of the harvest on the population. Major habitat problems that affect lampreys include upstream passage over artificial barriers, a need for lamprey-friendly screening of water diversions, and urban and agricultural development of low-gradient flood plain habitats.

Lynne (Mary Lynne), 1946-; Baldwin, Pamela Year: 2004, 2008, 2005 IB10072 08-26-04 Endangered Species: Difficult Choices SUMMARY The 108th Congress is considering various proposals to amend the Endangered Species Act of 1973 (ESA). Major issues in recent years have included changing the role of science in decision-making, changing the role of critical habitat, reducing conflicts with Department of Defense activities, incorporating further protection for property owners, and increasing protection of listed species, among others. In addition, many have advocated including significant changes to ESA regulations made during the Clinton Administration in the law itself. The ESA has been one of the more contentious environmental laws. This may stem from its strict substantive provisions, which can affect the use of both federal and non-federal lands and resources. Under the ESA, certain species of plants and animals (both vertebrate and invertebrate) are listed as "endangered" or "threatened" according to assessments of their risk of extinction. Once a species is listed, powerful legal tools are available to aid its recovery and protect its habitat. The ESA may also be controversial because dwindling species are usually harbingers of resource scarcity: the most common cause of listing species is habitat loss. Recent efforts in the House would modify ESA provisions that designate critical habitat, and that provide for scientific peer review. The authorization for spending under the ESA expired on October 1, 1992. The prohibitions and requirements of the ESA remain in force, even in the absence of an authorization, and funds have been appropriated to imple- ment the administrative provisions of the ESA in each subsequent fiscal year. In the 108th Congress, two bills (H.R. 1662 and H.R. 2933) have been reported that would, respectively, address issues concerning scientific peer review and critical habitat. These bills may be brought to the House floor in September. Earlier, P.L. 108-108 (Interior appropriations) provided $265 million for FY2004 for programs related to endangered species. P.L. 108-136 (Defense authorization) included an ESA amendment to direct that critical habitat not be designated on military lands under certain conditions when Integrated Natural Resources Management Plans are in effect. P.L. 108-137 (Energy and Water appropriations) prohibited use of FY2004 or earlier funds to reduce water deliveries under existing contracts for ESA compliance for the silvery minnow on the Middle Rio Grande River unless water is obtained from a willing seller or lessor. The act also established an executive committee to oversee the Collaborative Program associated with this situation. P.L. 108-148 (Healthy Forests Act) authorized hazardous fuels reduction projects on BLM and national forest lands including those containing listed species habitat; directed establishment of a healthy forests reserve program to promote recovery of listed species; and directed the Secretary of the Interior to provide assurances to landowners whose enrollment in the healthy forests reserve program results in new conservation benefits for ESA-listed species.

Recent efforts in the House would modify ESA provisions that designate critical habitat, and that provide for scientific peer review. The authorization for spending under the ESA expired on October 1, 1992. The prohibitions and requirements of the ESA remain in force, even in the absence of an authorization, and funds have been appropriated to imple- ment the administrative provisions of the ESA in each subsequent fiscal year. In the 108th Congress, two bills (H.R. 1662 and H.R. 2933) have been reported that would, respectively, address issues concerning scientific peer review and critical habitat. These bills may be brought to the House floor in September. Earlier, P.L. 108-108 (Interior appropriations) provided $265 million for FY2004 for programs related to endangered species. P.L. 108-136 (Defense authorization) included an ESA amendment to direct that critical habitat not be designated on military lands under certain conditions when Integrated Natural Resources Management Plans are in effect. P.L. 108-137 (Energy and Water appropriations) prohibited use of FY2004 or earlier funds to reduce water deliveries under existing contracts for ESA compliance for the silvery minnow on the Middle Rio Grande River unless water is obtained from a willing seller or lessor. The act also established an executive committee to oversee the Collaborative Program associated with this situation. P.L. 108-148 (Healthy Forests Act) authorized hazardous fuels reduction projects on BLM and national forest lands including those containing listed species habitat; directed establishment of a healthy forests reserve program to promote recovery of listed species; and directed the Secretary of the Interior to provide assurances to landowners whose enrollment in the healthy forests reserve program results in new conservation benefits for ESA-listed species.

The U.S. Fish and Wildlife Service, Coastal California Fish an - Wildlife Office (CCFWO) was funded through the Klamath River Fish and Wildlife Restoration Act (P. L.99-552) in the Fall of 1993-1996 to address this concern. The 1995 and 1996 survey season marked the third and fourth year that the CCFWO conducted investigations on the upper mainstem Klamath River to derive a reasonable estimate of natural * fall chinook spawners. A total of 339 redds were observed in the 1993 survey. In 1994 and 1995, redd counts increased to a total of 1,702 and 3,240 respectively. During the 1994 and 1995 spawning, seasons, there was evidence that unspawned surplus adult fall chinook salmon released from Iron Gate Hatchery (IGH) successfully spawned in the Klamath River. One hatchery fin clipped adult was observed spawning.30 miles downstream of the hatchery. In 1996, 1,372 redds were observed which wasa decrease of 43% from the previous year. There was complete retention of hatchery origin adults by IGH in 1996, although, the distribution of redds remained the same as previous years. With the new hatchery policy of excess return retention, mainstem escapement can now be considered a reasonable estimate of natural spawning adult chinook salmon. Reddsubstrate composition estimates remained consistent with previous spa- *:g survey data. Based upon 210 redd measurements from 1995-1996, the average redd size L ...e mainstem of the Klamath River was 9.6 nr. The average pit depth, mound depth, and adjacent depth for 1995-1996 was similar to previous survey results. Redds were most common along the wetted channel margins with numerous redds observed in side channels with suitable gravel and water velocities. Unlike 1993 and 1994 some redds were observed by 1995 and 1996 survey crews in rnid-channei areas. Recreational suction dredge mining was present throughout the survey from the confluence of Scott River downstream to the confluence of Indian Creek, although only two redds were observed on recent dredge tailings. Under the existing mining regulations, adverse impacts on redds could occur below the Scon River without protection of spawning areas.

Investigations began in October 1988, with this reporting period covering October 1991 through September 1992. Adult chinook spawner escapement was addressed by surveys of redds, live fish and carcasses, and by radioteleiretry. Spawner numbers were v?ry low, with only 22 redds observed in fall 1991/winter 1992. The peak count of adult Chinook was 97 fish in early November. Radiotelemetry of migrating spawners (n?8) was used to locate remote spawning areas. Emigrating juvenile Chinook salmon, steelhead trout 10. mvkissV/ coho salmon (fi. kisutchl. and coastal cutthroat trout (g. clarltiV were trapped at river kilometer (rkm) 3.35 with a rotary screw trap (screw trap). The trapping period extended from April to July for a total of 75 trapping nights. Screw trap catches totaled 10,688 chinook, 1,388 steelhead, 99 coho and 10 cutthroat. Peak Chinook emigration occurred during the week of May 17, which is consistent with the past 3 years of monitoring. A juvenile weir was operated 58 nights, and caught a total of 9,166 chinook, 1,196 steelhead, 127 coho and 1 cutthroat. The index of abundance for emigrating chinook during the 1992 juvenile trapping period was 49,590. Sixty-five percent of the juvenile chinook caught during the trapping season were marked with coded wire tags (n-12,687) and released back into Blue Creek at rkm 3.3. Mean water temperatures varied from 6.3 to 18.6 XI and stream flows ranged from 43 to 2178 eft (1.3 to 61.7 m3/?) during the Fiscal Year (FY) 1992 study season.

The objectives of the project include: ? Expanding hands-on field science watershed education. ? Encouraging a sense of resource stewardship among students at all grade levels. ? Collecting quality data for inclusion in the 319h data base. ? Teaching applications of the scientific method. ? Providing on-going inservice training for teachers to increase the effectiveness of the project. Project tasks that were completed include acquisition and analysis of Klamath River Watershed Data, including river water temperatures, river cross sectional profiles and spawning ground surveys. Descriptions of methodology are included in the report. Many other watershed-related projects were undertaken by schools. In some cases the field data was collected and compiled by agency personnel. The spawning ground survey data collected by student volunteers was part of a project conducted by the California Department of Fish and Game and the U.S. Forest Service. Although a substantial amount of excellent work has been accomplished by the schools, the opportunity exists to improve the program at all levels. Increased field and technical support is needed to successfully integrate the goals of the project. Computer training for teachers and students is an essential component of the project, which would allow analysis of data and creation of web sites within classrooms. Data analysis and reporting is the critical component of the project that would provide students with a complete understanding of scientific research methodology. Providing a forum for communication between the 319h participants is another important area of the project that needs to be expanded. Travel time, mountainous topography, and intense winter storms can be barriers to travel in Siskiyou County. Communication helps to increase the level of standardization of data collection and transfer and gives teachers a chance to share successful ideas. Communication also sustains the positive momentum of the project, reinforcing the idea of working as a team towards establishing common goals for watershed education.

Committee on Resources Year: 2005, 2007 I. Executive Summary There is increasing recognition from most quarters that the Endangered Species Act (ESA) needs to be improved. Exactly what those improvements should be is less uniform. This report examines the implementation of selected aspects of the endangered species program relying predominately on information provided by the primary implementing agencies, the United States Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) and offers some recommendations for possible improvements to the program. Debate over the ESA has traditionally been highly polarized. For example, compensating landowners for takings or reductions in property value has been opposed by some who argue updating the law to address this is not necessary. While consensus on other issues such as the need for increasing conservation incentives and the role states play in endangered species conservation has begun to emerge, one of the most debated aspects of ESA implementation continues to be whether the ESA is effectively conserving endangered and threatened species. While there have been significant strides in conserving individual species such as the whooping crane, red-cockaded woodpecker and gray wolf, few species have been delisted (removed from the endangered list) or downlisted (changed in status from endangered to threatened) because of successful ESA conservation efforts. Some argue that the number of recovered species is an unfair measure, asserting that the three decades the ESA has been in existence is an insufficient amount of time for the lengthy process of species recovery and point to listed species that have not gone extinct as evidence the ESA 'saves' species. From the opposing perspective, while recovery to the point of delisting may require a substantial amount of time for many species, after three decades more progress should be demonstrable through species that have recovered and been delisted. Even if a species has increased in numbers or distribution or the threats facing the species have been reduced, if it has not been delisted on the basis of recovery, the ESA's prohibitions and regulations remain applicable and the ESA should not be a 'one way street.' Of 40 total species removed from the list, 10 domestic species were delisted because of "recovery". Of 33 reclassified species, 10 domestic downlistings (a change from endangered to threatened status) reflected a reduced threat assessment which also allowed more flexibility in management. The FWS's most recent report to Congress (Fiscal years 2001-2002) shows that 77 percent of listed species fall in the 0 to 25 percent recovery achieved bracket and 2 percent fall in the 76 to 100 percent recovery achieved bracket. 39 percent of the FWS managed species are of uncertain status. Of those with an assessed trend, at one end of the spectrum are 3 percent possibly extinct, 1 percent occurring only in captivity and 21 percent declining and at the other end are 30 percent stable and 6 percent improving. These assessments however are subjective. Additionally, the assessment that a species is improving or stable may reflect, for example, a reduction in perceived threats or corrections to inaccurate threat assessments that stemmed from erroneous data rather than actual changes in species' trends that are demonstrated by improved numbers, distribution or other such measurements. Consequently, a meaningful assessment of conservation trends under the ESA using these data is not possible. The data used to list a number of species has been subsequently determined to be erroneous and species that likely do not merit classification as endangered or threatened remain listed. This can consume resources that could be directed to species that do merit listing. The assignment of recovery priorities appears highly skewed and the recovery priority for some species seems questionable. A meaningful distinction between endangered status and threatened status has been blurred as has been the framework for the mechanism of critical habitat. Expenditure reporting has improved but presents an incomplete picture of financial resources dedicated to endangered species. Workloads for litigation regarding activities such as consultation and listing under the ESA's complex structure compete for resources that could otherwise be directed at recovery efforts. The demands associated with ESA Section 4 determinations in combination with the pace of species listings and delistings, the number of possible future additions to the list and the economic impact of listings likely indicate that the current program is not sustainable.

G Year: 2001, 2007, 2005 ABSTRACT A water quality study was performed in the mainstem Klamath River from Keno, Oregon to Seiad Valley, California during 1996 through 1998. Four sites within the study area were continuously monitored using multiparameter recorders. Water quality sampling was also performed at these four locations in 1996 and 1997. Additional water quality sampling sites were added in 1998 for a total of 8 locations between Keno and Seiad. Temperature ranged from near zero ?C to >25 ?C with cooler temperatures in early spring and fall, and maximum temperatures occurring in July and August of each year. Dissolved oxygen concentration ranged from near zero mg/L to >13 mg/L with highest DO occurring in early spring and fall and lowest DO occurring in mid-summer. Air temperature was generally highly correlated with water temperature with r values ranging from 0.8 to 0.9 during the study period from 1996-1998. Water temperature in the study area exceeded chronic (>16?C) and acute (>22?C) criteria for salmonids during the summer months.

Title: Water quality and nutrient loading in the Klamath River between Keno, Oregon and Seiad Valley, California from 1996-1998 Author: Campbell, S. G Year: 2001, 2007, 2005 ABSTRACT A water quality study was performed in the mainstem Klamath River from Keno, Oregon to Seiad Valley, California during 1996 through 1998. Four sites within the study area were continuously monitored using multiparameter recorders. Water quality sampling was also performed at these four locations in 1996 and 1997. Additional water quality sampling sites were added in 1998 for a total of 8 locations between Keno and Seiad. Temperature ranged from near zero ?C to >25 ?C with cooler temperatures in early spring and fall, and maximum temperatures occurring in July and August of each year. Dissolved oxygen concentration ranged from near zero mg/L to >13 mg/L with highest DO occurring in early spring and fall and lowest DO occurring in mid-summer. Air temperature was generally highly correlated with water temperature with r values ranging from 0.8 to 0.9 during the study period from 1996-1998. Water temperature in the study area exceeded chronic (>16?C) and acute (>22?C) criteria for salmonids during the summer months. Although chronic DO (<7 mg/L) criteria were exceeded throughout most of the study area during the summer, in the free-flowing river below Iron Gate Dam the acute DO (<5.5 mg/L) criteria were not exceeded.

  	Citation × Citation Citation Abstract Copy Title: Lower Klamath River instream flow study : scoping evaluation for the Yurok Indian Reservation Author: Anglin, Donald R Year: 1994, 2007, 2006 ABSTRACT The U.S. Fish and Wildlife Service, Lower Columbia River Fishery Resource Office was funded by Bureau of Indian Affairs to conduct an instream flow assessment for the lower Klamath River within the Yurok Indian Reservation in northern California using the Instream Flow Incremental Methodology (IFIM). Specific study tasks consisted of developing an explicit statement of purpose, definition of the study area and target species, assembly and evaluation of hydrologic, water quality, and physical data as well as biological and fish habitat information. A reconnaissance survey of the proposed study area was also conducted. The purpose for conducting the proposed flow study was the Yurok Tribe's desire to protect the Klamath basin water supply for the production of anadromous fish. The ultimate goal was to protect, restore, and enhance the anadromous fishery resources on the Reservation and in the basin as a whole. The study area was defined as the lower Klamath River and tributaries from the confluence with the Trinity River downstream to the area of tidal influence. Although the mainstem Klamath only was proposed for flow studies, the tributaries were included in the study area as a result of their hydrologic and biological relevance. Target species were identified as chinook salmon {Oncorhynchus tshawytscha), coho salmon (0. kisutch), steelhead trout (0. mykiss) , green sturgeon {Acipenser medirostris) , eulachon (Thaleichthys pacificus) , and Pacific lamprey (Lampetra tridentata) . Assembly and evaluation of relevant information was accomplished from results of a public scoping meeting and the review of a large volume of both published and file reports as well as numerous personal communications. Hydrology of the lower Klamath River is affected by U.S. Bureau of Reclamation projects in both the upper Klamath and upper Trinity subbasins. Several hydroelectric projects in the upper Klamath subbasin affect flow patterns, and agricultural activities in the upper Klamath subbasin and tributaries and the Central Valley Project in the upper Trinity subbasin have reduced water yield from the basin. Water quality concerns were identified as elevated water temperatures and nutrient levels resulting from land use activities throughout the basin. Hydrologic and water quality impacts are partially mitigated in the lower Klamath by tributary inflow throughout the basin. The physical environment in the basin has been altered by land use practices and several major flood events. Alterations include loss of riparian vegetation and stream channel stability, loss of soil moisture storage capacity and infiltration potential, debris slides and logjams resulting in migration barriers, reduced supply of large woody debris for recruitment into the stream channel, and sedimentation of spawning and rearing habitat. Fish habitat in most lower Klamath tributaries has been surveyed and deficiencies as well as good quality habitat have been described. Significant production potential exists in most tributaries, however much restoration work needs to be completed to realize the potential. Habitat characteristics for the mainstem Klamath have not been described. Life history and production data are presented for target species and a brief review of sources for suitability criteria is presented. Harvest management and escapement for naturally spawning fall chinook salmon were reviewed from 1978 through 1993. Escapement has varied over the years but a general downward trend in naturally spawning fall chinook can be observed, particularly in recent years. Escapement goals for the Klamath basin varied from 115,000 in 1978 to an "emergency" floor of 27,000 in 1992. Actual escapement of naturally spawning adult fall chinook varied from a high of 113,000 in 1986 to a low of 11,600 in 1991. Escapement in 1978 totalled 58,500 and preliminary estimates of escapement in 1993 were 21,000 naturally spawning adults. Factors affecting production and subsequent stock size and escapement included variable ocean survival, degraded freshwater habitat conditions, the recent six-year drought, releases of large numbers of hatchery juveniles, and harvest management methodologies that have failed to adequately match harvest to predicted stock size. Differential harvest rates for Klamath and Trinity subbasin fall chinook have also complicated attempts to structure the harvest. Field reconnaisance surveys were conducted in spring and summer 1993 for the proposed mainstem Klamath study area. Two distinct river segments were identified based on macrohabitat characteristics. Microhabitat was classified within each river segment and mapped on USGS quadrangle maps. Cross section identification was postponed pending the decision to move forward with the flow study. Following the scoping tasks described above, conclusions and recommendations were developed. No information was reviewed that indicated the need for an instream flow study in the lower Klamath River. The two basic problems affecting anadromous fish production are degraded freshwater habitat and chronic underescapement. Coordination and planning for instream flow studies on a basin-wide scale was recommended. Biological data gaps were identified which need to be addressed before an instream flow study can be completed for the lower Klamath. Suitability criteria for habitat analysis also need to be identified. Habitat restoration and protection and proper management of anadromous fishery resources were identified as the highest priorities to begin restoration of anadromous stocks. Specific recommendations for habitat restoration included watershed and riparian zone restoration, barrier removal, instream habitat inventory, restoration, and monitoring, estuary studies, and description of streamflow characteristics for lower Klamath tributaries. Recommended fishery resource studies included collection of basic life history data, monitoring for adult escapement and juvenile production, description of estuary usage, effects of hatchery programs on both adult and juvenile wild fish, evaluation of the accelerated stocking program, and refinement of harvest management methodologies to achieve appropriate escapement of naturally spawning stocks into all subbasins.

  	Citation × Citation Citation Abstract Copy Title: Biological assessment of the Klamath Project's continuing operations on southern Oregon/Northern California esu coho salmon and critical habitat for southern Oregon/northern California esu coho salmon Year: 2001, 2004 The Bureau of Reclamation (Reclamation) is the responsible Federal agency for operation of the Klamath Project (Project). Operation of the Project has been the subject of numerous previous consultations with the U.S. Fish and Wildlife Service (Service) and one with the National Marine Fisheries Service (NMFS) under Section 7 of the Endangered Species Act (ESA). Severe drought conditions in 1992 and 1994 and resultant associated shortages in project water supplies coupled with the 1997 listing of the southern Oregon/northern California (SONCC) coho salmon, Oncorhynchus kisutch, as threatened in the Klamath River downstream from the Project led to a review of Reclamation 19s operations. This biological assessment (BA) describes the effects on federally-listed species (i.e., coho salmon) and its designated critical habitat from on-going operation of the project based on historic operations, as described in this BA. The biological opinion (BO) addressing this BA and any subsequent BA amendments will be among the information that will inform the development of alternatives of the long-term operations plan and environmental impact statement (EIS). Reclamation is developing a long-term operations plan and EIS for the Project. The preferred alternative for implementation from the long-term operations plan would be the subject of a separate future ESA consultation. This BA describes the needs of anadromous fish with emphasis on SONCC coho salmon. It was developed using the best available scientific and commercial information on anadromous fish in the Klamath River. Coho salmon were listed as threatened on June 6, 1997 (NMFS 1997). The NMFS published a final rule designating critical habitat for SONCC coho salmon in May, 1999 (NMFS 1999a). Designated critical habitat for SONCC coho salmon encompasses accessible reaches of all rivers (including estuarine areas and tributaries) between the Mattole River in California and the Elk River in Oregon. Critical habitat includes all waterways, substrate, and adjacent riparian zones below longstanding, naturally impassable barriers. The areas upstream from Iron Gate Dam (IGD) (river mile 190) were not proposed critical habitat because areas downstream were considered sufficient for the conservation of the species. Reclamation has not evaluated whether the action that is the subject of this BA is consistent with its trust responsibility to Klamath Basin Indian Tribes. There are several important scientific reports and analyses (e.g., Phase II flow study) currently not available to Reclamation concerning threatened coho salmon, their habitat, and water quality as it relates to appropriate river flows that may be necessary to operate the Project consistent with the trust responsibility to Klamath Basin Indian Tribes. When this additional information becomes available, Reclamation intends to consider it during the development of the Project operations plans and include it in subsequent consultations with NMFS, as appropriate.

Fish and Wildlife Service, Klamath Basin National Wildlife Refuge, Route 1, Box 74, Tulelake, CA 96134 Introduction The Lost River ( Deltistes luxatus) and shortnose ( Chasmistes brevirostris) suckers were federally listed as endangered species on July 18, 1988 ( Federal Register 53: 27130- 27134). Both sucker species are relatively long- lived, have a limited geographic range, and are endemic to the Upper Klamath Basin of Northern California and Southern Oregon. Habitat degradation from water diversions and loss of riparian and wetlands habitats associated with agricultural development within their historic range is believed to be the major reason for the species decline ( U. S. Fish and Wildlife Service 1993). A more detailed description on the life history, habitat requirements, and causes of decline of the species can be found in the Lost River and Shortnose Sucker Recovery Plan ( U. S. Fish and Wildlife Service 1993). Tule Lake National Wildlife Refuge ( NWR), established in 1928, consists of 2 return flow sumps ( Sump 1( A) and 1( B)) totaling 13,000 acres surrounded by 17,000 acres of intensively farmed lands ( Fig. 1). The refuge and surrounding private agricultural lands occupy the historic lake bed of Tule Lake, a 95,000 acre lake and marsh area that was reclaimed in the early 1900fs as part of the Klamath Reclamation Project. Current management of the refuge is directed by the Kuchel Act of 1964 which mandates the refuge be managed for the major purpose of waterfowl management but with optimal agricultural use that is consistent therewith. Both sumps are shallow ( 0.1 - 2.0 m) and consist of approximately 10,500 acres of open water with a 2,500 acre shallow (< 0.1 m) emergent marsh at the northeast corner of Sump 1( A). Tule Lake has been identified as a potential refugia for both sucker species ( U. S. Fish and Wildlife Service 1993). Tule T like National Wildlife Sump 3 Lease lands Field . Station Cocbetative Fanning Fields Area J Lease Lands Sump 2 I ease I , ands Figure 1. Tule Lake National Wildlife Refuge, California. During winter, water within the sumps is comprised primarily of local runoff and during summer water is comprised primarily of irrigation return flows, originating from Upper Klamath Lake. Summer water quality in the sumps is similar to other water bodies within the Upper Klamath Basin and is considered hypereutrophic ( Dileanis et al. 1996). Water quality problems include low dissolved oxygen ( DO) and high hydrogen ion concentrations ( pH) and unionized ammonia. Water quality in the Tule Lake sumps is directly affected by hypereutrophic conditions in Upper Klamath Lake ( U. S. Fish and Wildlife Service 1993). Studies conducted after publication of the Shortnose and Lost River Sucker Recovery Plan indicate that Tule Lake contains an estimated 159 ( 95% CI = 48- 289) shortnose and 105 ( 95% CI = 25- 175) Lost River suckers ( Scoppetone and Buettner 1995). Confidence intervals for these estimates are large because of small sample sizes and low rates of recapture. Recruitment rates for the Tule Lake population via spawning below Anderson- Rose Dam is low with significant larval production occurring only in 1995 ( monitoring occurred 1991- 99) ( M. Buettner, pers. comm). Entrainment from the irrigation system is likely the largest source offish for Tule Lake ( U. S. Bureau of Reclamation 1998). Both species of suckers in Tule lake are in good physical condition relative to fish in Clear Lake and Upper Klamath Lake with Tule Lake fish being generally heavier and exhibiting few if any problems with parasites or lamprey. ( Scoppetone and Buettner 1995). U. S. Bureau of Reclamation ( Reclamation) biologists tracked 10 radio- marked suckers in Tule Lake from 1993- 95. From these studies, specific use areas by time period were identified with over 99% of radio locations occurring in Sump 1( A). Of particular importance from these studies was identification of an over- summer site in the south central region of Sump 1( A) termed the ADonut Hole# ( DH). In early 1999, the U. S. Fish and Wildlife Service ( Service) proposed a wetland enhancement project on the 3,500 acre Sump 1( B). The project was designed to improve habitat for waterfowl and other associated wetland species as well as improve water quality through the conversion of Sump 1( B) from an open body of shallow water to an emergent year- round flooded wetland. The primary mechanism to create the desired habitat condition is a series of annual spring/ summer drawdowns thereby creating conditions suitable for germination of desired emergent plant species. Of principal concern in developing the project was the potential effects on suckers within the sumps. Because of the proximity of both sucker species in adjacent Sump 1( A), a project monitoring plan was developed to ascertain the potential effects of the Sump 1( B) Project on suckers and water quality. Our monitoring design benefitted from studies of water quality and sucker movements by Reclamation biologists from 1992- 95. This report summarizes findings of the first year= s pre- project monitoring effort ( April- December, 1999) relative to water quality and movements of radio- marked suckers. Objectives 1. Describe seasonal distribution and movement patterns of both sucker species in Tule Lake NWR and determine if fish movements have changed since initial studies by Reclamation biologists in 1993- 95. 2. Characterize water quality, in space and time, of areas used by adult suckers compared to areas which are not used. 3. Document and describe movements of radio- marked suckers to spawning areas below Anderson- Rose dam. 4. Determine whether recruitment of larvae and juvenile was occurring below Anderson- Rose Dam. Methods Monitoring radio- marked adult suckers In April and May, 1999, Reclamation biologists captured 14 suckers and surgically implanted radio- transmitters ( ATS, Isanti, MN) having a projected battery life of 12 months. Each transmitter had an external antennae that exited the body cavity near the lateral line of the fish. Eleven Lost River and 3 shortnose suckers were captured using trammel nets at the northwest corner of Sump 1( A) ( 9 fish) and immediately downstream of Anderson- Rose Dam on the Lost River ( 5 fish) ( Table 1). We located radio- marked fish via air thrust boats using a scanning receiver and 4- element yagi antennae. Fish were located fish 4 times/ month during March and April, 2 times/ month from May through September, and once per month from October through December. Fish not located via boat were located from fixed wing aircraft. We determined fish locations by moving as close as possible to undisturbed fish and recording locations with a Global Positioning System ( GPS). All GPS positions consisted of 180 rover points/ location and were differentially corrected via post processing software ( PFinder ver. 2.11). We recorded depth information at each fish location. To determine timing and duration of the spawning migration, we monitored radio-marked fish from vehicles on the east levee of the Lost River downstream of Anderson- Rose Dam. Table 1.

Egg viability surveys were conducted in the gravel sediments immediately below the dam in May. Water quality We preselected water quality sampling sites ( Fig. 2, Table 2) in Sump 1( A) to correspond to adult sucker use areas as determined by studies of radio- marked adult suckers conducted by Reclamation in 1993- 95 ( Fig. 3). We selected 2 sites in Sump 1( B) which met or exceeded the minimum depth requirement (> 3ft) for both sucker species ( M. Buettner, pers. comm.) after referring to 1986 bathymetric maps. We attempted to obtain data from each site twice/ month. We moved 2 sample sites ( Donut Hole and Donut Hole Northwest) early in the summer and 1 site ( Donut Hole West) ( Fig. 2) during mid- summer to better represent summer use locations of radio- marked fish. From May through November, we measured water quality parameters ( dissolved oxygen ( DO), hydrogen ion concentration ( pH), and temperature (° C)) using DataSonde 3, 4 and 4a= s ( Hydrolab Corp., Austin, Texas) ( hereafter referred to as Hydrolabs) 26 cm ( 12 in) above the sediment. We suspended Hydrolabs, within PVC tubes, from metal fence posts driven into the sediment. Data were collected hourly over a 96 hr period at each monitoring site. We downloaded data from Hydrolabs using the Hyperterminal software package v. 690170 to a personal computer. Unit probes were cleaned and calibrated according to Hydrolab guidelines ( Hydrolab Corporation 1997) and local geographic standards. Using the same deployment schedule as with our Hydrolabs, we sampled turbidity at each site using a Portable Turbidimeter model 21 OOP ( Hach Corp., P. O. Box 389, Loveland, CO 80539). We collected water samples 27 cm ( 12 in) above the sediment at each sample site. We measured turbidity in NTUs, following the guidelines in the product manual and we measured water depth using a hand- crafted wooden pole, marked in measured increments. We summarized water quality data using Microsoft 8 EXCEL software v. 97 SR- 1 and SPSS for Windows release 9.0.0. Because of the apparent difference in summer water quality in the DH versus other sampling sites, data were summarized as DH sites and Non- DH ( NDH) sites.

Results Radio- marked suckers We located fish 231 times in locations similar to those determined by Reclamation biologists in 1993- 95 ( Figs 3- 4). Lost River and shortnose suckers did not appear to differentiate use of the sump by species; we located both species intermixed throughout the monitoring period. With the exception DH and DHNW ( Fig. 2), water quality sampling sites were close to seasonal sucker use areas. Of 14 suckers marked, mortality occurred in only 1 fish. A Lost River sucker (# X9) was tagged on 18 May at the Anderson Rose Dam; she was not located again until 23 days later on 9 June. From 9 June to 17 November, # X9 was located by signal within approximately 15 m of the original location based on the location data. It is likely that this fish died in early June within 2- 3 weeks of being radio- marked. It is unknown if this mortality was related to the stress of handling and marking or some other cause. April - May - In April- May, a period of maximum fish movements ( Figs. 5- 18), most suckers congregated in the AEnglish Channel ® between the sumps with a scattering offish located between the northwest corner of Sump 1( A) and the AEnglish Channel ® ( Fig. 4). Only 1 fish radio- marked in Tule Lake moved into the Lost River. This particular fish, a female shortnose sucker (# G9) was radio- marked in the northwest corner of Tule Lake on 9 April, was located in the AEnglish Channel ® on 14 April, and subsequently was located in Lost River below Anderson Rose Dam on 29 April and 6 May.

Movements of radio- marked sucker X9 on Tule Lake National Wildlife Refuge, California, 1999. 25 June - September - During this period, nearly all suckers ( particularly during July and August) could be found in the DH at the south central portion of Sump 1( A) ( Fig. 4). By connecting the outermost locations of approximately 90% of radio locations, the calculated area of the DH was 188 ha. Suckers using the DH were found in depths ranging from 1.0- 1.3 m ( 39- 50 in) ( Fig. 19). September - December - During this period suckers moved from the DH to the northwest corner of Sump 1( A). As of the writing of this report, ( February 15, 2000) the 13 remaining fish occupy the same area. Recruitment Surveys by Reclamation biologists for larval and juvenile suckers in the Lost River below Anderson- Rose Dam failed to document the presence young of the year fish. Below is a summary of surveys: Date 5/ 25/ 99 6/ 2/ 99 6/ 10/ 99 Result Searches for eggs in gravel below Anderson- Rose Dam revealed eggs in 4 of 5 sites, some of which were viable. Larval surveys conducted at 3 sites ( visual and dip net) from the dam to the wooden bridge were negative. Larval surveys conducted at 5 sites including the dam, 2 and 1 mile downstream, the wooden bridge, and East- West Road were negative. Larval surveys conducted at 2 sites downstream of dam were negative. Water quality pHBln general, pH values were less variable in the DH then areas outside this region ( Fig. 20). In all areas, median pH values remained below 9.5 until early June at which time values outside the DH were frequently above 10.0. pH values were particularly high (> 10.0) in late June through August in ESIB and NWS1A and periodically in the EC and WS1B. pH values in the DH and areas adjacent, remained below 10.0 through September; however, there was a gradual rise in pH values in DH sites from May through September. In late September and early October, DH pH values exceeded all other sites. rem/ reratareBTemperatures in all regions reached a peak in late July through early August with no discernible difference between DH or NDH sites ( Fig. 21). Dissolved oxvgenBDonut Hole sampling station s differed in dissolved oxygen characteristics relative to other areas of the sumps. During the June through August period DH sites ranged from 4.5 to 11.2 mg/ 1 while areas outside this region ranged from 1.1 mg/ 1 to 18.2 mg/ 1 ( Fig. 21). Toward November DH and NDH sites became similar DO dynamics ( Fig. 21). 26 Turbiditvllln general, turbidity values appeared greater in the DH versus areas outside, although some sites particularly in Sump 1( B) were quite variable particularly in June and July. This may have been due to the large amount of filamentous algae in Sump 1( B), potentially interfering with the measurement. Turbidity rose sharply at sites by late October and November ( Fig. 23- 24). 20 >• 1 5 O UJ a UJ DC 10 0 39 41 43 45 47 More DEPTH Figure 19.

Turbidity at non- Donut Hole sites on Tule Lake National Wildlife Refuge, California, 1999. 33 Discussion Water Quality The area of the DH was delineated from plotted June through September locations of radio-marked suckers ( approximately 188 ha.). The location of the DH could also be seen as an area of relatively turbid water from aerial photographs from August 1998 ( Fig. 25) as well as aerial photographs taken in 1984. It is possible that the combination of 2 factors may cause the observed turbidity in the DH. First, seeps or springs may be present in the area which result in more favorable water quality during summer which attracts suckers as well as other fish species to the area. The resultant concentration offish ( suckers and chubs) may stir the sediments during feeding activities, thereby creating the observed turbidity. The additional turbidity in the DH may inhibit light penetration and the production of algae, thereby reducing photo synthetically elevated pH and the extreme minimum and maximums in DO typical of may water bodies in the Klamath Basin including Tule Lake ( Dileanis et al. 1996). The rise in turbidity at all sites in fall is likely due to the break down of rooted aquatic vegetation which then allows for wind induced wave action to stir the sediments. Other than the DH, all other sites had dense concentrations of rooted aquatic plants and/ or filamentous green algae during summer. June to September DO and pH dynamics in the DH appeared different than at NDH sites ( Figs. 20 and 22). The difference was greatest in early summer with the difference becoming smaller by late summer and essentially disappearing by fall. Whether this water quality difference was a result of the more turbid waters or inflow from springs is unknown. However, attempts by Service hydrologists to model inflows, evapotranspiration, and outflows from the sumps have resulted in a positive imbalance of approximately 21,000 acre- feet of water from April through September. This positive imbalance is greatest in spring and early summer, gradually lessening by summer and essentially disappearing by fall ( Tim Mayer, pers. comm.). If this inflow is occurring, it may explain differences in summer water quality between DH and NDH sites. June to September water quality in the DH may be critical to the over summer survival of suckers in Tule Lake as pH and DO in NDH sites during summer often exceeded the tolerance limits for the fish. DO and pH levels at DH sites were less variable and did not reach the extremes that were reached in NDH sites. The lowest DO measured during June through September at DH sites were 4.83 mg/ 1 ( DHWEST) and 4.96 mg/ 1 ( DHEAST). DO and pH during summer from this study were similar to values collected by Reclamation in 1992 ( Table 3). Buettner and Scoppettone ( 1990) found juvenile suckers only where DO was above 4.5 mg/ 1. It is currently believed that adult suckers become stressed at DO levels below 4.0 mg/ 1 with mortality occurring at or below 2.0 mg/ 1 ( M. Buettner, pers. comm.). The relatively high over- summer survival of radio- marked suckers, compared to suckers radio- marked in Upper Klamath Lake ( M. Buettner, pers. comm), is further evidence of suitable summer water quality conditions in the DH on Tule Lake. 34 Figure 25. " Donut Hole" in Sump 1( A) of Tule Lake NWR.

( Data from U. S. Bureau of Reclamation) pH levels in the DH generally remained below 10.0 whereas non DH sites frequently exceeded 10.0 ( Fig. 19). Falter and Cech ( 1991) determined a maximum pH tolerance in shortnose suckers of 9.55+ 0.43 under laboratory conditions, levels generally exceeded in June - September at non DH sites and some DH sites in late summer. Buettner and Scoppettone ( 1990) found juvenile fish in Upper Klamath Lake largely at sites with pH < 9.0, as did Simon et al. ( 1996) in 1994. However, in 1995, Simon et al. ( 1996) found that most juvenile fish ( 54%) were captured in areas of higher pH (> 10.0). Laboratory studies indicate significant mortality of larval and juvenile fish at high pH values (> 9.55) ( Falter and Cech 1991) and 9.92- 10.46 ( Bellerud and Saiki 1995). Previous water quality and fish health studies on the refuge determined that water quality conditions were stressful to aquatic life and was resulting in a high ( up to 37%) proportion offish with deformities ( Dileanis et al. 1996), however, studies of sucker ecology in Tule Lake have indicated that individual fish in the lake have a high condition factor and are free of external parasites ( Scoppettone and Buettner 1995). Bennet ( 1994) recognized this apparent inconsistency, stating, A... the observation that Tule Lake suckers are in better physical condition than Upper Klamath Lake suckers indicates that certain areas of the aquatic system may be of particular importance for the recovery of those species. ® In the case of Tule Lake this Acertain area@ is likely the DH.. Suckers in Tule Lake may be in good condition because of their limited population size, the abundant food resources in this lake, and adequate water quality ( in the DH) to survive the summer period. 36 Sucker movements Although, suckers were relatively sedentary during most periods of the year, they exhibited the ability to make long distance moves in relatively short periods of time, particularly during the April spawning period. The northwest corner of Sump 1( A) receives about 90% of the inflow from the Lost River and spring winds on Tule Lake tend to move large quantities of water through the AEnglish Channels back and forth between Sump 1( A) and 1( B). This movement of water at both locations may explain the movement of fish observed in April and May. Suckers may be attracted to both locations when seeking spawning habitat in spring. Recruitment During the April marking period, most captured suckers appeared to be physiologically ready to spawn; however, only one fish moved into the river. Of 10 radio- marked fish monitored by Reclamation in 1993- 95 no fish attempted to run the Lost River. This low proportion offish that attempt to spawn may have one or several causes or a combination, including: 1. Stress of handling and implanting radio- transmitters so close to the spawning season may prevent fish from becoming reproductively active. 2. Under normal conditions, only a small proportion of Tule Lake suckers may attempt to spawn in any particular year. 3. Flow conditions in or at the mouth of the Lost River may be inadequate to draw the fish into the river. 4. A shallow bar (< 0.3 m) of deposited silt exists between the lake and the mouth of the river which may form a physical barrier to the fish. At the present time, a mandated flow of 30 cfs is released below Anderson- Rose Dam to provide spawning habitat at the Dam. Although this flow is intended to provide suitable spawning conditions at the Dam, these flows may be inadequate to entice fish into the river. It is likely that the historic spring flows in the Lost River were many times higher than current regulated flows. However, given that the fish are largely unsuccessful in spawning and risk additional mortality traversing the river, adult survival may be enhanced by remaining in the lake. Scoppettone and Buettner ( 1995) also observed no radio- marked fish from Clear Lake to move into Willow Creek during the spring spawning period. In this case the authors attributed this result to either capture stress or low stream flows during spring. 37 Habitat use Although the DH is relatively shallow relative to other areas of Tule Lake, use of the DH may be mandatory to ensure over- summer survival. Although deeper waters are available to the fish, especially in the northwest corner of Sump 1( A), DO levels, in particular, likely preclude their use. Suckers did not move out of the DH until October when DO levels began to rise with cooler water temperatures. Although, Sump 1( B) contained suitable water depths and water quality conditions in fall, no suckers were located in this area. It is possible that suckers may prefer not to pass through the pipes connecting the Sumps or the proximity and flow from the Lost River in the northwest corner of Sump 1( A) may make this area more attractive as an over- winter habitat area. The relative lack of water depth in the DH as well as other areas of the sumps is becoming of increasing concern because of the loss of water depth through sedimentation. If suckers require a minimum of 3 ft of water, as is current believed ( M. Buettner, pers. comm.), current rates of sedimentation in the sumps threaten the future suitability of Tule Lake for suckers. Based on a comparison of bathymetric surveys conducted by Reclamation in 1958 and again in 1986, sedimentation has been steadily reducing the water holding capacity of both sumps. Between the 1958 and 1986 surveys ( 28 years), Sump 1( A) has lost 22.4% of its water capacity and Sump 1( B) has lost 30.8% of its capacity due to sedimentation. This would indicate a total mean sedimentation of 11.8 inches over this time period ( U. S. Bureau of Reclamation, unpubl. rep). Over the last several years, an attempt has been made to store additional water in Tule Lake during summer by raising water levels above 4034.60 ft. This increase in water elevations ( between 4034.60 and 4034.90 ft) has somewhat mitigated the loss of depth through sedimentation. However, without reinforcing and raising the levees around the sumps, there is a limit as to how high water elevations can rise. At elevation 4035.50 ft., operating regulations require breaching the sumps into overflow areas ( Sump 2 or 3). Although increased summer operating levels may assist the fish, they may also increase the risk of a flood event requiring the breaching of the sumps with potentially negative impacts to the fish.

Fish and Wildlife Service, Klamath Basin National Wildlife Refuge, Route 1, Box 74, Tulelake, CA 96134 Introduction The Lost River ( Deltistes luxatus) and shortnose ( Chasmistes brevirostris) suckers were federally listed as endangered species on July 18, 1988 ( Federal Register 53: 27130- 27134). Both sucker species are relatively long- lived, have a limited geographic range, and are endemic to the Upper Klamath Basin of Northern California and Southern Oregon. Habitat degradation from water diversions and loss of riparian and wetlands habitats associated with agricultural development within their historic range is believed to be the major reason for the species decline ( U. S. Fish and Wildlife Service 1993). A more detailed description on the life history, habitat requirements, and causes of decline of the species can be found in the Lost River and Shortnose Sucker Recovery Plan ( U. S. Fish and Wildlife Service 1993). Tule Lake National Wildlife Refuge ( NWR), established in 1928, consists of 2 return flow sumps ( Sump 1( A) and 1( B)) totaling 13,000 acres surrounded by 17,000 acres of intensively farmed lands ( Fig. 1). The refuge and surrounding private agricultural lands occupy the historic lake bed of Tule Lake, a 95,000 acre lake and marsh area that was reclaimed in the early 1900fs as part of the Klamath Reclamation Project. Current management of the refuge is directed by the Kuchel Act of 1964 which mandates the refuge be managed for the major purpose of waterfowl management but with optimal agricultural use that is consistent therewith. Both sumps are shallow ( 0.1 - 2.0 m) and consist of approximately 10,500 acres of open water with a 2,500 acre shallow (< 0.1 m) emergent marsh at the northeast corner of Sump 1( A). Tule Lake has been identified as a potential refugia for both sucker species ( U. S. Fish and Wildlife Service 1993). Tule T like National Wildlife Sump 3 Lease lands Field .

During winter, water within the sumps is comprised primarily of local runoff and during summer water is comprised primarily of irrigation return flows, originating from Upper Klamath Lake. Summer water quality in the sumps is similar to other water bodies within the Upper Klamath Basin and is considered hypereutrophic ( Dileanis et al. 1996). Water quality problems include low dissolved oxygen ( DO) and high hydrogen ion concentrations ( pH) and unionized ammonia. Water quality in the Tule Lake sumps is directly affected by hypereutrophic conditions in Upper Klamath Lake ( U. S. Fish and Wildlife Service 1993). Studies conducted after publication of the Shortnose and Lost River Sucker Recovery Plan indicate that Tule Lake contains an estimated 159 ( 95% CI = 48- 289) shortnose and 105 ( 95% CI = 25- 175) Lost River suckers ( Scoppetone and Buettner 1995). Confidence intervals for these estimates are large because of small sample sizes and low rates of recapture. Recruitment rates for the Tule Lake population via spawning below Anderson- Rose Dam is low with significant larval production occurring only in 1995 ( monitoring occurred 1991- 99) ( M. Buettner, pers. comm). Entrainment from the irrigation system is likely the largest source offish for Tule Lake ( U. S. Bureau of Reclamation 1998). Both species of suckers in Tule lake are in good physical condition relative to fish in Clear Lake and Upper Klamath Lake with Tule Lake fish being generally heavier and exhibiting few if any problems with parasites or lamprey. ( Scoppetone and Buettner 1995). U. S. Bureau of Reclamation ( Reclamation) biologists tracked 10 radio- marked suckers in Tule Lake from 1993- 95. From these studies, specific use areas by time period were identified with over 99% of radio locations occurring in Sump 1( A). Of particular importance from these studies was identification of an over- summer site in the south central region of Sump 1( A) termed the ADonut Hole# ( DH). In early 1999, the U. S. Fish and Wildlife Service ( Service) proposed a wetland enhancement project on the 3,500 acre Sump 1( B). The project was designed to improve habitat for waterfowl and other associated wetland species as well as improve water quality through the conversion of Sump 1( B) from an open body of shallow water to an emergent year- round flooded wetland. The primary mechanism to create the desired habitat condition is a series of annual spring/ summer drawdowns thereby creating conditions suitable for germination of desired emergent plant species. Of principal concern in developing the project was the potential effects on suckers within the sumps. Because of the proximity of both sucker species in adjacent Sump 1( A), a project monitoring plan was developed to ascertain the potential effects of the Sump 1( B) Project on suckers and water quality. Our monitoring design benefitted from studies of water quality and sucker movements by Reclamation biologists from 1992- 95. This report summarizes findings of the first year= s pre- project monitoring effort ( April- December, 1999) relative to water quality and movements of radio- marked suckers. Objectives 1. Describe seasonal distribution and movement patterns of both sucker species in Tule Lake NWR and determine if fish movements have changed since initial studies by Reclamation biologists in 1993- 95. 2. Characterize water quality, in space and time, of areas used by adult suckers compared to areas which are not used. 3. Document and describe movements of radio- marked suckers to spawning areas below Anderson- Rose dam. 4. Determine whether recruitment of larvae and juvenile was occurring below Anderson- Rose Dam. Methods Monitoring radio- marked adult suckers In April and May, 1999, Reclamation biologists captured 14 suckers and surgically implanted radio- transmitters ( ATS, Isanti, MN) having a projected battery life of 12 months. Each transmitter had an external antennae that exited the body cavity near the lateral line of the fish. Eleven Lost River and 3 shortnose suckers were captured using trammel nets at the northwest corner of Sump 1( A) ( 9 fish) and immediately downstream of Anderson- Rose Dam on the Lost River ( 5 fish) ( Table 1). We located radio- marked fish via air thrust boats using a scanning receiver and 4- element yagi antennae. Fish were located fish 4 times/ month during March and April, 2 times/ month from May through September, and once per month from October through December. Fish not located via boat were located from fixed wing aircraft. We determined fish locations by moving as close as possible to undisturbed fish and recording locations with a Global Positioning System ( GPS). All GPS positions consisted of 180 rover points/ location and were differentially corrected via post processing software ( PFinder ver. 2.11). We recorded depth information at each fish location. To determine timing and duration of the spawning migration, we monitored radio-marked fish from vehicles on the east levee of the Lost River downstream of Anderson- Rose Dam. Table 1.

Egg viability surveys were conducted in the gravel sediments immediately below the dam in May. Water quality We preselected water quality sampling sites ( Fig. 2, Table 2) in Sump 1( A) to correspond to adult sucker use areas as determined by studies of radio- marked adult suckers conducted by Reclamation in 1993- 95 ( Fig. 3). We selected 2 sites in Sump 1( B) which met or exceeded the minimum depth requirement (> 3ft) for both sucker species ( M. Buettner, pers. comm.) after referring to 1986 bathymetric maps. We attempted to obtain data from each site twice/ month. We moved 2 sample sites ( Donut Hole and Donut Hole Northwest) early in the summer and 1 site ( Donut Hole West) ( Fig. 2) during mid- summer to better represent summer use locations of radio- marked fish. From May through November, we measured water quality parameters ( dissolved oxygen ( DO), hydrogen ion concentration ( pH), and temperature (° C)) using DataSonde 3, 4 and 4a= s ( Hydrolab Corp., Austin, Texas) ( hereafter referred to as Hydrolabs) 26 cm ( 12 in) above the sediment. We suspended Hydrolabs, within PVC tubes, from metal fence posts driven into the sediment. Data were collected hourly over a 96 hr period at each monitoring site. We downloaded data from Hydrolabs using the Hyperterminal software package v. 690170 to a personal computer. Unit probes were cleaned and calibrated according to Hydrolab guidelines ( Hydrolab Corporation 1997) and local geographic standards. Using the same deployment schedule as with our Hydrolabs, we sampled turbidity at each site using a Portable Turbidimeter model 21 OOP ( Hach Corp., P. O. Box 389, Loveland, CO 80539). We collected water samples 27 cm ( 12 in) above the sediment at each sample site. We measured turbidity in NTUs, following the guidelines in the product manual and we measured water depth using a hand- crafted wooden pole, marked in measured increments. We summarized water quality data using Microsoft 8 EXCEL software v. 97 SR- 1 and SPSS for Windows release 9.0.0. Because of the apparent difference in summer water quality in the DH versus other sampling sites, data were summarized as DH sites and Non- DH ( NDH) sites.

Results Radio- marked suckers We located fish 231 times in locations similar to those determined by Reclamation biologists in 1993- 95 ( Figs 3- 4). Lost River and shortnose suckers did not appear to differentiate use of the sump by species; we located both species intermixed throughout the monitoring period. With the exception DH and DHNW ( Fig. 2), water quality sampling sites were close to seasonal sucker use areas. Of 14 suckers marked, mortality occurred in only 1 fish. A Lost River sucker (# X9) was tagged on 18 May at the Anderson Rose Dam; she was not located again until 23 days later on 9 June. From 9 June to 17 November, # X9 was located by signal within approximately 15 m of the original location based on the location data. It is likely that this fish died in early June within 2- 3 weeks of being radio- marked. It is unknown if this mortality was related to the stress of handling and marking or some other cause. April - May - In April- May, a period of maximum fish movements ( Figs. 5- 18), most suckers congregated in the AEnglish Channel ® between the sumps with a scattering offish located between the northwest corner of Sump 1( A) and the AEnglish Channel ® ( Fig. 4). Only 1 fish radio- marked in Tule Lake moved into the Lost River. This particular fish, a female shortnose sucker (# G9) was radio- marked in the northwest corner of Tule Lake on 9 April, was located in the AEnglish Channel ® on 14 April, and subsequently was located in Lost River below Anderson Rose Dam on 29 April and 6 May.

Movements of radio- marked sucker X9 on Tule Lake National Wildlife Refuge, California, 1999. 25 June - September - During this period, nearly all suckers ( particularly during July and August) could be found in the DH at the south central portion of Sump 1( A) ( Fig. 4). By connecting the outermost locations of approximately 90% of radio locations, the calculated area of the DH was 188 ha. Suckers using the DH were found in depths ranging from 1.0- 1.3 m ( 39- 50 in) ( Fig. 19). September - December - During this period suckers moved from the DH to the northwest corner of Sump 1( A). As of the writing of this report, ( February 15, 2000) the 13 remaining fish occupy the same area. Recruitment Surveys by Reclamation biologists for larval and juvenile suckers in the Lost River below Anderson- Rose Dam failed to document the presence young of the year fish. Below is a summary of surveys: Date 5/ 25/ 99 6/ 2/ 99 6/ 10/ 99 Result Searches for eggs in gravel below Anderson- Rose Dam revealed eggs in 4 of 5 sites, some of which were viable. Larval surveys conducted at 3 sites ( visual and dip net) from the dam to the wooden bridge were negative. Larval surveys conducted at 5 sites including the dam, 2 and 1 mile downstream, the wooden bridge, and East- West Road were negative. Larval surveys conducted at 2 sites downstream of dam were negative. Water quality pHBln general, pH values were less variable in the DH then areas outside this region ( Fig. 20). In all areas, median pH values remained below 9.5 until early June at which time values outside the DH were frequently above 10.0. pH values were particularly high (> 10.0) in late June through August in ESIB and NWS1A and periodically in the EC and WS1B. pH values in the DH and areas adjacent, remained below 10.0 through September; however, there was a gradual rise in pH values in DH sites from May through September. In late September and early October, DH pH values exceeded all other sites. rem/ reratareBTemperatures in all regions reached a peak in late July through early August with no discernible difference between DH or NDH sites ( Fig. 21). Dissolved oxvgenBDonut Hole sampling station s differed in dissolved oxygen characteristics relative to other areas of the sumps. During the June through August period DH sites ranged from 4.5 to 11.2 mg/ 1 while areas outside this region ranged from 1.1 mg/ 1 to 18.2 mg/ 1 ( Fig. 21). Toward November DH and NDH sites became similar DO dynamics ( Fig. 21). 26 Turbiditvllln general, turbidity values appeared greater in the DH versus areas outside, although some sites particularly in Sump 1( B) were quite variable particularly in June and July. This may have been due to the large amount of filamentous algae in Sump 1( B), potentially interfering with the measurement. Turbidity rose sharply at sites by late October and November ( Fig. 23- 24). 20 >• 1 5 O UJ a UJ DC 10 0 39 41 43 45 47 More DEPTH Figure 19.

Turbidity at non- Donut Hole sites on Tule Lake National Wildlife Refuge, California, 1999. 33 Discussion Water Quality The area of the DH was delineated from plotted June through September locations of radio-marked suckers ( approximately 188 ha.). The location of the DH could also be seen as an area of relatively turbid water from aerial photographs from August 1998 ( Fig. 25) as well as aerial photographs taken in 1984. It is possible that the combination of 2 factors may cause the observed turbidity in the DH. First, seeps or springs may be present in the area which result in more favorable water quality during summer which attracts suckers as well as other fish species to the area. The resultant concentration offish ( suckers and chubs) may stir the sediments during feeding activities, thereby creating the observed turbidity. The additional turbidity in the DH may inhibit light penetration and the production of algae, thereby reducing photo synthetically elevated pH and the extreme minimum and maximums in DO typical of may water bodies in the Klamath Basin including Tule Lake ( Dileanis et al. 1996). The rise in turbidity at all sites in fall is likely due to the break down of rooted aquatic vegetation which then allows for wind induced wave action to stir the sediments. Other than the DH, all other sites had dense concentrations of rooted aquatic plants and/ or filamentous green algae during summer. June to September DO and pH dynamics in the DH appeared different than at NDH sites ( Figs. 20 and 22). The difference was greatest in early summer with the difference becoming smaller by late summer and essentially disappearing by fall. Whether this water quality difference was a result of the more turbid waters or inflow from springs is unknown. However, attempts by Service hydrologists to model inflows, evapotranspiration, and outflows from the sumps have resulted in a positive imbalance of approximately 21,000 acre- feet of water from April through September. This positive imbalance is greatest in spring and early summer, gradually lessening by summer and essentially disappearing by fall ( Tim Mayer, pers. comm.). If this inflow is occurring, it may explain differences in summer water quality between DH and NDH sites. June to September water quality in the DH may be critical to the over summer survival of suckers in Tule Lake as pH and DO in NDH sites during summer often exceeded the tolerance limits for the fish. DO and pH levels at DH sites were less variable and did not reach the extremes that were reached in NDH sites. The lowest DO measured during June through September at DH sites were 4.83 mg/ 1 ( DHWEST) and 4.96 mg/ 1 ( DHEAST). DO and pH during summer from this study were similar to values collected by Reclamation in 1992 ( Table 3). Buettner and Scoppettone ( 1990) found juvenile suckers only where DO was above 4.5 mg/ 1. It is currently believed that adult suckers become stressed at DO levels below 4.0 mg/ 1 with mortality occurring at or below 2.0 mg/ 1 ( M. Buettner, pers. comm.). The relatively high over- summer survival of radio- marked suckers, compared to suckers radio- marked in Upper Klamath Lake ( M. Buettner, pers. comm), is further evidence of suitable summer water quality conditions in the DH on Tule Lake. 34 Figure 25. " Donut Hole" in Sump 1( A) of Tule Lake NWR.

( Data from U. S. Bureau of Reclamation) pH levels in the DH generally remained below 10.0 whereas non DH sites frequently exceeded 10.0 ( Fig. 19). Falter and Cech ( 1991) determined a maximum pH tolerance in shortnose suckers of 9.55+ 0.43 under laboratory conditions, levels generally exceeded in June - September at non DH sites and some DH sites in late summer. Buettner and Scoppettone ( 1990) found juvenile fish in Upper Klamath Lake largely at sites with pH < 9.0, as did Simon et al. ( 1996) in 1994. However, in 1995, Simon et al. ( 1996) found that most juvenile fish ( 54%) were captured in areas of higher pH (> 10.0). Laboratory studies indicate significant mortality of larval and juvenile fish at high pH values (> 9.55) ( Falter and Cech 1991) and 9.92- 10.46 ( Bellerud and Saiki 1995). Previous water quality and fish health studies on the refuge determined that water quality conditions were stressful to aquatic life and was resulting in a high ( up to 37%) proportion offish with deformities ( Dileanis et al. 1996), however, studies of sucker ecology in Tule Lake have indicated that individual fish in the lake have a high condition factor and are free of external parasites ( Scoppettone and Buettner 1995). Bennet ( 1994) recognized this apparent inconsistency, stating, A... the observation that Tule Lake suckers are in better physical condition than Upper Klamath Lake suckers indicates that certain areas of the aquatic system may be of particular importance for the recovery of those species. ® In the case of Tule Lake this Acertain area@ is likely the DH.. Suckers in Tule Lake may be in good condition because of their limited population size, the abundant food resources in this lake, and adequate water quality ( in the DH) to survive the summer period. 36 Sucker movements Although, suckers were relatively sedentary during most periods of the year, they exhibited the ability to make long distance moves in relatively short periods of time, particularly during the April spawning period. The northwest corner of Sump 1( A) receives about 90% of the inflow from the Lost River and spring winds on Tule Lake tend to move large quantities of water through the AEnglish Channels back and forth between Sump 1( A) and 1( B). This movement of water at both locations may explain the movement of fish observed in April and May. Suckers may be attracted to both locations when seeking spawning habitat in spring. Recruitment During the April marking period, most captured suckers appeared to be physiologically ready to spawn; however, only one fish moved into the river. Of 10 radio- marked fish monitored by Reclamation in 1993- 95 no fish attempted to run the Lost River. This low proportion offish that attempt to spawn may have one or several causes or a combination, including: 1. Stress of handling and implanting radio- transmitters so close to the spawning season may prevent fish from becoming reproductively active. 2. Under normal conditions, only a small proportion of Tule Lake suckers may attempt to spawn in any particular year. 3. Flow conditions in or at the mouth of the Lost River may be inadequate to draw the fish into the river. 4. A shallow bar (< 0.3 m) of deposited silt exists between the lake and the mouth of the river which may form a physical barrier to the fish. At the present time, a mandated flow of 30 cfs is released below Anderson- Rose Dam to provide spawning habitat at the Dam. Although this flow is intended to provide suitable spawning conditions at the Dam, these flows may be inadequate to entice fish into the river. It is likely that the historic spring flows in the Lost River were many times higher than current regulated flows. However, given that the fish are largely unsuccessful in spawning and risk additional mortality traversing the river, adult survival may be enhanced by remaining in the lake. Scoppettone and Buettner ( 1995) also observed no radio- marked fish from Clear Lake to move into Willow Creek during the spring spawning period. In this case the authors attributed this result to either capture stress or low stream flows during spring. 37 Habitat use Although the DH is relatively shallow relative to other areas of Tule Lake, use of the DH may be mandatory to ensure over- summer survival. Although deeper waters are available to the fish, especially in the northwest corner of Sump 1( A), DO levels, in particular, likely preclude their use. Suckers did not move out of the DH until October when DO levels began to rise with cooler water temperatures. Although, Sump 1( B) contained suitable water depths and water quality conditions in fall, no suckers were located in this area. It is possible that suckers may prefer not to pass through the pipes connecting the Sumps or the proximity and flow from the Lost River in the northwest corner of Sump 1( A) may make this area more attractive as an over- winter habitat area. The relative lack of water depth in the DH as well as other areas of the sumps is becoming of increasing concern because of the loss of water depth through sedimentation. If suckers require a minimum of 3 ft of water, as is current believed ( M. Buettner, pers. comm.), current rates of sedimentation in the sumps threaten the future suitability of Tule Lake for suckers. Based on a comparison of bathymetric surveys conducted by Reclamation in 1958 and again in 1986, sedimentation has been steadily reducing the water holding capacity of both sumps. Between the 1958 and 1986 surveys ( 28 years), Sump 1( A) has lost 22.4% of its water capacity and Sump 1( B) has lost 30.8% of its capacity due to sedimentation. This would indicate a total mean sedimentation of 11.8 inches over this time period ( U. S. Bureau of Reclamation, unpubl. rep). Over the last several years, an attempt has been made to store additional water in Tule Lake during summer by raising water levels above 4034.60 ft. This increase in water elevations ( between 4034.60 and 4034.90 ft) has somewhat mitigated the loss of depth through sedimentation. However, without reinforcing and raising the levees around the sumps, there is a limit as to how high water elevations can rise. At elevation 4035.50 ft., operating regulations require breaching the sumps into overflow areas ( Sump 2 or 3). Although increased summer operating levels may assist the fish, they may also increase the risk of a flood event requiring the breaching of the sumps with potentially negative impacts to the fish.

  	Citation × Citation Citation Abstract Copy Title: School-based Klamath River restoration project, phases V, VI & VII, 319h Clean Water Act Author: Rilling, Trudy S. Year: 2000, 2005 ABSTRACT Phase VI of the School-Based Klamath Restoration Project (319h) is a collaborative effort between seven Siskiyou County schools, the Siskiyou County Office of Education (SCOE), and the United States Fish and Wildlife Service (USFWS). The objectives of the project include: ? Expanding hands-on field science watershed education. ? Encouraging a sense of resource stewardship among students at all grade levels. ? Collecting quality data for inclusion in the 319h data base. ? Teaching applications of the scientific method. ? Providing on-going inservice training for teachers to increase the effectiveness of the project. Project tasks that were completed include acquisition and analysis of Klamath River Watershed Data, including river water temperatures, river cross sectional profiles and spawning ground surveys. Descriptions of methodology are included in the report. Many other watershed-related projects were undertaken by schools. In some cases the field data was collected and compiled by agency personnel. The spawning ground survey data collected by student volunteers was part of a project conducted by the California Department of Fish and Game and the U.S. Forest Service. Although a substantial amount of excellent work has been accomplished by the schools, the opportunity exists to improve the program at all levels. Increased field and technical support is needed to successfully integrate the goals of the project. Computer training for teachers and students is an essential component of the project, which would allow analysis of data and creation of web sites within classrooms. Data analysis and reporting is the critical component of the project that would provide students with a complete understanding of scientific research methodology. Providing a forum for communication between the 319h participants is another important area of the project that needs to be expanded. Travel time, mountainous topography, and intense winter storms can be barriers to travel in Siskiyou County. Communication helps to increase the level of standardization of data collection and transfer and gives teachers a chance to share successful ideas. Communication also sustains the positive momentum of the project, reinforcing the idea of working as a team towards establishing common goals for watershed education.

  	Citation × Citation Citation Abstract Copy Title: Water temperature monitoring of the Klamath River mainstem: final report Author: Karuk Tribe of California Year: 1999, 2005 WATER TEMPERATURE MONITORING KLAMATH RIVER MAINSTEM ABSTRACT This report summarizes the water temperature data collected by the Karuk Tribe of California (Karuk Tribe) from July 1993 to September 1997 at thirteen locations along the Klamath River from Upper Klamath Lake to the mouth of the Klamath River at the Pacific Ocean. This report describes the water temperature monitoring system designed by the Karuk Tribe, the data checks that were performed, and a summary of the water temperature data results. The Karuk Tribe began this study in part in response to the Klamath River Basin Fisheries Task Force stated objective to monitor water temperature conditions above, within, and below existing water projects along the Klamath River. With help from the California Department of Fish and Game, PacifiCorp, and the Klamath National Forest, this project was expanded from six to thirteen original monitoring sites in 1993. Water temperature data were collected by Ryan TempMentor? instruments typically on an hourly time interval. The data was checked for accuracy by consultants and reduced for this report to mean daily water temperature values each year on a monthly basis in US Geological Survey tabular format. Mean value data were entered into a Microsoft Access relational database for use on an IBM compatible computer. Although the period of record for the Klamath River water temperature data stretches over 5 years, several gaps in data inhibit detailed analysis. The analysis presented, illustrates when the minimum and maximum preferred temperature ranges for salmonids are exceeded. In addition, preliminary temperature trend shows that in August water temperature values below Iron Gate Dam were lower than other monitoring stations further downstream. Conversely, water temperature values in October are warmer below Iron Gate than in the unregulated reaches of the Klamath River downstream. Given this information, it appears that releases from Iron Gate Dam do influence the natural water temperature balance in the Klamath River. To more accurately determine the extent of reservoir releases on the natural thermal environment, additional water temperature measurements need to be collected.

Year: 2004, 2006, 2005 By Lorraine E. Flint, Alan L. Flint, Debra S. Curry, Stewart A. Rounds, and Micelis C. Doyle Abstract The U.S. Geological Survey (USGS) collected water? quality data during 2002 and 2003 In the Lower Klamath River Basin, in northern California, to support studies of river conditions as they pertain to the viability of Chinook and Coho salmon and endangered suckers.

Natural Resources Conservation Service Year: 2004, 2005 1 i California Oregon Cover Photo: Lower Klamath National Wildlife Refuge at sunset Tupper Ansel Blake/ USFWS Map Detail Area: Upper Klamath River Basin ii T he Klamath River Basin presents numerous challenges as well as opportunities for its many water users. For years, farmers and ranchers in the basin have recognized the vital role they play in the health of their watershed. Working with conservation districts, the Natural Resources Conservation Service ( NRCS) and others, land managers continue to proactively find ways to enhance natural resources in the basin, benefiting wildlife and the environment. However, as it has across the western United States, drought hit home in the Klamath for those who depend on every drop of water to sustain their livelihood, culture and community. In the spring of 2001, the combination of drought and the impact of the Endangered Species Act triggered a shutdown of irrigation water during the growing season, drying up water resources to more than 2,000 farms and ranches. NRCS, in cooperation with local conservation districts, provided a quick infusion of technical assistance and $ 2 million in cost- share funding for cover crops through the Emergency Watershed Protection Program. As cover crops took hold, the seeds of a long- term solution took root in the NRCS/ conservation district partnership. The ability of the local office to receive funding, engage community members and other partners, plan resource improvements, implement actions, and monitor success proved to be an invaluable asset for the community. Helping private landowners develop and apply practical, common- sense solutions to complex resource issues will be the challenge of the conservation partnership well into the future. USDA, in concert with the locally led conservation districts, will continue to play a critical role by delivering technical and financial assistance to Klamath Basin farmers and ranchers. The Rapid Subbasin Assessments that follow are the first step in that process. The assessments are designed to help local decision- makers determine where investments in conservation will best benefit wildlife habitat, agriculture and other land uses in a compatible manner. It is our goal to provide a comprehensive overview of resource challenges and opportunities in the basin, and help decision- makers to prioritize their investments in areas that will best sustain multiple use of natural resources in the basin now and in the future.

Stretching across southern Oregon and northern California, the Klamath Basin has become synonymous with the water challenges that western water users face. As one example, agricultural commodities that need irrigation water to thrive – providing Americans with the cheapest domestic food supply in the world, face competition from the critical water needs of sucker fish, salmon and other threatened and endangered species. While that competition is understandable, more and more, conservation leaders in all industries have come to recognize that these water needs aren’t necessarily at odds with one another, and can in fact be compatible. While an example of the challenges today’s agricultural producers and conservationists face, the Klamath Basin has emerged as an example of how diverse interests can work together successfully. 2 Overview of the Upper Klamath Basin Upper Klamath Basin Description The Upper Klamath Basin is an area of high desert, wetlands, and the Klamath River. The river extends 250 miles from its headwaters at Upper Klamath Lake in south central Oregon to the west coast of northern California. The Upper Klamath Basin includes the US Bureau of Reclamation’s ( USBR) Klamath Project Area and the drainage area above Irongate Dam on the Klamath River. The basin’s lakes, marshes, and wetlands host an abundance of plant and animal species and include national wildlife refuges, parks, and forests. Agricultural production began around the turn of the 20th century, and with the creation of the Klamath Irrigation District in 1905, water diversions for irrigation began in earnest. A portion of these irrigated lands are in the USBR’s irrigation project. The ‘ project area,’ as it is commonly called, includes 188,000 of the 502,000 acres of private irrigated land in the basin. This includes lands leased from the various wildlife refuges that are supplied with water by the USBR. Privately irrigated acreages can vary from year to year, depending on USBR contracts and annual cropping cycles. In comparison, the majority of the private irrigated land - about 314,000 acres - in the basin is located outside the project area. Upper Klamath Basin Quick Facts: • Over 2.2 million acres are privately owned in the Upper Klamath Basin • 188,000 of the irrigated acres are in the US Bureau of Reclamation’s Irrigation Project • Approximately 502,000 acres of privately owned lands are irrigated • 314,000 acres of irrigated lands are outside the Project area 3 Overview of the Upper Klamath Basin The Role of Agriculture in the Basin Agricultural lands play a key role in a healthy ecosystem. Located on the Pacific Flyway, migratory birds like the American White Pelican and the Red- Necked Grebe use croplands in the Klamath Basin as an important feeding and resting stop. Deer graze on wheat and barley fields, and pheasants use both crop and rangelands for their nesting and feeding grounds. Progressive conservation leaders recognize that farming and fish and wildlife habitat are not mutually exclusive. Well- maintained farmland creates fish and wildlife habitat, contributing to a healthy watershed. They also recognize that opportunities will always exist to improve the condition of natural resources in the basin. To address those opportunities, conservation leaders in Oregon’s Klamath Falls Soil and Water Conservation District and California’s Lava Beds/ Butte Valley Resource Conservation District have proactively identified four key priorities tied to natural resource conservation. The districts asked experts at the USDA’s Natural Resources Conservation Service to help them develop a plan to determine what could be done on- farm to conserve water, increase water storage, improve water quality, and enhance fish and wildlife habitat. While so much of the attention to date in the Klamath Basin has been focused on water demand, these conservation leaders recognize demand is only one piece of the puzzle. Comprehensive solutions must also address water quality, storage and wildlife habitat. Conservation District Priorities 1) Conserve Water 2) Increase Water Storage 3) Improve Water Quality 4) Enhance Fish & Wildlife Habitat 4 Rapid Subbasin Assessments Conserving natural resources is the ultimate goal throughout the basin, and its success hinges on long- term solutions. At the request of local conservation districts, NRCS undertook an 18- month study of resource concerns, challenges and opportunities throughout the Upper Klamath Basin. The study was not intended to provide a detailed, quantitative analysis of the impacts of conservation work, but rather, to provide an initial estimate of where conservation investments would best address the districts’ four priority resource concerns. Beginning in the spring of 2002, NRCS planners collected information to enable the conservation districts, agencies, organizations, farmers, ranchers and others to make informed decisions in a timely manner about conservation and resource management in the basin. These Rapid Subbasin Assessments are intended to help leaders set priorities and determine the best actions to achieve their goals. As a part of the rapid subbasin assessment process, eight subbasins were delineated ( see map at left). A watershed planning team traveled through each subbasin, inventorying agricultural areas, identifying conservation opportunities and current levels of resource management, and estimating the impacts of these opportunities on the Conservation in the Upper Klamath Basin 5 Conservation in the Upper Klamath Basin conservation districts’ priority resource concerns. They focused their recommendations on areas that would provide the best benefit to the wide array of stakeholders in the Upper Klamath Basin. They also identified a number of socio- economic factors that must be taken into consideration when helping producers adapt to new management styles and conservation activities. Through NRCS, conservation districts and other federal, state and local entities, private land managers are working to identify ways they can more efficiently use – and share – the water they need. In the face of increasingly complex and politically polarized circumstances, a clear purpose and direction has arisen. The commitment of the local conservation partnership to identify the impacts of water shortages and to find solutions that will improve natural resource conservation will be key to the long- term viability of both endangered species and industries in the Upper Klamath Basin. The information that follows provides a summary of the conservation challenges and opportunities that NRCS staff found in their assessment. Recommendations for where financial and other resources can best be invested to improve natural resources, while sustaining the economy of the Upper Klamath Basin, are also identified. 6 Conservation in the Upper Klamath Basin Private Lands Conservation Accomplishments One component necessary to understanding future conservation opportunities in the basin is to recognize the current conservation work of private land managers. An indicator of these efforts is the work that has been undertaken in partnership with NRCS and the local conservation districts. In federal fiscal years 2002 and 2003, Upper Klamath Basin farmers and ranchers improved resource conditions on 18,877 acres of privately owned agricultural lands, with assistance from NRCS and the conservation districts. During this time, private land managers have worked with the conservation districts in the basin to: • improve the condition of 11,800 acres of grazing lands • conserve water and improve water quality on 13,656 acres • restore and establish 4,138 acres of wetlands and riparian areas • improve 281 acres of forest stands • establish resource management systems on 1,351 acres of cropland These conservation efforts were accomplished with a combination of private, state and federal funding. 7 Conservation in the Upper Klamath Basin Summary of Conservation Opportunities In addition to recognizing current conservation activities, the assessments define what can be accomplished with a strong conservation partnership in the Upper Klamath Basin. All too often, the debate about multi- use of water in the basin has focused on ways to reduce water demand. However, the basin’s many water users - including fish and wildlife - benefit just as much from improvements to water quality, water storage and wildlife habitat. Taken together, the recommendations that follow seek to utilize a comprehensive approach to all four resource priorities - with the goal of contributing to a sustainable, multi- use water system. While quantification of the results of conservation work in these four areas is difficult, there is no question that a comprehensive approach to natural resource improvement in the Upper Klamath Basin will result in accumulative long- term benefits for endangered fish species, wildlife habitat, agriculture, urban and other water uses. Agriculture cannot undertake these efforts alone. Private landowners and the general public both benefit from natural resources conservation in the Upper Klamath Basin. Because of this, public and private sources of funding from in and outside the region are necessary. Solutions of this magnitude also come with other social, political, and cultural costs. Upper Klamath Basin Quick Facts: • 1,400 farm families live in the Upper Klamath Basin • The Upper Klamath Basin is home to sucker fish, bull trout and redband trout 8 Conservation in the Upper Klamath Basin For example, all stakeholders in the Upper Klamath Basin need to identify and address social, economic, and cultural resource- based values they have historically enjoyed. Politically, there must be resolution and agreement on water rights, endangered species, and water quality. Water Conservation Because few water use measurements have been taken in the past, it is difficult to quantify where specific water efficiencies can be gained. Throughout the Upper Klamath Basin, water that leaves one irrigated field generally re- enters streams or enters the groundwater, providing the opportunity for it to be utilized again later. Because of this, water delivery systems both in and outside the USBR project area are generally efficient. As a result, the most significant benefit of reducing water demand on individual farms is an improvement in water quality and reduction in water temperatures, rather than an increase in available water. 9 Conservation in the Upper Klamath Basin Conservation measures that reduce water demand on private agricultural lands can be accomplished in a variety of ways. New technologies for managing when and where water is applied on crop and pasture lands will help to ensure that water is only applied when it is of the best benefit to the plant. Water conservation opportunities include improving irrigation water-use efficiency, retaining and conserving drainage water, and making use of new technologies that more accurately forecast the impacts of drought and floods. The subbasin assessments indicate an opportunity to conserve water and improve water quality on 130,000 acres of irrigated lands within the USBR project. Outside the project area there is an opportunity for water conservation on approximately 220,000 irrigated acres. If all potential conservation practices are implemented on all irrigated lands, on- farm water use efficiency could increase by up to 25 percent in the Upper Klamath Basin. A potential two to five percent increase in water yield could be achieved by increasing management in upland range and forestland areas. In all cases, these are preliminary estimates and require validation. This estimate does not account for evaporation, transpiration, seepage or other loses that may occur at the sites receiving conserved water nor does it evaluate irrigation delivery or conveyance efficiencies. Tupper Ansel Blake/ USFWS 10 Conservation in the Upper Klamath Basin This level of water conservation cannot be reached without a concerted federal/ state/ private partnership that works together to apply water conservation practices in targeted areas throughout the Upper Klamath Basin. Improving Water Quality Water quality has a direct impact on many fish and wildlife species. Within the Upper Klamath Basin, most rivers and lakes do not meet federally mandated Clean Water Act standards for temperature, dissolved oxygen, pH, or other pollutants. Water quality is affected by water temperature, low in- stream flows and the condition of adjacent land riparian areas, among other items. Private landowners are just one of many groups who have an opportunity to improve water quality throughout the basin. Water quality improvement opportunities on private agricultural lands in the basin range from improving the management of livestock near streams and rivers to utilizing new technologies that track pest and weed cycles to ensure that pesticides are only applied when they will be most effective. Water conservation practices that reduce tailwater runoff from irrigated fields can provide extensive improvements in water quality. 11 Conservation in the Upper Klamath Basin Increasing Water Storage/ Yield In recent years, drought has been a large contributing factor to reduced water levels in the Upper Klamath Basin. One solution to address low water flows would be to store water for times of water shortage. There are at least two challenges to this solution: finding a place to store water and finding water to store. To evaluate this option, potential storage values were calculated for 41 years of record from 1961 to 2002. This analysis reinforced the observation that, as has been seen in recent years, drought years normally occur in a multi- year cycle. Because of this, in the years where extra water is most needed, it is often not available from previous years to store. One promising, small- scale, water storage solution may lie in subsurface irrigation water storage in suitable locations, such as the Tulelake Subbasin. In this scenario, there exists a potential to store water in the soil profile and reduce irrigation water demand during the irrigation season. Another option for subsurface storage of water includes the restoration of streams and their surrounding wetlands and riparian areas. This can increase the “ sponge” effect allowing for the slow release of water through the long, dry summer months. Tupper Ansel Blake/ USFWS 12 Conservation in the Upper Klamath Basin Enhancing Fish and Wildlife Habitat The Upper Klamath Basin is home to a wide variety of aquatic and terrestrial species of wildlife and fish. Much of the water used in the Klamath wildlife refuges and associated marshes, ponds, streams and wetlands originates in the Upper Klamath Lake Subbasin. The Klamath Basin wildlife refuges provide a stopover for 85 percent of the ducks, geese, and other birds that migrate through the Pacific Flyway from Alaska to South America. Streams in the Upper Klamath Basin provide spawning and rearing habitat to threatened and endangered suckers and bull trout, as well as redband trout, which is listed as a species of concern by the US Fish and Wildlife Service. Several streams are highly valued “ catch and release” sport fisheries. There is high landowner and public interest in restoring and maintaining riparian habitat along these streams. Many of the conservation opportunities outlined under water conservation and water quality provide direct benefits to fish and wildlife as well. In addition, creating and restoring wetland areas, planting trees and developing wildlife habitat along the edges of crop fields all contribute to enhancing wildlife habitat in the basin. Tupper Ansel Blake/ USFWS 13 Conservation in the Upper Klamath Basin Overview of Conservation Effectiveness In order for the Upper Klamath Basin to successfully move forward with solutions, agriculturists, environmentalists, Tribes, government agencies, organizations, and others need to develop unified leadership to arrive at a common vision for the future. In addition, stakeholders and others must commit to a long- term investment of public and private funding as well as other resources. Based on the Upper Klamath Basin Rapid Subbasin Assessments, the Oregon and California NRCS planning staff rated the potential benefit of recommended conservation practices and resource management systems based on the conservation districts’ four resource priorities. Many state and federal agencies have invested in conservation work throughout the basin. While the recommendations in this document focus on private land and agriculture, the assessments can also be applied to help prioritize conservation practices on other land uses basin- wide. Overall, based on the planning team’s analysis, conservation activities in the Sprague River Subbasin would produce the greatest benefit, and conservation practices in the Upper Klamath River East Subbasin would yield the least Tupper Ansel Blake/ USFWS overall benefit based on the conservation district’s priorities. 14 Conservation in the Upper Klamath Basin While recognizing that any science- based conservation focus in the Upper Klamath Basin would be beneficial, the charts on pages 18- 19 specifically focus on work that can be accomplished on private lands. They provide a breakdown of recommended conservation practices on each of the conservation districts’ priorities by subbasin. For example, the water demand chart shows that investing in conservation practices in the Sprague River Subbasin has the greatest potential for reducing agriculture’s water demand by implementing improved irrigation practices. The Sprague also provides the best opportunity to address water quality and wildlife habitat. Investment in conservation activities in the Tulelake and the Upper Klamath Lake subbasins offers the greatest potential to address water storage/ yield. Investing in Conservation: Enabling farmers, ranchers and other private land managers to successfully address the four resource priorities will require: • The adoption of conservation on 350,000 acres of private farmland, range, and forests, • Financial resources estimated at $ 200 million for installation and another $ 27 million annually to operate, and • Twenty or more years to complete with the current financial and technical resources available.

Based on research completed by NRCS planning staff, the greatest potential to reduce water demand exists by implementing irrigation and riparian/ wetland conservation practices in the Sprague Subbasin. This is followed by implementing agronomic and irrigation conservation practices in Tulelake. There is no measurable water demand benefit achieved by implementing conservation practices in the Upper Klamath River East Subbasin. Comparative Benefit: Water Quality The chart at left provides an overview of the comparative benefit by subbasin of various conservation practices that improve water quality. Based on research completed by NRCS planning staff, the greatest potential to improve water quality occurs when riparian/ wetland, grazing and irrigation conservation practices are implemented in the Sprague Subbasin. In comparison, no measurable water quality benefits are achieved by implementing conservation practices in Butte Valley or the Upper Klamath River East subbasins.

Based on research completed by NRCS planning staff, the greatest potential to enhance water storage and yield occurs by implementing riparian/ wetland, forest and range conservation practices in the Upper Klamath Lake Subbasin. In comparison, the Tulelake Subbasin gains water yield through agronomic practices like subsurface drains to allow for winter irrigation. Overall, implementing forest and range practices in most subbasins will result in greater water yield within the soil profile and water table. Comparative Benefit: Habitat/ Fish Survival The chart at right provides an overview of the comparative benefit by subbasin of various conservation practices that improve wildlife habitat and fish survival. Based on research completed by NRCS planning staff, the greatest potential to improve habitat is in the Sprague Subbasin, using wetland/ riparian, forest, range and irrigation practices. In comparison, no measurable habitat benefits are achieved by implementing additional conservation practices in the Middle Lost River, Tulelake, Butte Valley or Upper Klamath River subbasins. Conservation in the Upper Klamath Basin 17 Tim McCabe/ NRCS 18 The Sprague River Subbasin is located 25 miles northeast of Klamath Falls and covers approximately 1.02 million acres. Forested mountain ridges enclose the Sprague River Valley, which includes large marshes, meadows and irrigated pasture. Juniper and sagebrush steppes dominate rangeland. Irrigated Pasture is the predominant land use in the Sprague River Valley. Approximately 65 percent of the water used for irrigation is diverted from streams, and 35 percent is pumped from wells. Flooding is the most common form of irrigation. Most diversions do not have fish screens and lack devices to measure water deliveries. Overall irrigation application efficiencies are low. Private forest and rangelands in the Sprague River subbasin are generally used for livestock grazing. Most forest stands are significantly overstocked with trees, and rangeland has been heavily encroached by Western Juniper. Pasture condition is generally poor to fair. The riparian areas within pastures have little to no riparian vegetation and high, eroding banks. Wildlife habitat in most of the upper reaches of the Sprague River and its major tributaries appears to be fairly stable, indicating good watershed condition. However, there are considerable habitat improvements that can be made in the lower portion of the basin. Sprague River Subbasin Water & Wetlands: 2,949 Range: 137,869 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 240,050 Sprague River Subbasin Agricultural Land Use/ Cover 19 Resource Concerns Water quality is the major resource concern in the Sprague River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. Lost River and shortnose suckers, interior redband and bull trout are key fish species present in the subbasin. All species are listed as Endangered Species Act threatened, candidate, or species of concern. The Sprague River has been identified as an important stream for both spawning and rearing habitat for suckers. Loss of riparian habitat, fish entrapment and fish migration impediments have also been identified as resource concerns in the Sprague River Subbasin. Conservation Accomplishments In the Sprague River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved the condition of 2,153 acres of grazing land, improved irrigation water management on 903 acres of irrigated land, and have restored 1,644 acres of riparian and wetlands areas. Fencing and riparian area restoration has been initiated or installed by private land managers with assistance from NRCS, US Fish & Wildlife Service and others on approximately 50 miles of stream and several thousand additional riparian and wetland acres. Sprague River Subbasin Land Ownership Private Lands 448,200 Public Lands 573,100 Total Land Area: 1,021,300 Irrigated Acres USBR Project: 0 Non- USBR: 61,600 Total: 61,600 20 Conservation Opportunities Water Quality & Wildlife Habitat: Riparian restoration can be accomplished by converting pastures to permanent riparian wildlife lands or establishing riparian vegetation. Riparian pasture units should be managed as a part of an overall grazing plan with cross- fencing and off- stream water for livestock. Forest stands should be managed to ensure optimum health of both the trees and grazed understory. Thinning overstocked trees and controlling juniper on rangelands are both effective management opportunities. Water Demand: Irrigation water management, including measuring water use and scheduling irrigation will help managers to maintain base river flows through late summer and early fall. Efficiencies can also be gained by leveling land, lining or piping irrigation ditches and incorporating tailwater recovery systems. Conversion from flood to sprinkler irrigation is also beneficial.

Combined, the Williamson and Sprague River subbasins make up 79 percent of the lake’s total drainage area. The Winema National Forest and Klamath Falls National Wildlife Refuge account for most of the public land in the subbasin. Irrigated pasture is the dominant private agricultural land use. Pasture is almost entirely flood irrigated. Ninety percent is diverted from streams, while groundwater supplies ten percent. Most diversions do not have fish screens and lack devices to measure water deliveries. Although overall irrigation application efficiency is low, additional water in the water table helps to subirrigate pastures. In addition, the proximity of these pastures to rivers and streams allows most excess diverted water to return to the system for reuse. Private forest and rangelands make up most of the private land in the basin. Approximately 80 percent of forestlands are used for grazing. Private forestland is in poor to fair condition; over half of the stands are significantly overstocked with trees. Wildlife habitat has faced considerable degradation in the past. Of the 48 miles of stream that are degraded in the subbasin, restoration efforts have been initiated on approximately 23 miles. Williamson River Subbasin Water & Wetlands: 19,700 Range: 2,600 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 225,300 Williamson River Subbasin Agricultural Land Use/ Cover Irrigated Alfalfa: 1,100 23 Water quality relating to elevated stream temperatures is a major resource concern in the Williamson River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. In 1988, when the Lost River and Shortnose suckers were listed as endangered, the Williamson and Sprague River runs were estimated to have declined by as much as 95 percent during the previous twenty- year period. Important sucker habitat has diminished by nearly 50 percent in the lower reaches and near the mouth of the Williamson River. This has reduced the amount of larval sucker spawning and rearing habitat. Conservation Accomplishments Significant conservation progress has been made in this subbasin. Land managers have improved 500 acres of grazing lands, 1,000 acres of irrigated lands, 235 acres of forestlands and have restored 112 acres of riparian and wetland areas. Heightened landowner awareness of resource concerns and increasing agency, organization, and individual efforts will help this trend to continue. Of the 48 miles of stream that are degraded in the subbasin, private land managers are working with the US Fish and Wildlife Service and others to restore 23 miles. The Nature Conservancy is restoring approximately 3,200 acres of wetlands, and plans to restore another 3,411 acres at the mouth of the Williamson River.

This can be accomplished by converting lands from irrigated agriculture to wildlife habitat or creating riparian pasture systems. Wetland and riparian areas still utilize water. However, this work may reduce total water demand depending on how lands are managed. Water Demand: Thinning forest stands and managing grazing areas by adding cross fences and off- stream water for livestock can yield more water to meet downstream needs. This will also result in enhanced wildlife habitat and improved water quality in area streams. In addition, forest stand improvements reduce the potential for catastrophic fire.

Historically, some 43,000 acres of wetlands surrounded Agency and Upper Klamath Lake. Today, 17,000 acres have been preserved as part of the Upper Klamath Lake National Wildlife Refuge. Another 11,000 acres have been acquired for restoration. Irrigated agriculture is primarily pasture. Livestock are generally stocker cattle, who graze between April and November. Pasture condition is generally fair. Most livestock obtain water from streams and ditches. Irrigation water is diverted from streams or pumped from the lake. Most diversions do not have fish screens or devices to measure water. Although overall irrigation application efficiency is low, the additional water raises the water table and subirrigated pastures. Some acreages of hay and cereal crops are grown, and irrigation efficiencies are higher than for pasture. However, most require maintenance and re- leveling. Forestlands are primarily pine and mixed fir and hemlock. Most private lands in the subbasin are forest or rangelands, with approximately 80 percent used for grazing. More than half of the forest stands are significantly overstocked with trees. Wildlife habitat varies in condition. Of 70 total miles, 21 miles of streamside riparian areas are in good condition and another 12 miles are being restored. Upper Klamath Lake Subbasin Water & Wetlands: 76,568 Range: 2,404 Irrigated Pasture/ Grass Hay: 48,856 Forest/ Mixed: 100,311 Upper Klamath Lake Subbasin Agricultural Land Use/ Cover Irrigated Crop/ Alfalfa: 3,396 27 Resource Concerns Water quality in the Upper Klamath Lake is a major resource concern, affecting subbasin fish survival, with phosphorus loading as the greatest factor. The loss of wetland vegetation around the lake has also been linked to lower survival rates for endangered suckers. The lower reaches of the Wood River and Sevenmile Creek provide some rearing habitat for larval and juvenile suckers. The Wood River, Sevenmile Creek and their tributaries support populations of bull and interior redband trout. A highly valued “ catch and release” sport fishery occurs on the Wood River and several of its tributaries. There is significant interest in enhancing riparian habitat along these streams to protect and promote these fisheries. Conservation Accomplishments In the Upper Klamath Lake Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved 12 acres of grazing lands and improved water quality and quantity on 12 acres of irrigated land. Several thousand more acres of wetland restoration are in the process of being planned or implemented around Upper Klamath Lake.

This can be accomplished by either converting pastures to permanent wildlife habitat or by creating riparian pastures. While most pastures are being inefficiently irrigated, conditions do not warrant extensive changes from current flood irrigation systems since water is reused or enters the soil profile Water Storage: In the Upper Klamath Lake Subbasin, the potential for non- traditional water storage presents a unique conservation opportunity. Restoring drained wetlands, still farmed around Upper Klamath Lake, could produce positive benefits for all four resource concerns. By actively managing areas for both seasonal wetlands and farming, water can be both filtered to improve water quality and stored in wetland areas for future use.

The valley once supported a vast network of wet meadows and marshes. This subbasin covers approximately 1.2 million acres and is split from the Middle Lost River Subbasin near Olene. Irrigated agriculture generally occurs in the warmer valleys. Flood is the most common pasture irrigation method, with about 50 percent of the water coming from the USBR project. Pasture condition is fair, and most pastures have not been renovated or re- leveled for some time. Maintenance would increase the efficiencies of 60 to 80 percent of the systems. Alfalfa is customarily sprinkler- irrigated and well- managed. Although irrigation efficiencies are higher than for pasture, many sprinkler systems still need upgrading. Several irrigated crops are grown in the subbasin including cereal grains, potatoes, and strawberry plants. Forestland, range and pasture are grazed by livestock. Rangelands are comprised of juniper and sagebrush steppes. Forestlands are generally mixed conifer. Livestock operations include cow/ calf, stockers and dairies. Confined livestock operations are located throughout the subbasin. The location and duration of confinement may pose a potential risk to water quality. Seven dairies located within the subbasin have existing liquid and dry livestock waste storage facilities.

High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving over the last 10 to 20 years. While agriculture is the dominant land use in this subbasin, other sources of phosphorus and other pollutants exist. Sewage treatment outfalls, on- site sewage disposal systems, wildlife, and natural inputs also contribute nutrients and other pollutants to the system. While historically the river had significant fish runs, it currently supports only a small population of Shortnose and Lost River suckers. Conservation Accomplishments In the Upper Lost River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved resource conditions on 234 acres of croplands and 5,282 acres of grazing lands, and have improved their management of irrigation water on 5,596 acres of irrigated lands. In addition, 846 acres of riparian and wetland areas have been restored.

On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops. Implementing practices like diverting clean water before it flows through livestock confinement areas near water sources, will reduce the risk of polluted runoff. Water Demand: On both surface-irrigated pastures and cropland areas, there are opportunities for land leveling or smoothing, lining or piping irrigation delivery ditches, upgrading irrigation systems and developing tailwater recovery systems to improve water use efficiency.

Farms near Klamath Falls tend to be smaller, indicating part- time or hobby operations. The area includes 12 irrigation districts and leased lands on the Lower Klamath Wildlife Refuge that receive water supplied by the USBR Klamath Project. Public lands include the refuge, and parts of Modoc and Klamath national forests. Irrigated agriculture includes pasture, alfalfa, cereal grain, potatoes, onions and mint. Roughly 70 percent is irrigated with USBR- supplied water; the rest is obtained from groundwater, individual surface water rights or special USBR contracts. Many fields are either flood or sprinkler irrigated depending on the year and crop. Most farm irrigation diversions lack a means to measure water delivery. Livestock operations include several dairies and cattle feeding operations. Substantial range acreage is used for livestock grazing. Pasture condition is fair and most pastures have not been renovated or re- leveled for some time. Pastures associated with smaller livestock operations in and around Klamath Falls appear to be in the most need of improved pastures and irrigation systems. Wildlife habitat: Ten river miles are in relatively good riparian condition given the river is used for conveying irrigation water. Some 13 miles of stream lack adequate riparian vegetation and streambank protection.

Drought conditions and increased competition for available water have increased economic, social, political and environmental concerns and uncertainty over the future. Habitat and water quality are two additional major resource concerns in the subbasin. High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other pollutant sources exist. While the river had significant historic fish runs, it currently supports only a small sucker population. Conservation Accomplishments In the last two years, the Middle Lost River Subbasin has seen significant conservation progress. With assistance from NRCS and local conservation districts, land managers have improved the condition of natural resources on 489 acres of cropland and 3,521 grazing land acres. In addition, 564 acres of riparian and wetland areas have been restored, and water use efficiency has been increased on 3,731 acres of irrigated lands.

Highly effective conservation measures on hay and cropland should focus on updating existing irrigation systems and improving irrigation water management. Water Quality: The use of grazing systems that rotate livestock through smaller pastures will increase forage production, reduce soil compaction and improve water quality. While fishery benefits from restoring riparian areas are minimal, streamside buffers will improve water quality and provide habitat for other wildlife. On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops.

The Tulelake Irrigation District and the Tulelake National Wildlife Refuge receive water from the USBR Klamath Project. Tulelake is a remnant of historic Lake Modoc that once connected the subbasin with both Lower and Upper Klamath Lake. The Lost River watershed was once a closed basin. Runoff flowed into Tulelake and evaporated. Pumping plants and drains constructed as a part of the project have provided an outlet from Tulelake, which now functions as an open basin. Irrigated agriculture is generally supplied by the USBR. Alfalfa, grain, potatoes, onions, mint and pasture are the principal crops. Fields are flood or sprinkler irrigated depending on the year and crop. Often diversions lack devices to measure water delivery. Pasture condition is fair, and most have not been renovated for some time. Groundwater provides 40- 50 percent of water for irrigated pastures, and most excess water is reused. Rangeland is the other significant land use. Most ranches are cow/ calf operations that have winter holdings in the subbasin. Rangelands are generally encroached with juniper. Wildlife habitat along the Lost River has reeds and bullrush, providing some habitat for waterfowl and songbirds. Suckers have been located in the river and Tulelake; however, it is not known whether they are successfully reproducing. There are few opportunities to improve habitat along this heavily manipulated reach of the river.

Irrigators depend on water- use decisions made by fellow irrigators and resource managers for their irrigation needs. Drought and increased competition for water leads to the primary resource concern in the basin - a reliable supply of water to meet agriculture, wildlife and other resource needs. Water quality deteriorates as it moves through the USBR project. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other sources of phosphorus and other pollutants exist. The presence of ESA- listed suckers creates concerns for improving habitat and water quality. The two national wildlife refuges support large waterfowl populations. Farmland on the refuges is leased to farmers to supply grain for waterfowl and shorebirds. These populations depend on refuges, leased lands and adjacent farms during the fall and spring migratory periods. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Tulelake Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, local land managers have improved the condition of natural resources on 72 cropland acres and 1,854 irrigated land acres, and have restored 21 acres of riparian and wetland areas.

Subsurface drainage could be added before re- establishing alfalfa stands, permitting better control of water table and soil moisture levels. During years that alfalfa fields are rotated to grain, winter flooding or pre- season irrigation could be used to reduce water demand. Water Storage/ Yield: Adding subsurface drainage may be the most significant practice to implement on cropland acres. Subsurface drains would allow farmers to winter flood or pre-irrigate fields, thereby reducing their demand for water during the irrigation season. If pre- irrigated, farmers could grow a cereal crop even if water deliveries are cut off during drought years. In addition, juniper control on rangelands will yield additional water to meet downstream needs.

While part of the Upper Klamath Basin, it is an internal drainage basin with only an artificial outlet. Groundwater flows from west to east out of the subbasin under the Mahogany Mountains toward the lake. A channel and pump plant were built to remove floodwaters. This channel is used infrequently and for only short durations. The Klamath National Forest, Butte Valley National Grassland, and the Butte Valley Wildlife Area make up the majority of the public lands. Irrigated agriculture includes alfalfa hay as the predominate crop. Cereal grains, potatoes and strawberry plants are also grown. Crops are usually sprinkler irrigated, and sprinklers are well maintained. Few irrigators measure water applied or schedule irrigation. Cattle operations graze irrigated pastures and meadows scattered throughout the subbasin along with range and forestlands. Pastures are generally flood irrigated and are supplied by streams. Most farm irrigation diversions lack water measuring devices. Mixed conifer forests are found at higher elevations and are generally operated as industrial forests. Range sites are dominated by Western Juniper and are generally in poor condition. Wildlife habitat is generally wetlands in the state wildlife refuge or on national grasslands. Approximately 26 miles of streams on private lands have inadequate riparian vegetation.

Generally, streams in the upper portions of the subbasin support good populations of Brown and Rainbow trout. The Tulelake National Wildlife Refuge and Lower Klamath Lake National Wildlife Refuge support large populations of migratory and permanent waterfowl. Farmland on the refuges is leased to area farmers to supply grain for the waterfowl and shorebirds. The large bird populations depend on the refuges, leased lands and adjacent farms throughout the fall and spring migratory periods for habitat. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Butte Valley Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, local land managers have restored 27 acres of riparian and wetland areas in the last two years.

Other than limited contributions to groundwater in the Upper Klamath Basin, reductions in water demand only benefit the subbasin. Sprinkler- irrigated hay, cereal crops and row crops dominate land use on the better soils. Highly effective conservation on hay and cropland should focus on improving the overall irrigation efficiency of existing systems. This can be accomplished by upgrading systems and scheduling irrigation. An estimated 40 percent of the existing systems would benefit from maintenance. On controlled flood irrigated pastures, there are opportunities for land leveling or smoothing, lining or piping delivery ditches, and recovering tailwater. Additional water savings and water quality benefits could be gained by converting existing surface irrigation to sprinklers if power is available and affordable. On rangelands, juniper control and improved grazing management are the primary conservation opportunities.

Nearly half of the area is in public ownership. Iron Gate and Copco reservoirs are used extensively for recreational fishing, boating and camping. Whitewater rafting and kayaking are popular below the KC Boyle Dam. The KC Boyle, Copco and Iron Gate dams are used and regulated for power generation. Irrigated agriculture occurs on only 4,000 acres of pasture. Only a few isolated ranches are located in this subbasin. Cattle operations rotate grazing of irrigated pastures with significant acreage of grazed range and forest. Pastures are surface irrigated with a mix of controlled and flood irrigation. All irrigation water is diverted from the river or tributary streams. Most farm irrigation diversions lack devices to measure water. Even though overall irrigation application efficiency is low, the proximity of irrigated pastures to the river allows most excess water diverted to be reused downstream. Private forest and rangelands make up most of the private land, nearly all of which is used for livestock grazing. Much of the rangeland is in poor condition, with heavy juniper encroachment. More than half of the forest stands are overstocked with trees. Wildlife habitat along riparian areas is generally in good condition. Of the 12 miles of riparian areas surveyed, five would benefit from some restoration.

Water withdrawals are insignificant along this stretch of the river. Salmon and steelhead are blocked at Iron Gate Dam from upstream passage. Several resident trout species exist, supporting a recreational fishery. Conservation Accomplishments In the Klamath River East Subbasin during the last two years, some conservation progress has been made.

Natural Resources Conservation Service Year: 2004, 2005 1 i California Oregon Cover Photo: Lower Klamath National Wildlife Refuge at sunset Tupper Ansel Blake/ USFWS Map Detail Area: Upper Klamath River Basin ii T he Klamath River Basin presents numerous challenges as well as opportunities for its many water users. For years, farmers and ranchers in the basin have recognized the vital role they play in the health of their watershed. Working with conservation districts, the Natural Resources Conservation Service ( NRCS) and others, land managers continue to proactively find ways to enhance natural resources in the basin, benefiting wildlife and the environment. However, as it has across the western United States, drought hit home in the Klamath for those who depend on every drop of water to sustain their livelihood, culture and community. In the spring of 2001, the combination of drought and the impact of the Endangered Species Act triggered a shutdown of irrigation water during the growing season, drying up water resources to more than 2,000 farms and ranches. NRCS, in cooperation with local conservation districts, provided a quick infusion of technical assistance and $ 2 million in cost- share funding for cover crops through the Emergency Watershed Protection Program. As cover crops took hold, the seeds of a long- term solution took root in the NRCS/ conservation district partnership. The ability of the local office to receive funding, engage community members and other partners, plan resource improvements, implement actions, and monitor success proved to be an invaluable asset for the community. Helping private landowners develop and apply practical, common- sense solutions to complex resource issues will be the challenge of the conservation partnership well into the future. USDA, in concert with the locally led conservation districts, will continue to play a critical role by delivering technical and financial assistance to Klamath Basin farmers and ranchers. The Rapid Subbasin Assessments that follow are the first step in that process. The assessments are designed to help local decision- makers determine where investments in conservation will best benefit wildlife habitat, agriculture and other land uses in a compatible manner. It is our goal to provide a comprehensive overview of resource challenges and opportunities in the basin, and help decision- makers to prioritize their investments in areas that will best sustain multiple use of natural resources in the basin now and in the future.

Stretching across southern Oregon and northern California, the Klamath Basin has become synonymous with the water challenges that western water users face. As one example, agricultural commodities that need irrigation water to thrive – providing Americans with the cheapest domestic food supply in the world, face competition from the critical water needs of sucker fish, salmon and other threatened and endangered species. While that competition is understandable, more and more, conservation leaders in all industries have come to recognize that these water needs aren’t necessarily at odds with one another, and can in fact be compatible. While an example of the challenges today’s agricultural producers and conservationists face, the Klamath Basin has emerged as an example of how diverse interests can work together successfully. 2 Overview of the Upper Klamath Basin Upper Klamath Basin Description The Upper Klamath Basin is an area of high desert, wetlands, and the Klamath River. The river extends 250 miles from its headwaters at Upper Klamath Lake in south central Oregon to the west coast of northern California. The Upper Klamath Basin includes the US Bureau of Reclamation’s ( USBR) Klamath Project Area and the drainage area above Irongate Dam on the Klamath River. The basin’s lakes, marshes, and wetlands host an abundance of plant and animal species and include national wildlife refuges, parks, and forests. Agricultural production began around the turn of the 20th century, and with the creation of the Klamath Irrigation District in 1905, water diversions for irrigation began in earnest. A portion of these irrigated lands are in the USBR’s irrigation project. The ‘ project area,’ as it is commonly called, includes 188,000 of the 502,000 acres of private irrigated land in the basin. This includes lands leased from the various wildlife refuges that are supplied with water by the USBR. Privately irrigated acreages can vary from year to year, depending on USBR contracts and annual cropping cycles. In comparison, the majority of the private irrigated land - about 314,000 acres - in the basin is located outside the project area. Upper Klamath Basin Quick Facts: • Over 2.2 million acres are privately owned in the Upper Klamath Basin • 188,000 of the irrigated acres are in the US Bureau of Reclamation’s Irrigation Project • Approximately 502,000 acres of privately owned lands are irrigated • 314,000 acres of irrigated lands are outside the Project area 3 Overview of the Upper Klamath Basin The Role of Agriculture in the Basin Agricultural lands play a key role in a healthy ecosystem. Located on the Pacific Flyway, migratory birds like the American White Pelican and the Red- Necked Grebe use croplands in the Klamath Basin as an important feeding and resting stop. Deer graze on wheat and barley fields, and pheasants use both crop and rangelands for their nesting and feeding grounds. Progressive conservation leaders recognize that farming and fish and wildlife habitat are not mutually exclusive. Well- maintained farmland creates fish and wildlife habitat, contributing to a healthy watershed. They also recognize that opportunities will always exist to improve the condition of natural resources in the basin. To address those opportunities, conservation leaders in Oregon’s Klamath Falls Soil and Water Conservation District and California’s Lava Beds/ Butte Valley Resource Conservation District have proactively identified four key priorities tied to natural resource conservation. The districts asked experts at the USDA’s Natural Resources Conservation Service to help them develop a plan to determine what could be done on- farm to conserve water, increase water storage, improve water quality, and enhance fish and wildlife habitat. While so much of the attention to date in the Klamath Basin has been focused on water demand, these conservation leaders recognize demand is only one piece of the puzzle. Comprehensive solutions must also address water quality, storage and wildlife habitat. Conservation District Priorities 1) Conserve Water 2) Increase Water Storage 3) Improve Water Quality 4) Enhance Fish & Wildlife Habitat 4 Rapid Subbasin Assessments Conserving natural resources is the ultimate goal throughout the basin, and its success hinges on long- term solutions. At the request of local conservation districts, NRCS undertook an 18- month study of resource concerns, challenges and opportunities throughout the Upper Klamath Basin. The study was not intended to provide a detailed, quantitative analysis of the impacts of conservation work, but rather, to provide an initial estimate of where conservation investments would best address the districts’ four priority resource concerns. Beginning in the spring of 2002, NRCS planners collected information to enable the conservation districts, agencies, organizations, farmers, ranchers and others to make informed decisions in a timely manner about conservation and resource management in the basin. These Rapid Subbasin Assessments are intended to help leaders set priorities and determine the best actions to achieve their goals. As a part of the rapid subbasin assessment process, eight subbasins were delineated ( see map at left). A watershed planning team traveled through each subbasin, inventorying agricultural areas, identifying conservation opportunities and current levels of resource management, and estimating the impacts of these opportunities on the Conservation in the Upper Klamath Basin 5 Conservation in the Upper Klamath Basin conservation districts’ priority resource concerns. They focused their recommendations on areas that would provide the best benefit to the wide array of stakeholders in the Upper Klamath Basin. They also identified a number of socio- economic factors that must be taken into consideration when helping producers adapt to new management styles and conservation activities. Through NRCS, conservation districts and other federal, state and local entities, private land managers are working to identify ways they can more efficiently use – and share – the water they need. In the face of increasingly complex and politically polarized circumstances, a clear purpose and direction has arisen. The commitment of the local conservation partnership to identify the impacts of water shortages and to find solutions that will improve natural resource conservation will be key to the long- term viability of both endangered species and industries in the Upper Klamath Basin. The information that follows provides a summary of the conservation challenges and opportunities that NRCS staff found in their assessment. Recommendations for where financial and other resources can best be invested to improve natural resources, while sustaining the economy of the Upper Klamath Basin, are also identified. 6 Conservation in the Upper Klamath Basin Private Lands Conservation Accomplishments One component necessary to understanding future conservation opportunities in the basin is to recognize the current conservation work of private land managers. An indicator of these efforts is the work that has been undertaken in partnership with NRCS and the local conservation districts. In federal fiscal years 2002 and 2003, Upper Klamath Basin farmers and ranchers improved resource conditions on 18,877 acres of privately owned agricultural lands, with assistance from NRCS and the conservation districts. During this time, private land managers have worked with the conservation districts in the basin to: • improve the condition of 11,800 acres of grazing lands • conserve water and improve water quality on 13,656 acres • restore and establish 4,138 acres of wetlands and riparian areas • improve 281 acres of forest stands • establish resource management systems on 1,351 acres of cropland These conservation efforts were accomplished with a combination of private, state and federal funding. 7 Conservation in the Upper Klamath Basin Summary of Conservation Opportunities In addition to recognizing current conservation activities, the assessments define what can be accomplished with a strong conservation partnership in the Upper Klamath Basin. All too often, the debate about multi- use of water in the basin has focused on ways to reduce water demand. However, the basin’s many water users - including fish and wildlife - benefit just as much from improvements to water quality, water storage and wildlife habitat. Taken together, the recommendations that follow seek to utilize a comprehensive approach to all four resource priorities - with the goal of contributing to a sustainable, multi- use water system. While quantification of the results of conservation work in these four areas is difficult, there is no question that a comprehensive approach to natural resource improvement in the Upper Klamath Basin will result in accumulative long- term benefits for endangered fish species, wildlife habitat, agriculture, urban and other water uses. Agriculture cannot undertake these efforts alone. Private landowners and the general public both benefit from natural resources conservation in the Upper Klamath Basin. Because of this, public and private sources of funding from in and outside the region are necessary. Solutions of this magnitude also come with other social, political, and cultural costs. Upper Klamath Basin Quick Facts: • 1,400 farm families live in the Upper Klamath Basin • The Upper Klamath Basin is home to sucker fish, bull trout and redband trout 8 Conservation in the Upper Klamath Basin For example, all stakeholders in the Upper Klamath Basin need to identify and address social, economic, and cultural resource- based values they have historically enjoyed. Politically, there must be resolution and agreement on water rights, endangered species, and water quality. Water Conservation Because few water use measurements have been taken in the past, it is difficult to quantify where specific water efficiencies can be gained. Throughout the Upper Klamath Basin, water that leaves one irrigated field generally re- enters streams or enters the groundwater, providing the opportunity for it to be utilized again later. Because of this, water delivery systems both in and outside the USBR project area are generally efficient. As a result, the most significant benefit of reducing water demand on individual farms is an improvement in water quality and reduction in water temperatures, rather than an increase in available water. 9 Conservation in the Upper Klamath Basin Conservation measures that reduce water demand on private agricultural lands can be accomplished in a variety of ways. New technologies for managing when and where water is applied on crop and pasture lands will help to ensure that water is only applied when it is of the best benefit to the plant. Water conservation opportunities include improving irrigation water-use efficiency, retaining and conserving drainage water, and making use of new technologies that more accurately forecast the impacts of drought and floods. The subbasin assessments indicate an opportunity to conserve water and improve water quality on 130,000 acres of irrigated lands within the USBR project. Outside the project area there is an opportunity for water conservation on approximately 220,000 irrigated acres. If all potential conservation practices are implemented on all irrigated lands, on- farm water use efficiency could increase by up to 25 percent in the Upper Klamath Basin. A potential two to five percent increase in water yield could be achieved by increasing management in upland range and forestland areas. In all cases, these are preliminary estimates and require validation. This estimate does not account for evaporation, transpiration, seepage or other loses that may occur at the sites receiving conserved water nor does it evaluate irrigation delivery or conveyance efficiencies. Tupper Ansel Blake/ USFWS 10 Conservation in the Upper Klamath Basin This level of water conservation cannot be reached without a concerted federal/ state/ private partnership that works together to apply water conservation practices in targeted areas throughout the Upper Klamath Basin. Improving Water Quality Water quality has a direct impact on many fish and wildlife species. Within the Upper Klamath Basin, most rivers and lakes do not meet federally mandated Clean Water Act standards for temperature, dissolved oxygen, pH, or other pollutants. Water quality is affected by water temperature, low in- stream flows and the condition of adjacent land riparian areas, among other items. Private landowners are just one of many groups who have an opportunity to improve water quality throughout the basin. Water quality improvement opportunities on private agricultural lands in the basin range from improving the management of livestock near streams and rivers to utilizing new technologies that track pest and weed cycles to ensure that pesticides are only applied when they will be most effective. Water conservation practices that reduce tailwater runoff from irrigated fields can provide extensive improvements in water quality. 11 Conservation in the Upper Klamath Basin Increasing Water Storage/ Yield In recent years, drought has been a large contributing factor to reduced water levels in the Upper Klamath Basin. One solution to address low water flows would be to store water for times of water shortage. There are at least two challenges to this solution: finding a place to store water and finding water to store. To evaluate this option, potential storage values were calculated for 41 years of record from 1961 to 2002. This analysis reinforced the observation that, as has been seen in recent years, drought years normally occur in a multi- year cycle. Because of this, in the years where extra water is most needed, it is often not available from previous years to store. One promising, small- scale, water storage solution may lie in subsurface irrigation water storage in suitable locations, such as the Tulelake Subbasin. In this scenario, there exists a potential to store water in the soil profile and reduce irrigation water demand during the irrigation season. Another option for subsurface storage of water includes the restoration of streams and their surrounding wetlands and riparian areas. This can increase the “ sponge” effect allowing for the slow release of water through the long, dry summer months. Tupper Ansel Blake/ USFWS 12 Conservation in the Upper Klamath Basin Enhancing Fish and Wildlife Habitat The Upper Klamath Basin is home to a wide variety of aquatic and terrestrial species of wildlife and fish. Much of the water used in the Klamath wildlife refuges and associated marshes, ponds, streams and wetlands originates in the Upper Klamath Lake Subbasin. The Klamath Basin wildlife refuges provide a stopover for 85 percent of the ducks, geese, and other birds that migrate through the Pacific Flyway from Alaska to South America. Streams in the Upper Klamath Basin provide spawning and rearing habitat to threatened and endangered suckers and bull trout, as well as redband trout, which is listed as a species of concern by the US Fish and Wildlife Service. Several streams are highly valued “ catch and release” sport fisheries. There is high landowner and public interest in restoring and maintaining riparian habitat along these streams. Many of the conservation opportunities outlined under water conservation and water quality provide direct benefits to fish and wildlife as well. In addition, creating and restoring wetland areas, planting trees and developing wildlife habitat along the edges of crop fields all contribute to enhancing wildlife habitat in the basin. Tupper Ansel Blake/ USFWS 13 Conservation in the Upper Klamath Basin Overview of Conservation Effectiveness In order for the Upper Klamath Basin to successfully move forward with solutions, agriculturists, environmentalists, Tribes, government agencies, organizations, and others need to develop unified leadership to arrive at a common vision for the future. In addition, stakeholders and others must commit to a long- term investment of public and private funding as well as other resources. Based on the Upper Klamath Basin Rapid Subbasin Assessments, the Oregon and California NRCS planning staff rated the potential benefit of recommended conservation practices and resource management systems based on the conservation districts’ four resource priorities. Many state and federal agencies have invested in conservation work throughout the basin. While the recommendations in this document focus on private land and agriculture, the assessments can also be applied to help prioritize conservation practices on other land uses basin- wide. Overall, based on the planning team’s analysis, conservation activities in the Sprague River Subbasin would produce the greatest benefit, and conservation practices in the Upper Klamath River East Subbasin would yield the least Tupper Ansel Blake/ USFWS overall benefit based on the conservation district’s priorities. 14 Conservation in the Upper Klamath Basin While recognizing that any science- based conservation focus in the Upper Klamath Basin would be beneficial, the charts on pages 18- 19 specifically focus on work that can be accomplished on private lands. They provide a breakdown of recommended conservation practices on each of the conservation districts’ priorities by subbasin. For example, the water demand chart shows that investing in conservation practices in the Sprague River Subbasin has the greatest potential for reducing agriculture’s water demand by implementing improved irrigation practices. The Sprague also provides the best opportunity to address water quality and wildlife habitat. Investment in conservation activities in the Tulelake and the Upper Klamath Lake subbasins offers the greatest potential to address water storage/ yield. Investing in Conservation: Enabling farmers, ranchers and other private land managers to successfully address the four resource priorities will require: • The adoption of conservation on 350,000 acres of private farmland, range, and forests, • Financial resources estimated at $ 200 million for installation and another $ 27 million annually to operate, and • Twenty or more years to complete with the current financial and technical resources available.

This is followed by implementing agronomic and irrigation conservation practices in Tulelake. There is no measurable water demand benefit achieved by implementing conservation practices in the Upper Klamath River East Subbasin. Comparative Benefit: Water Quality The chart at left provides an overview of the comparative benefit by subbasin of various conservation practices that improve water quality. Based on research completed by NRCS planning staff, the greatest potential to improve water quality occurs when riparian/ wetland, grazing and irrigation conservation practices are implemented in the Sprague Subbasin. In comparison, no measurable water quality benefits are achieved by implementing conservation practices in Butte Valley or the Upper Klamath River East subbasins.

Based on research completed by NRCS planning staff, the greatest potential to enhance water storage and yield occurs by implementing riparian/ wetland, forest and range conservation practices in the Upper Klamath Lake Subbasin. In comparison, the Tulelake Subbasin gains water yield through agronomic practices like subsurface drains to allow for winter irrigation. Overall, implementing forest and range practices in most subbasins will result in greater water yield within the soil profile and water table. Comparative Benefit: Habitat/ Fish Survival The chart at right provides an overview of the comparative benefit by subbasin of various conservation practices that improve wildlife habitat and fish survival. Based on research completed by NRCS planning staff, the greatest potential to improve habitat is in the Sprague Subbasin, using wetland/ riparian, forest, range and irrigation practices. In comparison, no measurable habitat benefits are achieved by implementing additional conservation practices in the Middle Lost River, Tulelake, Butte Valley or Upper Klamath River subbasins. Conservation in the Upper Klamath Basin 17 Tim McCabe/ NRCS 18 The Sprague River Subbasin is located 25 miles northeast of Klamath Falls and covers approximately 1.02 million acres. Forested mountain ridges enclose the Sprague River Valley, which includes large marshes, meadows and irrigated pasture. Juniper and sagebrush steppes dominate rangeland. Irrigated Pasture is the predominant land use in the Sprague River Valley. Approximately 65 percent of the water used for irrigation is diverted from streams, and 35 percent is pumped from wells. Flooding is the most common form of irrigation. Most diversions do not have fish screens and lack devices to measure water deliveries. Overall irrigation application efficiencies are low. Private forest and rangelands in the Sprague River subbasin are generally used for livestock grazing. Most forest stands are significantly overstocked with trees, and rangeland has been heavily encroached by Western Juniper. Pasture condition is generally poor to fair. The riparian areas within pastures have little to no riparian vegetation and high, eroding banks. Wildlife habitat in most of the upper reaches of the Sprague River and its major tributaries appears to be fairly stable, indicating good watershed condition. However, there are considerable habitat improvements that can be made in the lower portion of the basin. Sprague River Subbasin Water & Wetlands: 2,949 Range: 137,869 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 240,050 Sprague River Subbasin Agricultural Land Use/ Cover 19 Resource Concerns Water quality is the major resource concern in the Sprague River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. Lost River and shortnose suckers, interior redband and bull trout are key fish species present in the subbasin. All species are listed as Endangered Species Act threatened, candidate, or species of concern. The Sprague River has been identified as an important stream for both spawning and rearing habitat for suckers. Loss of riparian habitat, fish entrapment and fish migration impediments have also been identified as resource concerns in the Sprague River Subbasin. Conservation Accomplishments In the Sprague River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved the condition of 2,153 acres of grazing land, improved irrigation water management on 903 acres of irrigated land, and have restored 1,644 acres of riparian and wetlands areas. Fencing and riparian area restoration has been initiated or installed by private land managers with assistance from NRCS, US Fish & Wildlife Service and others on approximately 50 miles of stream and several thousand additional riparian and wetland acres. Sprague River Subbasin Land Ownership Private Lands 448,200 Public Lands 573,100 Total Land Area: 1,021,300 Irrigated Acres USBR Project: 0 Non- USBR: 61,600 Total: 61,600 20 Conservation Opportunities Water Quality & Wildlife Habitat: Riparian restoration can be accomplished by converting pastures to permanent riparian wildlife lands or establishing riparian vegetation. Riparian pasture units should be managed as a part of an overall grazing plan with cross- fencing and off- stream water for livestock. Forest stands should be managed to ensure optimum health of both the trees and grazed understory. Thinning overstocked trees and controlling juniper on rangelands are both effective management opportunities. Water Demand: Irrigation water management, including measuring water use and scheduling irrigation will help managers to maintain base river flows through late summer and early fall. Efficiencies can also be gained by leveling land, lining or piping irrigation ditches and incorporating tailwater recovery systems. Conversion from flood to sprinkler irrigation is also beneficial.

Combined, the Williamson and Sprague River subbasins make up 79 percent of the lake’s total drainage area. The Winema National Forest and Klamath Falls National Wildlife Refuge account for most of the public land in the subbasin. Irrigated pasture is the dominant private agricultural land use. Pasture is almost entirely flood irrigated. Ninety percent is diverted from streams, while groundwater supplies ten percent. Most diversions do not have fish screens and lack devices to measure water deliveries. Although overall irrigation application efficiency is low, additional water in the water table helps to subirrigate pastures. In addition, the proximity of these pastures to rivers and streams allows most excess diverted water to return to the system for reuse. Private forest and rangelands make up most of the private land in the basin. Approximately 80 percent of forestlands are used for grazing. Private forestland is in poor to fair condition; over half of the stands are significantly overstocked with trees. Wildlife habitat has faced considerable degradation in the past. Of the 48 miles of stream that are degraded in the subbasin, restoration efforts have been initiated on approximately 23 miles. Williamson River Subbasin Water & Wetlands: 19,700 Range: 2,600 Irrigated Pasture/ Grass Hay: 81,650 Forest/ Mixed: 225,300 Williamson River Subbasin Agricultural Land Use/ Cover Irrigated Alfalfa: 1,100 23 Water quality relating to elevated stream temperatures is a major resource concern in the Williamson River Subbasin, directly impacting fish and wildlife habitat throughout the Upper Klamath Basin. In 1988, when the Lost River and Shortnose suckers were listed as endangered, the Williamson and Sprague River runs were estimated to have declined by as much as 95 percent during the previous twenty- year period. Important sucker habitat has diminished by nearly 50 percent in the lower reaches and near the mouth of the Williamson River. This has reduced the amount of larval sucker spawning and rearing habitat. Conservation Accomplishments Significant conservation progress has been made in this subbasin. Land managers have improved 500 acres of grazing lands, 1,000 acres of irrigated lands, 235 acres of forestlands and have restored 112 acres of riparian and wetland areas. Heightened landowner awareness of resource concerns and increasing agency, organization, and individual efforts will help this trend to continue. Of the 48 miles of stream that are degraded in the subbasin, private land managers are working with the US Fish and Wildlife Service and others to restore 23 miles. The Nature Conservancy is restoring approximately 3,200 acres of wetlands, and plans to restore another 3,411 acres at the mouth of the Williamson River.

This can be accomplished by converting lands from irrigated agriculture to wildlife habitat or creating riparian pasture systems. Wetland and riparian areas still utilize water. However, this work may reduce total water demand depending on how lands are managed. Water Demand: Thinning forest stands and managing grazing areas by adding cross fences and off- stream water for livestock can yield more water to meet downstream needs. This will also result in enhanced wildlife habitat and improved water quality in area streams. In addition, forest stand improvements reduce the potential for catastrophic fire.

Historically, some 43,000 acres of wetlands surrounded Agency and Upper Klamath Lake. Today, 17,000 acres have been preserved as part of the Upper Klamath Lake National Wildlife Refuge. Another 11,000 acres have been acquired for restoration. Irrigated agriculture is primarily pasture. Livestock are generally stocker cattle, who graze between April and November. Pasture condition is generally fair. Most livestock obtain water from streams and ditches. Irrigation water is diverted from streams or pumped from the lake. Most diversions do not have fish screens or devices to measure water. Although overall irrigation application efficiency is low, the additional water raises the water table and subirrigated pastures. Some acreages of hay and cereal crops are grown, and irrigation efficiencies are higher than for pasture. However, most require maintenance and re- leveling. Forestlands are primarily pine and mixed fir and hemlock. Most private lands in the subbasin are forest or rangelands, with approximately 80 percent used for grazing. More than half of the forest stands are significantly overstocked with trees. Wildlife habitat varies in condition. Of 70 total miles, 21 miles of streamside riparian areas are in good condition and another 12 miles are being restored.

The loss of wetland vegetation around the lake has also been linked to lower survival rates for endangered suckers. The lower reaches of the Wood River and Sevenmile Creek provide some rearing habitat for larval and juvenile suckers. The Wood River, Sevenmile Creek and their tributaries support populations of bull and interior redband trout. A highly valued “ catch and release” sport fishery occurs on the Wood River and several of its tributaries. There is significant interest in enhancing riparian habitat along these streams to protect and promote these fisheries. Conservation Accomplishments In the Upper Klamath Lake Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved 12 acres of grazing lands and improved water quality and quantity on 12 acres of irrigated land. Several thousand more acres of wetland restoration are in the process of being planned or implemented around Upper Klamath Lake.

This can be accomplished by either converting pastures to permanent wildlife habitat or by creating riparian pastures. While most pastures are being inefficiently irrigated, conditions do not warrant extensive changes from current flood irrigation systems since water is reused or enters the soil profile Water Storage: In the Upper Klamath Lake Subbasin, the potential for non- traditional water storage presents a unique conservation opportunity. Restoring drained wetlands, still farmed around Upper Klamath Lake, could produce positive benefits for all four resource concerns. By actively managing areas for both seasonal wetlands and farming, water can be both filtered to improve water quality and stored in wetland areas for future use.

The valley once supported a vast network of wet meadows and marshes. This subbasin covers approximately 1.2 million acres and is split from the Middle Lost River Subbasin near Olene. Irrigated agriculture generally occurs in the warmer valleys. Flood is the most common pasture irrigation method, with about 50 percent of the water coming from the USBR project. Pasture condition is fair, and most pastures have not been renovated or re- leveled for some time. Maintenance would increase the efficiencies of 60 to 80 percent of the systems. Alfalfa is customarily sprinkler- irrigated and well- managed. Although irrigation efficiencies are higher than for pasture, many sprinkler systems still need upgrading. Several irrigated crops are grown in the subbasin including cereal grains, potatoes, and strawberry plants. Forestland, range and pasture are grazed by livestock. Rangelands are comprised of juniper and sagebrush steppes. Forestlands are generally mixed conifer. Livestock operations include cow/ calf, stockers and dairies. Confined livestock operations are located throughout the subbasin. The location and duration of confinement may pose a potential risk to water quality. Seven dairies located within the subbasin have existing liquid and dry livestock waste storage facilities.

High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving over the last 10 to 20 years. While agriculture is the dominant land use in this subbasin, other sources of phosphorus and other pollutants exist. Sewage treatment outfalls, on- site sewage disposal systems, wildlife, and natural inputs also contribute nutrients and other pollutants to the system. While historically the river had significant fish runs, it currently supports only a small population of Shortnose and Lost River suckers. Conservation Accomplishments In the Upper Lost River Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved resource conditions on 234 acres of croplands and 5,282 acres of grazing lands, and have improved their management of irrigation water on 5,596 acres of irrigated lands. In addition, 846 acres of riparian and wetland areas have been restored.

On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops. Implementing practices like diverting clean water before it flows through livestock confinement areas near water sources, will reduce the risk of polluted runoff. Water Demand: On both surface-irrigated pastures and cropland areas, there are opportunities for land leveling or smoothing, lining or piping irrigation delivery ditches, upgrading irrigation systems and developing tailwater recovery systems to improve water use efficiency.

Farms near Klamath Falls tend to be smaller, indicating part- time or hobby operations. The area includes 12 irrigation districts and leased lands on the Lower Klamath Wildlife Refuge that receive water supplied by the USBR Klamath Project. Public lands include the refuge, and parts of Modoc and Klamath national forests. Irrigated agriculture includes pasture, alfalfa, cereal grain, potatoes, onions and mint. Roughly 70 percent is irrigated with USBR- supplied water; the rest is obtained from groundwater, individual surface water rights or special USBR contracts. Many fields are either flood or sprinkler irrigated depending on the year and crop. Most farm irrigation diversions lack a means to measure water delivery. Livestock operations include several dairies and cattle feeding operations. Substantial range acreage is used for livestock grazing. Pasture condition is fair and most pastures have not been renovated or re- leveled for some time. Pastures associated with smaller livestock operations in and around Klamath Falls appear to be in the most need of improved pastures and irrigation systems.

Drought conditions and increased competition for available water have increased economic, social, political and environmental concerns and uncertainty over the future. Habitat and water quality are two additional major resource concerns in the subbasin. High water temperatures are usually linked to lack of shade, irrigation return flow or other warm water inputs. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other pollutant sources exist. While the river had significant historic fish runs, it currently supports only a small sucker population. Conservation Accomplishments In the last two years, the Middle Lost River Subbasin has seen significant conservation progress. With assistance from NRCS and local conservation districts, land managers have improved the condition of natural resources on 489 acres of cropland and 3,521 grazing land acres. In addition, 564 acres of riparian and wetland areas have been restored, and water use efficiency has been increased on 3,731 acres of irrigated lands.

Highly effective conservation measures on hay and cropland should focus on updating existing irrigation systems and improving irrigation water management. Water Quality: The use of grazing systems that rotate livestock through smaller pastures will increase forage production, reduce soil compaction and improve water quality. While fishery benefits from restoring riparian areas are minimal, streamside buffers will improve water quality and provide habitat for other wildlife. On cropland, integrated pest management, irrigation scheduling, increasing crop residue or installing filter strips will minimize risks associated with some pesticides used on cereal grains, potatoes, onions and other crops.

The Tulelake Irrigation District and the Tulelake National Wildlife Refuge receive water from the USBR Klamath Project. Tulelake is a remnant of historic Lake Modoc that once connected the subbasin with both Lower and Upper Klamath Lake. The Lost River watershed was once a closed basin. Runoff flowed into Tulelake and evaporated. Pumping plants and drains constructed as a part of the project have provided an outlet from Tulelake, which now functions as an open basin. Irrigated agriculture is generally supplied by the USBR. Alfalfa, grain, potatoes, onions, mint and pasture are the principal crops. Fields are flood or sprinkler irrigated depending on the year and crop. Often diversions lack devices to measure water delivery. Pasture condition is fair, and most have not been renovated for some time. Groundwater provides 40- 50 percent of water for irrigated pastures, and most excess water is reused. Rangeland is the other significant land use. Most ranches are cow/ calf operations that have winter holdings in the subbasin. Rangelands are generally encroached with juniper. Wildlife habitat along the Lost River has reeds and bullrush, providing some habitat for waterfowl and songbirds. Suckers have been located in the river and Tulelake; however, it is not known whether they are successfully reproducing. There are few opportunities to improve habitat along this heavily manipulated reach of the river.

Irrigators depend on water- use decisions made by fellow irrigators and resource managers for their irrigation needs. Drought and increased competition for water leads to the primary resource concern in the basin - a reliable supply of water to meet agriculture, wildlife and other resource needs. Water quality deteriorates as it moves through the USBR project. As measured by total phosphorus, water quality appears to be gradually improving. Agriculture is the dominant land use in this subbasin, but other sources of phosphorus and other pollutants exist. The presence of ESA- listed suckers creates concerns for improving habitat and water quality. The two national wildlife refuges support large waterfowl populations. Farmland on the refuges is leased to farmers to supply grain for waterfowl and shorebirds. These populations depend on refuges, leased lands and adjacent farms during the fall and spring migratory periods. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Tulelake Subbasin during the last two years, significant conservation progress has been made. With assistance from NRCS and local conservation districts, local land managers have improved the condition of natural resources on 72 cropland acres and 1,854 irrigated land acres, and have restored 21 acres of riparian and wetland areas.

Subsurface drainage could be added before re- establishing alfalfa stands, permitting better control of water table and soil moisture levels. During years that alfalfa fields are rotated to grain, winter flooding or pre- season irrigation could be used to reduce water demand. Water Storage/ Yield: Adding subsurface drainage may be the most significant practice to implement on cropland acres. Subsurface drains would allow farmers to winter flood or pre-irrigate fields, thereby reducing their demand for water during the irrigation season. If pre- irrigated, farmers could grow a cereal crop even if water deliveries are cut off during drought years. In addition, juniper control on rangelands will yield additional water to meet downstream needs.

While part of the Upper Klamath Basin, it is an internal drainage basin with only an artificial outlet. Groundwater flows from west to east out of the subbasin under the Mahogany Mountains toward the lake. A channel and pump plant were built to remove floodwaters. This channel is used infrequently and for only short durations. The Klamath National Forest, Butte Valley National Grassland, and the Butte Valley Wildlife Area make up the majority of the public lands. Irrigated agriculture includes alfalfa hay as the predominate crop. Cereal grains, potatoes and strawberry plants are also grown. Crops are usually sprinkler irrigated, and sprinklers are well maintained. Few irrigators measure water applied or schedule irrigation. Cattle operations graze irrigated pastures and meadows scattered throughout the subbasin along with range and forestlands. Pastures are generally flood irrigated and are supplied by streams. Most farm irrigation diversions lack water measuring devices. Mixed conifer forests are found at higher elevations and are generally operated as industrial forests. Range sites are dominated by Western Juniper and are generally in poor condition. Wildlife habitat is generally wetlands in the state wildlife refuge or on national grasslands. Approximately 26 miles of streams on private lands have inadequate riparian vegetation.

Generally, streams in the upper portions of the subbasin support good populations of Brown and Rainbow trout. The Tulelake National Wildlife Refuge and Lower Klamath Lake National Wildlife Refuge support large populations of migratory and permanent waterfowl. Farmland on the refuges is leased to area farmers to supply grain for the waterfowl and shorebirds. The large bird populations depend on the refuges, leased lands and adjacent farms throughout the fall and spring migratory periods for habitat. Both refuges depend upon tailwater from the USBR project to maintain their marshes and ponds. Conservation Accomplishments In the Butte Valley Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, local land managers have restored 27 acres of riparian and wetland areas in the last two years.

Other than limited contributions to groundwater in the Upper Klamath Basin, reductions in water demand only benefit the subbasin. Sprinkler- irrigated hay, cereal crops and row crops dominate land use on the better soils. Highly effective conservation on hay and cropland should focus on improving the overall irrigation efficiency of existing systems. This can be accomplished by upgrading systems and scheduling irrigation. An estimated 40 percent of the existing systems would benefit from maintenance. On controlled flood irrigated pastures, there are opportunities for land leveling or smoothing, lining or piping delivery ditches, and recovering tailwater. Additional water savings and water quality benefits could be gained by converting existing surface irrigation to sprinklers if power is available and affordable. On rangelands, juniper control and improved grazing management are the primary conservation opportunities.

Nearly half of the area is in public ownership. Iron Gate and Copco reservoirs are used extensively for recreational fishing, boating and camping. Whitewater rafting and kayaking are popular below the KC Boyle Dam. The KC Boyle, Copco and Iron Gate dams are used and regulated for power generation. Irrigated agriculture occurs on only 4,000 acres of pasture. Only a few isolated ranches are located in this subbasin. Cattle operations rotate grazing of irrigated pastures with significant acreage of grazed range and forest. Pastures are surface irrigated with a mix of controlled and flood irrigation. All irrigation water is diverted from the river or tributary streams. Most farm irrigation diversions lack devices to measure water. Even though overall irrigation application efficiency is low, the proximity of irrigated pastures to the river allows most excess water diverted to be reused downstream. Private forest and rangelands make up most of the private land, nearly all of which is used for livestock grazing. Much of the rangeland is in poor condition, with heavy juniper encroachment. More than half of the forest stands are overstocked with trees. Wildlife habitat along riparian areas is generally in good condition. Of the 12 miles of riparian areas surveyed, five would benefit from some restoration.

Water withdrawals are insignificant along this stretch of the river. Salmon and steelhead are blocked at Iron Gate Dam from upstream passage. Several resident trout species exist, supporting a recreational fishery. Conservation Accomplishments In the Klamath River East Subbasin during the last two years, some conservation progress has been made. With assistance from NRCS and local conservation districts, land managers have improved the condition of natural resources on 56 acres of cropland, 332 acres of grazing land, and 560 acres of irrigated lands. They have also improved forestland health on 46 acres and have restored 924 acres of riparian and wetland areas.

  	Citation × Citation Citation Abstract Copy Title: Upper Klamath Basin bull trout conservation strategy : part 1, a conceptual framework for recovery, final Author: Light, Jeffrey Year: 1996, 2008, 2005 EXECUTIVE SUMMARY This document presents the framework of a plan to reverse the decline of bull trout (Salvelinus confluentus) populations in the Klamath Basin. If successful, we expect bull trout to recover to a level where they will have a reasonable chance of long-term viability. The work is the collective effort of fish biologists, foresters, other natural resource management professionals, and local landowners representing a diverse array of interests and organizations. Together, these individuals have worked for several years to gather information pertaining to the distribution and status of Klamath bull trout populations and threats to their persistence. The members of the Bull Trout Working Group share the common desire to restore bull trout populations while at the same time sustaining their respective land use interests in the Klamath Basin. This approach provides incentives to all the interested parties to seek agreement on solutions, encouraging cooperative work on an otherwise ambitious and daunting task. The following few pages summarize the plan. Each area is covered again in greater detail in the body of the document. The goals established by the Bull Trout Working Group for this recovery plan are to (1) Secure existing bull trout populations, and (2) Expand the populations to some of their former range and numbers. We pursue these goals with a three step approach of assessment, implementation, and evaluation. We begin with a review of the distribution and status of bull trout generally, then specifically within the Klamath Basin. Next we present available data and interpretations supporting our conclusions regarding the type, magnitude, and extent of physical and biological factors or concerns that may hamper bull trout persistence. Land and fish management activities that contribute to these problem situations are then identified. This is followed by a blueprint for stepwise development and implementation of practical solutions. Finally, a monitoring plan is proposed to measure the success of the recovery efforts. The Klamath Basin Bull trout populations represent a valuable biological resource. These populations exist at the southern edge of the species' distribution, and have distinctive genetic character. In the Upper Klamath River Basin, bull trout are presently found as resident forms in eight isolated headwater streams within six small drainages. (4Headwater streams' in this document refers to very small streams, rather than rivers which are the headwaters for larger rivers). These streams occur in three general locations: they are tributaries of the Sprague River, of the Sycan River and of Upper Klamath Lake. Together, the known populations occupy approximately 23 miles (37 km) of perennial streams. Formerly, bull trout may have occurred in the mainstems of these systems (Gilbert 1897. Dambacher et al. 1992, Roger Smith, ODFW, pers. coram. 1994). In addition to existing populations, other populations are known to have recently occupied nearby streams (Cherry and Coyote creeks, the Upper Sycan River). Estimated current population sizes in each drainage range between 133 and 1,293, indicating that populations are low enough to warrant concern. These population sizes are smaller than the minimum viable population sizes predicted by conservation biology theory. A substantial risk of extirpation via natural disturbance cycles and stochastic events exists for such small populations. Streams that are presently inhabited by bull trout are typically small and spring-fed with steep gradients. They originate in the higher elevations of mountains within the Upper Klamath Basin and flow through forests where land uses range from wilderness and national parkland to commercial forestry and grazing. Eventually, these tributaries or their mainstem receiving waters leave the forest and flow through broad sagebrush-covered valleys or marshes where they widen and flatten. Here livestock grazing and agriculture are the dominant land uses. An assessment of the current situation regarding Klamath Basin bull trout was performed using existing and new information on life history, distribution, habitat requirements by lifestage, environmental requirements, exotic species interactions, angling pressure, land use interactions, habitat fragmentation, population fragmentation and many other factors. Basin-specific information on each of these factors was collected and analyzed, complemented by a thorough review of the literature. Past, present and possible future distributions of bull trout were examined. Particular emphasis was placed on determining the nature and extent of biotic interactions, because this potential agent of bull trout decline has not been thoroughly addressed in other works. Analysis of the assembled information resulted in the identification of several specific natural and anthropogenic factors which are thought to limit the distribution and persistence of bull trout. Habitat quality and quantity are affected by land use to some degree in all currently inhabited bull trout streams except upper Sun Creek. Generally, habitat conditions vary from fair to good in existing bull trout streams. We identified several land uses that have reduced habitat quality. Principal among the abiotic factors of concern is fine sediment loading from (1) road erosion, (2) stream bank and adjacent ground disturbance by livestock, and (3) Bull Trout Document - Final - - 6 - 26-Jan-96 stream-adjacent hillslope erosion from logging. Second among the abiotic factors of concern is elevated temperature. Other concerns include diminished large woody debris (LWD) recruitment, declining bank integrity, low flows, changes in stream morphology, and blocked or hindered fish passage. The relative importance of each of these factors or concerns differs by watershed, or by location within a watershed. In most cases, information on specific issues and their locations is available with sufficient resolution to allow land managers to develop action plans to address them. Possible exceptions may include Deming Creek, where Watershed Analysis has not yet been performed. Based on the assessment results to date, the following strategy was developed to address limiting factors and concerns. Competitive and genetic interactions with non-native brook trout (Salvelinus fontinalis) and brown trout (Salmo trutta) were found to be important biotic factors currently threatening the persistence of bull trout in the Klamath Basin. This conclusion was based on the almost pervasive presence of these exotic competitors and the significance of their negative interactions as determined from the literature and from local observations in headwater streams. Temperature may be a significant issue, especially for juvenile rearing, although the temperature tolerances of bull trout are not well understood. Habitat fragmentation and alteration appear to have been major issues in the past, resulting in population fragmentation, particularly at lower elevations and in larger streams where bull trout may have ranged historically. These final two factors appear less important than exotic competitors or temperature for bull trout in the current limited ranges in headwater streams, though they are important in mainstems and larger tributaries. They will need to be addressed if large scale restoration is undertaken. With the exceptions of temperature and fine sediment, brook trout have habitat requirements and environmental tolerances similar to bull trout, and they thrive in many Klamath Basin headwater streams while bull trout do not. Brown trout pose a competitive threat similar to that posed by brook trout, but the mechanisms of displacement and the areas where they occur differ. Even in environments unaltered by land management, such as Sun Creek within Crater Lake National Park, exotic trout are displacing bull trout. This conclusion is consistent with findings throughout the west, where competition with exotic species has clearly had a major effect on bull trout range, resulting in widespread declines in bull trout distribution. Changes in habitat may have altered competitive interactions between bull trout and other salmonids, both directly and indirectly. Since changes in environmental factors can exacerbate competition issues in sensitive populations, habitat condition remains a concern. Near-term, mid-term, and long-term strategy for Recovery of Bull Trout Populations Our approach to recovery of the Klamath basin's bull trout populations is a two-phase effort corresponding to near- and mid-term objectives, and an examination of possible long-term recovery objectives. It entails securing and maintaining existing populations followed by expansion into former headwater and downstream habitats, and ultimately the possibility of connecting tributaries with mainstem linkages. Assessment, research and monitoring needs associated with each phase were identified (see main body of text). Specific project details such as funding, work schedules, participant responsibilities, specific actions, implementation methods and costs are not presented but are to be developed collectively by the Bull Trout Working Group. Phase 1: Securing existing populations This phase of the recovery plan focuses on the six small drainages where bull trout populations are known to exist today. Here we wish to prevent further decline of individual populations as a step toward securing the viability of the Klamath Basin metapopulation(s).1 This is accomplished by addressing biotic and abiotic factors that threaten the persistence of these populations. The most immediate threat is the continued presence of non-native salmonids. Localized areas of habitat degradation or alteration from sediment inputs and shade removal are an additional serious concern. It may be feasible to isolate bull trout populations above barriers, followed by eradication of brook and brown trout within each isolated stream reach. This approach will be tested early in Phase 7, with particular attention to unforeseen consequences on the ecology of the test streams. Assuming it is viable, this approach will become the focus of Phases 1 & 2, in parallel with habitat enhancement efforts. Habitat enhancement is generally feasible, particularly in areas where roads or livestock are the issues. Where needed, such habitat enhancement efforts are expected to be completed as part of Phases 1&2. It will be necessary to understand the distribution of genetic variation among existing sub-populations of bull trout in order to embark on a well 1 For an understanding of metapopulation considerations, see the body of the text, in particular the section on 'Metapopulations and sub-populations' on page 60. Bull Trout Document - Final - - 7 - 26-Jan-96 directed range expansion program. Baseline data would be essential for genetic monitoring activities and for the development of stocks for establishing new sub-populations in subsequent phases. If successful, the actions taken in Phase 1 are expected to eliminate the direct threats to existing bull trout sub-populations posed by non-native salmonids. Parallel efforts to improve the in-stream physical environment to ensure habitat is suitable for bull trout are expected to eliminate proximate environmental threats to existing bull trout sub-populations. This effort will require that abiotic limiting factors and concerns be addressed via land management activities, most of which fall within the realm of forest land management. Timber harvest and regeneration, roads (construction, use, and maintenance), and livestock grazing programs are considered. Immediate actions may take the form of road erosion abatement, including road abandonment and revegetation. Some of these actions can be accomplished when a particular unit is harvested, while others may be pursued as independent restoration activities (e.g., livestock management plans, culvert replacements). Presently, no in-stream fish habitat improvement projects have been proposed, and none are foreseen for stream reaches affected by this phase of the recovery plan. Most of the concerns related to livestock are focused within the riparian zone. Some riparian locations are much more sensitive than others, for example the large meadow in Long Creek. Actions to address these concerns will vary by landowner and location, and may range from complete riparian exclosure to short-term grazing to continuous but moderate access. The preferred actions will depend on the success of these various strategies in bringing about the desired response of the channel and fish habitat, and can be expected to change as recovery of riparian areas progresses. Effectiveness monitoring will be invaluable for measuring the success of these efforts, and in adapting our management strategy during the implementation. No water diversion concerns have been identified for this phase of the plan, except for Deming Creek, where screening of irrigation ditches may be warranted. Some additional fish management actions may also be applicable in Phase 7, for example to continue to monitor compliance with existing no kill regulations in bull trout streams. Other pertinent fish management issues have been addressed already, for example the cessation of exotic trout stocking (brook, brown or non-native rainbow) in bull trout streams. Phase 2: Expanding the range of bull trout within headwater streams In Phase 2, bull trout populations are refounded in headwater streams which now support brook trout, e.g. Calahan and Cherry creeks, or possibly in creeks without fish, e.g. Sheep Creek on the North Fork Sprague. This serves to expand the number of sub-populations, increases the number of refugia, and increases the overall size of the Klamath metapopulation(s). This is a major step in the establishment of viable metapopulations; by increasing the number of sub-populations, the effect of the loss or decline of any particular sub-population is reduced, making the metapopulation(s) more resilient to natural disturbance, variations in breeding success, disease outbreaks and other stochastic factors. Phase 2 consists of two parts: Phase 2a, in which sub-populations are founded in streams which only recently lost bull trout (e.g. Cherry Creek, Coyote Creek and the upper Sycan River) and Phase 2b, in which sub-populations are founded in other suitable headwater habitat, as indicated by the presence of thriving brook trout sub-populations (e.g. Sevenmile Creek, Calahan Creek, Annie Creek, Camp Creek, Jackson Creek, Deep Creek and Corral Creek). Both parts of Phase 2 are accomplished in much the same way as Phase 7: Barriers are constructed to exclude brook trout and brown trout, then the exotic species are eradicated above the barriers. Bull trout populations are then founded with human-introduced bull trout, whether via transplantation from wild sources or from a hatchery. Care must be exercised to maintain adequate genetic diversity in the founded sub-populations as establishment of genetically healthy populations is a non-trivial task. An inherent risk in newly created sub-populations is the loss of genetic variation (founder effect), which if great enough can reduce the vigor of the population and its long-term viability. As in Phase 7, stresses from abiotic factors, such as excessive delivery of fine sediment, low flows, or warm water temperatures, need to be reduced in parallel with the removal of exotics. Streamside roads, road crossings, low flows in upper reaches, and livestock are situations of concern in many of the streams, and warm temperatures are in some. Also as in phase 7, monitoring for the presence of exotics, bull trout population parameters, and abiotic factors is an important follow-up activity to track and ensure long-term success. In addition, genetic monitoring of newly founded populations is indicated. Bull Trout Document - Final - -8- 26-Jan-96 A possible future direction after Phase 2 Once Phase 2 is complete, the Bull Trout Working Group will pause to assess the efforts completed and plan future efforts. If phases 1 and 2 are successful, there will be significant numbers of bull trout in various tributaries, but possibly little genetic exchange between them. Bull trout range may still be restricted to headwater streams. During the evaluation and reassessment of the recovery effort, the group will re-consider the long-term recovery objectives. Based on what we know now, two possible recovery objectives are likely to be considered. The first such possible objective is the establishment of natural movement corridors between adjacent headwater streams, thereby establishing complete and viable metapopulation(s) of bull trout within the Upper Klamath Basin. Connectivity between headwater streams would allow volitional movement of bull trout. Movement would allow dispersal, founding of new sub-populations, and interbreeding between sub-populations, within the local sub-basin. Establishing natural movement corridors between headwater streams may require that selected reaches of larger tributaries or even portions of mainstem rivers be restored to suitable habitat for bull trout. This would be an ambitious undertaking, which may be infeasible. It might require the elimination or exclusion of exotics, the removal of man-made barriers which prevent movement between streams, or alterations in current land use to reduce anthropogenically induced fine sediment loads, low flows, warm stream temperatures, or changes in channel morphology. The change in focus from headwater streams to larger tributaries represents an escalation in the scale and complexity of the restoration effort. Exclusion of exotics is much more difficult. Land use effects, whether from water diversions or livestock grazing are often more significant. The second possible objective of future efforts after Phase 2 is to attemp to re-establish fluvial populations of bull trout in selected mainstem rivers of the Upper Klamath Basin, in such a way as to connect the sub-populations of each metapopulation. Fluvial bull trout are far larger than stream resident bull trout, and have much higher fecundity as a result. This gives them a tremendous advantage in breeding, whether in founding new sub-populations, or augmenting existing sub-populations. By establishing a fluvial form of bull trout in the Upper Klamath Basin, overall viability of the metapopulation(s) should be greatly increased. Timeline for implementation A prototype Phase 1 implementation is likely to be completed within 2-5 years. Full implementation of Phase 1 may take many years, but the bulk of the work could be completed in 10-20 years. Further assessment work and some aspects of Phase 2 will be accomplished concurrent with Phase 1 efforts over the next several years, but may require 5-10 years before being well underway. Specific timelines for individual projects in phases 1 and 2 and the overall recovery effort will be developed by the Bull Trout Working Group. Summary and prognosis for bull trout populations in the Upper Klamath River Basin If our analysis is accurate, the Klamath Basin's native bull trout populations are imperiled, yet their future need not be bleak. They persist today as a handful of isolated sub-populations in small, headwater streams. If a fluvial life history form existed, as it may have at one time in the Wood River2, no longer occurs or is a very small (i.e., undetectable) component of the current Klamath River Basin population. Gene flow between these sub-populations has apparently ceased. Individual population sizes are small enough to be near or below minimum viable levels as defined by current theorists in conservation biology. Competition from introduced brook and brown trout is widespread, with severe long-term consequences. Habitat conditions vary from stream to stream, depending on the nature and extent of land uses around and downstream of the bull trout tributaries. Fine sediment inputs and elevated stream temperatures are the principal habitat issue. Water withdrawals, altered channels and flood plains, and other anthropogenic influences have contributed to loss of mainstem fluvial habitat, and may have ultimately resulted in habitat fragmentation, followed by isolation of the remaining populations. Together, these conditions do not bode well for the longevity of native bull trout populations. We believe concerted efforts to resolve the identified problems can achieve the goals of maintaining, and possibly restoring, Klamath bull trout populations. Further, we believe that without attention, one or more of the identified limiting factors will almost certainly spell an end to most or all of the sub-populations in the basin. 2 A 330 mm specimen was collected from Fort Creek, a tributary to the Wood River, in 1876.

Bull Trout Document - Final - -9 - 26-Jan-96 Title: Upper Klamath Basin bull trout conservation strategy : part 1, a conceptual framework for recovery, final Author: Light, Jeffrey Year: 1996, 2008, 2005 EXECUTIVE SUMMARY This document presents the framework of a plan to reverse the decline of bull trout (Salvelinus confluentus) populations in the Klamath Basin. If successful, we expect bull trout to recover to a level where they will have a reasonable chance of long-term viability. The work is the collective effort of fish biologists, foresters, other natural resource management professionals, and local landowners representing a diverse array of interests and organizations. Together, these individuals have worked for several years to gather information pertaining to the distribution and status of Klamath bull trout populations and threats to their persistence. The members of the Bull Trout Working Group share the common desire to restore bull trout populations while at the same time sustaining their respective land use interests in the Klamath Basin. This approach provides incentives to all the interested parties to seek agreement on solutions, encouraging cooperative work on an otherwise ambitious and daunting task. The following few pages summarize the plan. Each area is covered again in greater detail in the body of the document. The goals established by the Bull Trout Working Group for this recovery plan are to (1) Secure existing bull trout populations, and (2) Expand the populations to some of their former range and numbers. We pursue these goals with a three step approach of assessment, implementation, and evaluation. We begin with a review of the distribution and status of bull trout generally, then specifically within the Klamath Basin. Next we present available data and interpretations supporting our conclusions regarding the type, magnitude, and extent of physical and biological factors or concerns that may hamper bull trout persistence. Land and fish management activities that contribute to these problem situations are then identified. This is followed by a blueprint for stepwise development and implementation of practical solutions. Finally, a monitoring plan is proposed to measure the success of the recovery efforts. The Klamath Basin Bull trout populations represent a valuable biological resource. These populations exist at the southern edge of the species' distribution, and have distinctive genetic character. In the Upper Klamath River Basin, bull trout are presently found as resident forms in eight isolated headwater streams within six small drainages. (4Headwater streams' in this document refers to very small streams, rather than rivers which are the headwaters for larger rivers). These streams occur in three general locations: they are tributaries of the Sprague River, of the Sycan River and of Upper Klamath Lake. Together, the known populations occupy approximately 23 miles (37 km) of perennial streams. Formerly, bull trout may have occurred in the mainstems of these systems (Gilbert 1897. Dambacher et al. 1992, Roger Smith, ODFW, pers. coram. 1994). In addition to existing populations, other populations are known to have recently occupied nearby streams (Cherry and Coyote creeks, the Upper Sycan River). Estimated current population sizes in each drainage range between 133 and 1,293, indicating that populations are low enough to warrant concern. These population sizes are smaller than the minimum viable population sizes predicted by conservation biology theory. A substantial risk of extirpation via natural disturbance cycles and stochastic events exists for such small populations. Streams that are presently inhabited by bull trout are typically small and spring-fed with steep gradients. They originate in the higher elevations of mountains within the Upper Klamath Basin and flow through forests where land uses range from wilderness and national parkland to commercial forestry and grazing. Eventually, these tributaries or their mainstem receiving waters leave the forest and flow through broad sagebrush-covered valleys or marshes where they widen and flatten.

  Citation × Citation Citation Abstract Copy Title: Cormorant harassment to protect juvenile salmonids in Tillamook County, Oregon Author: Bayer, Range D., 1947- The goal of the Oregon Plan is to restore wild coho and wild steelhead runs. Under the federal Endangered Species Act, wild coho salmon along the Oregon Coast are listed as Threatened and wild Oregon Coast steelhead are a candidate for listing. Although cormorants have been hazed at the Nehalem Estuary for at least 10 years and at the Tillamook and Nestucca Estuaries for at least three years, spawning ground counts of wild coho salmon, winter steelhead, and fall chinook have averaged less since hazing began. Thus, hazing does not appear to be useful in recovering wild salmonids. Hazing is not correlated with consistently improved hatchery returns. The survival of Coded Wire Tag marked coho smolts at the Nehalem was about the same whether hazing occurred or not, the percent return for coho smolts was not significantly greater at the hazed Nehalem than at the nonhazed Salmon River, and the number of returning adult coho salmon was significantly greater with hazing at the Nehalem hatchery but not at the Trask hatchery in the Tillamook Basin. For winter steelhead, the number of returning adults to the Nehalem and jacks to the Cedar Creek hatchery in the Nestucca Basin did not increase significantly with hazing, but the number of jacks returning to the Nehalem did. Changes in fisheries subsequent to hazing are mixed. Coho catches increased with hazing at the Nehalem but not at the Tillamook Basin. Nehalem steelhead catches averaged less with hazing, but chinook fisheries have grown. However, the increase in chinook catches occurred as the number of wild chinook at spawning areas declined, so the larger catch may be a consequence of a greater harvest of wild chinook rather than hazing. Returns may not have increased with hazing because it was ineffective in substantially reducing predation, because smolts saved by hazing died anyway, or because other factors such as unfavorable ocean conditions may have been much more important in affecting smolt survival than hazing. In any case, hazing does not appear to be a panacea for salmonid recovery, and it has costs. During 1996-1999, the Oregon Legislature spent $100,000 for cormorant hazing, and a biological cost of hazing is the disturbance of wildlife other than cormorants.

  Citation × Citation Citation Abstract Copy Title: Aspects of the foraging ecology of humpback whales (Megaptera novaeangliae) in Frederick Sound and Stephens Passage, Southeast Alaska Author: Szabo, Andrew, 1974- The North Pacific humpback whale (Megaptera novaeangliae) population has been increasing at an average annual rate of ~6% since the early 1990s. In northern Southeast Alaska alone, there are now more whales than estimated for the entire North Pacific several decades ago. An understanding of how this growing population is repopulating traditional foraging grounds will benefit from detailed investigations of their prey preferences and trends in whale abundance and distribution relative to those prey. This dissertation examines these issues from late May until early September 2008 in Frederick Sound and Stephens Passage, a Southeast Alaskan feeding area historically used by humpback whales. The foundation for the study is an analysis of the life histories and abundance patterns of euphausiids, the principal prey of humpbacks in the area, during late spring and summer. Four species, Thysanoessa raschii, T. longipes, T. spinifera, and Euphausia pacifica, were identified in plankton net samples collected at random locations throughout the study site (n = 49) and in locations where a strong scattering layer was observed on a 120 kHz echosounder (n = 48). Both sample types varied in euphausiid species composition. Abundance patterns of immature euphausiids coupled with observations of females carrying spermatophores indicated differences between species in spawning schedules. Thysanoessa spp. began spawning in early April with the spring phytoplankton bloom and continued until late June, whereas E. pacifica began spawning in early June and continued until late August. This protracted recruitment of immature euphausiids was geographically widespread throughout the summer in contrast to adults, which, although present all summer, were found primarily in slope and shallow (< 100 m) areas. To determine if humpback whales preferred one euphausiid species or life-stage over another, net sample and hydroacoustic data collected in the vicinity of whales were compared to similar data collected in random locations throughout the study site. This revealed that whales targeted dense aggregations of adult euphausiids, but did not discriminate between the various species, which was surprising because of presumed differences in the energy density linked to their different spawning schedules. Additionally, whales did not spend time in areas with concentrations of immature euphausiids, which were likely not large enough during the study period to be suitable prey. With this preference for adult euphausiids, the abundance and distribution patterns of humpbacks were examined in relation to prey availability. Whale abundance was lowest at the beginning of the study in late May at ca. 68 whales and peaked in late July at ca. 228 animals – approximately 12% of the region’s estimated abundance for the study year. This study did not detect a concomitant increase in the availability of adult euphausiids, which is unsurprising since immature euphausiids would not recruit into the adult population until after the end of the study, and post-spawning mortality and predation pressure is presumably high during this time. Instead, whales clustered increasingly around comparatively fewer prey as the summer progressed. These observations, combined with a plateau in whale abundance after July, suggest that their abundance in the area was limited by euphausiid availability. Estimates of whales using the study site during the summer have remained similar over several decades despite a dramatic increase in humpback numbers in Southeast Alaska and elsewhere in the North Pacific. The results from this study suggest that, although the study site remains important seasonally to some whales, it is not a significant source of prey responsible for regional population growth in general. More likely, it is part of a network of feeding areas that has influenced the population trend. Further insight into these and the other issues raised in this dissertation could come from several additional analyses. An extended sampling season that captures the recruitment of immature euphausiids into the adult population would reveal whether a given year's prey cohort represents an important resource to whales in that same year, which has potential implications for interpreting mid-late season whale abundance patterns. As well, a photo-identification study would be useful in characterizing whale residency patterns and determining whether the abundance trends reflect a relatively small subset of the regional population using the area for most of the season or a continuous flow of a larger portion of the population. Finally, similar analyses as those outlined here but conducted in other areas within the region would provide additional insight into the network’s capacity to support the recovering whale population.

  Citation × Citation Citation Abstract Copy Title: Natural history and ecology of larval Lost River suckers and larval shortnose suckers in the Williamson River-Upper Klamath Lake System Author: Cooperman, Michael S. We monitored larval Lost River and shortnose suckers from natal beds in the Williamson and Sprague rivers to nursery grounds in Upper Klamath Lake. Downstream movements occurred at night, in the middle of the channel, and on the falling limb of the hydrograph. Ages, sizes, and developmental stages of larvae from spawning beds and the river mouth were similar, while larvae collected contemporaneously from the lake tended to be larger and better fed. Our results indicate in-river rearing was rare, that a rapid outmigration to the lake was favorable for larval survival, and that modification of the lower Williamson River does not appear to have prohibited rapid entry or preclude access to Upper Klamath Lake. Within the Williamson River and Upper Klamath Lake, emergent macrophytes supported significantly higher abundance, larger mean sizes, and better fed larvae than submerged macrophytes, woody vegetation, or open water areas. Analysis of seven years of larval sucker production and survival corroborated the habitat analysis by identifying a positive relationship with emergent macrophyte availability as well as a positive relationship with air temperature and a negative relationship with high wind. These findings illustrate the importance of fast growth, appropriate habitat and calm hydrological conditions for larvae, and are highly consistent with other larval fish studies.

  Citation × Citation Citation Abstract Copy Title: Systematics, variation, distribution, and biology of lampreys of the genus Lampetra in Oregon Author: Kan, Ting Tien Based on the number of velar tentacles and the form of longitudinal lingual laminae found in Lampetra (Entosphenus) t. tridentata and its closely related forms, the taxon Entosphenus should not be considered as a genus as commonly adopted, but, along with the taxa Lethenteron and Lampetra, should be regarded as a subgenus of the genus Lampetra. The genus Lampetra is distinct for various reasons, including particularly the character that no cusps are present in the area distal to the lateral circumorals. Six nominal species, belonging to the subgenera Entosphenus and Lampetra, have been known to occur in four of the seven major drainage systems of Oregon. The anadromous L. (E.) t.tridentata, is widespread in the Columbia River and Coastal drainage systems, occurring in most streams with access to the ocean regardless of distance to the ocean, as long as suitable spawning grounds and ammocoete habitats are present. Morphometrics and dentitional features vary little over its geographical range. The number of trunk myomeres and the adult body size vary appreciably so that two categories of regional forms, coastal and inland, may be recognized. The coastal forms are generally smaller and have fewer trunk myomeres compared to those of the larger inland forms. The spawning migration begins from the late spring to late summer for the coastal forms but may occur much earlier for the inland forms. The adult body size appears to be positively correlated with absolute fecundity, but is negatively correlated with relative fecundity. Duration of the larval period is from four to six years. Metamorphosis usually takes place in the fall. Macrophthalmia are known to enter the ocean over a long period, those descending coastal streams enter salt water in the late fall and early winter, whereas the peak of emigration from inland streams is in the early spring. Duration of its marine parasitic phase appears to be from 20 to 40 months. The small landlocked L. (E.) t. kawiaga n. subsp., found only in the Klamath and Goose Lake drainage systems in southern Oregon and northern California, differs from t. tridentata in body size and various meristic and morphometric characters. Its lacustrine parasitic phase is about 12 months long. L. (E.) lethophaga, the nonparasitic derivative of tridentata, occurs in the Klamath and probably also the Goose Lake drainage system. It is characterized by an extension of the larval phase and by a greatly reduced post-larval period. The presumably extinct L. (E. ) minima, a parasitic derivative of tridentata, found formerly only in Miller Lake, Oregon, possessed a number of characters that were concomitants of dwarfism, the distinctive feature of the species. Relationships and evolution among the subgenus Entosphenus were discussed. Distributional records of L. ayresii and L. richardsoni of the subgenus Lampetra in Oregon were given. Evidence indicates that a complex of clinal races, including L. pacifica Vladykov, 1973, may exist in the latter species.

  Citation × Citation Citation Abstract Copy Title: The physiology ecology and run diversity of adult Pacific lamprey, Entosphenus tridentatus, during the freshwater spawning migration Author: Clemens, Benjamin Jacob, 1976- Pacific lamprey, Entosphenus tridentatus, have shown recent and rapid declines in abundance. These anadromous fish return to streams where they mature, spawn and die. It has been inferred that Pacific lamprey enter freshwater and reside for ~ 1 year before spawning. This long exposure to the freshwater environment may affect the plasticity of the maturation process and the migration timing of Pacific lamprey. Diversity in run times and body size has been observed for Pacific lamprey, yet it is unknown if this diversity is induced by the freshwater environment or if it is genetic. My first goal was to describe the maturation and migration characteristics of adult Pacific lamprey during their freshwater migration. My second goal was to use these data to make an estimation of the run diversity in Pacific lamprey. I conducted three complementary studies, in the laboratory and the field, to achieve these goals. I held immature adult lamprey (non-ripe fish that had ceased parasitic feeding in the ocean and had returned to freshwater) in the laboratory at temperatures that mimicked what these fish would experience in the wild, during the summer (mean: 21.8 °C), and another group of lamprey at cooler temperature (mean: 13.6 °C) to compare maturation timing and characteristics. The warm water group of lamprey showed significantly greater proportional decreases in body mass following temperature exposure than fish in the cooler water. All fish exposed to the warm water matured the following spring (8-10 months later) whereas only about half of the fish from the cool water exposure matured. To understand the migration distances and timing of adult Pacific lamprey, I tracked radio-tagged fish throughout the Willamette Basin above Willamette Falls, Oregon, by airplane and recorded their location. Fish migrated primarily during the spring to early summer period before stopping during the remainder of summer, when peak river temperatures (≥ 20°C) occurred. These fish tended to remain stationary through the fall and winter. However, at least a few fish continued to migrate upstream after September. I monitored maturation characteristics of adult Pacific lamprey, over time at Willamette Falls, Oregon and compared these fish with recent migrants collected from the Pacific Ocean as they entered freshwater. The results suggest a unimodal spawn timing between April and June, at water temperatures < 20 °C. Between July and mid-September, as water temperatures peaked at ~ 25 °C, relatively immature fish for both sexes prevailed. Warm summer temperatures coincided with an increase and prevalence of testicular atrophy in males, and I also observed a large die-off of lamprey during this time. The immature fish had maturation stages and phenotypic characteristics similar to recent migrants collected at the mouth of the Klamath River, suggesting that the immature fish at Willamette Falls would spawn the following year, and spawners in any given year may have been recent migrants during the previous year. However there is a temporal overlap in the spring of immature and mature fish, and I found evidence from gonad histology of maturing fish as they entered the river from the ocean, suggesting that a cohort is comprised of recent migrants that spawn within several weeks of entering freshwater, and another cohort is comprised of recent migrants that mature and spawn at least 1 year later. I hypothesize that the recent migrants that would likely spawn shortly after entering freshwater are akin to a winter or "ocean maturing" steelhead, Oncorhynchus mykiss, that optimizes feeding and growth in the open ocean for a few years before entering freshwater to spawn low in the river system shortly afterwards. Alternatively, these lamprey may be similar to coastal cutthroat trout, O. clarki clarki, that feed and grow in the coastal areas of the ocean for a few months before entering freshwater to spawn. There could be other less apparent explanations as well. I also hypothesize that the lamprey that would likely spawn within ~ 1 year of entering freshwater are akin to a "stream maturing" steelhead that foregoes feeding and growth opportunities, enters freshwater during the summer – fall, and accesses spawning grounds to spawn at temperatures that promote evolutionary fitness via successful spawning the following spring. Based on the results of my research, I hypothesize that warm summer temperatures (> 20 °C) can act as a strong selection factor against stream maturing Pacific lamprey in two ways. First, these temperatures may expedite their maturation, while at the same time slowing their migration. If these hypotheses are true, then I predict an uncoupling of spawn timing with optimal habitat characteristics, that would promote fitness, in the upper watershed. Second, summer temperatures may cause gonad atrophy and death prior to spawning. This scenario may select for ocean maturing Pacific lamprey. Title: The physiology ecology and run diversity of adult Pacific lamprey, Entosphenus tridentatus, during the freshwater spawning migration Author: Clemens, Benjamin Jacob, 1976- Pacific lamprey, Entosphenus tridentatus, have shown recent and rapid declines in abundance. These anadromous fish return to streams where they mature, spawn and die. It has been inferred that Pacific lamprey enter freshwater and reside for ~ 1 year before spawning. This long exposure to the freshwater environment may affect the plasticity of the maturation process and the migration timing of Pacific lamprey. Diversity in run times and body size has been observed for Pacific lamprey, yet it is unknown if this diversity is induced by the freshwater environment or if it is genetic. My first goal was to describe the maturation and migration characteristics of adult Pacific lamprey during their freshwater migration. My second goal was to use these data to make an estimation of the run diversity in Pacific lamprey. I conducted three complementary studies, in the laboratory and the field, to achieve these goals. I held immature adult lamprey (non-ripe fish that had ceased parasitic feeding in the ocean and had returned to freshwater) in the laboratory at temperatures that mimicked what these fish would experience in the wild, during the summer (mean: 21.8 °C), and another group of lamprey at cooler temperature (mean: 13.6 °C) to compare maturation timing and characteristics. The warm water group of lamprey showed significantly greater proportional decreases in body mass following temperature exposure than fish in the cooler water. All fish exposed to the warm water matured the following spring (8-10 months later) whereas only about half of the fish from the cool water exposure matured. To understand the migration distances and timing of adult Pacific lamprey, I tracked radio-tagged fish throughout the Willamette Basin above Willamette Falls, Oregon, by airplane and recorded their location. Fish migrated primarily during the spring to early summer period before stopping during the remainder of summer, when peak river temperatures (≥ 20°C) occurred. These fish tended to remain stationary through the fall and winter. However, at least a few fish continued to migrate upstream after September. I monitored maturation characteristics of adult Pacific lamprey, over time at Willamette Falls, Oregon and compared these fish with recent migrants collected from the Pacific Ocean as they entered freshwater.

  Citation × Citation Citation Abstract Copy Title: GIS modeling of potential marine protected areas in the Northwest Atlantic via biological and socioeconomic parameters Author: Keith, Charles M. Overfishing of our national marine resources has degraded some of the most productive fishing regions in the Northwest Atlantic Ocean, most notably the Gulf of Maine and Georges Bank. These regions may have shifted from productive trophic regimes to a less than optimal state therefore reducing fishers’ catches and associated revenue from commercially targeted species (Sinclair and Murawski, 1997, Jennings et al, 2001). Marine protected areas (MPAs) have been offered as an effective management tool to preserve biodiversity, enhance commercial fisheries, and protect against poor decisions in fisheries management (Bohnsack, 1999). Geographic information systems (GIS) bring together the fields of geography and fisheries management to help build a better understanding of the spatial interactions of complex marine environments (e.g., Kracker, 1999). Using GIS and spatial management such as MPAs can help fishery managers conserve and improve the population status of important biological resources while helping to preserve commercial fishing, an important social and political industry in New England. Incorporating the needs of stakeholders in management decisions is necessary in order to implement an effective fisheries management strategy (e.g., Malakoff, 2002). This study used a weighted optimization raster model in a GIS to compare biological significant regions, which were composed of biodiversity estimates and spawning and juvenile habitats, to important commercial fishing grounds in the Gulf of Maine and Georges Bank. Biodiversity, spawning and juvenile data values were derived from fishery independent data collected by 2 the National Marine Fisheries Service in Woods Hole, MA. The essential commercial fishing zones were created from Vessel Trip Reports, which are derived directly from reports sent in by federally permitted fishers. The weighted model compares the biologically important resources from an area, or cell, to the level of commercial fishing occurring in the same cell using simple mathematically algorithms in map algebra. The model output shows where placement of MPAs might be most beneficial in order to conserve marine resources and enhance fisheries, as well as areas where fishing is more suitable. Output can be viewed in multiple ways, a spectrum of values ranging from negative numbers to positive ones or simply as areas important for the fishing community or potential MPA. The more negative the value in the spectrum output then the more important the area would be for fishers and conversely the more positive the output then the more suitable the area would be for possible MPA designation. The optimization model can be tuned to meet management goals and objectives by adjusting the weighting scenarios for the input variables. The model design can be used for multiple species and ecosystem management or to protect specifically targeted species of particular concern. Managers may use the output to delineate MPAs in a variety of ways depending on the conditions of the resources and the prospects of the fishing community. Managers will enjoy greater success as the needs of both fishers and biological resources are met.

  Citation × Citation Citation Abstract Copy Title: Migration, movement, and habitat use of humpback whitefish (Coregonus pidschian) in the Copper River Delta, Alaska Author: Neilson, Brian J. Research conducted on humpback whitefish Coregonus pidschian in the Copper River Delta, Alaska has revealed a complex life history involving seasonal migrations and the occupation of a variety of freshwater and marine habitats including lacustrine, riverine, estuarine, and marine. Forty-five whitefish were tagged with radio transmitters in 2006 and 2007, and another 29 whitefish were tagged with acoustic tags in 2008. In addition, otolith chemistry was used to evaluate marine habitat use of humpback whitefish sampled from McKinley Lake in the Copper River Delta, Alaska. Movements and migration of tagged fish were tracked using biotelemetry techniques from boats, airplanes, and fixed receiver stations throughout the spring, summer, and fall. Sagittal otoliths were extracted from 20 humpback whitefish and a chemical analysis was performed to evaluate levels of Sr:Ca. Biotelemetry and sampling results revealed seasonal migrations where humpback whitefish migrated into McKinley Lake in mid to late spring and left the lake by late summer and early fall. Fish migrated to the Copper River in the fall by traveling down Alaganik Slough and then to the Copper River by traveling through Pete Dahl Cutoff Slough or the Gulf of Alaska. Fish travel up the Copper River presumably to their spawning grounds. Nine tagged fish returned to McKinley Lake in 2007 and four tagged fish in 2008, indicating some fidelity to the summer feeding site. Otolith chemistry detected marine migrations in 45% of the samples. Three migratory behaviors were observed, while some individuals inhabited only freshwater environments, some individuals made single migrations to marine habitats, and other individuals made multiple migrations to marine habitats. Age of whitefish ranged from 2 to 9 years. Analysis of small-scale movement of humpback whitefish in McKinley Lake found movement rates to be significantly higher at dusk compared to night in one sampling period. However, diel movement activity in all other diel periods did not significantly differ, suggesting arrhythmic diel movement. A large portion of the lake was occupied at any given time, but not all areas were used equally. Activity levels, measured by change in zones, were variable between dates and indicated that fish often moved between detection zones. An increase in activity was observed in individuals 48 h prior to migration from the lake. This study provides the first documentation of migration, movement, and habitat use of humpback whitefish in the Copper River Delta, Alaska. Results of this study will help inform management of humpback whitefish in order to sustain populations into the future. This information should be considered in land use and species management planning in the Copper River basin including fish passage and harvest regulations.

  Citation × Citation Citation Abstract Copy Title: Distribution, habitat use, and growth of juvenile Chinook salmon in the Metolius River Basin, Oregon Author: Lovtang, Jens C. Chinook salmon (Oncorhynchus tshawytscha) have been absent from their historic spawning and rearing grounds in the Metolius River Basin in central Oregon since 1968, when fish passage was terminated at the Pelton Round Butte Hydroelectric Project on the Deschutes River. Plans have been developed to reestablish passage of anadromous fish through the Project. However, only anecdotal evidence exists on the historic distribution of spring Chinook juveniles in the Basin. A recent approach to characterizing habitat quality for anadromous fishes in the Basin was the development of HabRate (Burke et al. In Press), which presented a relative quality rating of habitat based upon published fish-habitat relationships at the stream reach spatial scale. The present study was initiated to test the predictions of HabRate for summer rearing juvenile Chinook salmon in the Metolius Basin. Chinook salmon fry were released in the winters of 2002 and 2003, and their densities and sizes were quantified via snorkeling and fish collection in six unique study reaches in the upper Metolius River Basin. Each of these stream reaches varied in terms of temperature, habitat availability, invertebrate drift availability, and fish community composition. My observations were not consistent with the qualitative predictions of HabRate. Moreover, habitat utilization was not consistent among study reaches. Similar to other qualitative habitat rating models (e.g. Habitat Suitability Indices (Raleigh et al. 1986) and Instream Flow Incremental Methodology (Bovee 1982)), HabRate's predictions rely solely on physical habitat characteristics, with the assumption that habitat will be used consistently among stream reaches (i.e. a pool in one reach is of equal importance as a pool in another reach). My results suggest that the unique ecological setting of each study reach provides the context for understanding the patterns of growth, habitat use, and diurnal activity of juvenile Chinook salmon. The inclusion of ecological components, such as food availability, the bioenergetic constraints of temperature, and the risk of predation can make these models more biologically realistic. Growth of juvenile Chinook salmon among study reaches had a curvilinear relationship to water temperature, and was also positively related to the drift density of invertebrate biomass. In three collection seasons (fall 2002, spring 2003 and fall 2003) 41 to 69% of the variations in fork lengths were explained by a multiple regression model including temperature and invertebrate drift. Based on these findings, I present a conceptual growth capacity model based on the tenets of bioenergetics as a basis for understanding the relative quality of the habitat among stream reaches for juvenile Chinook salmon. Fish community composition can help to explain observed patterns in habitat utilization and diel activity patterns. In the study reaches that had a greater presence of adult trout (potential predators), observations of juvenile Chinook salmon in mid-channel habitat were infrequent to non-existent during the day and abundances were higher in all habitat types at night. In the study reaches with colder water temperatures, observed juvenile Chinook salmon densities were higher at night. I suggest that habitat selection and diurnal activity patterns in some study reaches are reflective of strategies taken by the fish to minimize risks of predation.

These wetlands provided important feeding and nesting grounds for resident and migratory birds as well as spawning and protection habitat for many fish and other invertebrate species. However, the Delta's wetlands started to disappear as water was used for agricultural and urban uses in the United States and Mexico. The 1944 United States-Mexico water treaty, which allocates 1.8 million m³/year to Mexico, did not define a minimum flow to maintain the Delta's ecosystems. The resulting degraded Delta lead to the perception in the 1980s that the Delta was a dead ecosystem. This study investigates whether this "dead Delta" perception is valid. Its central hypothesis is that regenerated vegetation in riparian and flood plain zones is associated with surplus river flows during the 1990s. A vegetation analysis, using satellite imagery and field methods, shows that native trees have regenerated during the last 20 years, and now account for 23% of vegetation in a 100 km, non-perennial, stretch of river below the United States-Mexico border. A spatial trend analysis using multi-temporal data on percent vegetation cover indicates that there are 6,320 hectares that show a significant increasing trend (p-value<0.05) in vegetation cover, with the Delta's riparian zone having at least 18% of its area showing this trend. The study estimates that once in four years February to April flow of 300 million m³ (at 80-120 m³/s) is sufficient to germinate and establish new cohorts of native trees, and highlights the need for smaller but more periodic flows in order to maintain wetland areas. It is concluded that there is clear evidence of the resilience of the Delta's ecosystems and that the "dead Delta" perception is no longer valid. There exist critical habitat in the Delta that needs to be protected, while there also exist short and long term opportunities to ecologically enhance and expand current habitat. Hydrological and ecological studies are needed to estimate specific water requirements for these areas in order to efficiently target them for immediate and long term conservation actions.

  Citation × Citation Citation Abstract Copy Title: Using parasite community data and population genetics for assessing Pacific sardine (Sardinops sagax) population structure along the west coast of North America Author: Baldwin, Rebecca E. B. Pacific sardines (Sardinops sagax) are an economically and ecologically important forage fish which transfer energy from planktonic primary producers and secondary consumers to upper trophic predators. Previous genetics studies of Pacific sardine suggested a panmictic population with a shallow genetic structure. However, more than one subpopulation within the Central California Offshore management unit may exist based on recovering larger individuals at higher latitudes and a temporal difference in sardine spawning off Southern California and the Pacific Northwest. Potential for separate sardine subpopulations questions the long-standing paradigm of an annual migration of individuals to feeding grounds off the Pacific Northwest in the summer with migrants returning to Southern California in the fall to spawn the following spring. This study applied parasite community analyses and population genetics techniques to assess migration patterns and stock structure of Pacific sardine in the California Current from Vancouver Island, British Columbia, Canada to San Diego, California, USA. A coastwide sardine migration is supported by the geographical distribution of Myosaccium ecaude (Trematoda), but a second migration pattern was identified within the Pacific Northwest from the geographic distribution of Lecithaster gibbosus (Trematoda). Population genetics studies identified a panmictic distribution for: 1) the trematode M. ecaude using a 283bp portion of the NADH-dehydrogenase subunit 1 (ND1) mitochondrial DNA (mtDNA) gene; and 2) three species of Anisakis nematodes (A. simplex s.s., A. pegreffii, and A. simplex 'C') using a 524bp portion of the cytochrome c oxidase 2 (cox2) mtDNA gene. These results suggest that the extensive movement of all of the potential hosts utilized by these parasites, the limited oceanographic barriers, and complexity in the California Current are not preventing the mixing of M. ecaude or Anisakis species populations. The diversity and availability of fish and cetacean species that undergo extensive migrations along the full length of the California Current system may enable large geographically distributed population sizes of these parasite species. We thus cannot confirm the existence of separate Pacific sardine subpopulations within the California Current by the occurrence of parasite communities or the population genetics analyses of M. ecaude or the three Anisakis species.
