The TRD began operations in 1963, diverting up to 90 percent of the Trinity River's average annual yield at Lewiston, California. Access to 109 river miles of fish habitat and replenishment of coarse sediment from upstream river segments were permanently eliminated by Lewiston and Trinity Dams. Within a decade of completing the TRD, the adverse biological and geomorphic responses to TRD operations were obvious. Riverine habitats below Lewiston Dam degraded and salmon and steelhead populations noticeably declined.

Year: 2001, 2004 Abstract Implementation of the Federal Clean Water Act and Oregon Senate Bill 1010 is proceeding under two simultaneous processes in Oregon. The Oregon Department of Environmental Quality is responsible for developing Total Maximum Daily Load (TMDL) allocations for water-quality limited water bodies. The Oregon Department of Agriculture is striving to develop Management Area Plans to provide guidance for management of private agricultural lands to meet Clean Water Act objectives. Both processes seek input from local advisory committees comprised of landowners and other stakeholders, and technical review committees. Klamath Lake and Klamath River have been designated water quality impaired for several parameters including nutrients. Researchers have attempted to determine the extent of agriculture's contributions to nutrient enrichment of surface waters in the Upper Klamath Basin. Two United States Geological Survey (USGS) studies focused attention on drainage of agricultural lands adjacent to Klamath Lake as a significant source of nutrient loading in the lake. A preliminary draft report by the Klamath River TMDL committee identified the outlet for drainage waters from the Klamath Irrigation Project to the Klamath River at the Straits Drain as a point source for nutrient loading. Preparation of a final TMDL for this sub-watershed was tabled pending development of a TMDL for Klamath Lake and its tributaries. Insufficient data are available to determine the relative contributions of agricultural activities, natural background sources, and other potential sources of nutrient enrichment to establish numerical limits for nutrient loading from agricultural lands. From 1998 through 2000, the Klamath Experiment Station has investigated nutrient loading from drainage of agricultural lands adjacent to Klamath Lake, natural background sources including major springs and several artesian wells, and loading to the Klamath Irrigation Project from diversions out of Klamath Lake and Klamath River. Findings indicate contributions from agricultural lands adjacent to Klamath Lake have been overestimated, and the Klamath Irrigation Project is probably a net sink for nutrients diverted out of Klamath Lake and Klamath River. Data to support these assertions are presented. Introduction Most of the surface waters in the Klamath Basin are included in the Oregon department of Environmental Quality (DEQ) 303D list as water-quality limited. While the only criterion for listing of many streams is temperature, based on a preliminary standard of 64°F, Klamath Lake and Klamath River are listed for chlorophyll a, dissolved oxygen, un-ionized ammonia, and pH.

Year: 1994, 2005 PROGRESS REPORT FOR INVESTIGATIONS ON BLUE CREEK FT 1992 ABSTRACT The U.S. Fish and Wildlife Service, Coastal California Fishery Resource Office in Arcata, California, was funded to investigate chinook salmon roncorhvnchus tshawvtschav spavming use, juvenile salmonid emigration, and characterize stream habitats in Blue Creek, a tributary to' the Klamath River; California. 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.

Year: 1977 A basic modular exploration sequence which includes a carefully balanced selection of geological, geochemical, and geophysical modules is developed for geothermal prospecting in the eastern Basin and Range. The cost per square mile for application of this exploration architecture is $461.00. If one were to expand this basic system to include virtually all techniques being routinely employed in geothermal prospecting today, then the cost per square mile would increase to $790.00. This latter expenditure rate is difficult to justify, but some increase above the $461.00 basic cost appears to be warranted to make exploration costs about equal to land acquisition costs and model-test drilling costs. Total costs per discovery appear to range from $6M to $27M depending upon assumptions, when the costs of exploring for ''dry'' prospects are included in the costs of the discoveries. Development and operating costs are not included in the analysis. The basic exploration architecture described here is compared with others previously advanced in the literature. If a common basic is used for computing costs of individual exploration modules, then there is no great cost disparity between any of the architectures reviewed Title: Geothermal Exploration Architecture.

Development and operating costs are not included in the analysis. The basic exploration architecture described here is compared with others previously advanced in the literature. If a common basic is used for computing costs of individual exploration modules, then there is no great cost disparity between any of the architectures reviewed Close

Major issues in recent years have included changing the role of science in decision-making, modifying critical habitat procedures, reducing conflicts with Department of Defense activities, incorporating further protection and incentives for property owners, and increasing protection of listed species, among others. In addition, many have advocated enacting as law some ESA regulations promulgated during the Clinton Administration. 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, species of plants and animals (both vertebrate and invertebrate) can be 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 broader ecosystem decline: the most common cause of listing species is habitat loss. 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 implement the administrative provisions of the ESA in each subsequent fiscal year. In the 108th Congress, two bills were reported by the House Committee on Resources, but not enacted, that would have amended the ESA to modify scientific peer review and critical habitat procedures. Interior appropriations measures funded Fish and Wildlife Service programs related to endangered species (P.L. 108-108 provided $265 million for FY2004; P.L. 108-447 provided $262 million for FY2005). 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; this prohibition appears to have been made permanent by ?205 of Div. C of P.L. 108-447. P.L. 108-148 (Healthy Forests Act) authorized hazardous fuels reduction projects on BLM and national forest lands, including those containing habitat for listed species; directed establishment of a healthy forests reserve program to promote recovery of listed species; and directed the Secretary of the Interior to provide property rights assurances to landowners enrolled in the healthy forests reserve program.

Investigations that began in October, 1988, have continued to date, with this reporting period covering Fiscal Year 1993 (FY 1993, October, 1992, through September, 1993). In addition, some information already presented in previous progress reports, FY 1989 - FY 1992, is summarized. In 1993, adult chinook spawner escapements were addressed by snorkel surveys of redds and carcasses. Spawner numbers were very low, with only 17 redds observed in fall/winter 1992-93. The peak count of adult chinook was 136 fish in early November. Emigrating juvenile s&lmonids were trapped at river kilometer (rkm) 3.35 with a screw trap and panel weir. The screw trapping period extended from April through July for a total of 91 trapping nights. Screw trap catches totaled 14,526 chinook, 912 steelhead and 69 coho. Chinook emigration was spread over the entire trapping period, with increases during mid-May, and from mid-June throughout July. A juvenile weir was operated 60 nights, and caught a total of 6,334 chinook, 992 steelhead, 49 coho salmon, and 0 juvenile cutthroat. The total index of production for emigrating chinook during the 1993 juvenile trapping period was 101,819. Chinook that were marked with coded-wire tags (n-12,299) were released, with other juvenile fish, into Blue Creek at rkm 3.3. Mean temperatures varied from 6.3 to 18.6 ?C and flows ranged from 0.91 cubic m/s (32 cubic feet/s) to 202.6 cubic m/s (7,160 cubic feet/s) during FY 1993. Extreme flows for FY 1993 were the lowest and highest observed by CCFRO since the project began in 1989, and lower than the previous low of the 13 years of record.

  	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.

  	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.

  	Citation × Citation Citation Abstract Copy Title: Power produced from hot dry rock geothermal resources: a case study for the Imperial Valley, California Author: Cummings, R.G. Year: 1979 The case study described here concerns an HDR system which provides geothermal fluids for a hypothetical electric plant located in California's Imperial Valley. Primary concern is focused on the implications of differing drilling conditions, as reflected by costs, and differing risk environments for the potential commercialization of an HDR system. Drilling costs for best, medium and worst drilling conditions are taken from a recent study of drilling costs for HDR systems. Differing risk environments are presented by differing rate of return requirements on stocks and interest on bonds which the HDR system is assumed to pay; rate of return/interest combinations considered are 6%/3%, 9%/6%, 12%/9% and 15%/12%. The method used for analyzing the HDR system involves a two-stage process. In stage 1, the maximum amount that the electric plant can pay to an HDR system for geothermal fluids is calculated for alternative busbar prices of electricity received by the electric plant. In stage 2, costs for the HDR system are calculated under differing assumed risk environments and drilling conditions. These two sets of data may then be used to analyze the minimum busbar price of electricity - which defines a maximum fuel bill that could be paid to the HDR system by the electric plant - which could result in the HDR system's full recouperation of all production and drilling costs.

  	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.

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. Close

The Lost River sucker {Deltistes luxatus) is a federally listed, endangered fish species endemic to Upper Klamath Lake?a large, shallow hypereutrophic lake in southern Oregon. Sucker population declines in the lake over the past few decades are thought to be partly attributable to extreme water quality conditions, including elevated ammonia concentrations and elevated pH, that occur during summer cyanobacterial blooms. I analyzed structural changes in gills of larval Lost River suckers after they were exposed to elevated pH and elevated ammonia concentrations in chronic toxicity tests conducted in the laboratory. Histopathological changes in sucker lamellae were observed at ammonia concentrations that did not significantly decrease survival, growth, whole-body ion content, or swimming performance. Structural changes that I evaluated included O2 diffusion distance, lamellar thickness, hyperplasic and hypertrophic mucous cells, and infiltration of white blood cells into the lymphatic space. The increases in diffusion distance and lamellar thickness were statistically significant (P < 0.05). These gill changes are indicative of potentially compromised respiratory and ionoregulatory capacity. Because in this species gill structural changes appear to be a more sensitive indicator of stress in eutrophic water quality conditions than are the more traditional sublethal indices, gill histopathology might be useful for monitoring the health of Lost River suckers in Upper Klamath Lake.

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.

  	Citation × Citation Citation Abstract Copy Title: Raising Upper Klamath Lake, appraisal study : draft. Author: U.S. Dept. of the Interior, Bureau of Reclamation Year: 2000, 2008, 2005 Executive Summary This report documents an appraisal-level evaluation of raising Upper Klamath Lake in south-central Oregon. The lake is the State's largest freshwater lake and is a principal storage feature of the Klamath Project. The Klamath Project provides water for irrigating approximately 240,000 acres in the Klamath Basin in south-central Oregon and northern California. The Klamath Project was authorized for construction in 1905, and work began shortly thereafter. In 1921, Link River Dam was constructed at the south end of the lake, near the city of Klamath Falls, to provide regulation of the lake. Background The listing of fish species as threatened or endangered, and the Federal responsibility to protect Tribal trust assets, have placed increasing demands on the limited water supply of the Klamath Project and reduced its flexibility to meet demands. There is an immediate need to increase water supplies and improve the timing of their availability to improve fish and wildlife habitat and water quality. The Bureau of Reclamation (Reclamation) began the Klamath Basin Water Supply Initiative (Initiative) in 1996 to identify options for increasing water supplies in the Klamath River Basin. The Initiative is a joint effort partnership of Reclamation, the Klamath River Compact Commission, the California Department of Water Resources, and the Oregon Water Resources Department. The Initiative identified 96 options for increasing water supplies and recommended 44 for further study, including raising Upper Klamath Lake. Options Evaluated The evaluation documented in this report considers increasing the maximum operating level of Upper Klamath Lake by 2 feet by raising Link River Dam. Two options are described: (1) raising existing levees around the lake to contain the lake within its current surface area and (2) allowing the lake to spread and flood adjacent lands. Option 1 constrains the higher water surface elevation to the current shoreline. Modifications would be provided to protect all existing land, roads, and structures surrounding the lake. A 2-foot-high parapet will be constructed on top of the dam to accommodate the higher water level. Major construction activities include: Raising Upper Klamath Lake ? Eight sections of new seawall, totaling 6.6 linear miles ? Modifying 14 sections of existing dikes with roads, totaling 44.3 linear miles ? Modifying 10 sections of existing dikes without roads, totaling 25.2 linear miles ? Two sections of new dikes with roads, totaling 1.9 linear miles ? Three sections of new dikes without roads, totaling 2.7 linear miles ? Armoring two sections of existing dikes, totaling 3.5 linear miles ? Raising one bridge and county and local roads at seven locations, totaling 1.3 miles of roads ? Raising 2.5 miles of a State highway ? Rehabilitating 126 private residences (relocating septic tanks, providing foundation drainage, and landscaping) ? Rehabilitating headworks and intake structures at 10 locations ? Relocating an existing boat dock The estimated cost of Option 1 is $125 million. Option 2 does not protect structures and property, but, instead, allows the lake to spread beyond the current shoreline and flood adjacent lands. Existing dikes will be breached, and existing roads that would otherwise be inundated will be raised. Either existing headworks and water intakes at various locations will be retrofitted for the higher water surface elevation, or the associated facility will be purchased. Link River Dam will be modified as in Option 1. Major construction activities include: ? Breaching (every % mile) 14 sections of existing dikes with roads, totaling 44.3 linear miles of dikes ? Breaching 10 sections of existing dikes without roads, totaling 25.3 linear miles of dikes ? Armoring 3.0 linear miles of an existing dike ? Raising one bridge and county and local roads at three locations, totaling 0.6 mile of roads Executive Summary ? Raising 2.5 miles of an existing State highway ? Rehabilitating headworks and intake structures at nine locations ? Relocating an existing boat dock The estimated cost of Option 2 is $129 million, including $113 million for the acquisition of private land and structures. Raising Upper Klamath Lake 2 feet will increase storage by approximately 170,000 acre-feet, or about 25 percent. Winter floodflows, which are presently spilled to the Klamath River and not available for project use, will be stored and made available to help meet water needs for endangered species, Tribal trust resources, agricultural contractors, and national wildlife refuges. Future operation of the enlarged lake will be contingent upon acquisition of appropriate rights to divert and store additional water in the lake and may require filing an application for the appropriation of additional water with the Oregon Water Resource Department. Costs associated with implementing either Option 1 or Option 2 are significant. In addition, implementing either option will have both positive and negative impacts on the natural and human environment. Recommendations Several engineering studies are recommended. These include: ? Estimating quantities, properties, and availability of embankment and riprap materials, and identifying their locations (quaries) ? Constructing a modified dike test section to assess construction methodology and performance of rockfill protection ? Using detailed aerial topography (maximum 1-foot contours) of the Upper Klamath Lake shoreline to better define existing features and required improvements ? Conducting a comprehensive survey of all shoreline structures to provide a better estimate of the work required and associated costs ? Inspecting existing dam gates and concrete bulk heads to determine if additional modifications are required for the higher reservoir water surface ? S-3 Raising Upper Klamath Lake ? Developing site-specific, cost-effective alternatives to the proposed shore protection features ? Identifying and securing suitable rights-of-way Recreation facilities need to be analyzed in more detail to determine impacts and associated protection, relocation, and modification costs. A user survey and appropriate mapping of all recreational facilities has been initiated to determine existing recreation use levels and assist in the analysis of potential impacts. A detailed hydrology study demonstrating that unappropriated water is available to fill the additional storage in Upper Klamath Lake is recommended. Better descriptions of area-elevation-capacity relationships and evaporation and transpiration losses will also be needed. The following environmental studies are recommended: ? Develop detailed topographic information for the entire lake and surrounding area to predict the extent of flooding and potential vegetation changes ? Develop topographic mapping in 1-foot increments to predict effects on wetland vegetation ? Determine potential streamflow changes below Link River Dam and potential benefits to threatened and endangered fishes ? Determine impacts to upland areas that would be inundated by the higher reservoir water surface elevations. The following economic studies are recommended: ? Determine all costs (e.g., planning, design, construction, mitigation, and operation, maintenance, and replacement) ? Determine benefit/cost Early development and implementation of a public involvement plan will be essential to a feasibility study. Various studies to identify and analyze social impacts and impacts to environmental justice, Tribal trust, and cultural resources are recommended. Opportunities to avoid or lessen adverse impacts will also need to be identified. S-4 Title: Raising Upper Klamath Lake, appraisal study : draft.

NERC Operation Post Office Box 270308 Fort Collins, CO 80527 Executive Summary In 1999, we sampled Lost River { Deltistes luxatus) and shortnose ( Chasmistes brevirostris) suckers from 5 April to 17 June at five shoreline spawning locations in Upper Klamath Lake ( UKL). Trammel nets were set to encompass identified spawning areas and were fished approximately 1- 1.5 hours before sunset until 3 hours after sunset or until 20 or more fish were captured. A total of 808 Lost River and 19 shortnose suckers were captured from Sucker, Silver Building, Ouxy, and Boulder springs, and Cinder Flats. The majority of Lost River suckers were captured at Cinder Flats ( 35%) and Sucker Springs ( 34%), followed by Ouxy Springs ( 16%), Silver Building Springs ( 12%), and Boulder Springs ( 3%). Males dominated the catch at all sites, but the sex ratios at Cinder Flats and Silver Building Springs were particularly skewed towards males. We recaptured 32 Lost River suckers that had been tagged during previous years sampling efforts. All of these fish, with the exception of two fish tagged at Ball Point in July, were originally tagged during the spawning season at shoreline spawning areas in UKL. This information provides further evidence that distinct stocks of Lost River suckers exist based on spawning location ( i. e., UKL and Williamson River). We also recaptured 23 Lost River suckers that were tagged in 1999 at shoreline spawning areas. Approximately half of these fish were recaptured at different locations than tagged indicating these fish were moving between spawning areas. The size offish captured at shoreline spawning areas decreased as the spawning season progressed, although the decrease in size was not as dramatic as reported in previous years. A limited number of shortnose suckers were captured at shoreline spawning areas in 1999, with a majority sampled after 1 May. Previous data for shortnose suckers at these sites is limited with respect to size, timing of spawning, sex composition, and relative numbers. Continuation of systematic sampling efforts at shoreline spawning areas will provide valuable information on the demographics and life history of Lost River and shortnose suckers utilizing these areas.

Introduction Severe water quality problems in Upper Klamath Lake ( UKL) have led to critical fisheries concerns for the region. Historically, UKL was eutrophic but has become hypereutrophic ( Goldman and Home 1983) presumably due to land- use practices within the basin ( USFWS 1993). As a result, the algal community has shifted to a monoculture of the blue- green algae Aphanizomemon flos- aquae and massive blooms of this species have been directly related to poor water quality episodes in UKL. The growth and decomposition of dense algal blooms in the lake frequently cause extreme water quality conditions characterized by high pH ( 9- 10.5), widely variable dissolved oxygen ( anoxic to supersaturated), and high ammonia concentrations (> 0.5 mg/ 1 unionized). In addition to water quality problems associated with A. flos- aquae, it is believed the loss of marsh habitat near the lake, timber harvest, removal of riparian vegetation, livestock grazing, and agricultural practices within the basin has contributed to hypereutrophic conditions. It is likely that these disturbances have altered the UKL ecosystem substantially enough to contribute to the near monoculture of A. flos- aquae. Investigations in 1913 documented the algal community as a diverse mix of blue- green and diatom communities, however, by the 1950' s A. flos- aquae was dominant ( USFWS 1993). The Lost River sucker ( Deltistes luxatus) and shortnose sucker ( Chasmistes brevirostris) are endemic to the Upper Klamath Basin of California and Oregon ( Moyle 1976). Declining population trends for both species were noted as early as the mid- 1960' s, however, the severities of the population declines were not evident until the mid- 1980' s. In 1988 the U. S. Fish and Wildlife Service listed both Lost River and shortnose suckers as endangered. Suspected reasons for their decline included damming of rivers, dredging and draining of marshes, water diversions, hybridization, competition and predation by exotic species, insularization of habitat, and water quality problems associated with timber harvest, removal of riparian vegetation, livestock grazing, and agricultural practices ( USFWS 1993). The U. S. Geological Survey, Biological Resources Division ( BRD) has been conducting field investigations on Lost River and shortnose suckers in UKL since 1994. The majority of these sampling efforts have focused on catching fish in UKL and the Lower Williamson River. Sampling in the Lower Williamson River focused on developing indices of relative abundance of Lost River and shortnose suckers. In 1999, Oregon State University continued sampling in the Lower Williamson River fishing trammel nets from April to August at four standardized locations. In addition to sampling efforts in the Lower Williamson River, BRD crews conducted periodic sampling at several shoreline spawning areas on the east side of UKL. This sampling was beneficial because it provided information on species composition, size, and sex ratios of suckers utilizing these areas. However, temporal changes in abundance may have been missed because consistent sampling never occurred throughout the entire spawning season ( Perkins et al, In preparation). Recently, there has been increased concern on the effects of water level management in UKL on spawning suckers. Information is needed on the timing, relative abundance, and distribution of sucker spawning in UKL to make informed decisions with respect to management of lake elevation. In 1999, we conducted systematic trammel netting surveys at Sucker, Silver Building, Ouxy, and Boulder springs and Cinder Flats along the east shore of UKL. In addition, we sampled periodically at Barkley Springs and Modoc Point to determine if suckers were utilizing these areas for spawning. This report summarizes data collected in 1999 on shoreline spawning populations of Lost River and shortnose suckers with emphasis on timing, species composition, sex ratios, and relative abundance. Methods We conducted systematic trammel netting surveys at five locations along the east shore of UKL ( Figure 1). We began sampling at Cinder Flats, Sucker, Silver Building, and Ouxy springs in early April with Boulder Springs added to the list of sampling sites on 27 April. In addition to these sites, we periodically sampled at Barkley Springs and Modoc Point ( Table 1). We attempted to sample each site twice per week although certain sites were only sampled once per week when catch rates of suckers were low ( i. e., less than 5 fish per evening). Trammel nets were fished for about 4 hours ( approximately 1- 1.5 hours before sunset until 3 hours after dark) or until we captured 20 or more fish. Nets used at individual sites varied in length from 15- 30 m, were 1.8 m tall with two outer panels ( 30cm bar mesh), an inner panel ( 3.8 cm bar mesh), a foam core float line, and a lead core bottom line. Generally, we set 1- 2 nets starting at the shoreline and extending out to encompass the perimeter of the identified spawning area. Nets were checked at approximately 1 hour intervals and captured fish were cut from the inner mesh panel and placed in a mesh cage and processed within 2 hours. Suckers were identified by species and sex, measured to the nearest mm ( fork length), inspected for tags ( both PIT and Floy tags), and examined for physical afflictions ( e. g., presence oiLernaea spp. and lamprey scars). If a sucker did not have a PIT tag, one was inserted with a hypodermic needle along the ventral surface 1- 2 cm anterior of the pelvic girdle. The catch per unit effort ( CPUE) of adult Lost River suckers was calculated for individual sampling locations for each evening sampled. Because identified spawning areas varied in size we used different length trammel nets to encompass the spawning areas. We did not attempt to standardize CPUE based on length of trammel nets used at each location. Results We sampled shoreline spawning areas from 5 April - 17 June capturing a total of 808 Lost River suckers and 19 shortnose suckers from 5 sites ( Table 1). Lost River and shortnose suckers were captured at Sucker Springs, Silver Building Springs, Ouxy Springs, and Cinder Flats, while only Lost River suckers were captured at Boulder Springs. No suckers were captured at Barkley Springs and Modoc Point ( Table 1). The majority of Lost River suckers were captured at Cinder Flats ( 35%) and Sucker Springs ( 34%; Figure 2). Males dominated the catch at all sites and were generally smaller ( mean length = 538 mm) than females captured ( mean length = 596 mm). In particular, sex ratios ( males to females) were most skewed at Cinder Flats and Silver Building Springs ( Figure 3). Large females (> 650 mm) were captured at most sites, except Boulder Springs, and the size range offish captured over time remained similar with the exception that a fewer large individuals (> 600 mm) were captured in the late sampling period ( 1 May - 17 June) as compared to the early sampling period ( 6- 30 April; Figure 4; Appendix Figure A). The catch of shortnose suckers was limited at all sites sampled. Most ( 12 of 19) of the shortnose suckers were collected at Sucker Springs, with 1- 3 fish captured at Cinder Flats, Ouxy Springs, and Silver Building Springs ( Table 1). We identified 8 males and 8 females during the sampling period and were unable to determine sex for three individuals. The mean size of shortnose suckers was 360 mm ( range 289- 528 mm) similar to data reported by Perkins et al. ( In preparation) from Sucker, Silver Building, and Ouxy springs. We observed the highest CPUE of Lost River suckers at Cinder Flats ( mean CPUE= 12.7/ h) followed by Sucker Springs ( mean CPUE= 6.0/ h), Silver Building Springs ( mean CPUE = 2.8/ h), and Ouxy Springs ( mean CPUE= 2.4/ h) ( Figure 5). On three occasions at Cinder Flats, 20 or more suckers were captured within an hour or less resulting in the termination of sampling for the evening. CPUE was calculated for sampling dates at Boulder Springs ( mean CPUE= 1.4/ h), although comparisons with other sites is not applicable because this site was not initially included in systematic sampling efforts. We did not calculate CPUE for shortnose suckers. We captured a total of 32 Lost River and 2 shortnose suckers that were tagged during previous years sampling efforts. The majority ( 96%) of these fish was originally tagged at shoreline locations ( Table 2), which is consistent with historical recapture data ( Appendix Table A). Two Lost River suckers were originally tagged at Ball Point in UKL in July, after the spawning season. In addition, most Lost River suckers were recaptured before 1 May, including 15 fish that were collected at Sucker Springs during two sampling occasions in March ( Figure 6). We also recaptured a total of 21 Lost River suckers that were tagged in 1999 at shoreline spawning areas. Approximately half of these fish were recaptured at different areas than where they were tagged, indicating that some suckers are moving between spawning areas within the season ( Table 3). Discussion Our sampling indicated the spawning period for Lost River suckers lasted from mid- March through the beginning of June at shoreline spawning areas in 1999. The catch of Lost River suckers was dominated by males at all sites sampled, particularly at Cinder Flats and Silver Building Springs. Perkins et al., ( In preparation) reported skewed sex ratios at shoreline spawning locations following the fish kills that occurred in UKL from 1995- 1997. However, the ratios we observed were considerably higher than those reported by Perkins et al., ( In preparation). At this time we are unable to determine the reason for the sex ratios observed. It is possible that males remain longer at the spawning areas than females making them more vulnerable to capture. Perkins et al., ( In preparation) observed spawning acts and reported that males remained near the actual site where spawning occurs while females move onto the spawning site only when ready to spawn. We captured 23 Lost River suckers twice in 1999 and all but one of these fish were males. However, it is difficult to determine if this percentage is due to males remaining at these sites longer than females or a reflection of the existing sex ratios. Another possible explanation could be the large numbers of males in the catch are from the 1991- 1993 year classes and females from these year classes have yet to be recruited into the adult population. The majority of males captured ( 81%) were between 475 - 574 mm. Age and growth information from Lost River suckers collected during the 1996- 1997 fish kills indicate these fish would be between 5- 9 years old ( USGS, BRD, 10 unpublished data). Perkins et al., ( In preparation) reported that male Lost River suckers migrating up the Williamson River begin to be recruited into the adult population starting at age 4+, while females did not begin to mature until age 7+ . These data were based on examining length frequency distributions and noting when fish from the 1991 year class, which is presumed to be a strong year class, began showing up in trammel net catches. Fish from the 1991 year class would have been age 8+ in 1999. Buettner and Scoppetone ( 1990) examined opercles from Lost River suckers collected during the 1986 fish kill in UKL and reported that individuals matured between 6- 14 years of age with the peak being 9 years. It is possible that in the next few years more females from the 1991- 93 year classes will be recruited into the adult population spawning at shoreline areas. Our data provides additional evidence that distinct stocks of Lost River suckers may exist based on fidelity to spawning area. Of the 32 suckers we recaptured from previous years sampling efforts, all but two were originally tagged at shoreline spawning locations. The two fish that were not originally tagged at shoreline spawning locations were captured at Ball Point in July and were not presumed to be spawning in this location. Perkins et al. ( In preparation) reported that of 316 Lost River and 11 shortnose suckers recaptured at shoreline spawning areas all were originally tagged at shoreline spawning locations. Continuation of systematic sampling at both shoreline spawning areas and the Williamson and Sprague rivers will continue to provide information on potential separation of spawning populations. The majority of recaptured fish were tagged during the first half of our sampling efforts including 13 fish that were recaptured on 25 March while sampling with Larry Dunsmoor of the Klamath Tribes. Historically, the majority of sampling effort at 11 shoreline spawning locations occurred prior to 1 May, which may explain why most recaptures were collected during the early part of our sampling period. In fiiture years, we plan to continue systematic sampling through June to determine if temporal aspects of spawning remain consistent between years. The size offish captured at shoreline spawning areas decreased as the spawning season progressed, particularly near the end of our sampling period, although the decrease was not as dramatic as reported by Perkins et al., ( In preparation). It is possible that individual timing of Lost River sucker spawning is affected by size. Scoppettone et al., ( 1986) observed that smaller, younger cui- ui ( Chasmistes cujus) at Pyramid Lake spawned at the end of the spawning season. We believe further investigation is needed to determine if differences in spawning timing among individuals is due to size or related to stock differences. A limited number of shortnose suckers were captured in 1999. Sampling continued well into June and was sufficient to detect spawning concentrations of shortnose suckers at these sites. Based on previous sampling conducted at shoreline spawning areas, there appears to be a decreasing trend in the number of shortnose suckers captured at these sites ( Perkins, et al., In preparation). Our sampling efforts at shoreline spawning areas on the east side of UKL represents the first time these areas have been systematically sampled during the spawning season. Continuation of systematic sampling at these areas is important to provide information on species composition, timing and duration of spawning, fidelity to spawning areas, sex ratios, size distribution, and relative abundance. How these 12 population characteristics change over time will also provide important insights into the population stability of Lost River and shortnose suckers in UKL. 13 Literature Cited Buettner, M.

NERC Operation Post Office Box 270308 Fort Collins, CO 80527 Executive Summary In 1999, we sampled Lost River { Deltistes luxatus) and shortnose ( Chasmistes brevirostris) suckers from 5 April to 17 June at five shoreline spawning locations in Upper Klamath Lake ( UKL). Trammel nets were set to encompass identified spawning areas and were fished approximately 1- 1.5 hours before sunset until 3 hours after sunset or until 20 or more fish were captured. A total of 808 Lost River and 19 shortnose suckers were captured from Sucker, Silver Building, Ouxy, and Boulder springs, and Cinder Flats. The majority of Lost River suckers were captured at Cinder Flats ( 35%) and Sucker Springs ( 34%), followed by Ouxy Springs ( 16%), Silver Building Springs ( 12%), and Boulder Springs ( 3%). Males dominated the catch at all sites, but the sex ratios at Cinder Flats and Silver Building Springs were particularly skewed towards males. We recaptured 32 Lost River suckers that had been tagged during previous years sampling efforts. All of these fish, with the exception of two fish tagged at Ball Point in July, were originally tagged during the spawning season at shoreline spawning areas in UKL. This information provides further evidence that distinct stocks of Lost River suckers exist based on spawning location ( i. e., UKL and Williamson River). We also recaptured 23 Lost River suckers that were tagged in 1999 at shoreline spawning areas. Approximately half of these fish were recaptured at different locations than tagged indicating these fish were moving between spawning areas. The size offish captured at shoreline spawning areas decreased as the spawning season progressed, although the decrease in size was not as dramatic as reported in previous years. A limited number of shortnose suckers were captured at shoreline spawning areas in 1999, with a majority sampled after 1 May. Previous data for shortnose suckers at these sites is limited with respect to size, timing of spawning, sex composition, and relative numbers. Continuation of systematic sampling efforts at shoreline spawning areas will provide valuable information on the demographics and life history of Lost River and shortnose suckers utilizing these areas.

Introduction Severe water quality problems in Upper Klamath Lake ( UKL) have led to critical fisheries concerns for the region. Historically, UKL was eutrophic but has become hypereutrophic ( Goldman and Home 1983) presumably due to land- use practices within the basin ( USFWS 1993). As a result, the algal community has shifted to a monoculture of the blue- green algae Aphanizomemon flos- aquae and massive blooms of this species have been directly related to poor water quality episodes in UKL. The growth and decomposition of dense algal blooms in the lake frequently cause extreme water quality conditions characterized by high pH ( 9- 10.5), widely variable dissolved oxygen ( anoxic to supersaturated), and high ammonia concentrations (> 0.5 mg/ 1 unionized). In addition to water quality problems associated with A. flos- aquae, it is believed the loss of marsh habitat near the lake, timber harvest, removal of riparian vegetation, livestock grazing, and agricultural practices within the basin has contributed to hypereutrophic conditions. It is likely that these disturbances have altered the UKL ecosystem substantially enough to contribute to the near monoculture of A. flos- aquae. Investigations in 1913 documented the algal community as a diverse mix of blue- green and diatom communities, however, by the 1950' s A. flos- aquae was dominant ( USFWS 1993). The Lost River sucker ( Deltistes luxatus) and shortnose sucker ( Chasmistes brevirostris) are endemic to the Upper Klamath Basin of California and Oregon ( Moyle 1976). Declining population trends for both species were noted as early as the mid- 1960' s, however, the severities of the population declines were not evident until the mid- 1980' s. In 1988 the U. S. Fish and Wildlife Service listed both Lost River and shortnose suckers as endangered. Suspected reasons for their decline included damming of rivers, dredging and draining of marshes, water diversions, hybridization, competition and predation by exotic species, insularization of habitat, and water quality problems associated with timber harvest, removal of riparian vegetation, livestock grazing, and agricultural practices ( USFWS 1993). The U. S. Geological Survey, Biological Resources Division ( BRD) has been conducting field investigations on Lost River and shortnose suckers in UKL since 1994. The majority of these sampling efforts have focused on catching fish in UKL and the Lower Williamson River. Sampling in the Lower Williamson River focused on developing indices of relative abundance of Lost River and shortnose suckers. In 1999, Oregon State University continued sampling in the Lower Williamson River fishing trammel nets from April to August at four standardized locations. In addition to sampling efforts in the Lower Williamson River, BRD crews conducted periodic sampling at several shoreline spawning areas on the east side of UKL. This sampling was beneficial because it provided information on species composition, size, and sex ratios of suckers utilizing these areas. However, temporal changes in abundance may have been missed because consistent sampling never occurred throughout the entire spawning season ( Perkins et al, In preparation). Recently, there has been increased concern on the effects of water level management in UKL on spawning suckers. Information is needed on the timing, relative abundance, and distribution of sucker spawning in UKL to make informed decisions with respect to management of lake elevation. In 1999, we conducted systematic trammel netting surveys at Sucker, Silver Building, Ouxy, and Boulder springs and Cinder Flats along the east shore of UKL. In addition, we sampled periodically at Barkley Springs and Modoc Point to determine if suckers were utilizing these areas for spawning. This report summarizes data collected in 1999 on shoreline spawning populations of Lost River and shortnose suckers with emphasis on timing, species composition, sex ratios, and relative abundance. Methods We conducted systematic trammel netting surveys at five locations along the east shore of UKL ( Figure 1). We began sampling at Cinder Flats, Sucker, Silver Building, and Ouxy springs in early April with Boulder Springs added to the list of sampling sites on 27 April. In addition to these sites, we periodically sampled at Barkley Springs and Modoc Point ( Table 1). We attempted to sample each site twice per week although certain sites were only sampled once per week when catch rates of suckers were low ( i. e., less than 5 fish per evening). Trammel nets were fished for about 4 hours ( approximately 1- 1.5 hours before sunset until 3 hours after dark) or until we captured 20 or more fish. Nets used at individual sites varied in length from 15- 30 m, were 1.8 m tall with two outer panels ( 30cm bar mesh), an inner panel ( 3.8 cm bar mesh), a foam core float line, and a lead core bottom line. Generally, we set 1- 2 nets starting at the shoreline and extending out to encompass the perimeter of the identified spawning area. Nets were checked at approximately 1 hour intervals and captured fish were cut from the inner mesh panel and placed in a mesh cage and processed within 2 hours. Suckers were identified by species and sex, measured to the nearest mm ( fork length), inspected for tags ( both PIT and Floy tags), and examined for physical afflictions ( e. g., presence oiLernaea spp. and lamprey scars). If a sucker did not have a PIT tag, one was inserted with a hypodermic needle along the ventral surface 1- 2 cm anterior of the pelvic girdle. The catch per unit effort ( CPUE) of adult Lost River suckers was calculated for individual sampling locations for each evening sampled. Because identified spawning areas varied in size we used different length trammel nets to encompass the spawning areas. We did not attempt to standardize CPUE based on length of trammel nets used at each location. Results We sampled shoreline spawning areas from 5 April - 17 June capturing a total of 808 Lost River suckers and 19 shortnose suckers from 5 sites ( Table 1). Lost River and shortnose suckers were captured at Sucker Springs, Silver Building Springs, Ouxy Springs, and Cinder Flats, while only Lost River suckers were captured at Boulder Springs. No suckers were captured at Barkley Springs and Modoc Point ( Table 1). The majority of Lost River suckers were captured at Cinder Flats ( 35%) and Sucker Springs ( 34%; Figure 2). Males dominated the catch at all sites and were generally smaller ( mean length = 538 mm) than females captured ( mean length = 596 mm). In particular, sex ratios ( males to females) were most skewed at Cinder Flats and Silver Building Springs ( Figure 3). Large females (> 650 mm) were captured at most sites, except Boulder Springs, and the size range offish captured over time remained similar with the exception that a fewer large individuals (> 600 mm) were captured in the late sampling period ( 1 May - 17 June) as compared to the early sampling period ( 6- 30 April; Figure 4; Appendix Figure A). The catch of shortnose suckers was limited at all sites sampled. Most ( 12 of 19) of the shortnose suckers were collected at Sucker Springs, with 1- 3 fish captured at Cinder Flats, Ouxy Springs, and Silver Building Springs ( Table 1). We identified 8 males and 8 females during the sampling period and were unable to determine sex for three individuals. The mean size of shortnose suckers was 360 mm ( range 289- 528 mm) similar to data reported by Perkins et al. ( In preparation) from Sucker, Silver Building, and Ouxy springs. We observed the highest CPUE of Lost River suckers at Cinder Flats ( mean CPUE= 12.7/ h) followed by Sucker Springs ( mean CPUE= 6.0/ h), Silver Building Springs ( mean CPUE = 2.8/ h), and Ouxy Springs ( mean CPUE= 2.4/ h) ( Figure 5). On three occasions at Cinder Flats, 20 or more suckers were captured within an hour or less resulting in the termination of sampling for the evening. CPUE was calculated for sampling dates at Boulder Springs ( mean CPUE= 1.4/ h), although comparisons with other sites is not applicable because this site was not initially included in systematic sampling efforts. We did not calculate CPUE for shortnose suckers. We captured a total of 32 Lost River and 2 shortnose suckers that were tagged during previous years sampling efforts. The majority ( 96%) of these fish was originally tagged at shoreline locations ( Table 2), which is consistent with historical recapture data ( Appendix Table A). Two Lost River suckers were originally tagged at Ball Point in UKL in July, after the spawning season. In addition, most Lost River suckers were recaptured before 1 May, including 15 fish that were collected at Sucker Springs during two sampling occasions in March ( Figure 6). We also recaptured a total of 21 Lost River suckers that were tagged in 1999 at shoreline spawning areas. Approximately half of these fish were recaptured at different areas than where they were tagged, indicating that some suckers are moving between spawning areas within the season ( Table 3). Discussion Our sampling indicated the spawning period for Lost River suckers lasted from mid- March through the beginning of June at shoreline spawning areas in 1999. The catch of Lost River suckers was dominated by males at all sites sampled, particularly at Cinder Flats and Silver Building Springs. Perkins et al., ( In preparation) reported skewed sex ratios at shoreline spawning locations following the fish kills that occurred in UKL from 1995- 1997. However, the ratios we observed were considerably higher than those reported by Perkins et al., ( In preparation). At this time we are unable to determine the reason for the sex ratios observed. It is possible that males remain longer at the spawning areas than females making them more vulnerable to capture. Perkins et al., ( In preparation) observed spawning acts and reported that males remained near the actual site where spawning occurs while females move onto the spawning site only when ready to spawn. We captured 23 Lost River suckers twice in 1999 and all but one of these fish were males. However, it is difficult to determine if this percentage is due to males remaining at these sites longer than females or a reflection of the existing sex ratios. Another possible explanation could be the large numbers of males in the catch are from the 1991- 1993 year classes and females from these year classes have yet to be recruited into the adult population. The majority of males captured ( 81%) were between 475 - 574 mm. Age and growth information from Lost River suckers collected during the 1996- 1997 fish kills indicate these fish would be between 5- 9 years old ( USGS, BRD, 10 unpublished data). Perkins et al., ( In preparation) reported that male Lost River suckers migrating up the Williamson River begin to be recruited into the adult population starting at age 4+, while females did not begin to mature until age 7+ . These data were based on examining length frequency distributions and noting when fish from the 1991 year class, which is presumed to be a strong year class, began showing up in trammel net catches. Fish from the 1991 year class would have been age 8+ in 1999. Buettner and Scoppetone ( 1990) examined opercles from Lost River suckers collected during the 1986 fish kill in UKL and reported that individuals matured between 6- 14 years of age with the peak being 9 years. It is possible that in the next few years more females from the 1991- 93 year classes will be recruited into the adult population spawning at shoreline areas. Our data provides additional evidence that distinct stocks of Lost River suckers may exist based on fidelity to spawning area. Of the 32 suckers we recaptured from previous years sampling efforts, all but two were originally tagged at shoreline spawning locations. The two fish that were not originally tagged at shoreline spawning locations were captured at Ball Point in July and were not presumed to be spawning in this location. Perkins et al. ( In preparation) reported that of 316 Lost River and 11 shortnose suckers recaptured at shoreline spawning areas all were originally tagged at shoreline spawning locations. Continuation of systematic sampling at both shoreline spawning areas and the Williamson and Sprague rivers will continue to provide information on potential separation of spawning populations. The majority of recaptured fish were tagged during the first half of our sampling efforts including 13 fish that were recaptured on 25 March while sampling with Larry Dunsmoor of the Klamath Tribes. Historically, the majority of sampling effort at 11 shoreline spawning locations occurred prior to 1 May, which may explain why most recaptures were collected during the early part of our sampling period. In fiiture years, we plan to continue systematic sampling through June to determine if temporal aspects of spawning remain consistent between years. The size offish captured at shoreline spawning areas decreased as the spawning season progressed, particularly near the end of our sampling period, although the decrease was not as dramatic as reported by Perkins et al., ( In preparation). It is possible that individual timing of Lost River sucker spawning is affected by size. Scoppettone et al., ( 1986) observed that smaller, younger cui- ui ( Chasmistes cujus) at Pyramid Lake spawned at the end of the spawning season. We believe further investigation is needed to determine if differences in spawning timing among individuals is due to size or related to stock differences. A limited number of shortnose suckers were captured in 1999. Sampling continued well into June and was sufficient to detect spawning concentrations of shortnose suckers at these sites. Based on previous sampling conducted at shoreline spawning areas, there appears to be a decreasing trend in the number of shortnose suckers captured at these sites ( Perkins, et al., In preparation). Our sampling efforts at shoreline spawning areas on the east side of UKL represents the first time these areas have been systematically sampled during the spawning season. Continuation of systematic sampling at these areas is important to provide information on species composition, timing and duration of spawning, fidelity to spawning areas, sex ratios, size distribution, and relative abundance. How these 12 population characteristics change over time will also provide important insights into the population stability of Lost River and shortnose suckers in UKL. 13 Literature Cited Buettner, M.

  	Citation × Citation Citation Abstract Copy Title: The Oregon plan for salmon and watersheds Author: Oregon. 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.

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.

Year: 2002, 2005 Determining Surface Water Availability in Oregon By Richard M. Cooper, PE Abstract The Oregon Water Resources Department (Department or OWRD) limits appropriation from Oregon streams to assure new applicants use of surface water a reasonable amount of time and to minimize regulatory conflict. The standards for new appropriation of water are: (1) consumptive use from allocations for out-of-stream uses can total no more than the 80-percent ex-ceedance natural stream flow, and (2) allocations for in-stream flows can be no more than the 50-percent exceedance natural stream flow. OWRD has created and maintains a database of the amount of surface water available for appropriation for most waters in the state. This database is used to evaluate applications for new uses of water. Water availability (WA) is obtained from natural stream flow (QNSF) by subtracting existing storage (ST), out-of-stream consumptive uses (CU) and in-stream demands (IS). WA = QN -ST-CU-IS Ideally, water availability would be calculated for every watershed above a point of diversion or in-stream demand. Practically, the number of watersheds must be limited. The watersheds selected for analysis are called Water Availability Basins (WABs). Stream flow can be highly variable, and it is useful to characterize it in some way, usually by a statistic, e.g., a monthly or annual mean. For water availability, it is important to know how often water is available. The appropriate statistic in this case is exceedance stream flow. This statistic tells us how often to expect a given rate of stream flow to occur. Exceedance stream flows are determined directly from gage records, or for ungaged streams, by estimation through modeling. When determined from gage records, the exceedance flows must be corrected to a common base period, and then, to natural stream flow. When determined through modeling, the exceedance flows are estimated from statistical models that relate watershed characteristics to natural stream flow. The models are derived by multiple linear regression. Storage is water retained in a reservoir. It is debited from water availability when the water is stored. It diminishes availability both upstream and downstream of the point of diversion. Consumptive use is divided into three major categories: irrigation, municipal, and all others e.g., domestic, livestock. These uses are less than 100 percent consumptive. It is assumed the non-consumed part of a diversion is returned to the stream from which it was diverted. Consumptive use from irrigation is from estimates made by the US Geological Survey (Portland). Consumption from other uses is based on the associated water rights. In these cases, consumptive use is obtained by multiplying the maximum diversion rate allowed for the water right by a consumptive use coefficient. Consumptive use diminishes availability both upstream and downstream of the point of diversion. There are two types of in-stream demands: in-stream water rights and scenic waterway flows. In-stream demands diminish availability upstream only. Because they are non-consumptive, they do not diminish stream flow downstream as do consumptive uses. Water availability has been calculated for over 2500 WABs. In general, the calculation of water availability at one WAB cannot be considered in isolation from other WABs in the same stream system. For water to be available at any given upstream point, it must be available at all points of calculation downstream.

  	Citation × Citation Citation Abstract Copy Title: Hot Dry Rock Geothermal Energy Development Program, Annual Report, Fiscal Year 1979 Author: Cremer, G.M. (comp.) Year: 1980 The Fenton Hill Project is still the principal center for developing methods, equipment, and instrumentation for creating and utilizing HDR geothermal reservoirs. The search for a second site for a similar experimental system in a different geological environment has been intensified, as have the identification and characterization of other HDR areas that may prove suitable for either experimental or commercial development.

Environmental monitoring of the Fenton Hill area continued through FY79. The environmental studies indicate that the hot dry rock operations have caused no significant environmental impact. Other supporting activities included rock physics, rock mechanics, fracture mapping, and instrumentation development. Two closely related activities - evaluation of the potential HDR energy resource of the US and the selection of a site for development of a second experimental heat-extraction system generally similar to that at Fenton Hill - have resulted in the collection of geology, hydrology, and heat-flow data on some level of field activity in 30 states. The resource-evaluation activity included reconnaissance field studies and a listing and preliminary characterization of US geothermal areas in which HDR energy extraction methods may be applicable.

S.; Sargent, Kenneth A.; Reed, J. E. Year: 2008, 2005 SUMMARY The U.S. Geological Survey's program for geologic and hydrologic evaluation of physiographic provinces to identify areas potentially suitable for locating repository sites for disposal of high-level nuclear wastes was announced to the Governors of the eight States in the Basin and Range Province on May 5, 1981. Representatives of Arizona, California, Idaho, New Mexico, Nevada, Oregon, Texas, and Utah, were invited to cooperate with the Federal Government in the evaluation process. Each Governor was requested to nominate an Earth scientist to represent the State in a province working group composed of State and U.S. Geological Survey representatives. This report, Part I of a three-part report, provides the background, introduction and scope of the study. This part also includes a discussion of geologic and hydrologic guidelines that will be used in the evaluation process and illustrates geohydro-logic environments and the effect of individual factors in providing multiple natural barriers to radionuclide migration. Part II is a reconnaissance characterization of the geologic and hydrologic factors to be used in the initial screening of the Basin and Range Province. Part III will be the initial evaluation of the Province and will identify regions that appear suitable for further study. The plan for study of the Province includes a stepwise screening process by which successively smaller land units are considered in increasing detail. Each step involves characterization of the geology and hydrology and selection of subunits for more intensive characterization. Selection of subunits for further study is by evaluation of geologic and hydrologic conditions following a set of guidelines. By representation on the Province Working Group, the States participate in a consultation and review role in: (1) Establishing geologic and hydrologic guidelines, and (2) characterizing and evaluating the Province. The States also participate in compilation of geologic and hydrologic data used in characterizing the Province. The current (1983) needs for a high-level radioactive waste repository include: (1) Disposal in a mined repository; (2) re- trievability of the waste for as much as 50 years; and (3) confidence of isolation of the waste from the accessible environment. Isolation of the waste needs to be assured using geologic and hydrologic conditions that: (1) Minimize risk of inadvertent future intrusions by man; (2) minimize the possibility of disturbance by processes that would expose the waste or increase its mobility; and (3) provide a system of natural barriers to the migration of waste by ground water. The guidelines adopted by the Province Working Group are designed to provide a standard with which these conditions can be compared. The guidelines can be grouped into four principal categories: (1) Potential host media, (2) ground-water conditions, (3) tectonic conditions, and (4) occurrence of natural resources. Ideally the host medium constitutes the first natural barrier to migration of radionculides. The host medium ideally should be a rock type that prevents or retards dissolution and transport of radionuclides. Rocks in both the saturated and unsaturated zones may have desirable characteristics for host media. Rocks?other than the host?in the ground-water flow path from the repository ideally should be major barriers to radionuclide migration. Confining beds of low permeability might be present to retard the rate of flow between more permeable beds. Additionally, sorption of radionuclides by materials such as clays and zeolites in the flow path can further retard the flow of radionuclides by several orders of magnitude. Tectonic conditions in an area should not present a probable cause for exhumation or increased mobility of radioactive waste. Natural resources are a factor for consideration because of the problem of future human intrusion and exposure to radioactivity in the quest for minerals, oil, gas, water, and geothermal resources. The ultimate evaluation of the suitability of a geohydrologic environment for developing a mined repository needs to assess all geologic and hydrologic characteristics and their interaction in providing confidence that a geohydrologic environment will effectively isolate radionuclides from human access. Several hypothetical settings with typical geohydrologic conditions in the Basin and Range Province are used to illustrate the effect of multiple barriers in the isolation of radionuclides.

A confined water body, occurring in volcanic rocks underlying the lake deposits yields large quantities of water to three wells in the study area. Dissolved-solids content of ground water generally increases in proportion to the thickness of lake deposits penetrated and to proximity of the lake deposits. Water from wells drilled in the volcanic rocks several miles from the lake deposits, and from wells penetrating the confined water body in volcanic rocks underlying the lake deposits contains small to moderate quantities of dissolved solids. Ground-water supplies can be developed almost anywhere in the study area by drilling wells to depths below the water table.

(Annett Brigitte), 1970- Year: 2008 Klamath River Water Quality and Acoustic Doppler Current Profiler Data from Link River Dam to Keno Dam, 2007 By Annett B. Sullivan, Michael L. Deas, Jessica Asbill, Julie D. Kirshtein, Kenna Butler, Roy E. Wellman, Marc A. Stewart, and Jennifer Vaughn Abstract In 2007, the U.S. Geological Survey, Watercourse Engineering, and Bureau of Reclamation began a project to construct and calibrate a water quality and hydrodynamic model of the 21-mile reach of the Klamath River from Link River Dam to Keno Dam. To provide a basis for this work, data collection and experimental work were planned for 2007 and 2008. This report documents sampling and analytical methods and presents data from the first year of work. To determine water velocities and discharge, a series of cross-sectional acoustic Doppler current profiler (ADCP) measurements were made on the mainstem and four canals on May 30 and September 19, 2007. Water quality was sampled weekly at five mainstem sites and five tributaries from early April through early November, 2007. Constituents reported here include field parameters (water temperature, pH, dissolved oxygen concentration, specific conductance); total nitrogen and phosphorus; particulate carbon and nitrogen; filtered orthophosphate, nitrite, nitrite plus nitrate, ammonia, organic carbon, iron, silica, and alkalinity; specific UV absorbance at 254 nm; phytoplankton and zooplankton enumeration and species identification; and bacterial abundance and morphological subgroups. The ADCP measurements conducted in good weather conditions in May showed that four major canals accounted for most changes in discharge along the mainstem on that day. Direction of velocity at measured locations was fairly homogeneous across the channel, while velocities were generally lowest near the bottom, and highest near surface, ranging from 0.0 to 0.8 ft/s. Measurements in September, made in windy conditions, raised questions about the effect of wind on flow. Most nutrient and carbon concentrations were lowest in spring, increased and remained elevated in summer, and decreased in fall. Dissolved nitrite plus nitrate and nitrite had a different seasonal cycle and were below detection or at low concentration in summer. Many nutrient and carbon concentrations were similar at the top and bottom of the water column, though ammonia and particulate carbon showed more variability in summer. Averaged over the season, particulate carbon and particulate nitrogen decreased in the downstream direction, while ammonia and orthophosphate concentrations increased in the downstream direction. At most sites, bacteria, phytoplankton, and zooplankton populations reached their maximums in summer. Large bacterial cells made up most of the bacteria biovolume, though cocci were the most numerous bacteria type. The cocci were smaller than the filter pore sizes used to separate dissolved from particulate matter in this study. Phytoplankton biovolumes were dominated by the blue-green alga Aphanizomenonflos aquae most of the sampling season, though a spring diatom bloom occurred. Phytoplankton biovolumes were generally highest at the upstream Link River and Railroad Bridge sites and decreased in the downstream direction. Zooplankton populations were dominated by copepods in early spring, and by cladocerans and rotifers in summer, with rotifers more common farther downstream. l Title: Klamath River water quality and acoustic Doppler current profiler data from Link River Dam to Keno Dam, 2007 Author: Sullivan, Annett B.

Isozyme analysis was not determined to be an adequate method for assessing stock structure in green sturgeon for the following reasons: 1) the complex nature of isozyme expression 2) the relatively poor resolution of enzyme systems for our samples 3) the invasive nature of collecting tissue samples for isozyme analysis, which necessitates sacrificing the fish, precludes collection of samples from some rivers. The stomach contents of 23 green sturgeon collected from fish harvested in the Klamath River were analyzed. Only four stomachs contained identifiable food items, with the others containing food far too digested for identification, gravel, or no contents. Two stomachs contained the small gastropod, Olivellapyna, one stomach contained the carapace remains of a female Dungeness crab, Cancer magister, and one stomach contained the posterior portions of three ammocoetes, Lampetra tridentata. Preliminary analysis was conducted using mtDNA to assess the potential of using this technique for assessing the stock structure of green sturgeon. Although the Klamath River Fishery Restoration Program did not fund this analysis, the results are presented because this work was designed to yield complementary information to the isozyme study. No diagnostic differences were detected between samples collected from the Klamath River and the Columbia River estuary using Restriction Fragment Length Polymorphism analysis. Study results indicated that microsateliite DNA analyst might be the most appropriate current genetic technique for assessing the population structure of green sturgeon.

  	Citation × Citation Citation Abstract Copy Title: Conservation plan, Miller Lake lamprey, Lampetra (Entosphenus) minima : April, 2005 Author: U.S. Fish and Wildlife Service Year: 2005 Public Review Draft 4- 27- 05 Conservation Plan Miller Lake Lamprey, Lampetra ( Entosphenus) minima April, 2005 Executive summary - The Miller Lake Lamprey was believed extinct after a chemical treatment in 1958, targeting lamprey and tui chub, extirpated both from Miller Lake. The lamprey population was later recognized to be a distinct species, Lampetra minima ( Bond and Kan 1973). It was the smallest lamprey species in the world ( maturing at less than 4 in), and at that time was known only from Miller Lake, where it was extinct In 1992, a small lamprey caught in the Upper Williamson River was identified as a Miller Lake Lamprey, and subsequent investigations have identified six local populations of this lamprey in two small subdrainages of the Upper Klamath Basin. Management strategies to preserve this species include: conserving appropriate habitat conditions and availability within the natural range of the Miller Lake Lamprey, addressing potential impacts from stocking streams with hatchery fish, reducing entrainment, and establishing connectivity within and between local populations. A man- made barrier built in 1959 still exists on Miller Creek. Originally created to prevent the re- establishment of lamprey in Miller Lake after the chemical treatment, the barrier currently prevents natural dispersal of the Miller Creek population and re- colonization of both extensive habitat in upper Miller Creek and Miller Lake itself. Removal of the barrier, which is in disrepair but continues to exclude lamprey, is feasible and will eliminate the only man- made feature obstructing natural connectivity within the Miller Lake drainage, the species' type locality. This conservation plan is intended to provide guidance for management actions and conservation of the Miller Lake Lamprey. Introduction lhe Miller Lake Lamprey, Lampetra { Entosphenus) minima, is the worlds smallest predatory lamprey, reaching a size of only 3- 6", and is endemic to the Klamath Basin ( Bond and Kan 1973, Gill et al. 2003, Lorion et al. 2000). It is also one of the few species to have " recovered" from extinction. Miller Lake was chemically treated with toxaphene by the Oregon Game Commission on September 16,1958 to eliminate Tui Chub ( Siphateles bicolor) and a population of unidentified lamprey ( Gerlach 1958, Gerlach and Borovicka 1964). The lamprey in Miller Lake was later discovered to have been a unique species, apparently restricted in range to the Miller Lake drainage ( a small, disjunct tributary to the Upper Williamson River), and was scientifically described by Bond and Kan ( 1973) fifteen years subsequent to its presumed extirpation. Public Review Draft 4- 27- 05 Although there appear to be no immediate threats to the Miller Lake Lamprey ( Kostow 2002), the species is of considerable conservation concern due to: 1) its relatively limited range in two small sub drainages of the Klamath Basin, 2) its continued absence in the ecologically unique setting of Miller Lake ( type locality) and 3) its evolutionary distinctiveness as the smallest known predatory lamprey in the world, maturing at less than four inches. Life History Distribution - The Miller Lake Lamprey is currently known from only two small sub- drainages of the Upper Klamath Basin, the upper Williamson River and the upper Sycan River above Sycan Marsh ( Lorion et al. 2000). The upper Williamson River contains four known populations ( Miller Creek, Jack Creek, Klamath Marsh, and mainstem Williamson River above the marsh). Miller Creek, which drains Miller Lake, is within the upper Williamson Watershed, but it goes sub- surface in the pumice soils and does not reach the Klamath Marsh or Williamson River. Miller Lake has presumably been isolated from the rest of the drainage since the eruption of Mt. Mazama ( Crater Lake) over 6,000 years ago. Jack Creek, a small northern tributary to the upper Williamson River, is also generally disjunct from the mainstem Williamson River due to low, intermittent surface flows in its lower reaches. The Upper Sycan drainage ( a northern tributary of the Sprague River) contains two principal populations, Long Creek drainage and the upper Sycan River drainage above Sycan Marsh. Lamprey have been documented in Coyote Creek and Shake Creek above Sycan Marsh by Nature Conservancy. Lamprey in Shake Creek have not been identified to species. Geographic Variability - In general, individuals from the modern Williamson and Sycan sub-drainages are morphologically similar ( Lorion et al. 2000). However, there are indications of geographic differences between populations. The Sycan populations exhibit significantly higher variability in the number of bicuspid posterial teeth, and the Miller Creek population generally tend to be darker on their ventral surface. Specimens from the original Miller Lake population ( pre- 1958) had, on average, fewer anterial teeth. They also tended to have larger eyes and oral disks relative to total length when compared to modern populations; however, this appears to be due to their slightly smaller size. The available genetic information also indicates that there are geographic differences in the mitochondrial genome ( mtDNA) between Sycan ( Sprague) and Williamson lamprey populations, with one haplotype found only in the Upper Sycan and another limited to lamprey populations in the Sprague River drainage ( Lorion et al. 2000). Continued genetic work on the Klamath lamprey fauna, examining additional genes, indicates that the population of lamprey in Miller Creek may be genetically different than both the other upper Williamson and Sycan populations ( Docker pers. com. 2004). Habitat - Miller Lake Lampreys currently occupy relatively cool, clear streams ( Gunckel and Reid 2004, Kan and Bond 1981, Lorion et al. 2000, Reid pers. com. 2004). Adults are generally associated with structural cover, including loose rocks and woody debris. In lower Miller Creek, where rocky habitat is limited, adult lampreys were consistently found in woody debris jams and even under seat boards from an old outhouse that had fallen into the creek ( Reid pers. obs. 1998). Ammocoetes ( a larval stage lasting about 5 years) live in the substrate and are generally Public Review Draft 4- 27- 05 associated with depositional environments. In streams, ammocoetes are frequently found in silty backwater areas, low energy stream edges, and in pool eddies where leaf litter and other organics ( including adult lamprey carcasses) tend to accumulate. At night ammocoetes may move into the water column to disperse downstream or into more favorable habitat. In Miller Lake ammocoetes were found in organic detritus all along the shoreline but rarely in the extremely cold tributaries flowing into the lake ( Kan and Bond 1981). Recent extensive collections of Pacific Lamprey ammocoetes along the coast indicate that ammocoetes do not occupy otherwise apparently suitable sediments if the upper layer is poorly oxygenated ( Reid and Goodman pers. obs. 2004). Reproduction - Miller Lake Lampreys spawn in shallow redds in clean gravels and sand, which are moved out of the redd by lamprey sucking onto small rocks and actively moving them out of the way ( Markle pers. com. 2004, Reid pers. com. 2004). In streams, redds are generally made in shallow water, often at the tail of a pool or run, and are roughly 10 cm in diameter and a few centimeters deep. In Miller Lake, lampreys were observed spawning in water as deep as 20 feet ( Cochrun 1951b, Kan and Bond 1981). Males attach to the female's head and wrap around her body, aligning genitals and allowing fertilization of the eggs as they emerge. Eggs are heavier than water and are mixed into the bottom of the redd by spawning actions. Kan and Bond ( 1981) found that female lampreys from Miller Lake contained an average of about 600 eggs. Time to hatching is not known, but is probably on the order of a few weeks. Larvae ( ammocoetes) emerge at about 8 mm and move into fine sediments. Adults die after spawning. Feeding - Miller Lake Lampreys feed on fish only as adults. Ammocoetes have no eyes or teeth and are purely filter feeders, burrowing in the sediment and feeding on suspended microorganisms and algae. The ammocoete phase lasts about five years, during which time the ammocoetes grow to around 150 mm. After transformation, adults enter a predatory phase before spawning that generally lasts for less than a year ( from transformation in the summer/ fall to spawning in summer of the following year). Adults feed primarily on flesh that is gouged and rasped out of a small wound (<= 11 mm) under the sucking disk ( Cochran 1994, Kan and Bond 1981). Adults apparently show little selectivity for prey. The adult lampreys in Miller Lake historically fed on both tui chubs and available salmonids ( rainbow, brook and juvenile brown trout) in Miller Lake ( Kan and Bond 1981). They also scavenged dead tui chubs and trout, as well as cannibalizing other lampreys. In Miller Creek, most recent observations found occasional lamprey wounds on brook trout, which were the most abundant species in the creek, but it is probable that lampreys also feed on both rainbows and young brown trout in the creek ( S. Reid pers. obs. 1998). In Jack Creek lampreys feed on speckled dace, the only other fish present in the stream, and in the Upper Sycan they feed on both trout and dace. Unlike other predatory lampreys, but similar to non- feeding brook lampreys, adult Miller Lake Lampreys loose body length and mass between the time they transform and actual spawning, indicating that energetic needs and gonadal development are not compensated for by the amount of food they consume ( Hubbs 1971, Kan and Bond 1981, Lorion et al. 2000). Lamprey / Trout Interaction - Although there have been no direct studies of the ecological interaction between lampreys and trout in the Klamath Basin, it is notable that healthy trout and lamprey populations coexist throughout the basin. Lampreys certainly prey on trout, and both adult lampreys and ammocoetes may represent a significant food resource to piscivorous adult Public Review Draft 4- 27- 05 trout. Native redband trout co- exist with much larger predatory lampreys (" Klamath Lake Lamprey", Lampetra { Entosphenus) sp., and Klamath River Lamprey, L. ( E.) similis) in Upper Klamath Lake. A large percentage of the trophy redband trout in Upper Klamath Lake, as well as both redband and brown trout in the Wood and Williamson Rivers, exhibit recent or healed lamprey scars. In smaller streams where Miller Lake Lampreys ( length 3- 6 in) co- exist with native and introduced trout ( redband, bull, brook and brown trout), there appears to be little impact to adult trout, and local fishermen are rarely even aware of the presence of the lamprey ( S. Reid, pers. comm. 2004, R. Smith, pers. comm. 2004). Surveys by USFWS and USFS in 1998- 1999 found that very few of the trout in Miller Creek, the Williamson or upper Sycan Rivers had scars, and during extensive snorkeling surveys, only a few trout were actually observed with lampreys attached ( S. Reid USFWS pers. com., 2004). Historical reports from Miller Lake prior to the extirpation of lampreys indicate that tui chubs were the principal prey, and dead tui chubs were often reported ( Cochrun 1951a, b, Gerlach 1958, Kan 1975, Kan and Bond 1981). Some cannibalism on other lampreys, as well as scavenging of dead fish carcasses, was also observed ( Kan and Bond 1981). Specific mortality of adult trout was not reported, although large trout were noted to have collections of scars and some mortality of fingerlings was observed. Recent observations of occasional fingerling trout mortality and much more frequent lethal predation on speckled dace (< 10 cm TL) in the Sycan River and Jack Creek, as well as the observation of apparently healthy adult trout with healed wounds, suggests that lethal predation on trout is generally limited to fingerlings ( Markle pers. com. 2004, Reid pers. com. 2004, Smith pers. com. 2004). It is not believed that predation on Miller Lake lamprey by piscivorous adult trout has been a threat to the sustainability of lamprey populations. These populations have co- evolved with native trout and appear to be productive enough to withstand some level of predation. The Jack Creek population is an exception. Jack Creek is believed to only support populations of Miller Lake lamprey and speckled dace. Since this lamprey population evolved absent predation from trout, there is a concern that an introduction of piscivorous adult trout could upset the ecological balance in Jack Creek and present a threat to both the lamprey and dace populations. For this reason, stocking of hatchery fish is prohibited by rule in Jack Creek or other streams containing Miller Lake lamprey. Miller Lake Fisheries - Miller Lake currently supports a recreational trout fishery of entirely introduced species. Miller Lake's one notable native species, the Miller Lake Lamprey, was thought extinct when the Oregon Department of Fish and Wildlife Commission approved the current Klamath Basin Fish Management Plan ( ODFW 1997). Today, Miller Lake provides a popular " catchable" and fingerling rainbow trout program, a trophy brown trout fishery, and an under- utilized kokanee population of small- sized individuals ( Smith pers. com. 2004). Due to the role of Miller Lake as a recreational fishery and concerns over the potential impact of lampreys on introduced trout populations in the lake, the history and status of Miller Lake fisheries are summarized below by species. Rainbow trout fingerlings ( 2- 4 inches) were planted in Miller Lake until 1948, when stocking was discontinued due to poor returns. At that time, the poor rainbow fishery was believed to have been due to lamprey predation and competition with resident tui chubs ( Cochrun 1950, Public Review Draft 4- 27- 05 1951a). However, based on the reported poor performance of stocked fingerling rainbows post-treatment ( see below), without either lampreys or tui chubs, it appears that local habitat conditions, and not trophic competition with tui chub or parasitism by lamprey, were driving the poor rainbow population dynamics. Recent observations by ODFW biologists have indicated that while the rainbow trout in Miller Lake are surviving, growing and being harvested by anglers, survival and growth have been, at best, marginal ( Smith pers. com. 2004). Trapnet samples in Miller Lake have been very inefficient at capturing older age class rainbow trout so the average size of sampled trout is not representative of the fish that are available for angler harvest. While trapnet sets typically made in the fall are not particularly good indicators of the rainbow population in Miller Lake, Trapnet sampling of rainbow trout documented an average length of approximately 8 inches in 1988 and approximately 4 inches in 1997. The release of catchable- sized rainbow trout into Miller Lake was initiated in 2001 to supplement the ongoing fingerling stocking program. Brown trout were first introduced into Miller Lake in 1981 and have been stocked annually since. Although small numbers may have been present prior to treatment. Survival and growth of brown trout has been excellent ( Smith pers. com. 2004). Brown trout averaged approximately 17 inches in length in 1998 and approximately 16 inches in 2001. Larger fish captured in trap net sets exceed 10 pounds. Miller Lake was identified by sport- fishing author Denny Rickards as one of the top ten brown trout producing lakes in the western United States. Lampreys themselves, as well as their impaired prey, might in turn serve as additional prey for the large, highly piscivorous brown trout. Stocks of kokanee were introduced to Miller Lake from several states between 1964 and 1971 ( all post- treatment). Kokanee have been very successful reproducing and stocking has not been necessary since 1971. The average size of maturing adults have remained relatively small. Miller Lake is an oligotrophic lake with very low productivity ( Johnson et al. 1985). The length of maturing female kokanee ranged between 7.5- 10 inches between 1965 tol972, and the average size of kokanee females in 2001 was approximately 8 inches. Based on the relatively small length of maturing kokanee females, it appears that environmental conditions or interspecific competition with other trout are driving the kokanee population dynamics. Brook trout were stocked in Miller Lake from the 1930' s until 1948. Brook trout were present in Miller Creek and apparently survived in tributaries during the 1958 treatment, since seven brook trout ( 6- 14 in) were gill- netted from the lake in 1964, prior to introduction of 85,000 kokanee and 150,000 rainbow fingerlings. No brook trout are currently stocked into the lake or tributaries of the lake. A healthy self- sustaining population of brook trout is currently present in Miller Creek, below the lamprey barrier, where they have apparently coexisted with lampreys since both recovered from the 1958 treatment. Tui chubs were present in Miller Lake prior to the 1958 treatment. It is not known whether tui chub were a native or introduced population. However, based on the elevation and atypical tui chub habitat in the lake, it is believed to have been an un- authorized introduction, most probably as a baitfish. Trophic competition between tui chub and rainbow trout has been consistently demonstrated in several Oregon lakes, including Diamond Lake in Douglas County. Tui chub or " roach" problems in Miller Lake were identified by Ken Cochrun ( Fisheries Agent, Oregon State Public Review Draft 4- 27- 05 game Comm.) in his 1950 and 1951 annual reports ( Cochrun 1950, 1951a). However, Mr. Cochrun felt that the " large population" of tui chub would be relatively easy to control compared to the lamprey and hence the need for the radical chemical treatment with toxaphene, which would eliminate both species, rather than rotenone, which would have limited effect on the lamprey ammocoetes in the substrate. In the 1950' s, as is still the case, considerable amount of time was expended by fishery districts controlling tui chub (" roach"), as noted in Mr. Cochrun's annual reports. Tui chubs were never restocked after the treatment and are no longer present in the Miller Lake drainage. One of the goals of this conservation plan for the Miller Lake Lamprey is to re- establish a lamprey population in Miller Lake itself. Historical reports from Miller Lake prior to the extirpation of lampreys nowhere mention specific mortality of adult trout, even when lamprey were abundant, although large trout were noted to have collections of scars ( see above - Lamprey/ Trout Interaction). Based on historical accounts and recent observations from the Upper Sycan drainages, mortality when observed has been on small fish (< 10cm TL). Observations from Miller Lake in the past and recent observations of trophy redband trout fisheries in Upper Klamath Lake indicate that little to no effect is experienced by the fish based on the occurrence of healed lamprey scars. Self- sustaining populations of brown and brook trout ( unstocked) currently coexist with lampreys in Miller Creek below the lamprey barrier. Were lamprey to become reestablished in Miller Lake, they would probably feed primarily on juvenile kokanee, which are abundant in the lake. Although lamprey predation on adult trout may result in some stress and condition loss, the principal effect on adult kokanee and trout fisheries in Miller Lake is likely to be aesthetic, with small round wounds (< l/ 2 in), or scars, on the side of fish. Future Recreational Fish Management The recreational trout and kokanee salmon fisheries in Miller Lake are an extremely valuable fish resource to local community and anglers. All efforts will be made by the Oregon Department of Fish and Wildlife to continue to offer angling recreation at current harvestable levels. In the unlikely event that the re- establishment of the Miller Lake lamprey adversely impacts the trout and kokanee population abundance, then additional fish stocking or other compatible management actions will be initiated as necessary to meet recreational fishery management objectives. Conservation Plan Note: Underlined, bold text in italics represents those portions of the conservation plan that are proposed to be adopted into Oregon Administrative Rule by the Oregon Fish and Wildlife Commission. Purpose This conservation plan is intended to provide guidance for management actions and conservation of the Miller Lake lamprey, Lampetra ( Entosphenus) minima. This is the first step in securing populations that currently exist in the Klamath Basin and in Public Review Draft 4- 27- 05 determining their status, abundance, distribution, and life history needs. As new information on the lamprey becomes available it is expected that this document will be modified and updated to reflect the current state of our knowledge. Species Management Unit and Population Description The Miller Lake Lamprey species management unit is comprised of six documented populations and one uncertain population. They are: • Mainstem Upper Williamson River above Klamath Marsh • Miller Creek • Jack Creek • Sycan River above Sycan Marsh • Long Creek • Coyote Creek • Shake Creek ( lamprey present have not been identified to species) Desired Status The desired status of the Miller Lake lamprey is for the species to be distributed widely throughout its historic range, with populations robust enough to withstand stochastic environmental events, and with both the populations and their habitat secure from anthropogenic threats. Current Status The Miller Lake Lamprey is endemic to the Klamath Basin and was recently re- described ( Lorion et al 2000). It is currently known from two sub- drainages. The Williamson River sub- drainage includes populations in Miller Creek, Jack Creek, Klamath Marsh and the mainstem upper Williamson River. In the Sycan sub- drainage the lamprey exists in Long Creek and in the upper Sycan River above the Sycan Marsh. Information regarding the abundance and population structure of Miller Lake lamprey in these systems is not available, and only anecdotal information is available for the life history or habitat requirements of the species. For detailed information on the current information available for the species see Life History section. No immediate threats to the Miller Lake Lamprey are known to currently exist, except for the barrier to connectivity between Miller Creek and Miller Lake. Public Review Draft 4- 27- 05 Management Strategies The short- and long- term management strategies for the Miller Lake Lamprey species management unit are: Short- term Strategy a) Re- establish connectivity to Miller Lake. Long- term Strategies b) Ensure appropriate habitat conditions and availability within the natural range of Miller Lake lamprey. c) Reduce entrainment or the potential for entrainment of adult and larval lampreys into water diversions. d) Reduce stranding or the potential for stranding of larval lampreys in dewatered segments of streams below water diversions. e) Maintain unobstructed opportunities, within and among populations for genetic exchange, natural dispersal or migration activities, and re- colonization of unoccupied portions of historical habitat. f) No hatchery fish shall be stocked in streams that support Miller Lake lamprey. Management strategies are those general conditions relevant to the conservation of the species that are considered essential to ensure its long- term survival within its natural range. Although there are many aspects of a species life- history and management that may play a role in the species' biology, the management strategies include those aspects that are currently considered to be both essential for its long- term survival and that are potentially at risk. Conservation Actions Conservation actions are those specific activities or projects that have been identified as appropriate for the realization of the above conservation goals. General - Due to the general lack of information about the life- history, habitat requirements, and distribution of the Miller Lake Lamprey, any studies which increase our understanding of the species will contribute to future conservation planning and should be supported. Habitat - At this time, the general habitat requirements of the Miller Lake Lamprey populations in the upper Williamson and upper Sycan drainages appear to be similar to those of the native trout populations, and habitat restoration or enhancement projects that benefit the trout populations should be beneficial to the lamprey as well. However, there may be specific differences between these species that should be considered in future projects as our understanding of the lamprey's life- history increases. Public Review Draft 4- 27- 05 Entrainment - At this time there has been no evaluation of potential entrainment risks to the Miller Lake Lamprey. Unscreened or improperly screened irrigation diversions currently exist on the upper Sycan and upper Williamson River systems. Private irrigator participation into the screening program should continue to be encouraged and supported. Stranding - At this time there has been no evaluation of potential stranding risks to the Miller Lake Lamprey. Current water diversions reduce the stream flow in segments of the streams directly below the diversion point. Minimum stream flows or gradual ramping strategies should be encouraged where practicable. Connectivity - The Miller Lake Lamprey is not known to carry out extensive spawning migrations. However, due the tendency for ammocoetes to drift downstream during the multi- year larval stage, it is essential that local populations have free upstream passage opportunities during the period when adults are residing in the stream. The swimming characteristics and passage capabilities of trout ( for whom many fish ladders are designed) and lamprey are very different. Lamprey- friendly ladders or passage corridors should be encouraged in the design phase of new projects, and occupied lamprey streams should be evaluated for the presence of older fish ladders, as well as other artificial barriers. Re- establishment of the Miller Lake population - Miller Lake itself, the type locality for the species, remains the only known historical habitat from which the Miller Lake Lamprey is known to have been extirpated. It also represents both an ecologically unique habitat and a crucial component in the evolutionary legacy of the species. Following the extirpation of lampreys from Miller Lake in 1958, a lamprey barrier was constructed in Miller Creek to prevent recolonization of the lake from Miller Creek. The barrier remains in place today. Removal of this barrier should have a high priority in order to meet the conservation goals for the Miller Lake Lamprey and is discussed in more detail below. The barrier was constructed by the State of Oregon Game Commission in 1959 at the upstream extent of a short, high- gradient cascade in Miller Creek approximately 54 mile downstream from the outlet of Miller Lake and forest road 9772. It consists of a low stonework dam ( about 2 ft high) constructed of mortared native rocks, with a metal plate and lip bolted on top. The configuration is very effective as a man- made barrier to fish passage. However, the current condition of the concrete and rock structure is substantially deteriorated. A recent examination by ODFW, USFWS and USFS personnel indicates that the structure would be relatively easy to remove using hand tools without adverse instream impacts ( evaluated by R. Smith et al., September 2003). Recent baseline surveys ( August 2004) of lamprey ammocoetes in the Miller drainage indicate that they are apparently limited to less than two miles of low- gradient stream in lower Miller Creek ( Gunckel and Reid 2004). Allowing lampreys to re- establish a population above the cascade in Miller Creek and Miller Lake will aid in creating an additional buffer against stochastic events that could otherwise eradicate this geographically limited population. Additional surveys should be scheduled on a five- 10 Public Review Draft 4- 27- 05 year basis to evaluate status of the population and the success of re- colonization efforts. Removal of the barrier should allow natural expansion of the population and recolonization of the lake from the Miller Creek population, which survived the original extirpation. Information Gaps 1) Life history - very little quantitative information is available on the life history and habitat requirements of either ammocoetes or adults with which to guide management decisions. 2) Distribution - current understanding of distribution is based on surveys in the 1990' s that primarily focused on the Williamson and Sprague River drainages. Other potential areas in the Klamath Basin outside these drainages have not been properly surveyed. 3) No specific population or fine- scale distributional surveys have been undertaken for any populations outside of the Miller Lake drainage. 4) Preliminary morphological and genetic information suggests that there are regional differences between the various populations of Miller Lake Lamprey in the Klamath Basin. However, the available information is not yet sufficient for making management decisions relative to population independence or uniqueness. Strategies to Address Gaps 1) A Miller Lake Lamprey Technical Management Team has been formed to promote investigation, management and conservation of the Miller Lake Lamprey. This team currently consists of biologists from ODFW ( Roger Smith and Stephanie Gunckel), Oregon State University ( Douglas Markle), the Western Lamprey Project ( Stewart Reid), and the Great Lakes Inst. Environmental Research ( Margaret Docker - lamprey genetics). 2) ODFW will, where appropriate, incorporate lampreys into their fish survey protocols in the Klamath Basin and will seek to collaborate with other researchers carrying out lamprey surveys in the Basin. 3) ODFW and the Miller Lake Lamprey Technical Management Team will promote the investigation of morphological and genetic information informative to resolving regional differences between the various populations of Miller Lake Lamprey. 11 Public Review Draft 4- 27- 05 Research, Monitoring and Evaluation Research Promote scientific studies of the Miller Lake Lamprey to aid in the conservation of the Monitoring Where appropriate, incorporate lampreys into fish survey protocols in the Klamath Basin and seek to collaborate with other researchers carrying out lamprey surveys in the Basin. Evaluation Periodically evaluate the status of Miller Lake lamprey and the success of the conservation plan management strategies. Research - Due to the paucity of available quantitative information on the distribution, life history, habitat requirements of either ammocoetes or adults, ODFW will promote scientific studies of the Miller Lake Lamprey to aid in the conservation of the species. Monitoring - ODFW, in collaboration with USFWS, has documented baseline distribution of the fish in Miller Creek with the lamprey barrier in place ( Gunckel and Reid 2004). Monitoring of the population will continue to evaluate upstream movement, distribution, abundance, and re- colonization of the lake through the cooperative effort of ODFW and the Miller Lake Lamprey Technical Management Team. The ODFW and the Technical Management Team, will meet and discuss progress after the barrier has been removed, and the lampreys have had unobstructed passage to Miller Lake for five years. Adaptive Management a) A Miller Lake Lamprey Technical Management Team shall be formed. b) The Miller Lake Lamprey Technical Management Team shall meet periodically to review the success of the management actions identified in the Miller Lake Lamprey Conservation Plan and identify modifications to management actions that are needed to achieve the desired status for Miller Lake lamprey. No immediate threats to the Miller Lake Lamprey are known to currently exist, except for the barrier in Miller Creek. The Miller Lake Lamprey Technical Management Team ( see under Strategies to Address Gaps) has been formed to promote investigation, management and conservation of the Miller Lake Lamprey. The team will meet periodically to evaluate current status and management strategies in light of new information. 12 Public Review Draft 4- 27- 05 Current management action is proposed for removal of the Miller Creek Barrier. The lamprey population in Miller Creek will continue to be monitored by ODFW following the 2004 baseline surveys. After five years the Miller Lake Lamprey Technical Management Team will evaluate the status of the Miller Creek population and the success of natural re- colonization of Miller Lake. If sufficient progress has not been made, then discussions regarding active re- introduction of lampreys to the lake will be initiated. Trigger for Plan Modification Substantial negative changes in the distribution or abundance of the Miller Lake lamprey, or the recognition of new threats to the species, shall prompt a review of the species management unit's status and all Miller Lake Lamprey Conservation Plan management strategies by the Miller Lake Lamprey Technical Management Team. Appropriate modifications to the Miller Lake Lamprey Conservation Plan intended to better achieve the desired status identified in the Plan shall be proposed by the Miller Lake Lamprey Technical Management Team. Reporting a) The Miller Lake Lamprey Technical Management Team shall periodically report on the status of Miller Lake lamprey and the effectiveness of the management strategies identified in the Miller lake Lamprey Conservation Plan. b) Annual Miller Lake Lamprey data collected and any reports on the status of Miller Lake Lamprey or evaluations of the Miller Lake Lamprey Conservation Plan shall be made available to the public. The staff of the ODFW's Klamath Watershed District and Native Fish Research Project will periodically report monitoring and research results through native fish conservation strategy stock status reviews. 13 Public Review Draft 4- 27- 05 Citations Bond, C.

The lamprey population was later recognized to be a distinct species, Lampetra minima ( Bond and Kan 1973). It was the smallest lamprey species in the world ( maturing at less than 4 in), and at that time was known only from Miller Lake, where it was extinct In 1992, a small lamprey caught in the Upper Williamson River was identified as a Miller Lake Lamprey, and subsequent investigations have identified six local populations of this lamprey in two small subdrainages of the Upper Klamath Basin. Management strategies to preserve this species include: conserving appropriate habitat conditions and availability within the natural range of the Miller Lake Lamprey, addressing potential impacts from stocking streams with hatchery fish, reducing entrainment, and establishing connectivity within and between local populations. A man- made barrier built in 1959 still exists on Miller Creek. Originally created to prevent the re- establishment of lamprey in Miller Lake after the chemical treatment, the barrier currently prevents natural dispersal of the Miller Creek population and re- colonization of both extensive habitat in upper Miller Creek and Miller Lake itself. Removal of the barrier, which is in disrepair but continues to exclude lamprey, is feasible and will eliminate the only man- made feature obstructing natural connectivity within the Miller Lake drainage, the species' type locality. This conservation plan is intended to provide guidance for management actions and conservation of the Miller Lake Lamprey. Introduction lhe Miller Lake Lamprey, Lampetra { Entosphenus) minima, is the worlds smallest predatory lamprey, reaching a size of only 3- 6", and is endemic to the Klamath Basin ( Bond and Kan 1973, Gill et al. 2003, Lorion et al. 2000). It is also one of the few species to have " recovered" from extinction. Miller Lake was chemically treated with toxaphene by the Oregon Game Commission on September 16,1958 to eliminate Tui Chub ( Siphateles bicolor) and a population of unidentified lamprey ( Gerlach 1958, Gerlach and Borovicka 1964). The lamprey in Miller Lake was later discovered to have been a unique species, apparently restricted in range to the Miller Lake drainage ( a small, disjunct tributary to the Upper Williamson River), and was scientifically described by Bond and Kan ( 1973) fifteen years subsequent to its presumed extirpation. Public Review Draft 4- 27- 05 Although there appear to be no immediate threats to the Miller Lake Lamprey ( Kostow 2002), the species is of considerable conservation concern due to: 1) its relatively limited range in two small sub drainages of the Klamath Basin, 2) its continued absence in the ecologically unique setting of Miller Lake ( type locality) and 3) its evolutionary distinctiveness as the smallest known predatory lamprey in the world, maturing at less than four inches. Life History Distribution - The Miller Lake Lamprey is currently known from only two small sub- drainages of the Upper Klamath Basin, the upper Williamson River and the upper Sycan River above Sycan Marsh ( Lorion et al. 2000). The upper Williamson River contains four known populations ( Miller Creek, Jack Creek, Klamath Marsh, and mainstem Williamson River above the marsh). Miller Creek, which drains Miller Lake, is within the upper Williamson Watershed, but it goes sub- surface in the pumice soils and does not reach the Klamath Marsh or Williamson River. Miller Lake has presumably been isolated from the rest of the drainage since the eruption of Mt. Mazama ( Crater Lake) over 6,000 years ago. Jack Creek, a small northern tributary to the upper Williamson River, is also generally disjunct from the mainstem Williamson River due to low, intermittent surface flows in its lower reaches. The Upper Sycan drainage ( a northern tributary of the Sprague River) contains two principal populations, Long Creek drainage and the upper Sycan River drainage above Sycan Marsh. Lamprey have been documented in Coyote Creek and Shake Creek above Sycan Marsh by Nature Conservancy. Lamprey in Shake Creek have not been identified to species. Geographic Variability - In general, individuals from the modern Williamson and Sycan sub-drainages are morphologically similar ( Lorion et al. 2000). However, there are indications of geographic differences between populations. The Sycan populations exhibit significantly higher variability in the number of bicuspid posterial teeth, and the Miller Creek population generally tend to be darker on their ventral surface. Specimens from the original Miller Lake population ( pre- 1958) had, on average, fewer anterial teeth. They also tended to have larger eyes and oral disks relative to total length when compared to modern populations; however, this appears to be due to their slightly smaller size. The available genetic information also indicates that there are geographic differences in the mitochondrial genome ( mtDNA) between Sycan ( Sprague) and Williamson lamprey populations, with one haplotype found only in the Upper Sycan and another limited to lamprey populations in the Sprague River drainage ( Lorion et al. 2000). Continued genetic work on the Klamath lamprey fauna, examining additional genes, indicates that the population of lamprey in Miller Creek may be genetically different than both the other upper Williamson and Sycan populations ( Docker pers. com. 2004). Habitat - Miller Lake Lampreys currently occupy relatively cool, clear streams ( Gunckel and Reid 2004, Kan and Bond 1981, Lorion et al. 2000, Reid pers. com. 2004). Adults are generally associated with structural cover, including loose rocks and woody debris. In lower Miller Creek, where rocky habitat is limited, adult lampreys were consistently found in woody debris jams and even under seat boards from an old outhouse that had fallen into the creek ( Reid pers. obs. 1998). Ammocoetes ( a larval stage lasting about 5 years) live in the substrate and are generally Public Review Draft 4- 27- 05 associated with depositional environments. In streams, ammocoetes are frequently found in silty backwater areas, low energy stream edges, and in pool eddies where leaf litter and other organics ( including adult lamprey carcasses) tend to accumulate. At night ammocoetes may move into the water column to disperse downstream or into more favorable habitat. In Miller Lake ammocoetes were found in organic detritus all along the shoreline but rarely in the extremely cold tributaries flowing into the lake ( Kan and Bond 1981). Recent extensive collections of Pacific Lamprey ammocoetes along the coast indicate that ammocoetes do not occupy otherwise apparently suitable sediments if the upper layer is poorly oxygenated ( Reid and Goodman pers. obs. 2004). Reproduction - Miller Lake Lampreys spawn in shallow redds in clean gravels and sand, which are moved out of the redd by lamprey sucking onto small rocks and actively moving them out of the way ( Markle pers. com. 2004, Reid pers. com. 2004). In streams, redds are generally made in shallow water, often at the tail of a pool or run, and are roughly 10 cm in diameter and a few centimeters deep. In Miller Lake, lampreys were observed spawning in water as deep as 20 feet ( Cochrun 1951b, Kan and Bond 1981). Males attach to the female's head and wrap around her body, aligning genitals and allowing fertilization of the eggs as they emerge. Eggs are heavier than water and are mixed into the bottom of the redd by spawning actions. Kan and Bond ( 1981) found that female lampreys from Miller Lake contained an average of about 600 eggs. Time to hatching is not known, but is probably on the order of a few weeks. Larvae ( ammocoetes) emerge at about 8 mm and move into fine sediments. Adults die after spawning. Feeding - Miller Lake Lampreys feed on fish only as adults. Ammocoetes have no eyes or teeth and are purely filter feeders, burrowing in the sediment and feeding on suspended microorganisms and algae. The ammocoete phase lasts about five years, during which time the ammocoetes grow to around 150 mm. After transformation, adults enter a predatory phase before spawning that generally lasts for less than a year ( from transformation in the summer/ fall to spawning in summer of the following year). Adults feed primarily on flesh that is gouged and rasped out of a small wound (<= 11 mm) under the sucking disk ( Cochran 1994, Kan and Bond 1981). Adults apparently show little selectivity for prey. The adult lampreys in Miller Lake historically fed on both tui chubs and available salmonids ( rainbow, brook and juvenile brown trout) in Miller Lake ( Kan and Bond 1981). They also scavenged dead tui chubs and trout, as well as cannibalizing other lampreys. In Miller Creek, most recent observations found occasional lamprey wounds on brook trout, which were the most abundant species in the creek, but it is probable that lampreys also feed on both rainbows and young brown trout in the creek ( S. Reid pers. obs. 1998). In Jack Creek lampreys feed on speckled dace, the only other fish present in the stream, and in the Upper Sycan they feed on both trout and dace. Unlike other predatory lampreys, but similar to non- feeding brook lampreys, adult Miller Lake Lampreys loose body length and mass between the time they transform and actual spawning, indicating that energetic needs and gonadal development are not compensated for by the amount of food they consume ( Hubbs 1971, Kan and Bond 1981, Lorion et al. 2000). Lamprey / Trout Interaction - Although there have been no direct studies of the ecological interaction between lampreys and trout in the Klamath Basin, it is notable that healthy trout and lamprey populations coexist throughout the basin. Lampreys certainly prey on trout, and both adult lampreys and ammocoetes may represent a significant food resource to piscivorous adult Public Review Draft 4- 27- 05 trout. Native redband trout co- exist with much larger predatory lampreys (" Klamath Lake Lamprey", Lampetra { Entosphenus) sp., and Klamath River Lamprey, L. ( E.) similis) in Upper Klamath Lake. A large percentage of the trophy redband trout in Upper Klamath Lake, as well as both redband and brown trout in the Wood and Williamson Rivers, exhibit recent or healed lamprey scars. In smaller streams where Miller Lake Lampreys ( length 3- 6 in) co- exist with native and introduced trout ( redband, bull, brook and brown trout), there appears to be little impact to adult trout, and local fishermen are rarely even aware of the presence of the lamprey ( S. Reid, pers. comm. 2004, R. Smith, pers. comm. 2004). Surveys by USFWS and USFS in 1998- 1999 found that very few of the trout in Miller Creek, the Williamson or upper Sycan Rivers had scars, and during extensive snorkeling surveys, only a few trout were actually observed with lampreys attached ( S. Reid USFWS pers. com., 2004). Historical reports from Miller Lake prior to the extirpation of lampreys indicate that tui chubs were the principal prey, and dead tui chubs were often reported ( Cochrun 1951a, b, Gerlach 1958, Kan 1975, Kan and Bond 1981). Some cannibalism on other lampreys, as well as scavenging of dead fish carcasses, was also observed ( Kan and Bond 1981). Specific mortality of adult trout was not reported, although large trout were noted to have collections of scars and some mortality of fingerlings was observed. Recent observations of occasional fingerling trout mortality and much more frequent lethal predation on speckled dace (< 10 cm TL) in the Sycan River and Jack Creek, as well as the observation of apparently healthy adult trout with healed wounds, suggests that lethal predation on trout is generally limited to fingerlings ( Markle pers. com. 2004, Reid pers. com. 2004, Smith pers. com. 2004). It is not believed that predation on Miller Lake lamprey by piscivorous adult trout has been a threat to the sustainability of lamprey populations. These populations have co- evolved with native trout and appear to be productive enough to withstand some level of predation. The Jack Creek population is an exception. Jack Creek is believed to only support populations of Miller Lake lamprey and speckled dace. Since this lamprey population evolved absent predation from trout, there is a concern that an introduction of piscivorous adult trout could upset the ecological balance in Jack Creek and present a threat to both the lamprey and dace populations. For this reason, stocking of hatchery fish is prohibited by rule in Jack Creek or other streams containing Miller Lake lamprey. Miller Lake Fisheries - Miller Lake currently supports a recreational trout fishery of entirely introduced species. Miller Lake's one notable native species, the Miller Lake Lamprey, was thought extinct when the Oregon Department of Fish and Wildlife Commission approved the current Klamath Basin Fish Management Plan ( ODFW 1997). Today, Miller Lake provides a popular " catchable" and fingerling rainbow trout program, a trophy brown trout fishery, and an under- utilized kokanee population of small- sized individuals ( Smith pers. com. 2004). Due to the role of Miller Lake as a recreational fishery and concerns over the potential impact of lampreys on introduced trout populations in the lake, the history and status of Miller Lake fisheries are summarized below by species. Rainbow trout fingerlings ( 2- 4 inches) were planted in Miller Lake until 1948, when stocking was discontinued due to poor returns. At that time, the poor rainbow fishery was believed to have been due to lamprey predation and competition with resident tui chubs ( Cochrun 1950, Public Review Draft 4- 27- 05 1951a). However, based on the reported poor performance of stocked fingerling rainbows post-treatment ( see below), without either lampreys or tui chubs, it appears that local habitat conditions, and not trophic competition with tui chub or parasitism by lamprey, were driving the poor rainbow population dynamics. Recent observations by ODFW biologists have indicated that while the rainbow trout in Miller Lake are surviving, growing and being harvested by anglers, survival and growth have been, at best, marginal ( Smith pers. com. 2004). Trapnet samples in Miller Lake have been very inefficient at capturing older age class rainbow trout so the average size of sampled trout is not representative of the fish that are available for angler harvest. While trapnet sets typically made in the fall are not particularly good indicators of the rainbow population in Miller Lake, Trapnet sampling of rainbow trout documented an average length of approximately 8 inches in 1988 and approximately 4 inches in 1997. The release of catchable- sized rainbow trout into Miller Lake was initiated in 2001 to supplement the ongoing fingerling stocking program. Brown trout were first introduced into Miller Lake in 1981 and have been stocked annually since. Although small numbers may have been present prior to treatment. Survival and growth of brown trout has been excellent ( Smith pers. com. 2004). Brown trout averaged approximately 17 inches in length in 1998 and approximately 16 inches in 2001. Larger fish captured in trap net sets exceed 10 pounds. Miller Lake was identified by sport- fishing author Denny Rickards as one of the top ten brown trout producing lakes in the western United States. Lampreys themselves, as well as their impaired prey, might in turn serve as additional prey for the large, highly piscivorous brown trout. Stocks of kokanee were introduced to Miller Lake from several states between 1964 and 1971 ( all post- treatment). Kokanee have been very successful reproducing and stocking has not been necessary since 1971. The average size of maturing adults have remained relatively small. Miller Lake is an oligotrophic lake with very low productivity ( Johnson et al. 1985). The length of maturing female kokanee ranged between 7.5- 10 inches between 1965 tol972, and the average size of kokanee females in 2001 was approximately 8 inches. Based on the relatively small length of maturing kokanee females, it appears that environmental conditions or interspecific competition with other trout are driving the kokanee population dynamics. Brook trout were stocked in Miller Lake from the 1930' s until 1948. Brook trout were present in Miller Creek and apparently survived in tributaries during the 1958 treatment, since seven brook trout ( 6- 14 in) were gill- netted from the lake in 1964, prior to introduction of 85,000 kokanee and 150,000 rainbow fingerlings. No brook trout are currently stocked into the lake or tributaries of the lake. A healthy self- sustaining population of brook trout is currently present in Miller Creek, below the lamprey barrier, where they have apparently coexisted with lampreys since both recovered from the 1958 treatment. Tui chubs were present in Miller Lake prior to the 1958 treatment. It is not known whether tui chub were a native or introduced population. However, based on the elevation and atypical tui chub habitat in the lake, it is believed to have been an un- authorized introduction, most probably as a baitfish. Trophic competition between tui chub and rainbow trout has been consistently demonstrated in several Oregon lakes, including Diamond Lake in Douglas County. Tui chub or " roach" problems in Miller Lake were identified by Ken Cochrun ( Fisheries Agent, Oregon State Public Review Draft 4- 27- 05 game Comm.) in his 1950 and 1951 annual reports ( Cochrun 1950, 1951a). However, Mr. Cochrun felt that the " large population" of tui chub would be relatively easy to control compared to the lamprey and hence the need for the radical chemical treatment with toxaphene, which would eliminate both species, rather than rotenone, which would have limited effect on the lamprey ammocoetes in the substrate. In the 1950' s, as is still the case, considerable amount of time was expended by fishery districts controlling tui chub (" roach"), as noted in Mr. Cochrun's annual reports. Tui chubs were never restocked after the treatment and are no longer present in the Miller Lake drainage. One of the goals of this conservation plan for the Miller Lake Lamprey is to re- establish a lamprey population in Miller Lake itself. Historical reports from Miller Lake prior to the extirpation of lampreys nowhere mention specific mortality of adult trout, even when lamprey were abundant, although large trout were noted to have collections of scars ( see above - Lamprey/ Trout Interaction). Based on historical accounts and recent observations from the Upper Sycan drainages, mortality when observed has been on small fish (< 10cm TL). Observations from Miller Lake in the past and recent observations of trophy redband trout fisheries in Upper Klamath Lake indicate that little to no effect is experienced by the fish based on the occurrence of healed lamprey scars. Self- sustaining populations of brown and brook trout ( unstocked) currently coexist with lampreys in Miller Creek below the lamprey barrier. Were lamprey to become reestablished in Miller Lake, they would probably feed primarily on juvenile kokanee, which are abundant in the lake. Although lamprey predation on adult trout may result in some stress and condition loss, the principal effect on adult kokanee and trout fisheries in Miller Lake is likely to be aesthetic, with small round wounds (< l/ 2 in), or scars, on the side of fish. Future Recreational Fish Management The recreational trout and kokanee salmon fisheries in Miller Lake are an extremely valuable fish resource to local community and anglers. All efforts will be made by the Oregon Department of Fish and Wildlife to continue to offer angling recreation at current harvestable levels. In the unlikely event that the re- establishment of the Miller Lake lamprey adversely impacts the trout and kokanee population abundance, then additional fish stocking or other compatible management actions will be initiated as necessary to meet recreational fishery management objectives. Conservation Plan Note: Underlined, bold text in italics represents those portions of the conservation plan that are proposed to be adopted into Oregon Administrative Rule by the Oregon Fish and Wildlife Commission. Purpose This conservation plan is intended to provide guidance for management actions and conservation of the Miller Lake lamprey, Lampetra ( Entosphenus) minima. This is the first step in securing populations that currently exist in the Klamath Basin and in Public Review Draft 4- 27- 05 determining their status, abundance, distribution, and life history needs. As new information on the lamprey becomes available it is expected that this document will be modified and updated to reflect the current state of our knowledge. Species Management Unit and Population Description The Miller Lake Lamprey species management unit is comprised of six documented populations and one uncertain population. They are: • Mainstem Upper Williamson River above Klamath Marsh • Miller Creek • Jack Creek • Sycan River above Sycan Marsh • Long Creek • Coyote Creek • Shake Creek ( lamprey present have not been identified to species) Desired Status The desired status of the Miller Lake lamprey is for the species to be distributed widely throughout its historic range, with populations robust enough to withstand stochastic environmental events, and with both the populations and their habitat secure from anthropogenic threats. Current Status The Miller Lake Lamprey is endemic to the Klamath Basin and was recently re- described ( Lorion et al 2000). It is currently known from two sub- drainages. The Williamson River sub- drainage includes populations in Miller Creek, Jack Creek, Klamath Marsh and the mainstem upper Williamson River. In the Sycan sub- drainage the lamprey exists in Long Creek and in the upper Sycan River above the Sycan Marsh. Information regarding the abundance and population structure of Miller Lake lamprey in these systems is not available, and only anecdotal information is available for the life history or habitat requirements of the species. For detailed information on the current information available for the species see Life History section. No immediate threats to the Miller Lake Lamprey are known to currently exist, except for the barrier to connectivity between Miller Creek and Miller Lake. Public Review Draft 4- 27- 05 Management Strategies The short- and long- term management strategies for the Miller Lake Lamprey species management unit are: Short- term Strategy a) Re- establish connectivity to Miller Lake. Long- term Strategies b) Ensure appropriate habitat conditions and availability within the natural range of Miller Lake lamprey. c) Reduce entrainment or the potential for entrainment of adult and larval lampreys into water diversions. d) Reduce stranding or the potential for stranding of larval lampreys in dewatered segments of streams below water diversions. e) Maintain unobstructed opportunities, within and among populations for genetic exchange, natural dispersal or migration activities, and re- colonization of unoccupied portions of historical habitat. f) No hatchery fish shall be stocked in streams that support Miller Lake lamprey. Management strategies are those general conditions relevant to the conservation of the species that are considered essential to ensure its long- term survival within its natural range. Although there are many aspects of a species life- history and management that may play a role in the species' biology, the management strategies include those aspects that are currently considered to be both essential for its long- term survival and that are potentially at risk. Conservation Actions Conservation actions are those specific activities or projects that have been identified as appropriate for the realization of the above conservation goals. General - Due to the general lack of information about the life- history, habitat requirements, and distribution of the Miller Lake Lamprey, any studies which increase our understanding of the species will contribute to future conservation planning and should be supported. Habitat - At this time, the general habitat requirements of the Miller Lake Lamprey populations in the upper Williamson and upper Sycan drainages appear to be similar to those of the native trout populations, and habitat restoration or enhancement projects that benefit the trout populations should be beneficial to the lamprey as well. However, there may be specific differences between these species that should be considered in future projects as our understanding of the lamprey's life- history increases. Public Review Draft 4- 27- 05 Entrainment - At this time there has been no evaluation of potential entrainment risks to the Miller Lake Lamprey. Unscreened or improperly screened irrigation diversions currently exist on the upper Sycan and upper Williamson River systems. Private irrigator participation into the screening program should continue to be encouraged and supported. Stranding - At this time there has been no evaluation of potential stranding risks to the Miller Lake Lamprey. Current water diversions reduce the stream flow in segments of the streams directly below the diversion point. Minimum stream flows or gradual ramping strategies should be encouraged where practicable. Connectivity - The Miller Lake Lamprey is not known to carry out extensive spawning migrations. However, due the tendency for ammocoetes to drift downstream during the multi- year larval stage, it is essential that local populations have free upstream passage opportunities during the period when adults are residing in the stream. The swimming characteristics and passage capabilities of trout ( for whom many fish ladders are designed) and lamprey are very different. Lamprey- friendly ladders or passage corridors should be encouraged in the design phase of new projects, and occupied lamprey streams should be evaluated for the presence of older fish ladders, as well as other artificial barriers. Re- establishment of the Miller Lake population - Miller Lake itself, the type locality for the species, remains the only known historical habitat from which the Miller Lake Lamprey is known to have been extirpated. It also represents both an ecologically unique habitat and a crucial component in the evolutionary legacy of the species. Following the extirpation of lampreys from Miller Lake in 1958, a lamprey barrier was constructed in Miller Creek to prevent recolonization of the lake from Miller Creek. The barrier remains in place today. Removal of this barrier should have a high priority in order to meet the conservation goals for the Miller Lake Lamprey and is discussed in more detail below. The barrier was constructed by the State of Oregon Game Commission in 1959 at the upstream extent of a short, high- gradient cascade in Miller Creek approximately 54 mile downstream from the outlet of Miller Lake and forest road 9772. It consists of a low stonework dam ( about 2 ft high) constructed of mortared native rocks, with a metal plate and lip bolted on top. The configuration is very effective as a man- made barrier to fish passage. However, the current condition of the concrete and rock structure is substantially deteriorated. A recent examination by ODFW, USFWS and USFS personnel indicates that the structure would be relatively easy to remove using hand tools without adverse instream impacts ( evaluated by R. Smith et al., September 2003). Recent baseline surveys ( August 2004) of lamprey ammocoetes in the Miller drainage indicate that they are apparently limited to less than two miles of low- gradient stream in lower Miller Creek ( Gunckel and Reid 2004). Allowing lampreys to re- establish a population above the cascade in Miller Creek and Miller Lake will aid in creating an additional buffer against stochastic events that could otherwise eradicate this geographically limited population. Additional surveys should be scheduled on a five- 10 Public Review Draft 4- 27- 05 year basis to evaluate status of the population and the success of re- colonization efforts. Removal of the barrier should allow natural expansion of the population and recolonization of the lake from the Miller Creek population, which survived the original extirpation. Information Gaps 1) Life history - very little quantitative information is available on the life history and habitat requirements of either ammocoetes or adults with which to guide management decisions. 2) Distribution - current understanding of distribution is based on surveys in the 1990' s that primarily focused on the Williamson and Sprague River drainages. Other potential areas in the Klamath Basin outside these drainages have not been properly surveyed. 3) No specific population or fine- scale distributional surveys have been undertaken for any populations outside of the Miller Lake drainage. 4) Preliminary morphological and genetic information suggests that there are regional differences between the various populations of Miller Lake Lamprey in the Klamath Basin. However, the available information is not yet sufficient for making management decisions relative to population independence or uniqueness. Strategies to Address Gaps 1) A Miller Lake Lamprey Technical Management Team has been formed to promote investigation, management and conservation of the Miller Lake Lamprey. This team currently consists of biologists from ODFW ( Roger Smith and Stephanie Gunckel), Oregon State University ( Douglas Markle), the Western Lamprey Project ( Stewart Reid), and the Great Lakes Inst. Environmental Research ( Margaret Docker - lamprey genetics). 2) ODFW will, where appropriate, incorporate lampreys into their fish survey protocols in the Klamath Basin and will seek to collaborate with other researchers carrying out lamprey surveys in the Basin. 3) ODFW and the Miller Lake Lamprey Technical Management Team will promote the investigation of morphological and genetic information informative to resolving regional differences between the various populations of Miller Lake Lamprey. 11 Public Review Draft 4- 27- 05 Research, Monitoring and Evaluation Research Promote scientific studies of the Miller Lake Lamprey to aid in the conservation of the Monitoring Where appropriate, incorporate lampreys into fish survey protocols in the Klamath Basin and seek to collaborate with other researchers carrying out lamprey surveys in the Basin. Evaluation Periodically evaluate the status of Miller Lake lamprey and the success of the conservation plan management strategies. Research - Due to the paucity of available quantitative information on the distribution, life history, habitat requirements of either ammocoetes or adults, ODFW will promote scientific studies of the Miller Lake Lamprey to aid in the conservation of the species. Monitoring - ODFW, in collaboration with USFWS, has documented baseline distribution of the fish in Miller Creek with the lamprey barrier in place ( Gunckel and Reid 2004). Monitoring of the population will continue to evaluate upstream movement, distribution, abundance, and re- colonization of the lake through the cooperative effort of ODFW and the Miller Lake Lamprey Technical Management Team. The ODFW and the Technical Management Team, will meet and discuss progress after the barrier has been removed, and the lampreys have had unobstructed passage to Miller Lake for five years. Adaptive Management a) A Miller Lake Lamprey Technical Management Team shall be formed. b) The Miller Lake Lamprey Technical Management Team shall meet periodically to review the success of the management actions identified in the Miller Lake Lamprey Conservation Plan and identify modifications to management actions that are needed to achieve the desired status for Miller Lake lamprey. No immediate threats to the Miller Lake Lamprey are known to currently exist, except for the barrier in Miller Creek. The Miller Lake Lamprey Technical Management Team ( see under Strategies to Address Gaps) has been formed to promote investigation, management and conservation of the Miller Lake Lamprey. The team will meet periodically to evaluate current status and management strategies in light of new information. 12 Public Review Draft 4- 27- 05 Current management action is proposed for removal of the Miller Creek Barrier. The lamprey population in Miller Creek will continue to be monitored by ODFW following the 2004 baseline surveys. After five years the Miller Lake Lamprey Technical Management Team will evaluate the status of the Miller Creek population and the success of natural re- colonization of Miller Lake. If sufficient progress has not been made, then discussions regarding active re- introduction of lampreys to the lake will be initiated. Trigger for Plan Modification Substantial negative changes in the distribution or abundance of the Miller Lake lamprey, or the recognition of new threats to the species, shall prompt a review of the species management unit's status and all Miller Lake Lamprey Conservation Plan management strategies by the Miller Lake Lamprey Technical Management Team. Appropriate modifications to the Miller Lake Lamprey Conservation Plan intended to better achieve the desired status identified in the Plan shall be proposed by the Miller Lake Lamprey Technical Management Team. Reporting a) The Miller Lake Lamprey Technical Management Team shall periodically report on the status of Miller Lake lamprey and the effectiveness of the management strategies identified in the Miller lake Lamprey Conservation Plan. b) Annual Miller Lake Lamprey data collected and any reports on the status of Miller Lake Lamprey or evaluations of the Miller Lake Lamprey Conservation Plan shall be made available to the public. The staff of the ODFW's Klamath Watershed District and Native Fish Research Project will periodically report monitoring and research results through native fish conservation strategy stock status reviews. 13 Public Review Draft 4- 27- 05 Citations Bond, C.

  	Citation × Citation Citation Abstract Copy Title: Reproductive biology and demographics of endangered Lost River and shortnose suckers in Upper Klamath Lake, Oregon Author: Perkins, David L.; Scoppettone, Gary; Buettner, Mark Year: 2000, 2005 We analyzed the reproductive biology and demographics of the Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris, two endangered species endemic to the upper Klamath Basin of Oregon and California, from 1984-1997. Lost River suckers had distinct river and lake shoreline spawning stocks, and individuals of both species commonly spawned in consecutive years. In the Williamson River and lower Sprague River, spawning migration by both species occurred mainly during a 5-week period that started within the first three weeks of April and peaked between mid April and early May, although a separate, earlier (mid March) run of Lost River suckers may also spawn in the upper Sprague River. Migration of both species was several times higher at dawn (0500-0730 h) and evening (1800-2200 h) than other times of the day. Peak migrations almost always corresponded to peaks in water temperature, usually at 10-15°C. Lost River suckers were captured at springs along the east shore of the lake from late February through mid May, with peak spawning usually in mid March to mid April. Shortnose suckers were generally captured at the springs from late March through late May, but the time of peak spawning was not determined. Size and age at maturity was determined by recruitment from a strong year class (1991). Male Lost River suckers began recruitment into the adult population at age 4+ (375-475 mm). Substantial recruitment of females did not begin until age 7+ (510-560 mm). Male and female shortnose suckers began recruitment at age 4+, with the majority offish recruited by age 5+. Males recruited at 270-370 mm; females recruited at 325-425 mm. Fecundity estimates were quite variable ranging from 44,000-236,000 eggs per female Lost River sucker and 18,000-72,000 eggs per female shortnose sucker. In 1984 and 1985, the spawning populations of both species were dominated by large, old individuals, with little indication of recent adult recruitment. In the next 13 years, only one strong year class (1991) recruited into the spawning populations of both species. This year class temporarily boosted population numbers, but annual fish kills from 1995 to 1997 eliminated most adults of both species. Associated with poor water quality caused by the proliferation and decay of blue-green algae Aphanizomenonflos-aquae, these fish kills raise concern that alterations to the lake ecosystem over the past several decades have Perkins et al. Lost River and shortnose suckers 5 increased the magnitude and frequency of poor water quality. As a result, mortality rates of all life stages may have increased, thereby disrupting the species' life history pattern and potentially decreasing long-term population viability. Introduction The Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris are large, long-lived suckers endemic to the upper Klamath Basin of Oregon and California. Both species are typically lake dwelling but migrate to tributaries or shoreline springs to spawn (Moyle 1976, Scoppettone and Vinyard 1991). Once extremely abundant (Cope 1884, Gilbert 1898), both species have experienced severe population declines and were federally listed as endangered in 1988 (USFWS 1988). Much of the original habitat of these suckers has been destroyed or altered by conversion of lake areas to agriculture, dams, instream flow diversions, and water quality problems associated with timber harvest, loss of riparian vegetation, livestock grazing, and agricultural practices (USFWS 1988). Knowledge of the life history of Lost River and shortnose suckers is fundamental to recovery of these species. The objective of this report was to present the results of studies conducted from 1987-1998 on the reproductive biology and demographics of Lost River and shortnose suckers, and to compare these results with earlier unpublished data. Study Sites Studies were conducted on Upper Klamath Lake and the lower Williamson-Sprague river system (Figure 1). These waters form the upper portion of the Klamath River Basin in south-central Oregon and represent most remaining native habitat of Lost River and shortnose suckers. Upper Klamath Lake is a remnant of pluvial Lake Modoc that included eight major basins and encompassed 2,839 km2 (Dicken 1980). Today, Upper Klamath Lake serves as a storage reservoir that provides water for agricultural irrigation, waterfowl refuges, instream flow requirements of anadromous fish, and hydroelectric power generation. At full capacity, the lake covers approximately 360 km2 and has an average depth of 2.4 m. Most deeper water (3-12 m) is restricted to narrow trenches along the western shore.
