Craig Year: 2001, 2008, 2005 1 Acknowledgements 2 3 The completion of this work in large part can be attributed to the efforts of the 4 U.S. Fish and Wildlife Service Arcata Field Office staff and in particular to Mr. 5 Thomas Shaw for providing much of the supporting site-specific field data, 6 habitat mapping, and fisheries data used in the analyses. The efforts of the 7 various Tribal fisheries personnel were critical in supplying additional fisheries 8 collection data, and intensive site substrate and cover mapping. In particular, the 9 efforts of Tim Hayden, Charlie Chamberlain and Mike Belchik. USGS personnel 10 from the Midcontinent Ecological Science Center also provided valuable 11 assistance and field data used in the cross section based hydraulic and habitat 12 modeling. Mr. Gary Smith and Mike Rode of the California Department of Fish 13 and Game also provided critical information on site-specific habitat suitability 14 criteria and conceptual foundations for the escape cover analysis used in the 15 habitat simulations. Much of this work was also supported by work of Tim 16 Harden (Harden and Associates). The Bureau of Reclamation also provided 17 valuable input during the Phase II study process on Klamath Project operations. 18 A special thanks is also given to Mr. Mike Deas (U.C. Davis) for providing water 19 temperature simulations below Iron Gate Dam. The Technical Team also 20 provided critical input and review of all technical elements of this work as well as 21 providing reviews of the report. Finally, the completion of this work would not 22 have been possible without the tireless efforts of Jennifer Ludlow, Mark 23 Winkelaar, James Shoemaker, Shannon Clemens, Jerilyn Brunson, William 24 Bradford, Sarah Blake, Brandy Blank, Matt Combes, Leon Basdekas, and Aaron 25 Hardy at the Institute for Natural Systems Engineering, Utah State University. 26 27 Executive Summary 28 29 Previous instream flow recommendations developed as part of Phase I (Hardy, 30 1999) recommended interim instream flows in the main stem Klamath River 31 based on analyses of hydrology data. At that time, site-specific data suitable for 32 analysis and evaluation using habitat based modeling were not available. This 33 report details the analytical approach and modeling results from site-specific 34 studies conducted within the main stem Klamath River below Iron Gate Dam 35 downstream to the estuary. Study results are utilized to make revised interim 36 instream flow recommendations necessary to protect the aquatic resources 37 within the main stem Klamath River between Iron Gate and the estuary. This 38 report also makes specific recommendations for future research needs as part of 39 the on-going strategic instream flow studies being undertaken by the U.S. Fish 40 and Wildlife Service and collaborating private, local, state, federal, and tribal 41 entities. 42 43 This report was developed for the Department of the Interior (DOI) who provided 44 access to a technical review team composed of representatives of the U.S. Fish 45 and Wildlife Service, Bureau of Reclamation, Bureau of Indian Affairs, U.S. 46 Geological Survey, and the National Marine Fisheries Service. The technical Draft - Subject to Change 1 review team also included participation by the Yurok, Hoopa Valley, and Karuk 2 Tribes given the Departments trust responsibilities and the California Department 3 of Fish and Game as the state level resource management agency. The 4 technical review team provided invaluable assistance in the review of methods 5 and results used in the analysis, provided comments on draft sections of the 6 report, and provided data and supporting material for use in completion of the 7 Phase II report. In addition, several agencies and private individuals provided 8 written comments on the Preliminary Draft Report, which have been addressed in 9 this report where appropriate. 10 11 This report is organized to follow the general process used to implement the 12 technical studies. It first provides important background information on the 13 historical and current conditions of the anadromous species, highlights factors 14 that have contributed to their decline, provides an overview of the Phase I study 15 process and its principal findings. The report then continues with a description of 16 the Phase II technical study process. Key sections address methods and 17 findings for each technical component such as study design, study site selection, 18 field methods, analytical approaches, summary results, and recommended 19 instream flows. 20 21 The Phase II study relied on state-of-the-art field data collection methodologies 22 and modeling of physical habitat for target species and life stages of anadromous 23 fish. The field methods were directed toward achieving a three-dimensional 24 representation of each study site that incorporated between 0.6 to over one mile 25 of river depending on the specific study site. At each study site, a spatially 26 explicit substrate and vegetation map was developed and then integrated with 27 the three-dimensional channel topography in GIS. Fieldwork also involved 28 collection of hydraulic calibration data and fish observation data. The later 29 information was used in the development of habitat suitability criteria, conceptual 30 habitat model development and implementation, and habitat model validation 31 efforts. 32 33 Hydrology in the main stem Klamath River below Iron Gate Dam was estimated 34 differently for different purposes in Phase II. For example, we used simulated 35 unimpaired inflows (i.e., no depletions) to Upper Klamath Lake routed to Iron 36 Gate Dam with no Klamath Project imposed water demands. This simulated 37 scenario represents the best available estimates of the unimpaired flows below 38 Iron Gate Dam for the purposes of this study. The remaining flow scenarios 39 included the use of Upper Klamath Lake net inflows, historical Klamath Project 40 water demands, and the USFWS Biological Opinion (2000) target Upper Klamath 41 Lake water elevations. These scenarios represent different potential operational 42 flow scenarios as points of reference to the instream flow recommendations 43 developed as part of Phase II. Differences between these simulated flow 44 scenarios required the use of different models and/or modeling assumptions. 45 The assumptions and modeling tools are described in the appropriate technical 46 sections of the report. The estimated hydrology at each study site was used in Draft - Subject to Change 1 both the physical habitat modeling and temperature simulations using the USGS 2 Systems Impact Assessment Model (SIAM) or its components. 3 4 Physical habitat modeling at each study site relied on two-dimensional hydraulic 5 simulations that were coupled to three-dimensional habitat models. The 6 analytical form of the habitat models varied for spawning, fry, and 'juveniles' (i.e., 7 pre-smolts). These modeling results were compared to available 1-dimensional 8 cross section based hydraulic and habitat modeling at study sites that overlapped 9 between existing USFWS/USGS and Phase II studies. 10 11 Habitat suitability criteria for target species and life stages of anadromous fish 12 were developed from site-specific data for Chinook spawning, Chinook fry, and 13 steelhead 1+. These curves were validated both by field observations using the 14 habitat modeling results as well as by comparison to results from an individual 15 based bioenergetics model for drift feeding salmonids developed at USU. A 16 separate procedure was developed to obtain habitat suitability curves for Chinook 17 juvenile (i.e., pre-smolts), steelhead fry, and coho fry based on available 18 literature data. This approach used a systematic process to construct an 19 'envelope' habitat suitability curve that encompassed the available literature 20 curves. The overall process included a validation component that compared the 21 habitat versus discharge relationships between envelope curves to the site- 22 specific curves for Chinook spawning, Chinook fry, and steelhead 1+. The results 23 validated the use of the envelope curves for use as interim criteria pending 24 further research and development of site-specific curves for these species and 25 life stages within the Klamath River. 26 27 Habitat modeling involved the integration of substrate and cover mapping with 28 the three-dimensional topography and hydraulic properties at each study site with 29 the habitat suitability curves. Habitat modeling was undertaken for Chinook 30 spawning, fry, and juveniles, coho fry and juveniles, and steelhead fry and 31 steelhead 1+. Different habitat models were developed for spawning, fry, and 32 juveniles. The study generated a salmonid fry habitat model that incorporated a 33 distance to escape cover that also required sufficient depth within the escape 34 cover in order for it to be utilized at a given flow rate. This model also 35 incorporated quantitative differences in the type of escape cover. 36 37 The habitat modeling results for each species and life stage were validated 38 against the spatial distribution of each species and life stage surveyed at study 39 sites at different flow rates. These results generally demonstrated that the 40 integrated habitat modeling was validated for the study in terms of spawning and 41 fry life stages. Our assessment of the pre-smolt or juvenile life stage results is 42 that they are consistent for the existing habitat model assumptions. However, we 43 discuss what we perceive to be inherent biases in these results (juveniles) based 44 on the existing habitat model structure and make specific recommendations of 45 what additional work would likely improve the results for this particular life stage. 46 Draft - Subject to Change jjj 1 Temperature simulations based on the unimpaired flow regime below Iron Gate 2 Dam were conducted with HEC5Q as part of the SIAM applications. These 3 results supported the findings in Phase I that flows lower than ~ 1000 cfs during 4 the late summer would likely increase the environmental risk to anadromous 5 species due to almost continual exposure to chronic temperature thresholds. We 6 believe that these simulation results show that there is very little flexibility for 7 reservoir operations at Iron Gate Dam to mitigate deleterious flow dependent 8 temperature effects. This finding has previously been reported by the USGS 9 (Bartholow 1995) and Deas (1999). 10 11 The integration of the habitat modeling with the unimpaired hydrology was used 12 to develop habitat reference values for target species and life stages at each 13 study reach on a monthly basis for flow exceedence ranges between 10 and 90 14 percent. The reference habitat value was computed as the percent of maximum 15 habitat associated with the unimpaired flow values for each species and life 16 stage on a monthly basis. This reference habitat value was used as one 'target' 17 condition to guide the selection of monthly flow recommendations at a given 18 exceedence flow level. 19 20 The flow recommendation process also employed a prioritization of species and 21 life stages to be considered within the year and/or within a specific month. The 22 prioritization of life stages was taken from the life history sequence of 23 anadromous species (i.e., spawning, fry, and then juveniles). The initial priority 24 order for species was defined as Chinook, then coho, and finally steelhead. It is 25 stressed that this initial prioritization was used to conceptually simplify the flow 26 recommendation process only, and that all species and life stages were 27 examined as part of the overall analysis. The process then relied on an iterative 28 procedure to select target flows for each month at a given exceedence level. 29 This procedure attempted to pick a target flow that would simultaneously 30 preserve the underlying characteristics of the seasonal unimpaired hydrograph at 31 that exceedence flow, the underlying relationship of the unimpaired hydrograph 32 between all exceedence flow levels, while striving to maximize habitat for the 33 priority species and life stages relative to the unimpaired habitat reference 34 conditions. The corresponding monthly flow rates at each exceedence level 35 were then used to compute the percent of maximum habitat for all other species 36 and life stages in a given month. These values were then compared to their 37 respective unimpaired habitat values to ensure that adequate protection of 38 habitat for non-priority species and life stages remained reasonable. 39 40 The flow recommendations developed in the Iron Gate to Shasta River Reach 41 were 'propagated' downstream to each successive reach by addition of the reach 42 gains as presently defined by the USGS in their MODSIM module of SIAM. It is 43 recognized that these reach gains reflect existing depletions in tributary systems 44 (e.g., Shasta and Scott Rivers) but are the only estimates presently available for 45 use in the simulation models for the system. The flow recommendations for each 46 river reach were then used to compute the percent of maximum habitat on a Draft - Subject to Change 1 monthly basis for each species and life stage. The recommended flow based 2 calculation of percent of maximum habitat for each species and life stage was 3 then compared against the associated unimpaired flow based habitat values. 4 5 Although flow recommendations were developed for the 10 to 90 percent 6 exceedence range (i.e., nine water year types), five water year types were 7 identified representing Critically Dry, Dry, Average, Wet, and Extremely Wet 8 inflow conditions for Upper Klamath Lake. These water year classifications 9 parallel those developed for the Trinity River and were used as operational 10 definitions in the Phase I report. Furthermore, the USBR KPSIM model was 11 modified to use this five-water year type format for simulating operations under 12 different instream flow requirements below Iron Gate Dam. The 90, 70, 50, 30, 13 and 10 percent exceedence flow levels were assigned to each of these water 14 year types, respectively (i.e., critically dry to extremely wet). This assignment 15 was used to demonstrate several key points regarding the use of 16 recommendations at this level of resolution (i.e., five water year types) and how 17 the existing operational models for the Klamath Project simulate flow scenarios. 18 19 These five water year type dependent recommendations were utilized in the U.S. 20 Bureau of Reclamation's Klamath Project Simulation Module (KPSIM) to simulate 21 project operations over the 1961 to 1997 period of record. This analysis 22 confirmed that the project could be operated to achieve these recommendations 23 in all but 19 of the 468 simulated months in this period of record. These results 24 also highlighted that an alternative water year 'classification' strategy for 25 specifying instream flows should be considered in lieu of a five water year type 26 scheme. We provide a specific recommendation of how this could be 27 approached based on the instream flow recommendations developed in Phase II. 28 29 30 Draft - Subject to Change Title: Evaluation of Interim Instream Flow Needs in the Klamath River Phase II Final Report Author: Hardy, Thomas B; Addley.

The remaining flow scenarios 39 included the use of Upper Klamath Lake net inflows, historical Klamath Project 40 water demands, and the USFWS Biological Opinion (2000) target Upper Klamath 41 Lake water elevations. These scenarios represent different potential operational 42 flow scenarios as points of reference to the instream flow recommendations 43 developed as part of Phase II. Differences between these simulated flow 44 scenarios required the use of different models and/or modeling assumptions. 45 The assumptions and modeling tools are described in the appropriate technical 46 sections of the report.

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

  	Citation × Citation Citation Abstract Copy Title: Endangered species consultation handbook : procedures for conducting consultation and conference activities under Section 7 of the Endangered Species Act Author: U.S. Fish and Wildlife Service Year: 1998, 2005 EXECUTIVE SUMMARY Section 7 of the Endangered Species Act (Act) [16 U.S.C. 1531 etseq.] outlines the procedures for Federal interagency cooperation to conserve Federally listed species and designated critical habitats. Proactive Conservation Efforts by Federal Agencies Section 7(a)(l) directs the Secretary (Secretary of the Interior/Secretary of Commerce) to review other programs administered by them and utilize such programs to further the purposes of the Act. It also directs all other Federal agencies to utilize their authorities in furtherance of the purposes of the Act by carrying out programs for the conservation of species listed pursuant to the Act. This section of the Act makes it clear that all Federal agencies should participate in the conservation and recovery of listed threatened and endangered species. Under this provision, Federal agencies often enter into partnerships and Memoranda of Understanding with the Fish and Wildlife Service (FWS) or the National Marine Fisheries Service (NMFS) for implementing and funding conservation agreements, management plans, and recovery plans developed for listed species. Biologists for the Services should encourage the development of these types of partnerships and planning efforts to develop pro-active approaches to listed species management. Avoiding Adverse Effects of Federal Actions Section 7(a)(2) states that each Federal agency shall, in consultation with the Secretary, insure that any action they authorize, fund, or carry out is not likely to jeopardize the continued existence of a listed species or result in the destruction or adverse modification of designated critical habitat. In fulfilling these requirements, each agency must use the best scientific and commercial data available. This section of the Act defines the consultation process, which is further developed in regulations promulgated at 50 CFR ?402. The Handbook This handbook was primarily developed to aid FWS and NMFS biologists implementing the section 7 consultation process. The purpose of the handbook is to provide information and guidance on the various consultation processes outlined in the regulations. Additionally, the handbook will ensure consistent implementation of consultation procedures by those biologists responsible for carrying out section 7 activities. Chapters of the handbook deal with major consultation processes, including Informal, Formal, Emergency, and Special Consultations; and Conferences. Standardized language is provided for incorporation into Biological Opinion documents to achieve consistency and to ensure that all consultation documents are complete from a regulatory standpoint. Background information and example documents are provided in Appendices. Although primarily targeted towards employees of the Services, other groups participating in the consultation process, including other Federal agencies; State, local, and tribal governments; and private individuals, consultants, and industry groups should find the handbook helpful in explaining section 7 processes and providing examples of various types of consultations. This handbook will be updated periodically as new regulations and policies are developed affecting implementation of the section 7 regulations, or as new consultation or assessment techniques evolve, and as additional examples or graphics become available. The Washington Offices of the Services have the lead for preparation of the handbook. Regional offices are encouraged to develop example documents appropriate for their geographical area and individual situations, and to coordinate with other Federal and State agencies in distributing these documents. Consultation Framework Use of Sound Science An overriding factor in carrying out consultations should always be the use of the best available scientific and commercial data to make findings regarding the status of a listed species, the effects of a proposed action on the species or critical habitat, and the determination of jeopardy/no jeopardy to listed species or destruction or adverse modification/no destruction or adverse modification to designated critical habitats. The Services have jointly published a policy on Information Standards Under the Endangered Species Act [59 FR 34271 (July 1, 1994)]. This policy calls for review of all scientific and other information used by the Services to prepare biological opinions, incidental take statements, and biological assessments, to ensure that any information used by the Services to implement the Act is reliable, credible, and represents the best scientific and commercial data available. Flexibility and Innovation The section 7 process achieves greatest flexibility when coordination between all involved agencies and non-Federal representatives, and the Services, begins early. Often, proposed actions can be modified so there is no need for formal consultation. The Services should ensure that all information needed to make an informed decision is made available. It is particularly critical when formal consultation begins that all parties are fully involved in providing information and discussing project options. Although it is the responsibility of the Services to make the determination of jeopardy or destruction/adverse modification in the biological opinion, action agencies and applicants should be fully informed and involved in the development of Reasonable and Prudent Alternatives, Reasonable and Prudent Measures, and Terms and Conditions to minimize the impacts of incidental take. Biologists should be creative in problem solving and look for ways to conserve listed species while still accommodating project goals. Coordination The Services have a policy to ensure coordination with State Agencies for gathering information in implementing the consultation program. [59 FR 34274-34275 (July 1, 1994)] The Services have a joint policy on coordination with tribal governments. Secretarial Order #32306 (June 5, 1997) entitled "American Indian Tribal Rights, Federal-Tribal Trust Responsibilities, and the Endangered Species Act" recognizes that the consultation process should include input from affected tribal governments. State and tribal government biologists often have information available that is pertinent to the description of the action area or to the species of interest in the consultation. Shortening Timeframes Recently, the Services have been implementing measures to streamline consultation processes. Examples include projects reviewed under the Northwest Forest Plan and nationwide Timber Salvage Program. These procedures have been able to effectively shorten consultation timeframes without giving up any protection for listed species/designated critical habitats or the use and review of the best available information. This has been achieved through enhanced interagency coordination, development of guidelines for implementation of a larger program (i.e. timber salvage) which can tier to an individual project (timber sale), and by providing consultation simultaneously with project analysis under the National Environmental Policy Act (NEPA). Biologists for the Services are encouraged to review examples of these streamlined consultations and to look for ways to incorporate streamlining techniques into other consultation procedures.

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

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

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.

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.

G Year: 2001, 2007, 2005 ABSTRACT A water quality study was performed in the mainstem Klamath River from Keno, Oregon to Seiad Valley, California during 1996 through 1998. Four sites within the study area were continuously monitored using multiparameter recorders. Water quality sampling was also performed at these four locations in 1996 and 1997. Additional water quality sampling sites were added in 1998 for a total of 8 locations between Keno and Seiad. Temperature ranged from near zero ?C to >25 ?C with cooler temperatures in early spring and fall, and maximum temperatures occurring in July and August of each year. Dissolved oxygen concentration ranged from near zero mg/L to >13 mg/L with highest DO occurring in early spring and fall and lowest DO occurring in mid-summer. Air temperature was generally highly correlated with water temperature with r values ranging from 0.8 to 0.9 during the study period from 1996-1998. Water temperature in the study area exceeded chronic (>16?C) and acute (>22?C) criteria for salmonids during the summer months. Although chronic DO (<7 mg/L) criteria were exceeded throughout most of the study area during the summer, in the free-flowing river below Iron Gate Dam the acute DO (<5.5 mg/L) criteria were not exceeded. Nonpoint source pollution in the form of agricultural return flows, industrial, or sewage effluent entering the stream may have resulted in higher ammonia and total organic nitrogen concentrations at the upstream locations in the Klamath River study area (Keno and J.C. Boyle Powerplant). Nitrification of ammonia and organic nitrogen seemed to result in higher concentrations of nitrate in the downstream Klamath River (Iron Gate Dam). Total phosphorus concentration stayed relatively stable through the reservoirs in the study area, but decreased in the downstream direction between Iron Gate Dam and Seiad. Ortho-phosphorus concentrations increased longitudinally through the reservoirs, then decreased in the downstream direction between Iron Gate Dam and Seiad. An increase in ortho-phosphorus concentration can indicate internal cycling occurring in the reservoirs as well as photosynthesis. On an annual basis total phosphorus loading increased longitudinally from up- to downstream between Keno and Seiad. The increase was statistically significant (p = .03) indicating that the reservoirs in series in the Klamath River study area do not function as a nutrient sink. However, during the summer there was no statistically significant difference in total P loading when Keno, Iron Gate and Seiad locations were compared, therefore, the reservoirs may act as a nutrient sink seasonally. The Klamath River study locations were generally nitrogen limited, although at Keno, a regular change from N limitation to P limitation occurred during the fall of all three years of the study. When the Klamath River annual nutrient loading values are compared to other rivers in the vicinity, the Carson, Truckee, and Long Tom Rivers also appear to be nutrient enriched. The Carson and South Yamhill Rivers seem to be N limited systems and the Wood, Long Tom, Snake and Truckee Rivers seem to be P limited systems. Implementing management strategies for reservoir operations to improve water quality and reduce nutrient concentration or loading in the Klamath River study area to benefit anadromous fisheries may be difficult and expensive. However, improving the thermal regime in spring to benefit YOY salmonids may be possible as is short-term relief in fate summer for over-summering species. Decreases in nutrient concentration or loading accomplished through best management practices in the water shed may allow general protection of water resources in the Klamath Basin for future needs.

  	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.

The purpose of this report is to identify and analyze the potential economic impacts associated with the designation of critical habitat for the Columbia River and Klamath River Distinct Population Segments ( DPSs) of bull trout ( Salvelinus confluentus), hereafter " bull trout." This report was prepared by Bioeconomics, Inc. of Missoula, Montana, for the U. S. Fish and Wildlife Service's ( the Service) Division of Economics. 2. Section 4( b)( 2) of the Endangered Species Act ( the Act) requires the Service to designate critical habitat on the basis of the best scientific data available, after taking into consideration the economic impact, and any other relevant impact, of specifying any particular area as critical habitat. The Service may exclude areas from critical habitat designation when the benefits of exclusion outweigh the benefits of including the areas within critical habitat, provided the exclusion will not result in extinction of the species. KEY FINDINGS Total costs associated with both listing and critical habitat designation for the bull trout are forecast to be $ 200 million to $ 260 million over the next ten years. Total costs associated with both listing and critical habitat designation for the bull trout within the proposed Klamath Distinct Population Segment are forecast to be $ 5.3 million to $ 7.3 million over the next ten years. Total costs associated with both listing and critical habitat designation for the bull trout within the proposed Columbia Distinct Population Segment are forecast to be $ 195 million to $ 253 million over the next ten years. Federal agencies are expected to bear 70 to 75 percent of these costs; private entities will incur the remaining 25 to 30 percent. Project modification costs account for as much as 63 percent of forecast costs. Administrative cost represent the remaining 37 percent. U. S. Forest Service and Army Corps of Engineer- related activities account for approximately 70 percent of forecast project modification costs. Activities experiencing the greatest costs include timber harvesting, irrigation diversions, and dam and reservoir operations. Dam and reservoir- related consultations, including power facility re- licensing, account for 42 percent of forecast project modification costs ( excluding the cost associated with reduced irrigation diversions). Timber harvest, irrigation diversions, habitat conservation plans, and mining account for 29 percent, 12 percent, eight percent, and three percent of forecast costs, respectively. In terms of river miles, approximately 18 percent of the total forecast costs are associated with one percent of the proposed designation, 25 percent with five percent of the proposed designation, and 45 percent with ten percent of the proposed designation. When expressed in terms of the expected cost per river mile, the two most costly units are the Willamette River Basin ( Unit 4) and the Malheur River Basin ( Unit 13). ES- 1 Framework for the Analysis 3. The primary purpose of this analysis is to estimate the economic impact associated with the designation of critical habitat for the bull trout. This information is intended to assist the Secretary in making decisions about whether the benefits of excluding particular areas from the designation outweigh the benefits of including those areas in the designation. 1 This economic analysis considers the economic efficiency effects that may result from the designation, including habitat protections that may be co- extensive with the listing of the species. It also addresses distribution of impacts, including an assessment of the potential effects on small entities and the energy industry. This information can be used by decision- makers to assess whether the effects of the designation might unduly burden a particular group or economic sector. 4. This analysis focuses on the direct and indirect costs of the rule. However, economic impacts to land use activities can exist in the absence of critical habitat. These impacts may result from, for example, local zoning laws, State and natural resource laws, and enforceable management plans and best management practices ( BMPs) applied by other State and Federal agencies. For example, as discussed in detail in this report, regional management plans, such as the Northwest Forest Plan, PACFISH and INFISH provide significant protection to bull trout and its habitat while imposing significant costs within the region. Economic impacts that result from these types of protections are not included in this assessment as they are considered to be part of the regulatory and policy " baseline." 5. The measurement of direct compliance costs focuses on the implementation of section 7 of the Act. This section requires Federal agencies to consult with the Service to ensure that any action authorized, funded, or carried out will not likely jeopardize the continued existence of any endangered or threatened species or result in the destruction or adverse modification of critical habitat. The administrative costs of these consultations, along with the costs of project modifications resulting from these consultations, represent the direct compliance costs of designating critical habitat. Importantly, this analysis does not differentiate between consultations that result from the listing of the species ( i. e., the jeopardy standard) and consultations that result from the presence of critical habitat ( i. e., the adverse modification standard). 6. The analysis examines activities taking place both within and adjacent to the proposed designation. It estimates impacts based on activities that are " reasonably foreseeable," including, but not limited to, activities that are currently authorized, permitted, or funded, or for which proposed plans are currently available to the public. Accordingly, the analysis bases estimates on activities that are likely to occur within a ten- year time frame, beginning on the day that the current proposed rule became available to the public ( November 30, 2002). The ten- year time frame was chosen for the analysis because, as the time horizon for an economic analysis is expanded, the assumptions on which the projected number of projects and cost impacts associated with those projects becomes increasingly 1 16U. S. C. § 1533( b)( 2). ES- 2 speculative. An exception to the 10 year analysis time horizon used in this analysis is for Federal Energy Regulatory Commission ( FERC) licenses, which are renewed for up to 50 years. Accordingly, this analysis estimates the annualized costs of the expected impacts associated with section 7 bull trout consultations involving FERC re- licensing over a 50 year time horizon. 7. The analysis is based on a wide range of information sources. Numerous individuals were contacted from the Service, as well as from the U. S. Forest Service ( USFS), Federal Highway Administration ( FHWA), Bureau of Land Management ( BLM), Army Corps of Engineers ( ACOE), Bureau of Reclamation ( BOR), Bonneville Power Administration ( BPA), Natural Resources Conservation Service ( NRCS), U. S. Environmental Protection Agency ( EPA), National Oceanic and Atmospheric Administration ( NOAA) and other Federal agencies. The analysis of the hydroelectric facilities and other dam structures in the region also relied in information from the Northwest Power and Conservation Council ( NWPCC), the Pacific Northwest Utility Coordinating Council as well as information from utilities owning dams in bull trout proposed critical habitat ( e. g., Avista Corporation ( Avista), Eugene Water and Electric Board, Pacificorp and Portland General Electric ( PGE)). Native American Tribes ( e. g., Confederated Salish and Kootenai Tribes), State agencies ( e. g., State Departments of Environmental Quality ( DEQ) and State Departments of Transportation ( DOTs)) and industry organizations ( e. g., American Forest Resource Council, American Farm Bureau and Northwest Mining Association) were also contacted, as were numerous individuals in the private sector on topics ranging from irrigation to forestry to bull trout conservation. Census Bureau and other Department of Commerce data was relied on to characterize the regional economy. 8. The bull trout was listed as a threatened species in 1998.2 Since that time, numerous Action agencies have participated in well over 200 formal consultations and thousands of informal consultations involving bull trout. The past consultation record was used as a starting point from which to predict future consultation activity. Action agencies provided additional information on likely changes in future consultation activity following designation of critical habitat. In some cases these agencies saw little change in future consultation levels. For example, FHWA projects are planned for many years in advance and bridge or road- related bull trout consultations are generally quite certain and foreseeable. In some cases ( e. g., mining activity, irrigation diversions) it was determined that the historical consultation record understated the potential level of future consultation activity for the species and adjustments to future predicted consultation levels were made. For dam and reservoir operations, a wide spectrum of information from agency representatives, as well as the actual FERC re- licensing schedules for privately operated hydropower facilities were used to augment historical consultation rates and develop future annual cost estimates associated with bull trout consultations on dam, reservoir and power- related activities. 2 This economic analysis applies only to the Columbia River and Klamath River DPSs of bull trout and is not a rangewide analysis. The rangewide listing of the bull trout occurred in 1999 and critical habitat will be proposed for the remainder of the range at a later date. ES- 3 Exhibit ES. l provides a summary of the wide range of activities that may be impacted by bull trout- related consultations.

The economic impacts associated with the designation of critical habitat for the bull trout are expected to range from $ 200 million to $ 260 million over the next ten years ($ 20 million to $ 26 million per year). Federal agencies are expected to bear approximately 70 to 75 percent of the total costs of this designation. A significant portion of the land adjacent to the proposed designation is Federally owned ( 58 percent), 36 percent is under private ownership and the remainder is comprised of Tribal, State or local interests. Of the Federal lands, the majority is managed by the USFS ( 85 percent) and the BLM ( 12 percent). The remaining 25 to 30 percent of costs are expected to be borne by private entities. Exhibit ES. 2 shows the location of USFS and BLM managed land within the proposed designation. ES- 4 Exhibit ES. 2 ES- 5 10. In some cases, the cost associated with consultation is not borne by the Action agency, but passed onto other parties. For example, while farmers and ranchers do not consult on the operation of Federal irrigation impoundments, irrigators could be impacted by potential reductions in water deliveries to maintain instream flow during dry years. While the unit location of USFS- related water diversions is uncertain, it is likely to occur in the Salmon River ( Unit 16), Clark Fork ( Unit 2), Southwest Idaho River and Clearwater River ( Unit 15) Basins, as these units contain the largest portion of USFS managed lands. 11. Consultations that may involve private entities include those related to timber harvest, grazing, mining and power facility re- licensing. Some of the costs associated with these consultations, however, are expected to be borne directly by or passed onto the Federal government ( e. g., increased logging and yarding costs passed onto the USFS through lower stumpage bids for timber). Most of the forecast project modification costs resulting from designation ( 42 percent) are dam and reservoir related ( excluding USFS water diversions). These costs result from consultations on ACOE and BOR dams and reservoirs, BPA consultations on the FCRPS, and FERC re- licensing consultations. Exhibit ES. 3 illustrates the location of major dams within the proposed critical habitat. The remaining project modification costs are associated with timber harvest ( 29 percent), USFS- related water diversions ( 12 percent), habitat conservation plans ( eight percent), and placer gold mining ( three percent). Grazing, forest management, road and bridge construction and maintenance and other activities each account for less than two percent of forecast project modification costs. Exhibit ES. 4 provides the distribution of total costs by activity. 12. Costs can be expressed in terms of unit or river mile; both of these metrics are useful in describing economic impacts. 3 On a cost per unit basis the largest portion of forecast costs are expected to occur in Unit 4, the Willamette River Basin ( 18 percent). These costs are attributable to fish passage and temperature control projects and annual operating and maintenance and fish study costs at ACOE's facilities in the Upper Willamette River System ( Dexter, Lookout Point, Hills Creek and Blue River Dams). The next most costly unit is Unit 16, the Salmon River Basin ( 12 percent). Because this is the largest unit in terms of river miles and proportion of USFS managed land, and because future USFS activities are expected to generate approximately 70 percent of the consultation activity, this unit bears the greatest number of future bull trout- related consultations. Therefore, the administrative costs account for a large portion of the costs in this unit. Together, these two units account for 30 percent ( approximately $ 8.2 million) of forecast costs. The next three most costly units, Hells Canyon complex ( Unit 12) and the Clark Fork River ( Unit 2) and Malheur River ( Unit 13) Basins, each account for eight percent ( a unit cost range of approximately $ 2.1 million to $ 2.3 million) of forecast costs. In total, these five units account for almost 55 percent of forecast costs ( approximately $ 14.8 million). 3 Twelve of the units also contain more than 500,000 lake acres of critical habitat. These units account for approximately 55 percent of the potential economic impacts associated with the proposed designation ($ 15.4 million). The Clark Fork River Basin ( Unit 2) contains almost 60 percent of the lake acres ( more than 300,000 acres) and accounts for eight percent of the cost ( approximately $ 3 million). Because all 25 units contain river miles, the costs are expressed in terms of dollars per river mile for comparison. ES- 6 ES- 7 ES- 8 13. Project modifications or other restrictions that engender cost and revenue impacts involving commercial enterprises can have a subsequent detrimental effect on other sectors of the local economy, especially when the affected industry is central to the local economy. Industries within a geographic area are interdependent in the sense that they purchase output from other industries and sectors, while also supplying inputs to other businesses. Therefore, direct economic effects on a particular enterprise can affect regional output and employment in multiple industries. The extent to which regional economic impacts are realized depends largely on whether a significant number of projects are stopped or fundamentally altered. For example, impacts to the timber or grazing industries depend on whether required project modifications substantially reduce output within economic sectors below that which would be seen in the absence of the trout consultation. 14. Examination of BOs involving timber harvest and grazing show only small and sporadic reductions in either grazing opportunity or available timber harvest. Therefore, this analysis assumes that regional economic impacts associated with these activities will be unpredictable ( in terms of geographic location and timing) and small in the context of the overall economy of the Columbia River Basin. In the case of agricultural water diversions on Forest Service lands, regional economic impacts are not modeled due to uncertainty about the magnitude and potential location of impacts. 15. Exhibit ES- 5 highlights the relative contributions of each unit to total forecast costs. Exhibit ES- 6 then presents the unit cost by river mile. Considering the cost per river mile, the Willamette River ( Unit 4) and Malheur River ( Unit 13) Basins are the most costly units. Together these two units account for 25 percent of the costs ( approximately $ 7.0 million, annualized) over two percent of the proposed miles of the designation ( 451 miles). Overall, 10 percent of the river miles ( 1,910 miles) in eight units account for approximately 45 percent of the total costs ( approximately $ 12.5 million, annualized). 4 4 In terms of cost per lake acre, the Willamette River Basin is the most expensive unit ( Unit 4), followed by the Northeast Washington River ( Unit 22) and Upper Columbia River ( Unit 21) Basins. These three units account for approximately 25 percent of the cost ($ 6.8 million) and five percent of the river miles ( 1,020 miles) in the proposed designation. ES- 9 tn m W GO 16. Consideration of the regulatory baseline is particularly pertinent in the context of estimating economic costs attributable to section 7 for bull trout. Specifically, existing regulations such as the Federal Power Act ( FPA) and Wilderness Act of 1964, fisheries management directives ( Northwest Forest Plan, INFISH and PACFISH) and the presence of other listed species ( especially anadromous fish) provide for the protection of areas that could contribute to the recovery of bull trout and improve riparian habitat and water quality throughout the proposed designation. Thus, the costs of this designation is limited by the extent to which existing regulations already impose requirements on land use and resource management within the proposed designation. In addition, the cost estimates developed in this report reflect various allocations made throughout the analysis for projects benefitting more than one listed species. Since these allocations are important to the analysis, Exhibit ES. 7 describes how forecasted costs were allocated among bull trout and other listed species. Exhibit ES. 7 ALLOCATION OF ESTIMATED FUTURE PROJECT MODIFICATION COSTS Agency / Project ACOE - Upper Willamette River Dams and Reservoirs BPA - Federal Columbia River Power System FERC - re- licensing hydroelectric facilities USFS activities Allocation NOAA Fisheries and the Service are currently consulting on salmon, steelhead and bull trout in this proposed area. No clear allocation of costs can be made between these species, as most of the projects modifications would be sought under both the NOAA and Service consultations. Therefore, one- third of estimated costs are allocated to each species. This is likely to overstate the cost of bull trout conservation rather than understate it, since the primary driving force behind these project modifications is the salmon. While there is extensive discussion of the relative magnitude of potential bull trout versus salmon mitigation actions, because of the relatively modest project modification costs ( up to $ 400,000 associated with fishery studies) there is no allocation of costs to salmon. The estimation of section 7 bull trout costs associated with FERC re- licensing includes allocation of mitigation costs for specific dams to salmon, as well as to other aquatic species. As a result, a little more than 40 percent of total fishery-related costs are allocated to bull trout, and five percent specifically to bull trout section 7 consultation. While certain costs in the sample of timber consultations were allocated to other listed species ( e. g. grizzlies and cutthroat trout), there is no allocation of costs to anadromous species. Summary of Costs 17. Exhibit ES. 8 provides a detailed summary of the co- extensive costs of designation of critical habitat for the bull trout. These costs are presented on an annualized basis. A map of the watersheds that encompass each unit is provided in Exhibit ES. 9 to assist the reader in understanding the location and distribution of estimated costs.

Costs are reported in 2003 dollars. A more detailed presentation of these costs is provided in Appendix F. a Miscellaneous costs ($ 213,000 annually) and the costs associated with development of habitat conservation Dlans ($ 1,090,000 annuallv) have not been allocated to the unit level due to uncertainty as to their location. ES- 13 Exhibit ES- 9 ES- 14 Unit- bv- Unit Summary 18. The following discussion presents a unit- by- unit synopsis of the co- extensive costs of designation of critical habitat for the bull trout. Details on how these cost estimates were developed is provided in Section 4 of this report. 19. From an aggregate perspective, forecast project modification costs are dominated by dam related activities, totaling about 42 percent of all estimated costs. Typical costs include fish passage, changes in operations, habitat protection or restoration, and fishery studies at 36 FERC- licensed hydroelectric facilities and at more than 30 major Federal hydropower, irrigation and flood projects. The second largest category of costs is associated with timber harvest on Federal lands, representing about 29 percent of all estimated costs. These costs include harvest reduction, fishery study and monitoring costs, costs related to roads and culverts, and changes to log yarding systems. The remaining costs are split among a large number of activities including the development of habitat conservation plans, mining, agriculture and irrigation diversions, grazing, bridge construction and maintenance, and general forest management. Accordingly, the primary factor driving the distribution of costs across units is the location of significant dam projects for power, irrigation, and flood control. This factor is highlighted in the following unit- by- unit discussion. The second most important factor is the occurrence of federally- owned acreage within a given unit, particularly the acreage of non- wilderness lands managed by the USFS. This factor drives both timber costs and administrative consultation costs. 20. A significant component of the total estimated cost of this designation are the administrative costs associated with conducting both formal and informal consultations on the species ( approximately 37 to 50 percent of total forecast bull trout- related costs). These costs accrue to the Service as well as to action agencies and the public. In some cases these administrative costs constitute a majority of the estimated costs for a unit, suggesting that there will be many activities consulted on but few resulting project modifications. 21. This discussion is presented on a unit by unit basis. A perspective on how the units compare, in both absolute terms and in terms of cost per river mile of proposed critical habitat, is provided in Exhibits ES- 6 and ES- 7. For purposes of this summary, proposed units with per mile costs ( after adjusting each unit's costs for its respective unoccupied habitat) forecast to be less than half of the proposed designation- wide average are described as having " relatively low costs." Units with per mile costs forecast to be between 50 percent and 200 percent ( i. e., twice) the designation- wide average costs are described as having " relatively moderate costs." Units with per- mile costs forecast to be greater than twice the designation- wide average costs are described as having " relatively high costs." Note that these descriptors are intended as a general guide, and refer to total cost only. Individual economic sectors and entities within a unit may bear disproportionate shares of these costs, as discussed in Section 4. 22. Unit 1: Klamath River Basin - The Klamath River Basin is located in south- central Oregon. Proposed critical habitat within this unit includes 475 km ( 295 mi) of streams and ES- 15 3,775 ha ( 9,327 ac) of lake habitat. The Klamath River Basin Unit is largely contained within Klamath County Oregon. The town of Klamath Falls is the largest community within the county. The Klamath River Basin Unit has a relatively high percentage of proposed critical habitat that is currently either unoccupied or of unknown occupancy ( 72 percent). Approximately 69 percent of the stream miles proposed for designation are within Federal land. 23. The Klamath River Basin Unit is a relatively moderate cost unit. Estimated total annual bull trout- related costs within this unit range between $ 529,000 and $ 733,000. These estimates include $ 425,000 per year in administrative costs. It is estimated that costs associated with consultations on timber harvest and agricultural irrigation withdrawals will constitute the large majority of potential future project modification costs in the unit ( estimated at between 73 percent and 87 percent of total annual project modification costs). These agricultural diversion- related costs are expected to result from reductions in available irrigation water. Other activities are individually estimated to each account for less than $ 15,000 dollars per year in project modification costs. 24. Unit 2: Clark Fork River Basin - The Clark Fork River Basin Unit is the largest unit within the proposed designation. This unit includes most of Western Montana and the Idaho panhandle. This Unit includes the Missoula and Bitterroot River Valleys in Western Montana, the Kalispell- Flathead Lake Region, and the Lake Pend Orielle Region of North Idaho. These areas contain many of the larger towns and communities within Western Montana and North Idaho. Approximately 54 percent of the proposed streams and 33 percent of proposed lakes in Clark Fork Unit are within Federal lands. There is no unoccupied habitat within the proposed Clark Fork Critical Habitat Unit. 25. Forecast total annual costs associated with the bull trout within this unit are between $ 1.3 million and $ 2.2 million. These estimates include $ 800,000 per year in administrative costs. In addition, a number of agencies and activities will incur significant annual project modification costs associated with the bull trout in this unit. Specifically, • Timber harvest activity is expected to generate the largest share of future project modification costs in this unit ($ 270,000 to $ 680,000 per year). These costs include harvest reduction, fishery study and monitoring costs, costs related to road and culverts, and changes to log yarding systems. • Costs associated with forecast project modifications to irrigation diversions within this unit range from zero to $ 280,000. These costs represent potential costs to agricultural producers associated with reductions in available irrigation water. 26. Other significant forecast project modification costs within this unit are associated with mining ( up to $ 100,000 annually, principally involving watershed assessment costs), FERC hydro re- licensing ($ 50,000 to $ 91,000 annually), and FHWA bridge and road work ($ 45,000 per year, generally involving constraints on in- stream work periods). Forecast FERC- related costs are associated with several major hydroelectric facilities within the unit, ES- 16 including Kerr Dam on the Flathead River and Thompson Falls Dam on the Clark Fork. Additionally, bull trout- related modifications on operation of the FCRPS have resulted in changes in operations at Hungry Horse Dam ( a BOR facility on the S. Fork of the Flathead) and Albeni Falls ( an ACOE facility that controls the level of Lake Pend Orielle). Bull trout study costs specific to the Clark Fork Unit and associated with FCRPS consultation are expected to cost up to $ 97,000 annually. 27. Although the proposed Clark Fork River Basin Critical Habitat Unit has significant forecast total annual costs, these costs should be viewed in light of the large size of this proposed unit. In fact, the Clark Fork Unit is forecast to be one of the lowest cost units, when expressed per river mile of habitat proposed for designation. 28. Unit 3: Kootenai River Basin - A short stretch of the Kootenai River lies in the U. S., looping down out of British Columbia. The Kootenai Unit thus comprises only the northwestern corner of Montana, including Libby Dam, and the northeastern tip of the Idaho panhandle. This unit is contained within two counties, Boundary County, Idaho and Lincoln County, Montana. Within this proposed critical habitat unit, approximately 53 percent of the rivers and streams proposed for designation are on Federal land. There is no unoccupied bull trout habitat within this unit. 29. The Kootenai River Unit is a relatively low- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Total forecast annual costs associated with the bull trout within this unit are between $ 328,000 and $ 402,000. Of this amount, the majority, approximately $ 290,000 annually, are forecast administrative costs. In addition, it is estimated that project modification costs within the Kootenai River Unit will total between $ 38,000 and $ 112,000 annually. Costs associated with timber harvest are expected to be the largest category of future project modification costs in this unit ($ 27,000 to $ 69,000 per year, including costs of harvest reduction, fishery study and monitoring costs, costs related to roads and culverts, and changes to log yarding systems). Costs resulting from modifications to agricultural irrigation diversions ( primarily reductions in irrigation withdrawals) could range from zero to $ 28,000. Other activities are individually estimated to each account for less than $ 5,000 per year in project modification costs. Bull trout- related modifications to operations of the FCRPS have resulted in changes in operations at Libby Dam. 30. Unit 4: Willamette River Basin - The Willamette River Basin Unit includes 337 km ( 209 mi) of stream and 1,600 ha ( 3,954 ac) of lake habitat in the McKenzie River and Middle Fork Willamette River subbasins of Western Oregon. The unit is located primarily within Lane County, but also extends into Linn County. The unit contains Eugene, Oregon and surrounding areas. Approximately 46 percent of the proposed waters within this unit are on Federal land and about 23 percent of the waters in the unit are currently either unoccupied by the bull trout or of unknown occupancy. 31. Forecast total annual costs associated with the bull trout within this unit are between $ 4.5 million and $ 4.9 million. Of this amount, approximately $ 125,000 are forecast ES- 17 administrative costs. Thus, most of the costs for this unit are associated with required project modifications. While project modification costs are forecast to be associated with timber harvest activities and agricultural diversions within this unit ( estimated between $ 22,000 and $ 55,000 annually), the vast majority of forecast costs are associated with dam and reservoir operations in the unit. 32. The ACOE is currently in consultation on 13 flood control facilities located in the Upper Willamette River system. Potential future costs of required modifications for bull trout will likely be driven by provisions for temperature control facilities at the Lookout Point, Hills Creek, and Blue River dams, and trap and haul passage at Lookout Point, Hills Creek, and possibly a fish ladder at Dexter Dam. It is estimated that these passage and temperature control modifications and operation at ACOE operated impoundments in the unit will cost between $ 4.3 and $ 4.5 million per year. It is further estimated that annual project modification costs associated with FERC re- licensing of hydroelectric facilities in the unit will cost between $ 70,000 and $ 144,000 annually. These costs are associated with several hydroelectric facilities operated by the City of Eugene: Trail Bridge and Carmen on the McKenzie River, and Blue River Dam. 33. The Willamette River Unit is the highest cost of the proposed units in terms of forecast cost per river mile of habitat proposed for designation ( greater than $ 20,000 per river mile, annually). These costs are associated with dam and reservoir modifications to ACOE projects. However, the ACOE is also consulting with NOAA Fisheries on the impacts of these facilities on chinook salmon and steelhead, these costs might occur even absent the bull trout. 34. Unit 5: Hood River Basin - The Hood River Unit lies entirely within Hood River County, Oregon and contains the communities of Hood River and The Dalles among a number of smaller towns. The Unit includes the mainstem Hood River and three major tributaries: the Clear Branch Hood River, West Fork Hood River, and East Fork Hood River. A relatively high 43 percent of the proposed habitat in the Hood River Unit is currently either unoccupied or of unknown occupancy. Overall, about 48 percent of the waters proposed for designation within this unit are located on Federal lands. 35. The Hood River Unit is a relatively moderate- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit are between $ 328,000 and $ 413,000. Of this amount, a substantial portion are forecast administrative costs ( approximately $ 282,000). The remainder of the forecast costs are associated with required project modifications. Costs associated with FERC re- licensing of hydroelectric facilities ($ 24,000 to $ 67,000) and timber harvest on USFS lands ($ 16,000 to $ 40,000 per year) are expected to be the most significant categories of future project modification costs in the unit. FERC licensed facilities include Powerdale on the Hood River. Agricultural irrigation diversions in the unit could experience up to $ 16,000 in annual project modification costs. Other activities are individually estimated to account for less than $ 5,000 per year in project modification costs. ES- 18 36. Unit 6: Deschutes River Basin - The Deschutes River Basin Unit in central Oregon contains two critical habitat subunits: the lower Deschutes and the upper Deschutes, separated by Big Falls, an impassible barrier on the Deschutes River. The Lower Deschutes critical habitat subunit is in Wasco, Sherman, Jefferson, Deschutes, and Crook Counties. The Upper Deschutes River critical habitat subunit is located in Deschutes, Crook, and Klamath counties. Approximately 801 km ( 498 mi) of stream habitat in the Deschutes River basin is proposed for critical habitat designation. Overall, a relatively high 37 percent of the proposed habitat within the Deschutes River Unit is unoccupied. The entire upper Deschutes River Critical Habitat subunit is currently unoccupied by the species. A relatively low portion ( 35 percent) of the waters proposed for designation within this unit are on Federal land. This unit also has a substantial amount of Tribal land ( 23 percent of proposed waters). 37. The Deschutes River Unit is a relatively low- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. It is forecast that total annual costs associated with the bull trout within this unit will be between $ 431,000 and $ 719,000. A relatively small portion of this amount, approximately $ 102,000 annually, are forecast administrative costs. The vast majority of these costs are associated with required project modifications. Specifically, costs associated with operation of BOR irrigation impoundments ($ 159,000 annually, largely associated with fishery studies), FERC re- licensing of hydroelectric facilities, ($ 106,000 to $ 280,000) and timber harvest on USFS lands ($ 42,000 to $ 105,000 per year resulting from reduced harvest, fishery studies, road and culvert costs, and changes in yarding systems) are expected to be the most significant categories of future project modification costs in this unit. The BOR- related costs are for studies at Crane Prairie and Wickiup Reservoirs on the Upper Deschutes River. Since both of these reservoirs are in the currently unoccupied Upper Deschutes subunit, dam and reservoir modifications are not reasonably foreseeable. Projected FERC re- licensing costs are for bull trout studies and passage at the Pelton- Round Butte Project on the Deschutes River. Agricultural irrigation diversion project modification costs associated with potential reductions in irrigation water availability could range from zero to $ 43,000 annually. Other activities are individually estimated to account for less than $ 15,000 dollars per year in project modification costs. 38. Unit 7: Odell Lake - The Odell Lake Unit in central Oregon lies entirely within the Deschutes National Forest in Deschutes and Klamath counties. This unit is the smallest of the proposed units within the designation. Total proposed critical habitat includes approximately 2,675 ha ( 6,611 ac) of lake habitat and 18.1 km ( 11.3 mi) of streams. There is no unoccupied habitat within this unit. 39. Total annual costs associated with the bull trout within the unit are forecast to be between $ 51,000 and $ 56,000. Of this amount, almost all ( approximately $ 50,000 annually) will be associated with the administrative costs of the consultation process. It is estimated that project modification costs within the Odell Lake Unit will total less than $ 5,000 annually. These project modification costs are forecast to be largely associated with USFS activities. ES- 19 40. Unit 8: John Day River Basin - The John Day River Basin Unit in eastern Oregon includes the North Fork, the Middle Fork, and mainstem portions of the John Day River and their tributary streams in Wheeler, Grant, and Umatilla counties. A total of 1,080 km ( 671 mi) of stream habitat is proposed for designation as critical habitat. Overall, 19 percent of the proposed areas within the John Day River Unit are currently unoccupied by the species. Approximately 54 percent of the waters proposed for designation within the John Day Unit are located on Federal land. 41. The John Day River Unit is a relatively low cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Total annual costs associated with the bull trout within this unit are forecast to be between $ 446,000 and $ 600,000. Of this amount, a large portion, approximately $ 278,000 annually, will be made up of administrative costs. The remainder of the forecast costs are associated with required project modifications. Specifically, project modifications associated with timber harvest on USFS lands ($ 57,000 to $ 143,000 per year from reductions in harvest, fisheries studies, road and culvert costs, and changes in yarding systems) and placer mining on USFS lands ( up to $ 88,000 per year associated with requirements for and limitations on allowed stream crossing activity) are expected to generate the greatest share of project modification costs in this unit. Costs associated with agricultural irrigation diversion reductions could range from zero to $ 58,000 annually. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. The John Day River Basin is one of two units identified in this study as a setting where bull trout related project modifications could have a significant impact on a small placer mining business, the other is the Hells Canyon Complex ( Unit 12). 42. Unit 9: Umatilla- Walla Walla River Basins - The Umatilla and Walla Walla Rivers Unit is located in northeastern Oregon and southeastern Washington. The unit includes 636 km ( 395 mi) of streams extending across portions of Umatilla, Union, and Wallowa counties in Oregon, and Walla Walla and Columbia counties in Washington. Overall, 17 percent of the proposed critical habitat within this unit is currently unoccupied by the species. A relatively low portion ( 32 percent) of the waters proposed for designation within the Umatilla- Walla Walla Unit are located on Federal land. 43. The Umatilla- Walla Walla River Unit is among the lowest cost units, in terms of consultation- related cost per river mile of habitat proposed for designation. It is estimated that total annual costs associated with the bull trout within this unit will be between $ 98,000 and $ 211,000. Of this amount, approximately $ 59,000 annually will be associated with the administrative costs of the consultation process and the remainder with required project modifications. Specifically, fisheries studies associated with FCRPS consultations could cost up to $ 43,000 annually. Project modification associated with timber harvest on USFS lands is expected to be another significant category of future costs in this unit ($ 26,000 to $ 65,000 per year). Agricultural irrigation diversions could experience up to $ 26,000 in annual project modification costs within this unit. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. In addition to the consultation and project modification costs, the Walla Walla Drainage is in ES- 20 the final stages of developing a basin- wide habitat conservation plan to protect bull trout, among other species. The plan has cost approximately $ 4 million to develop, and it is expected an additional $ 1 million will be spent to complete the plan during the next year or two. 44. Unit 10: Grande Ronde River Basin - The Grande Ronde Unit extends across Union, Wallowa, and Umatilla counties in northeastern Oregon, and Asotin, Columbia, and Garfield counties in southeastern Washington. This unit includes the Grande Ronde River from its headwaters to the confluence with the Snake River and a number of its tributaries, the largest being the Wallowa River. Approximately 1,030 km ( 640 mi) of stream habitat in the Grande Ronde River basin is proposed for critical habitat designation. Overall, seven percent of the proposed critical habitat within the Grand Ronde River Unit is currently unoccupied by the species. Approximately 52 percent of the waters proposed for designation within this unit are located on Federal land. 45. The Grand Ronde River Unit is a low- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit will be between $ 467,000 and $ 580,000. Of this amount, the vast majority, approximately $ 417,000 annually, are forecast to be administrative costs. The remainder of the forecast costs are associated with required project modifications. Specifically, fisheries studies within the unit associated with FCRPS consultations could cost up to $ 19,000 annually. Timber harvest on USFS lands is expected to be another significant source of future project modification costs in this unit ($ 34,000 to $ 87,000 per year resulting from reduced harvest, fisheries studies, and road and culvert costs, and changes in yarding systems). Agricultural irrigation diversion costs could be up to $ 35,000. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. 46. Unit 11: Imnaha/ Snake River Basins - The Imnaha/ Snake Unit extends across Wallowa, Baker, and Union counties in northeastern Oregon and Adams and Idaho counties in western Idaho. The unit contains approximately 306 km ( 190 mi) of proposed critical habitat. All of the proposed habitat within the Imnaha- Snake River Unit is currently occupied by the species. Approximately 51 percent of the waters proposed for designation within this unit are located on Federal land. 47. The Imnaha/ Snake River Unit is a moderate- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit are between $ 559,000 and $ 605,000. Of this amount, the large majority are made up of administrative costs ( approximately $ 544,000, annually). The remainder of the forecast costs are associated with required project modifications. Specifically, fishery studies within the unit associated with FCRPS consultations could cost up to $ 18,000 annually. Timber harvest activities on USFS lands are expected to be another significant category of future project modification costs ($ 10,000 to $ 26,000 per year). Agricultural irrigation diversion related project modification costs could range from zero ES- 21 to $ 11,000. Other activities are individually estimated to each account for less than $ 5,000 dollars per year in project modification costs. 48. Unit 12: Hells Canyon Complex - The Hells Canyon Complex Unit encompasses basins in Idaho and Oregon draining into the Snake River and its associated reservoirs, from Hells Canyon Dam upstream to the confluence of the Weiser River. The Hells Canyon Complex unit includes a total of approximately 1,000 km ( 621 mi) of streams proposed as critical habitat. A relatively high portion ( about 48 percent) of the proposed critical habitat within the Hells Canyon Complex Unit is currently unoccupied by the species. Approximately 47 percent of the waters proposed for designation within this unit are located on Federal land. 49. The Hells Canyon Complex Unit is a relatively moderate- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. It is forecast that total annual costs associated with the bull trout within this unit will be between $ 1.9 million and $ 2.3 million. Of this amount, a majority are expected to be made up of administrative costs ( approximately $ 1.4 million, annually). In addition, significant categories of forecast project modification costs within this unit are associated with timber harvest on USFS lands ($ 92,000 to $ 233,000 per year resulting from reduced harvest, fishery studies, road and culvert costs, and changes in yarding systems), placer mining on USFS land ($ 69,000 associated with requirements for and limitations on allowed stream crossing activity), FERC hydroelectric re- licensing ($ 111,000 to $ 259,000), and BOR reservoir activities ($ 192,000 annually, primarily for study related costs). The BOR reservoirs in the unit include Phillips Reservoir and Thief Valley Reservoir; projected costs are for bull trout related studies. Major FERC- licensed hydroelectric facilities in the unit include Hells Canyon, Brownlee and Oxbow. Agricultural irrigation diversions could experience up to $ 95,000 in annual project modification costs within this unit. Other activities are individually estimated to each account for less than 20,000 dollars per year in project modification costs. The Hells Canyon complex is one of two units identified in this study as a setting where bull trout related project modifications could have a significant impact on a small placer mining business, the other is the John Day River Basin ( Unit 8). 50. Unit 13: Malheur River Basin - The Malheur Unit is in the Malheur River Basin in eastern Oregon, in Grant, Baker, Harney, and Malheur counties. A total of 389 km ( 241 mi) of streams and two reservoirs are proposed for critical habitat. About 25 percent of the proposed critical habitat within the Malheur River Unit is currently unoccupied by the species. Approximately 63 percent of the waters proposed for designation within the Malheur River Unit are located on Federal land. 51. The Malheur River Unit is the second highest cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit are between $ 2.0 million and $ 2.1 million. Project modification costs make up a small portion of these costs, between $ 179,000 and $ 268,000 annually. The rest of the forecast costs are associated with administrative requirements. Major categories of forecast project modification costs within this unit are associated with ES- 22 timber harvest on USFS lands ($ 33,000 to $ 83,000 per year) and BOR reservoir activities ($ 133,000 annually). The BOR costs are for research as well as trap and haul fish passage that is ongoing at Beulah Reservoir on the Malheur River, and estimated research costs at Warm Springs Reservoir, which is currently unoccupied by bull trout. Possible reductions in agricultural irrigation diversions could cost from zero to $ 34,000 annually . Other activities are individually estimated to each account for less than $ 5,000 per year in project modification costs. 52. Unit 14: Coeur d'Alene Lake Basin - The Coeur d'Alene Lake Basin Unit in Idaho is broken into two subunits. The Coeur d'Alene Lake subunit lies within Kootenai, Shoshone, Benewah and Bonner counties. The St. Joe River subunit includes streams in Shoshone, Benewah, and Latah counties, Idaho. Thirty stream reaches or tributaries ( 677 km ( 421 mi)) and lakes comprising 12,727 ha ( 31,450 ac) of surface area are proposed as critical habitat within this unit. Of this, a relatively high portion ( 46 percent) is currently unoccupied by the species. Approximately 58 percent of the waters proposed for designation within this Unit are located on Federal land. 53. The Coeur d'Alene Lake Unit is relatively low cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit are between $ 429,000 and $ 693,000. A large share of this amount, approximately $ 287,000 annually, is forecast to be made up of administrative costs. In addition, major categories of forecast project modification costs within the unit are associated with timber harvest on USFS lands ($ 97,000 to $ 245,000 per year resulting from reduced harvest, fishery studies, road and culvert costs, and changes in yarding systems), and FHWA bridge and road work ($ 23,000 associated with limitations on in- stream work periods). Modifications to agricultural irrigation diversions could result in costs from zero to $ 100,000. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. 54. Unit 15: Clearwater River Basin - The Clearwater River Unit includes 3,063 km ( 1,904 mi) of streams and 6,722 ha ( 16,611 ac) of lakes proposed as critical habitat for bull trout in north- central Idaho. This large unit extends from the Snake River confluence at Lewiston on the west to headwaters in the Bitterroot Mountains along the Idaho/ Montana border on the east. About 13 percent of the proposed critical habitat within the Clearwater River Unit is currently unoccupied by the species. Approximately 78 percent of the waters proposed for designation within the Unit are located on Federal land. 55. Total forecast costs associated with consultation on bull trout within this unit are between $ 1.0 million and $ 1.7 million annually. Of this amount, approximately $ 572,000 is associated with administrative costs. In addition, major categories of forecast project modification costs within this unit are associated with timber harvest on USFS lands ($ 252,000 to $ 635,000 per year resulting from reduced harvest, fishery studies, road and culvert costs and changes in yarding systems), recreational suction mining on USFS land ($ 115,000 associated with reduced availability of stream access due to seasonal closures), highway bridge and road work ($ 25,000), and USFS management activities ($ 35,000 ES- 23 annually). Agricultural irrigation diversion project modification costs could range from zero up to $ 259,000 annually. These costs may result from reductions in irrigation deliveries. Other activities are individually estimated to each account for less than $ 15,000 dollars per year in project modification costs. 56. Although the proposed Clearwater River Basin Critical Habitat Unit is forecast to experience significant costs associated with the bull trout, these costs should be viewed in light of the large size of the proposed unit. In fact, the Clearwater Unit is one of the lowest cost of the proposed units, in terms of forecast costs per river mile of habitat proposed for designation. 57. Unit 16: Salmon River Basin - The Salmon River basin is a geographically large unit that extends across central Idaho from the Snake River to the Montana border. The critical habitat unit includes 7,688 km ( 4,777 mi) of streams extending across portions of Adams, Blaine, Custer, Idaho, Lemhi, Nez Perce, and Valley counties in Idaho. About six percent of the proposed critical habitat within the Salmon River Unit is currently unoccupied by the species. Approximately 86 percent of the waters proposed for designation within the Unit are located on Federal land. 58. Forecast total annual costs associated with the bull trout within this unit are between $ 2.1 million and $ 3.3 million. Of this amount, approximately $ 1.3 million is associated with administrative costs, with the rest made up of project modification costs. Major categories of forecast project modification costs are associated with timber harvest on USFS lands ($ 465,000 to $ 1.2 million per year resulting from reduced harvest, fishery studies, road and culvert costs and changes in yarding systems), highway bridge and road work ($ 57,000), and USFS general forest management activities ($ 65,000 annually). The cost of modifications to agricultural irrigation water deliveries could range from zero up to $ 479,000 annually. Costs associated with mining activities at Hecla Mining Company's Grouse Creek and Thompson Creek mines are estimated at $ 132,000 annually. Other activities are individually estimated to each account for less than $ 25,000 dollars per year in project modification costs. 59. Although the proposed Salmon River Basin Critical Habitat Unit has significant forecast costs associated with the bull trout, these costs should be viewed in light of the large size of the proposed unit. In fact, the Salmon River Unit is also one of the lowest cost of the proposed units, in terms of forecast costs per river mile of habitat proposed for designation. 60. Unit 17: Southwest Idaho River Basins - The Southwest Idaho Unit includes a total of approximately 2,792 km ( 1,735 mi) of streams in the Boise, Payette, and Weiser River basins. A number of southern Idaho counties are wholly or partially within this unit, including Ada, Adams, Boise, Camas, Canyon, Elmore, Gem, Payette, Valley, and Washington counties. The counties within the southern Idaho unit include both a significant portion of productive agricultural land as well as the largest population center in the state ( the Boise Valley). About 24 percent of the proposed critical habitat within the Southwest ES- 24 Idaho Unit is currently unoccupied by the species. Approximately 78 percent of the proposed streams and 66 percent of proposed lakes and reservoirs within the Southwest Idaho River Basins Unit are located on Federal land. 61. The Southwest Idaho River Basins Unit is a relatively low- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit are between $ 1.0 million and $ 1.9 million. Total administrative costs are forecast to be a relatively small portion of this total ($ 328,000 annually). The remainder of the forecast costs are expected to result from forecast project modifications. Specifically, project modification costs within this unit are forecast to be associated with timber harvest on USFS lands ($ 309,000 to $ 781,000 per year resulting from reduced harvest, fishery studies, road and culvert costs and changes in yarding systems) and BOR reservoir activities ($ 263,000 annually). Major BOR reservoirs in this unit include Anderson Ranch and Arrowrock Reservoirs on the Boise River, Cascade Reservoir on the North Fork Payette, and Deadwood Reservoir on the Payette River. Forecast project modification costs include bull trout life- cycle studies and monitoring at all the reservoirs, and trap and haul passage around the Boise River reservoirs. Costs associated with FERC relicensing at the Lucky Peak facility on the Boise River, and power facilities at the Cascade impoundment, are expected to cost between $ 31,000 and $ 58,000 annually. Modifications to agricultural irrigation diversions could range from zero to $ 318,000 annually. These costs could potentially be associated with reductions in irrigation water withdrawals. Other activities are individually estimated to each account for less than $ 30,000 dollars per year in project modification costs. 62. Unit 18: Little Lost River Basin - The Little Lost River Unit is within Butte, Custer, and Lemhi counties in east- central Idaho. Approximately 184.6 km ( 115.4 mi) of stream habitat in the Little Lost River Basin is proposed for critical habitat designation. About eight percent of the proposed critical habitat within the Little Lost River Unit is currently unoccupied by the species. Approximately 76 percent of the proposed streams within the Little Lost River Basin Unit are located on Federal land. 63. The Little Lost River Unit is forecast to be a relatively inexpensive unit compared to others in the designation, and is a moderate- cost unit in terms of forecast costs per river mile of habitat proposed for designation. It is estimated that total annual costs associated with the bull trout within this unit will be between $ 150,000 and $ 176,000. Of this amount, a large share, approximately $ 136,000 annually, is forecast to be comprised of administrative costs, with the remainder made up of project modification costs. The largest category of project modification costs within this unit is forecast to be associated with timber harvest on USFS lands ($ 10,000 to $ 24,000 per year). Project modifications to agricultural irrigation diversions could result in costs from zero to $ 10,000 annually. Other activities are individually estimated to each account for less than $ 5,000 dollars per year in project modification costs. 64. Unit 19: Lower Columbia River Basin - The Lower Columbia Unit consists of portions of the Lewis, White Salmon, and Klickitat Rivers, and associated tributaries in ES- 25 southwestern and south- central Washington. The unit extends across Clark, Cowlitz, Klickitat, Skamania, and Yakima counties. Approximately 340 km ( 210 mi) of streams and three reservoirs covering 5,054 ha ( 12,488 ac) are proposed for critical habitat designation. About 20 percent of the proposed critical habitat within the Lower Columbia River Unit is currently unoccupied by the species. A low portion ( 18 percent) of the proposed streams and 29 percent of the proposed lakes and reservoirs within the Lower Columbia River Basin Unit are located on Federal land. 65. When forecast total costs for this unit are viewed in light of its size, the Lower Columbia River Basins Unit is a moderate- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. It is estimated that total annual costs associated with the bull trout within the unit will be between $ 385,000 to $ 494,000. Total administrative costs associated with the consultation process are estimated to be a relatively large fraction of these costs ($ 304,000 annually). In addition, project modification costs are forecast to be associated with FERC hydroelectric facility re- licensing activities ($ 67,000 to $ 153,000 annually). These FERC re- licensing costs are for the significant hydroelectric developments on the Lewis River, including Yale, Merwin, Swift No. 1, and Swift No. 2. These costs are projected to include study costs, trap and haul passage, and habitat acquisition. Swift No, 2 is one of two hydroelectric projects identified in this study where bull trout- related project modifications could have a significant impact on a small business; the other is Box Canyon in the Northeast Washington River Basin ( Unit 22). Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. 66. Unit 20: Middle Columbia River Basin - The Middle Columbia River unit encompasses the entire Yakima River basin located in south central Washington, draining approximately 15,900 square km ( 6,155 square mi). The basin occupies most of Yakima and Kittitas counties, about half of Benton County, and a small portion of Klickitat County. Approximately 846 km ( 529 mi) of stream habitat and 6,066 ha ( 14,986 ac) of lake and reservoir surface area are proposed as critical habitat within this unit. About 13 percent of the proposed critical habitat within the Middle Columbia River Unit is currently unoccupied by the species. Approximately 44 percent of the waters proposed for designation within the Middle Columbia River Basin Unit are located on Federal land. 67. The Middle Columbia River Unit is a relatively low- cost unit in terms of cost per stream mile. Forecast costs associated with the bull trout within this unit are between $ 391,000 and $ 494,000 annually. Of this amount, a very small portion, approximately $ 50,000 annually, will be associated with the administrative costs of the consultation process, while the remainder will be associated with project modifications. While there are projected to be project modification costs associated with timber harvest activities ( through consultation with the USFS; estimated to be between $ 36,000 and $ 91,000 annually), the majority of forecast costs for this unit are associated with dam and reservoir operations. The BOR operates a system of five dams in this basin ( Cle Elum Lake, Kachess Lake, Keechelus Lake, Tieton Dam, and Bumping Lake) which provide power and irrigation for this agriculturally important region. It is estimated that project modification costs ( periodic trap- ES- 26 and- haul passage to allow genetic interchange between isolated bull trout populations) at the BOR operated impoundments in the unit will cost approximately $ 290,000 per year. Other activities are individually estimated to account for a small portion of forecast annual project modification costs. 68. TheMiddle Columbia River Unit is a relatively low- cost unit in terms of cost per stream mile. 69. Unit 21: Upper Columbia River Basin - The Upper Columbia River Basin includes three subunits in central and northern Washington: the Wenatchee River subunit in Chelan County; the Entiat River subunit in Chelan County; and the Methow River subunit in Okanogan County. A total of 909.7 km ( 565.4 mi) of streams and 1,010 ha ( 2,497 ac) of lake surface area are proposed for critical habitat. About nine percent of the proposed critical habitat within the Upper Columbia River Unit is currently unoccupied by the species. Approximately 58 percent of the proposed streams and 41 percent of the proposed lakes and reservoirs within the Upper Columbia River Basin Unit are located on Federal land. 70. The Upper Columbia River Basins Unit is a low- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. Forecast costs associated with the bull trout within this unit are between $ 196,000 to $ 505,000 annually. Total administrative costs associated with the consultation process are estimated to be $ 122,000, with the remainder of the forecast costs made up of project modification requirements. Major categories of forecast project modification costs within this unit are associated with FCRPS fisheries studies ( zero to $ 155,000 per year), and USFS timber harvest activities ($ 57,000 to $ 144,000 annually resulting from reduced harvest, fishery studies, road and culvert costs and changes in yarding systems). The FCRPS fisheries studies are for bull trout radio telemetry, snorkel and general monitoring study costs in the Entiat, Methow, and Wenatchee Rivers. In addition, modifications to agricultural irrigation diversions could result in costs from zero to $ 59,000 annually. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. 71. Unit 22: Northeast Washington River Basins - The Northeast Washington unit includes bull trout above Chief Joseph Dam on the Columbia River. A total of 373.1 km ( 231.9 mi) of streams and 1,166 ha ( 2,880 ac) of lake surface area are proposed as critical habitat within this unit. A high proportion ( 54 percent) of the proposed critical habitat within the Northeast Washington River Basins Unit is currently unoccupied by the species, and approximately 58 percent of the proposed streams and reservoirs within this unit are located on Federal land. 72. The Northeast Washington River Basins Unit is forecast to be a relatively high- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. Forecast costs associated with the bull trout within this unit are between $ 965,000 to $ 1.4 million annually. Total annual administrative costs are estimated to be a large share of these costs ($ 676,000), with the remainder associated with project modifications. A major category of ES- 27 annual project modification costs within this unit involves FERC hydroelectric facility re-licensing activities ( up to $ 540,000 annually). The estimated FERC re- licensing costs are related to two major hydroelectric facilities on the Pend Orielle River: Box Canyon and Boundary. The Box Canyon re- licensing terms are currently in continuing settlement negotiations, and likely costs specific to this facility are not currently available. However, a recent FERC environmental impact statement ( EIS) estimates that the present value of bull trout related project modifications ( including habitat acquisition) could total upwards of $ 60 million for this relatively small ( 60 MW) facility. Box Canyon is one of two hydroelectric projects identified in this study where bull trout- related project modifications could have a significant impact on a small business; the other is Swift No. 2 in the Lower Columbia River Basin ( Unit 19). Modifications to agricultural irrigation diversions could impose costs from zero to $ 46,000 annually. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. 73. Unit 23: Snake River Basin in Washington - The Snake River Washington Unit includes two critical habitat subunits located in southeast Washington: the Tucannon River subunit located in Columbia and Garfield counties, and the Asotin Creek subunit within Garfield and Asotin counties. A total of 326 km ( 203 mi) of stream reaches are proposed as critical habitat within this unit. About 23 percent of the proposed critical habitat within the Snake River Basin in Washington Unit is currently unoccupied by the species. Approximately 52 percent of the proposed streams within the Snake River Basin Unit are located on Federal land. 74. The Snake River Basin Unit is a relatively low- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. Forecast costs associated with the bull trout within the unit will be between $ 230,000 to $ 287,000. Total annual administrative costs associated with the bull trout are estimated to be a large portion of this total ($ 201,000). The major category of project modification costs within this unit is forecast to be associated with USFS timber harvest activities ($ 21,000 to $ 53,000 annually). Agricultural irrigation diversions could see up to $ 22,000 in annual project modification costs within this unit. Other activities are estimated to each account for less than $ 5,000 dollars per year in project modification costs. 75. Unit 24: Columbia River - This unit is located in the states of Oregon and Washington and includes Clatsop, Columbia, Multnomah, Hood River, Wasco, Sherman, Gilliam, Morrow, and Umatilla counties in Oregon and Pacific, Wahkiakum, Cowlitz, Clark, Skamania, Klickitat, Benton, Walla Walla, Franklin, Yakima, Grant, Kittitas, Chelan, Douglas, and Okanogan counties in Washington. All of this stretch of the Columbia River is currently considered occupied by the bull trout. A relatively low share of the land adjacent to the river in this unit is made up of Federally managed lands ( approximately 39 percent). 76. The Columbia River Unit is a relatively low- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. Forecast total costs associated with the bull trout within this unit will be between $ 243,000 to $ 504,000 annually. Total annual ES- 28 administrative costs associated with this unit are relatively low ($ 50,000). The major category of annual project modification costs within the unit are forecast to be associated FERC hydroelectric facility re- licensing activities ( up to $ 362,000 annually). Major FERC-licensed hydroelectric projects on the mainstem Columbia River include Priest Rapids, Rocky Reach, and Wells. These very large facilities are operated by PUD's. Other activities are individually forecast to account for less than $ 15,000 dollars per year in project modification costs. 77. Unit 25: Snake River - The lower Snake River is located in Washington ( Franklin, Walla Walla, Columbia, Whitman, and Asotin counties) from its mouth to the confluence with the Clearwater River at the cities of Clarkston, Washington and Lewiston, Idaho. The Snake River forms the border between Washington and Idaho from Clarkston/ Lewiston upstream to the Oregon border. The Snake River forms the boundary between Idaho and Oregon from that point upstream to the limit of this critical habitat unit. This portion of the Snake River is within Nez Perce, Idaho, Adams, and Washington counties in Idaho, and Wallowa, Baker, and Malheur counties in Oregon. About 20 percent of the proposed critical habitat within the Snake River Unit is currently unoccupied by the species. Approximately 50 percent of the habitat proposed for designation within the Snake River Unit is located on Federal land. 78. The Snake River Unit is a relatively low- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. Forecast costs associated with the bull trout within this unit are approximately $ 135,000. Administrative costs associated with the consultation process are estimated to be nearly all of that amount, or $ 125,000 annually. Small Business Effects 79. Under the Regulatory Flexibility Act ( RFA) ( as amended by the Small Business Regulatory Enforcement Fairness Act ( SBREFA) of 1996), whenever a Federal agency is required to publish a notice of rulemaking for any proposed or final rule, it must prepare and make available for public comment a regulatory flexibility analysis that describes the effect of the rule on small entities ( i. e., small businesses, small organizations, and small government jurisdictions). The following summarizes the potential effects of critical habitat designation on small entities: Reductions in contractual USFS water deliveries could significantly impact five ranching/ farming operations annually. However, the location of the reduction in water deliveries within the critical habitat designation is uncertain. Small hydroelectric producers in Washington, Oregon, Idaho and Montana could be affected by project modification costs at the time of facility re- licensing. Specifically, the resulting project modifications could have a significant economic impact on the financial operations of Cowlitz County public utility district ( PUD) ( Unit 19 - Lower Columbia River) and Pend Orielle County PUD ( Unit 22 - Northeast Washington River). ES- 29 • Section 7- related costs associated with instream work is expected to affect approximately 15 placer mines annually in the John Day River Basin ( Unit 8) and Hells Canyon Complex ( Unit 12). While the financial characteristics of these mining operations are unknown, this analysis assumes the economic effect will be significant for those operations that are impacted. Energy Industry Impacts 80. Pursuant to Executive Order No. 13211, Federal agencies are required to submit a summary of the potential effects of regulatory actions on the supply, distribution and use of energy. Two criteria are relevant to this analysis: 1) reductions in electricity production in excess of 1 billion kilowatt- hours per year or in excess of 500 megawatts ( MWs) of installed capacity and 2) increases in the cost of energy production in excess of one percent. The constraints placed on energy production within the region from compliance with bull trout section 7 consultations will not result in significant decreases in production or increases in energy costs within the region. Changes From Draft Economic Analysis 81. Information supplied though public comments to the Draft Economic Analysis along with additional information from Action agency and Service personnel on issues raised through public comment led to several changes to the analysis. This Final Economic Analysis contains the following significant changes from the draft report. 1) Additional information on Habitat Conservation Plans ( HCPs) currently under development within the proposed designation has been incorporated. Additional costs on the order of one million dollars annually have been added to the estimated costs reported. 2) The BOR supplied extensive comments on current and potential costs associated with consultation on its impoundments. Costs associated with potential project modifications to Yakima Drainage dams ( as well as for other BOR impoundments within the proposed designation) have been reduced in response to the new BOR information. 3) Information from Hecla Mining Company identified additional consultation- related costs for the Hecla Grouse Creek and Thompson Creek mines. These costs have been included in the section 4 discussion of USFS mining activity. 4) Information from USFS personnel from the Wallowa/ Whitman National Forest identified impacts associated with limitations on in- stream work windows for placer mining operations as baseline State of Oregon regulations that are independent of bull trout section 7 consultation. Estimated impacts to Oregon placer mining have been adjusted accordingly. ES- 30 5) Additionally, corrections to minor errors within the report, not impacting final cost estimates, have been made in response to public comments. Caveats to Economic Analysis 82. Exhibit ES. 10 presents the key assumptions of this economic analysis, as well as the potential direction and relative scale of bias introduced by the assumptions. 83. These caveats below describe factors that introduce uncertainty into the results of this analysis. ES. 10 CAVEATS TO THE ECONOMIC ANALYSIS Key Assumption Projected USFS timber harvest activity is based on recent regional history and ignores the declining long- term trend of the industry. USFS water diversion reductions occur annually and representative water costs reflect the high- end of water lease rates in Washington. Cost of USFS water diversion reductions and timber harvest project modifications are distributed across the units in proportion to USFS non- wilderness acreage. While this may have no effect on the total cost estimate, it may have an effect on the unit cost estimate. Total costs of providing technical assistance is expected to be small relative to other economic impacts; therefore, this analysis does not quantify the instances and costs of technical assistance efforts. Project modifications incorporating measures suggested by the Service and voluntarily agreed to by the applicant during the informal consultation process in order to minimize impact to the bull trout and/ or its habitat are not quantified in this analysis. Amortization of fishery- related capital investments are based on the life of the project rather than a shorter revenue recovery period. Changes in hydroelectric power revenues attributable to reductions in operational flexibility at Libby and Hungry Horse dams is not quantified Most of the project modification costs will either be borne directly by or passed onto the Federal government. The FPA, the Pacific Northwest Electric Power Planning and Conservation Act, and fisheries management directives ( Northwest Forest Plan, INFISH and PACFISH) provide baseline protection. Project modification costs allocated between bull trout and other listed species. Limited consultation with the NRCS is anticipated and based on a the record of past formal and informal consultation activity on the bull trout Effect on Cost Estimate + + +/- - - - - +/- +/- +/- - -: This assumption may result in an underestimate of real costs. + : This assumption may result in an overestimate of real costs. +/-: This assumption has an unknown effect on estimates. ES- 31 Estimated Cost of the Final Designation 84. The analysis contained in this report is consistent with the designation as described in the proposed rule; 5 however, the Service is expected to exclude some proposed areas of habitat to arrive at a final designation. The purpose of this section is to detail the expected changes to the proposed designation and show the implication of these changes on estimated consultation and project modification costs. 85. Exhibit ES. ll compares the spatial extent of the proposed and expected final designations for bull trout critical habitat for both river and stream miles and lake and reservoir acres. Overall, 1,925 miles of rivers and streams and approximately 55,000 acres of lakes and reservoirs are expected to be excluded from critical habitat in the final designation. The greatest reductions in critical habitat stream miles are expected to occur in the Deschutes River Unit ( 60.5 percent reduction), Hood River Unit ( 33.2 percent), Southwest Idaho River Basins Unit ( 32.8 percent), and the Hells Canyon Complex Unit ( 21.3 percent). Most of the reductions in lake and reservoir critical habitat acres are expected to occur in the Deschutes River, Southwest Idaho River Basins and Malheur River Units, all with more than a 70 percent reduction in designated lake and reservoir critical habitat compared to the original proposed designation.

As noted, the costs reported in the body of this report are consistent with the proposed designation. Expected changes to the proposed designation and the impact of these exclusions on costs are summarized in Exhibit ES. 12, where estimates of annual section 7- related consultation costs for both the proposed and expected final bull trout critical habitat designations are shown. The expected changes to the final designation impacts estimated costs in two ways. 87. First, where future consultation and project modification costs were estimated for dams and reservoirs located within stream reaches that are expected to be excluded from the final critical habitat designation, the costs associated with these anticipated consultations are removed. Three critical habitat units have dams and reservoirs located on waters expected to be excluded in the final designation. The previously quantified costs associated with consultations on Lucky Peak and Cascade Dams and Reservoirs, and Warm Springs, Crane Prairie, and Wickiup Reservoirs have therefore been removed from the forecast total costs associated with the final critical habitat designation. Costs associated with consultations on Lucky Peak and Cascade Dams and Reservoirs have been removed from estimates for the Southwest Idaho River Basins Units, costs associated with consultation on Warm Springs Reservoir have been removed from estimates for the Malheur River Unit, and costs associated with consultations on Crane Prairie and Wickiup Reservoirs have been removed from estimates for the Deschutes River Unit. 88. Second, because the Service is expected to exclude areas of unknown occupancy from the final designation, the spatial extent of unoccupied habitat in each critical habitat ES- 33 unit is adjusted to reflect the expected final designation ( see Appendix F, Exhibit F. 11), and the forecast costs of the expected final designation reflect these changes. 89. Exhibit ES. 12 presents a summary of the annualized forecast total costs, by unit, likely to be associated with the final critical habitat designation over the next ten years. Overall, the removal of waters from the proposed to the expected final bull trout designation is expected to lower forecast section 7- related consultation and project modification costs by approximately $ 18 to $ 24 million over the next ten years ( nine percent). In six units where no changes in the proposed designation were made, there is no change in forecast costs. As a percentage of unit costs, the greatest reduction in forecast costs resulting from the exclusions is expected to occur in the Deschutes River Basin Unit, where forecast costs of the expected final designation are 43 to 55 percent of the costs originally forecast for the proposed designation. 90. The economic impacts associated with the final designation, discounted to present value using a rate of seven percent, are forecast to range from approximately $ 180 to $ 245 million over the next ten years, or $ 18.0 to $ 24.5 million annually. Total costs associated with the final designation for the Klamath Distinct Population Segment of bull trout are forecast to range from approximately $ 5 million to $ 7 million over the next ten years ($ 0.5 to 0.7 million annually), while costs associated with the final designation for the Columbia Distinct Population Segment of bull trout are forecast to range from approximately $ 175 million $ 235 million ($ 17.5 to $ 23.5 million annually). 91. These costs will be incurred primarily by Federal agencies responsible for section 7 consultations ( approximately 65 percent of forecast costs) and the Service ( approximately five to ten percent of forecast costs); private entities will incur the remaining 25 to 30 percent. Project modification costs account for as much as 50 to 60 percent of forecast costs, and administrative costs the remaining 40 to 50 percent. Dam and reservoir- related consultations, including power facility re- licensing, account for approximately 42 percent of forecast project modification costs ( excluding the cost associated with reduced irrigation diversions). Timber harvest, irrigation diversions, habitat conservation plans, and mining account for 20 percent, 12 percent, nine percent, and three percent of forecast project modification costs, respectively. 92. The main text of the report discusses impacts to small businesses expected under the rulemaking as proposed. Impacts to small businesses are primarily related to potential reductions in USFS water deliveries to farmers/ ranchers, project modifications triggered during hydroelectric facility re- licensing, and costs associated with activity restrictions for placer mining. Under the final designation, the reduction in small business impacts would parallel the extent to which these activities occur in habitat removed from the final designation and losses related to these activities reduced.

ES- 36 INTRODUCTION AND BACKGROUND SECTION 1 93. In November 2002, the Service proposed to designate critical habitat for the Columbia River and Klamath River DPSs of bull trout ( Salvelinus confluentus), hereafter " bull trout." 6 The purpose of this report is to identify and analyze potential economic impacts associated with the proposed critical habitat designation. This report was prepared by Bioeconomics, Inc. of Missoula, Montana. 94. Section 4( b)( 2) of the Act requires the Service to designate critical habitat on the basis of the best scientific data available, after taking into consideration the economic impact, and any other relevant impact, of specifying any particular area as critical habitat. The Service may exclude areas from critical habitat designation when the benefits of exclusion outweigh the benefits of including the areas within critical habitat, provided the exclusion will not result in extinction of the species. 95. Under the listing of a species, section 7( a)( 2) of the Act requires Federal agencies to consult with the Service in order to ensure that activities they fund, authorize, permit, or carry out are not likely to jeopardize the continued existence of the species. The Service defines jeopardy as any action that would appreciably reduce the likelihood of both the survival and recovery of the species. For designated critical habitat, section 7( a)( 2) also requires Federal agencies to consult with the Service to ensure that activities they fund, authorize, permit, or carry out do not result in destruction or adverse modification of critical habitat. Adverse modification of critical habitat is currently construed as any direct or indirect alteration that appreciably diminishes the value of critical habitat for conservation of a listed species. 6 On January 26,2001, the Alliance for the Wild Rockies, Inc. and Friends of the Wild Swan, Inc. filed a lawsuit in the U. S. District Court of Oregon challenging the Service's failure to designate critical habitat for bull trout. The Service entered into a settlement agreement on January 14, 2002, which stipulated that the Service would make critical habitat determinations for five populations of bull trout ( Civil Case No: CV 01- 127- JO). The Service has proposed critical habitat for the Columbia River and Klamath River populations, which are the subject of this analysis. 1- 1 1.1 Description of Species and Habitat7 96. Bull trout { Salvelinus confluentus, family Salmonidae) is a char native to waters of western North America. The historic range of bull trout includes major river basins in the Pacific Northwest from about 41° north to 60° north latitude, extending south to the McCloud River in northern California and the Jarbidge River in Nevada, and north to the headwaters of the Yukon River in Northwest Territories, Canada. To the west, bull trout range includes Puget Sound, various coastal rivers of British Columbia, Canada, and southeast Alaska. Bull trout occur in portions of the Columbia River and Snake River basins, extending east to headwater streams in Montana and Idaho, and into Canada. Bull trout also occur in the Klamath River basin of south- central Oregon. East of the Continental Divide in Canada, the bull trout's range includes the headwaters of the Saskatchewan River in Alberta, and the MacKenzie River system in Alberta and British Columbia. 97. Bull trout were first described as Salmo spectabilis by Girard in 1856 from a specimen collected on the lower Columbia River near The Dalles, Oregon, and subsequently described under a number of names such as Salmo confluentus and Salvelinus malma. Bull trout and Dolly Varden ( Salvelinus malma) were previously considered a single species. However, in 1980, the American Fisheries Society formally recognized bull trout and Dolly Varden as separate species. Two of the most useful characteristics in separating the two species are the shape and size of the head. The head of bull trout is more broad and flat on top, unlike Dolly Varden. Bull trout have an elongated body and large mouth, with the maxilla ( jaw) extending beyond the eye and with well- developed teeth on both jaws and head of the vomer ( a bone in teleost fishes that form the front part of the roof of the mouth and often bears teeth). Bull trout have 11 dorsal fin rays, nine anal fin rays, and the caudal fin is slightly forked. Although they are often olive green to brown with paler sides, color is variable with locality and habitat. 98. Bull trout exhibit both resident and migratory life history strategies. Resident bull trout complete their entire life cycle in the tributary streams where they spawn and rear. Migratory bull trout spawn in tributary streams where juvenile fish rear from one to four years before migrating to either a larger river or lake, where they spend their adult life, returning to the tributary stream only to spawn. These migratory forms occur in areas where conditions allow for movement from upper watershed spawning streams to larger downstream waters that contain greater foraging opportunities. Bull trout that migrate to a downstream river are referred to as " fluvial" fish, while the term " adfluvial" is used to describe fish that migrate to a lake or reservoir. Resident and migratory forms may spawn in the same areas and either form can produce resident or migratory offspring. 7 Information on the bull trout and its habitat is taken from the U. S. Fish and Wildlife Service, Proposed Designation of Critical Habitat for the Klamath River and Columbia River Distinct Population Segments of Bull Trout, November 29, 2002 ( 67 FR 71235- 71284). 1- 2 99. The Klamath River population segment consists of bull trout in the Upper Klamath Lake, Sprague River, and Sycan River watersheds in Oregon. Historical records suggest that bull trout were once widely distributed and exhibited diverse life- history traits in the Klamath River basin. Currently, bull trout in this basin are non- migratory fish that are confined to headwater streams. The local populations that remain reside in an estimated 21 percent of the historic range of bull trout in the Klamath River basin, and they are isolated from one another. 100. The Columbia River population segment includes bull trout residing in portions of Oregon, Washington, Idaho, and Montana. The Bull Trout Draft Recovery Plan ( Draft Recovery Plan) ( Service 2002) identifies 22 recovery units within the Columbia River basin: the Willamette River ( upper tributaries including the McKenzie River), Lower Columbia River ( principally the Lewis, White Salmon, and Klickitat Rivers), Hood River, Deschutes River, Odell Lake, John Day River, Umatilla and Walla Walla Rivers, Middle Columbia River ( principally the Yakima River), Snake River ( including Asotin Creek and Tucannon River), Grande Ronde River, Clearwater River, Salmon River, Little Lost River, Imnaha River, Hells Canyon ( including Powder River), Malheur River, Southwest Idaho, Upper Columbia River ( principally the Wenatchee, Entiat, and Methow Rivers), Northeast Washington, Clark Fork River, Kootenai River, and Coeur d'Alene Lake. Bull trout are estimated to have once occupied about 60 percent of the Columbia River basin; they presently occur in approximately 45 percent of their historic range. Although still somewhat widely distributed in the Columbia River basin, bull trout occur in low numbers in many areas and populations are considered depressed or declining across much of their range. 101. Many factors have contributed to the decline of bull trout in the Columbia and Klamath River basins. However, several appear to be particularly significant: ( 1) fragmentation and isolation of local populations due to dams and water diversions that have eliminated habitat, altered water flow and temperature regimes, and impeded migratory movements; ( 2) degradation of spawning and rearing habitat in upper watershed areas, particularly alterations in sedimentation rates and water temperature resulting from past forest and rangeland management practices and intensive development of roads; and ( 3) the introduction and spread of non- native species, particularly brook trout ( Salvelinusfontinalis) and lake trout ( Salvelinus namaycush), which compete with bull trout for limited resources and, in the case of brook trout, hybridize with bull trout. 102. Bull trout have more specific habitat requirements than most other salmonids. Habitat components that influence bull trout distribution and abundance include water temperature, cover, channel form and stability, spawning and rearing substrate conditions, and migratory corridors. 103. Bull trout are found primarily in cold streams; water temperatures above 15° Celsius ( C) ( 59° Fahrenheit ( F)) are believed to limit bull trout distribution. Adult bull trout have been observed in large rivers throughout the Columbia River basin in water temperatures up to 20° C ( 68° F); however, there are documented steady and substantial declines in 1- 3 abundance in stream reaches where water temperature ranged from 15° to 20° C ( 59° to 68° F). In large rivers, bull trout are often observed " dipping" into the lower reaches of tributary streams, and it is suspected that cooler waters in these tributary mouths may provide important thermal refugia, allowing them to forage, migrate, and overwinter in waters that would otherwise be, at least seasonally, too warm. 104. Preferred spawning habitat consists of low- gradient stream reaches with loose, clean gravel, and water temperatures that range from 4° to 10° C ( 39° to 51° F). Such areas are often associated with cold- water springs or groundwater up- welling. Because bull trout eggs incubate about seven months in the gravel, they are especially vulnerable to fine sediments and water quality degradation. Increases in fine sediment appear to reduce egg survival and emergence. Juveniles are likely similarly affected, as they also live on or within the stream bed cobble. 105. Throughout their lives, bull trout require complex forms of cover, including large woody debris, undercut banks, boulders, and pools. Bull trout are opportunistic feeders, with food habits that are primarily a function of size and life- history strategy. Resident and juvenile migratory bull trout prey on terrestrial and aquatic insects, macro- zooplankton, and small fish. Adult migratory bull trout feed almost exclusively on other fish. 106. The ability to migrate is important to the persistence of bull trout. Maintaining the full complement of bull trout life history forms appears to be important for long- term population persistence in a dynamic and unpredictable environment. Migratory bull trout become much larger than resident fish in the more productive waters of larger streams and lakes, leading to increased reproductive potential. Migration also results in increased dispersion of the population which facilitates gene flow among local populations when individuals from different local populations interbreed, stray, or return to non- natal streams. Local populations that are extirpated by catastrophic events may also become re- established by bull trout migrants. 107. Introduced brook trout threaten bull trout through hybridization, competition, and possibly predation. Hybridization between brook trout and bull trout has been reported in Montana, Oregon, Washington, and Idaho. In addition, brook trout mature at an earlier age and have a higher reproductive rate than bull trout. This difference appears to favor brook trout over bull trout when they occur together, often leading to the decline or extirpation of bull trout. Brook trout also appear to adapt better to degraded habitat than bull trout and are more tolerant of high water temperatures. Non- native lake trout also negatively affect bull trout. In a study of 34 lakes in Montana, Alberta, and British Columbia, lake trout appeared to limit foraging opportunities and reduce the distribution and abundance of migratory bull trout in mountain lakes. 108. The Service determined the primary constituent elements of bull trout habitat from studies of their habitat requirements, life history characteristics, and population biology, as outlined above. These primary constituent elements are: 1- 4 Permanent water and associated substrate having low levels of contaminants such that normal reproduction, growth and survival are not inhibited; Water temperatures ranging from 2° to 15° C ( 37° to 59° F). Adequate thermal refugia may be necessary for persistence of bull trout if water temperatures commonly exceed this range. Specific temperatures within this range will vary depending on bull trout life history stage and form, geography, elevation, diurnal and seasonal variation, shade, such as that provided by riparian habitat, and local groundwater influence; • Complex stream channels with features such as woody debris, side channels, pools, and undercut banks to provide a variety of depths, velocities, and instream structures; • Substrates of sufficient amount, size, and composition to ensure success of egg and embryo overwinter survival, fry emergence, and young- of- the- year and juvenile survival. A minimal amount of fines less than 0.63 cm ( 0.25 in) in diameter and minimal substrate embeddedness are characteristic of these conditions; • A natural hydrograph, including high, low, peak, and base flows within historic ranges or, if regulated, a hydrograph that demonstrates the ability to support bull trout populations; • Springs, seeps, groundwater sources, and subsurface water connectivity to contribute to water quality and quantity; • Migratory corridors with minimal physical, biological or chemical barriers between spawning, rearing, overwintering, and foraging habitats, including intermittent or seasonal barriers induced by high water temperatures or low flows; • An abundant food base including terrestrial organisms of riparian origin, aquatic macroinvertebrates, and forage fish; and • Few or no predatory, interbreeding, or competitive non- native species present. An area need not include all of these elements to qualify for designation as critical habitat. 1.2 Proposed Critical Habitat 109. The areas proposed for designation as critical habitat for the bull trout provide one or more of the primary constituent elements described above. All of the proposed areas require special management considerations to ensure their contribution to the conservation of the bull trout. The critical habitat area consists of 18,469 river miles and 532,721 acres of lake and reservoir habitat within 25 units. While the lateral extent of proposed riverine 1- 5 critical habitat is the width of the stream channel defined by its bankfull elevation, the designation of critical habitat is expected to impact inland activity. How far inland the designation's effects extend is a more or less a site specific issue. For example, with regards to land- based activities such as timber sales or grazing practices, it is a matter of site specific physical processes such as sediment transport, the local topography, and the size of the drainage basin. Descriptions of each critical habitat unit are provided in Appendix A. 1.3 Framework and Methodology 110. The primary purpose of this analysis is to estimate the economic impact associated with the designation of critical habitat for bull trout. 8 This information is intended to assist the Secretary in making decisions about whether the benefits of excluding particular areas from the designation outweigh the benefits of including those areas in the designation. 9 In addition, this information allows the Service to address the requirements of Executive Orders 12866 and 13211, the RFA, as amended by the SBREFA. 10 111. This chapter provides the framework for this analysis. First, it defines the economic effects considered in the analysis. Second, it establishes the baseline against which these effects are measured. Third, it describes the measurement of direct compliance costs, which include costs associated with, and generated as a result of, section 7 consultations. Fourth, it identifies potential indirect economic effects of the rule resulting from ( 1) compliance with other parts of the Act potentially triggered by critical habitat, ( 2) compliance with other laws, and ( 3) time delays and regulatory uncertainty. Fifth, it discusses the need for an economic assessment of the benefits of critical habitat designation. Finally, the section concludes by discussing the time frame for the analysis and the general steps followed in the analysis. 1.3.1 Types of Economic Effects Considered 112. This economic analysis considers both the economic efficiency and distributional effects. For the purpose of this analysis, economic efficiency effects generally reflect the " opportunity costs" associated with the commitment of resources required to comply with the Act. For example, if the activities that can take place on a parcel of private land are limited as a result of a designation, and thus the market value of the land reduced, this reduction in value represents one measure of opportunity cost or change in economic efficiency. Similarly, the costs incurred by a Federal Action agency to consult with the Service under section 7 represent economic opportunity costs. 8 This analysis considers the effects of the regulatory action as proposed in the Federal Register on November 29, 2002 ( 67 FR 71236). M6U. S. C. § 1533( b)( 2). 10 Executive Order 12866, " Regulatory Planning and Review," September 30, 1993; Executive Order 13211, " Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use," May 18, 2001; 5 U. S. C. § § 601 etseq; and Pub Law No. 104- 121. 1- 6 113. This analysis also addresses how the impacts are distributed, including an assessment of any local or regional economic impacts and the potential effects on small entities and the energy industry. This information can be used by decision- makers to assess whether the effects might unduly burden a particular group or economic sector. 114. For example, while the designation may have a relatively small impact when measured in terms of changes in economic efficiency, individuals employed in a particular sector of the economy in the geographic area of the designation may experience relatively greater effects. The difference between economic efficiency effects and distributional effects, as well as their application in this analysis, are discussed in greater detail below. Efficiency Effects 115. At the guidance of the OMB and in compliance with Executive Order 12866 " Regulatory Planning and Review," Federal agencies measure changes in economic efficiency in order to understand how society, as a whole, will be affected by a regulatory action. 11 In the context of this regulatory action, these efficiency effects represent the opportunity cost of resources used or benefits foregone by society as a result of critical habitat designation and other co- extensive regulations. 12 Economists generally characterize opportunity costs in terms of changes in producer and consumer surpluses in affected markets. 13 116. In some instances, compliance costs may provide a reasonable approximation for the efficiency effects associated with a regulatory action. For example, a landowner or manager may need to enter into a consultation with the Service to ensure that a particular activity will not adversely modify critical habitat. The effort required for the consultation represents an economic opportunity cost, because the landowner or manager's time and effort would have been spent in an alternative activity had the parcel not been included in the designation. When compliance activity is not expected to significantly affect markets — that is, not result in a shift in the quantity of a good or service provided at a given price, or in the quantity of a good or service demanded given a change in price ~ the measurement of compliance costs can provide a reasonable estimate of the change in economic efficiency. 11 Executive Order 12866, " Regulatory Planning and Review," September 30,1993; U. S. Office of Management and Budget, " Circular A- 4," September 17, 2003. 12 The term " co- extensive" is discussed in greater detail in Section 1.3.3. 13 For additional information on the definition of " surplus" and an explanation of consumer and producer surplus in the context of regulatory analysis, see Gramlich, Edward M, A Guide to Benefit- Cost Analysis ( 2nd Ed.), Prospect Heights, Illinois: Waveland Press, Inc., 1990; and U. S. EPA, Guidelines for Preparing Economic Analyses, EPA 240- R- 00- 003, September 2000, available at http:// yosemite. epa. gov/ ee/ epa/ eed. nsf/ webpages/ Guidelines. html. 1- 7 117. Where a designation is expected to significantly impact a market, it may be necessary to estimate changes in producer and consumer surpluses. For example, a designation that precludes the development of large areas of land may shift the price and quantity of housing supplied in a region. In this case, changes in economic efficiency can be measured by considering changes in producer and consumer surplus in the real estate market. 118. This analysis begins by measuring reasonably foreseeable compliance costs. As noted above, in some cases, compliance costs can provide a reasonable estimate of changes in economic efficiency. However, if the designation is expected to significantly impact markets, the analysis will consider potential changes in consumer and/ or producer surplus in affected markets. Distributional and Regional Economic Effects 119. Measurements of changes in economic efficiency focus on the net impact of the regulation, without consideration for how certain economic sectors or groups of people are affected. Thus, a discussion of efficiency effects alone may miss important distributional considerations concerning groups that may be disproportionately affected. OMB encourages Federal agencies to consider distributional effects separately from efficiency effects. 14 This analysis considers the potential for several types of distributional effects, including impacts on small entities; impacts on energy supply distribution and use; and regional economic impacts. It is important to note that these are fundamentally different measures of economic impact than efficiency effects, and thus cannot be added to or compared with estimates of changes in economic efficiency. Impacts on Small Entities and Energy Supply, Distribution and Use 120. This analysis considers how small entities, including small businesses, organizations, and governments, as defined by the RFA, might be affected by critical habitat designation and other co- extensive regulatory actions. 15 In addition, in response to Executive Order 13211 " Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use," this analysis considers the impacts of critical habitat on the energy industry and its customers. 16 14 U. S. Office of Management and Budget, " Circular A- 4," September 17, 2003. 155U. S. C. § 60\ etseq. 16 Executive Order 13211, " Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use," May 18, 2001. 1- 8 Regional Economic Effects 121. Regional economic impact analysis provides an assessment of the potential localized effects of critical habitat designation and other co- extensive regulations. Specifically, regional economic impact analysis produces a quantitative estimate of the potential magnitude of the initial change in the regional economy resulting from a regulatory action. Regional economic impacts are commonly measured using regional input/ output models. These models rely on multipliers that mathematically represent the relationship between a change in one sector of the economy ( e. g., hydroelectric power generation) and the effect of that change on economic output, income, or employment in other local industries ( e. g., manufacturers relying on the electricity generated). These economic data provide a quantitative estimate of the magnitude of shifts of jobs and revenues in the local economy. 122. The use of regional input/ output models can overstate the long- term impacts of a regulatory change. Most importantly, these models provide a static view of the economy of a region. That is, they measure the initial impact of a regulatory change on an economy but do not consider long- term adjustments that the economy will make in response to this change. For example, these models provide estimates of the number of jobs lost as a result of a regulatory change, but do not consider re- employment of these individuals over time. In addition, the flow of goods and services across the regional boundaries defined in the model may change as a result of the designation, compensating for a potential decrease in economic activity within the region. 123. Despite these and other limitations, in certain circumstances regional economic impact analysis may provide useful information about the scale and scope of localized impacts. It is important to remember that measures of regional economic effects generally reflect shifts in resource use rather than efficiency losses. These types of distributional effects, therefore, should be reported separately from efficiency effects ( i. e., not summed). In addition, measures of regional economic impact cannot be compared with estimates of efficiency effects. 1.3.2 Defining the Baseline 124. The purpose of this analysis is to measure the economic impact of compliance with the protections derived from the designation of critical habitat, including habitat protections that may be " co- extensive" with the listing of the species ( the term " co- extensive" is described in greater detail in the following section). Economic impacts to land use activities may exist in the absence of co- extensive protections. These impacts may result from, for example: • Local zoning laws; • State and natural resource laws; and 1- 9 • Enforceable management plans and BMPs applied by other State and Federal agencies. 125. Economic impacts that result from these types of protections are not included in this assessment; they are considered to be part of the " baseline." Existing laws, regulations, and policies are described in greater detail in Section 2.3 of this analysis. 1.3.3 Direct Compliance Costs 126. The measurement of direct compliance costs focuses on the implementation of section 7 of the Act. This section requires Federal agencies to consult with the Service to ensure that any action authorized, funded, or carried out will not likely jeopardize the continued existence of any endangered or threatened species or result in the destruction or adverse modification of critical habitat. The administrative costs of these consultations, along with the costs of project modifications resulting from these consultations, represent the direct compliance costs of designating critical habitat. 127. This analysis does not differentiate between consultations that result from the listing of the species ( i. e., the jeopardy standard) and consultations that result from the presence of critical habitat ( i. e., the adverse modification standard). Consultations resulting from the listing of the species, or project modifications meant specifically to protect the species as opposed to its habitat, may occur even in the absence of critical habitat. However, in 2001, the U. S. 10th Circuit Court of Appeals instructed the Service to conduct a full analysis of all of the economic impacts of critical habitat designation, regardless of whether those impacts are attributable co- extensively to other causes. 17 Given the similarity in regulatory definitions between the terms " jeopardy" and " adverse modification," in practice it can be difficult to pre- determine the standard that drives a section 7 consultation. Consequently, in an effort to ensure that this economic analysis complies with the instructions of the 10th Circuit as well as to ensure that no costs of the proposed designation are omitted, the potential effects associated with all section 7 impacts in or near proposed critical habitat are fully considered. In doing so, the analysis ensures that any critical habitat impacts that are co- extensive with the listing of the species are not overlooked. 1.3.4 Indirect Costs 128.

The purpose of this report is to identify and analyze the potential economic impacts associated with the designation of critical habitat for the Columbia River and Klamath River Distinct Population Segments ( DPSs) of bull trout ( Salvelinus confluentus), hereafter " bull trout." This report was prepared by Bioeconomics, Inc. of Missoula, Montana, for the U. S. Fish and Wildlife Service's ( the Service) Division of Economics. 2. Section 4( b)( 2) of the Endangered Species Act ( the Act) requires the Service to designate critical habitat on the basis of the best scientific data available, after taking into consideration the economic impact, and any other relevant impact, of specifying any particular area as critical habitat. The Service may exclude areas from critical habitat designation when the benefits of exclusion outweigh the benefits of including the areas within critical habitat, provided the exclusion will not result in extinction of the species. KEY FINDINGS Total costs associated with both listing and critical habitat designation for the bull trout are forecast to be $ 200 million to $ 260 million over the next ten years. Total costs associated with both listing and critical habitat designation for the bull trout within the proposed Klamath Distinct Population Segment are forecast to be $ 5.3 million to $ 7.3 million over the next ten years. Total costs associated with both listing and critical habitat designation for the bull trout within the proposed Columbia Distinct Population Segment are forecast to be $ 195 million to $ 253 million over the next ten years. Federal agencies are expected to bear 70 to 75 percent of these costs; private entities will incur the remaining 25 to 30 percent. Project modification costs account for as much as 63 percent of forecast costs. Administrative cost represent the remaining 37 percent. U. S. Forest Service and Army Corps of Engineer- related activities account for approximately 70 percent of forecast project modification costs. Activities experiencing the greatest costs include timber harvesting, irrigation diversions, and dam and reservoir operations. Dam and reservoir- related consultations, including power facility re- licensing, account for 42 percent of forecast project modification costs ( excluding the cost associated with reduced irrigation diversions). Timber harvest, irrigation diversions, habitat conservation plans, and mining account for 29 percent, 12 percent, eight percent, and three percent of forecast costs, respectively. In terms of river miles, approximately 18 percent of the total forecast costs are associated with one percent of the proposed designation, 25 percent with five percent of the proposed designation, and 45 percent with ten percent of the proposed designation. When expressed in terms of the expected cost per river mile, the two most costly units are the Willamette River Basin ( Unit 4) and the Malheur River Basin ( Unit 13). ES- 1 Framework for the Analysis 3. The primary purpose of this analysis is to estimate the economic impact associated with the designation of critical habitat for the bull trout. This information is intended to assist the Secretary in making decisions about whether the benefits of excluding particular areas from the designation outweigh the benefits of including those areas in the designation. 1 This economic analysis considers the economic efficiency effects that may result from the designation, including habitat protections that may be co- extensive with the listing of the species. It also addresses distribution of impacts, including an assessment of the potential effects on small entities and the energy industry. This information can be used by decision- makers to assess whether the effects of the designation might unduly burden a particular group or economic sector. 4. This analysis focuses on the direct and indirect costs of the rule. However, economic impacts to land use activities can exist in the absence of critical habitat. These impacts may result from, for example, local zoning laws, State and natural resource laws, and enforceable management plans and best management practices ( BMPs) applied by other State and Federal agencies. For example, as discussed in detail in this report, regional management plans, such as the Northwest Forest Plan, PACFISH and INFISH provide significant protection to bull trout and its habitat while imposing significant costs within the region. Economic impacts that result from these types of protections are not included in this assessment as they are considered to be part of the regulatory and policy " baseline." 5. The measurement of direct compliance costs focuses on the implementation of section 7 of the Act. This section requires Federal agencies to consult with the Service to ensure that any action authorized, funded, or carried out will not likely jeopardize the continued existence of any endangered or threatened species or result in the destruction or adverse modification of critical habitat. The administrative costs of these consultations, along with the costs of project modifications resulting from these consultations, represent the direct compliance costs of designating critical habitat. Importantly, this analysis does not differentiate between consultations that result from the listing of the species ( i. e., the jeopardy standard) and consultations that result from the presence of critical habitat ( i. e., the adverse modification standard). 6. The analysis examines activities taking place both within and adjacent to the proposed designation. It estimates impacts based on activities that are " reasonably foreseeable," including, but not limited to, activities that are currently authorized, permitted, or funded, or for which proposed plans are currently available to the public. Accordingly, the analysis bases estimates on activities that are likely to occur within a ten- year time frame, beginning on the day that the current proposed rule became available to the public ( November 30, 2002). The ten- year time frame was chosen for the analysis because, as the time horizon for an economic analysis is expanded, the assumptions on which the projected number of projects and cost impacts associated with those projects becomes increasingly 1 16U. S. C. § 1533( b)( 2). ES- 2 speculative. An exception to the 10 year analysis time horizon used in this analysis is for Federal Energy Regulatory Commission ( FERC) licenses, which are renewed for up to 50 years. Accordingly, this analysis estimates the annualized costs of the expected impacts associated with section 7 bull trout consultations involving FERC re- licensing over a 50 year time horizon. 7. The analysis is based on a wide range of information sources. Numerous individuals were contacted from the Service, as well as from the U. S. Forest Service ( USFS), Federal Highway Administration ( FHWA), Bureau of Land Management ( BLM), Army Corps of Engineers ( ACOE), Bureau of Reclamation ( BOR), Bonneville Power Administration ( BPA), Natural Resources Conservation Service ( NRCS), U. S. Environmental Protection Agency ( EPA), National Oceanic and Atmospheric Administration ( NOAA) and other Federal agencies. The analysis of the hydroelectric facilities and other dam structures in the region also relied in information from the Northwest Power and Conservation Council ( NWPCC), the Pacific Northwest Utility Coordinating Council as well as information from utilities owning dams in bull trout proposed critical habitat ( e. g., Avista Corporation ( Avista), Eugene Water and Electric Board, Pacificorp and Portland General Electric ( PGE)). Native American Tribes ( e. g., Confederated Salish and Kootenai Tribes), State agencies ( e. g., State Departments of Environmental Quality ( DEQ) and State Departments of Transportation ( DOTs)) and industry organizations ( e. g., American Forest Resource Council, American Farm Bureau and Northwest Mining Association) were also contacted, as were numerous individuals in the private sector on topics ranging from irrigation to forestry to bull trout conservation. Census Bureau and other Department of Commerce data was relied on to characterize the regional economy. 8. The bull trout was listed as a threatened species in 1998.2 Since that time, numerous Action agencies have participated in well over 200 formal consultations and thousands of informal consultations involving bull trout. The past consultation record was used as a starting point from which to predict future consultation activity. Action agencies provided additional information on likely changes in future consultation activity following designation of critical habitat. In some cases these agencies saw little change in future consultation levels. For example, FHWA projects are planned for many years in advance and bridge or road- related bull trout consultations are generally quite certain and foreseeable. In some cases ( e. g., mining activity, irrigation diversions) it was determined that the historical consultation record understated the potential level of future consultation activity for the species and adjustments to future predicted consultation levels were made. For dam and reservoir operations, a wide spectrum of information from agency representatives, as well as the actual FERC re- licensing schedules for privately operated hydropower facilities were used to augment historical consultation rates and develop future annual cost estimates associated with bull trout consultations on dam, reservoir and power- related activities. 2 This economic analysis applies only to the Columbia River and Klamath River DPSs of bull trout and is not a rangewide analysis. The rangewide listing of the bull trout occurred in 1999 and critical habitat will be proposed for the remainder of the range at a later date.

Federal agencies are expected to bear approximately 70 to 75 percent of the total costs of this designation. A significant portion of the land adjacent to the proposed designation is Federally owned ( 58 percent), 36 percent is under private ownership and the remainder is comprised of Tribal, State or local interests. Of the Federal lands, the majority is managed by the USFS ( 85 percent) and the BLM ( 12 percent). The remaining 25 to 30 percent of costs are expected to be borne by private entities. Exhibit ES. 2 shows the location of USFS and BLM managed land within the proposed designation. ES- 4 Exhibit ES. 2 ES- 5 10. In some cases, the cost associated with consultation is not borne by the Action agency, but passed onto other parties. For example, while farmers and ranchers do not consult on the operation of Federal irrigation impoundments, irrigators could be impacted by potential reductions in water deliveries to maintain instream flow during dry years. While the unit location of USFS- related water diversions is uncertain, it is likely to occur in the Salmon River ( Unit 16), Clark Fork ( Unit 2), Southwest Idaho River and Clearwater River ( Unit 15) Basins, as these units contain the largest portion of USFS managed lands. 11. Consultations that may involve private entities include those related to timber harvest, grazing, mining and power facility re- licensing. Some of the costs associated with these consultations, however, are expected to be borne directly by or passed onto the Federal government ( e. g., increased logging and yarding costs passed onto the USFS through lower stumpage bids for timber). Most of the forecast project modification costs resulting from designation ( 42 percent) are dam and reservoir related ( excluding USFS water diversions). These costs result from consultations on ACOE and BOR dams and reservoirs, BPA consultations on the FCRPS, and FERC re- licensing consultations. Exhibit ES. 3 illustrates the location of major dams within the proposed critical habitat. The remaining project modification costs are associated with timber harvest ( 29 percent), USFS- related water diversions ( 12 percent), habitat conservation plans ( eight percent), and placer gold mining ( three percent). Grazing, forest management, road and bridge construction and maintenance and other activities each account for less than two percent of forecast project modification costs. Exhibit ES. 4 provides the distribution of total costs by activity. 12. Costs can be expressed in terms of unit or river mile; both of these metrics are useful in describing economic impacts. 3 On a cost per unit basis the largest portion of forecast costs are expected to occur in Unit 4, the Willamette River Basin ( 18 percent). These costs are attributable to fish passage and temperature control projects and annual operating and maintenance and fish study costs at ACOE's facilities in the Upper Willamette River System ( Dexter, Lookout Point, Hills Creek and Blue River Dams). The next most costly unit is Unit 16, the Salmon River Basin ( 12 percent). Because this is the largest unit in terms of river miles and proportion of USFS managed land, and because future USFS activities are expected to generate approximately 70 percent of the consultation activity, this unit bears the greatest number of future bull trout- related consultations. Therefore, the administrative costs account for a large portion of the costs in this unit. Together, these two units account for 30 percent ( approximately $ 8.2 million) of forecast costs. The next three most costly units, Hells Canyon complex ( Unit 12) and the Clark Fork River ( Unit 2) and Malheur River ( Unit 13) Basins, each account for eight percent ( a unit cost range of approximately $ 2.1 million to $ 2.3 million) of forecast costs. In total, these five units account for almost 55 percent of forecast costs ( approximately $ 14.8 million). 3 Twelve of the units also contain more than 500,000 lake acres of critical habitat. These units account for approximately 55 percent of the potential economic impacts associated with the proposed designation ($ 15.4 million). The Clark Fork River Basin ( Unit 2) contains almost 60 percent of the lake acres ( more than 300,000 acres) and accounts for eight percent of the cost ( approximately $ 3 million). Because all 25 units contain river miles, the costs are expressed in terms of dollars per river mile for comparison. ES- 6 ES- 7 ES- 8 13. Project modifications or other restrictions that engender cost and revenue impacts involving commercial enterprises can have a subsequent detrimental effect on other sectors of the local economy, especially when the affected industry is central to the local economy. Industries within a geographic area are interdependent in the sense that they purchase output from other industries and sectors, while also supplying inputs to other businesses. Therefore, direct economic effects on a particular enterprise can affect regional output and employment in multiple industries. The extent to which regional economic impacts are realized depends largely on whether a significant number of projects are stopped or fundamentally altered. For example, impacts to the timber or grazing industries depend on whether required project modifications substantially reduce output within economic sectors below that which would be seen in the absence of the trout consultation. 14. Examination of BOs involving timber harvest and grazing show only small and sporadic reductions in either grazing opportunity or available timber harvest. Therefore, this analysis assumes that regional economic impacts associated with these activities will be unpredictable ( in terms of geographic location and timing) and small in the context of the overall economy of the Columbia River Basin. In the case of agricultural water diversions on Forest Service lands, regional economic impacts are not modeled due to uncertainty about the magnitude and potential location of impacts. 15. Exhibit ES- 5 highlights the relative contributions of each unit to total forecast costs. Exhibit ES- 6 then presents the unit cost by river mile. Considering the cost per river mile, the Willamette River ( Unit 4) and Malheur River ( Unit 13) Basins are the most costly units. Together these two units account for 25 percent of the costs ( approximately $ 7.0 million, annualized) over two percent of the proposed miles of the designation ( 451 miles). Overall, 10 percent of the river miles ( 1,910 miles) in eight units account for approximately 45 percent of the total costs ( approximately $ 12.5 million, annualized). 4 4 In terms of cost per lake acre, the Willamette River Basin is the most expensive unit ( Unit 4), followed by the Northeast Washington River ( Unit 22) and Upper Columbia River ( Unit 21) Basins. These three units account for approximately 25 percent of the cost ($ 6.8 million) and five percent of the river miles ( 1,020 miles) in the proposed designation. ES- 9 tn m W GO 16. Consideration of the regulatory baseline is particularly pertinent in the context of estimating economic costs attributable to section 7 for bull trout. Specifically, existing regulations such as the Federal Power Act ( FPA) and Wilderness Act of 1964, fisheries management directives ( Northwest Forest Plan, INFISH and PACFISH) and the presence of other listed species ( especially anadromous fish) provide for the protection of areas that could contribute to the recovery of bull trout and improve riparian habitat and water quality throughout the proposed designation. Thus, the costs of this designation is limited by the extent to which existing regulations already impose requirements on land use and resource management within the proposed designation. In addition, the cost estimates developed in this report reflect various allocations made throughout the analysis for projects benefitting more than one listed species. Since these allocations are important to the analysis, Exhibit ES. 7 describes how forecasted costs were allocated among bull trout and other listed species. Exhibit ES. 7 ALLOCATION OF ESTIMATED FUTURE PROJECT MODIFICATION COSTS Agency / Project ACOE - Upper Willamette River Dams and Reservoirs BPA - Federal Columbia River Power System FERC - re- licensing hydroelectric facilities USFS activities Allocation NOAA Fisheries and the Service are currently consulting on salmon, steelhead and bull trout in this proposed area. No clear allocation of costs can be made between these species, as most of the projects modifications would be sought under both the NOAA and Service consultations. Therefore, one- third of estimated costs are allocated to each species. This is likely to overstate the cost of bull trout conservation rather than understate it, since the primary driving force behind these project modifications is the salmon. While there is extensive discussion of the relative magnitude of potential bull trout versus salmon mitigation actions, because of the relatively modest project modification costs ( up to $ 400,000 associated with fishery studies) there is no allocation of costs to salmon. The estimation of section 7 bull trout costs associated with FERC re- licensing includes allocation of mitigation costs for specific dams to salmon, as well as to other aquatic species. As a result, a little more than 40 percent of total fishery-related costs are allocated to bull trout, and five percent specifically to bull trout section 7 consultation. While certain costs in the sample of timber consultations were allocated to other listed species ( e. g. grizzlies and cutthroat trout), there is no allocation of costs to anadromous species. Summary of Costs 17. Exhibit ES. 8 provides a detailed summary of the co- extensive costs of designation of critical habitat for the bull trout. These costs are presented on an annualized basis. A map of the watersheds that encompass each unit is provided in Exhibit ES. 9 to assist the reader in understanding the location and distribution of estimated costs. A detailed discussion of the estimated administrative and project modification costs by critical habitat unit is presented in the unit- by- unit summary section following Exhibit ES. 8.

Costs are reported in 2003 dollars. A more detailed presentation of these costs is provided in Appendix F. a Miscellaneous costs ($ 213,000 annually) and the costs associated with development of habitat conservation Dlans ($ 1,090,000 annuallv) have not been allocated to the unit level due to uncertainty as to their location. ES- 13 Exhibit ES- 9 ES- 14 Unit- bv- Unit Summary 18. The following discussion presents a unit- by- unit synopsis of the co- extensive costs of designation of critical habitat for the bull trout. Details on how these cost estimates were developed is provided in Section 4 of this report. 19. From an aggregate perspective, forecast project modification costs are dominated by dam related activities, totaling about 42 percent of all estimated costs. Typical costs include fish passage, changes in operations, habitat protection or restoration, and fishery studies at 36 FERC- licensed hydroelectric facilities and at more than 30 major Federal hydropower, irrigation and flood projects. The second largest category of costs is associated with timber harvest on Federal lands, representing about 29 percent of all estimated costs. These costs include harvest reduction, fishery study and monitoring costs, costs related to roads and culverts, and changes to log yarding systems. The remaining costs are split among a large number of activities including the development of habitat conservation plans, mining, agriculture and irrigation diversions, grazing, bridge construction and maintenance, and general forest management. Accordingly, the primary factor driving the distribution of costs across units is the location of significant dam projects for power, irrigation, and flood control. This factor is highlighted in the following unit- by- unit discussion. The second most important factor is the occurrence of federally- owned acreage within a given unit, particularly the acreage of non- wilderness lands managed by the USFS. This factor drives both timber costs and administrative consultation costs. 20. A significant component of the total estimated cost of this designation are the administrative costs associated with conducting both formal and informal consultations on the species ( approximately 37 to 50 percent of total forecast bull trout- related costs). These costs accrue to the Service as well as to action agencies and the public. In some cases these administrative costs constitute a majority of the estimated costs for a unit, suggesting that there will be many activities consulted on but few resulting project modifications. 21. This discussion is presented on a unit by unit basis. A perspective on how the units compare, in both absolute terms and in terms of cost per river mile of proposed critical habitat, is provided in Exhibits ES- 6 and ES- 7. For purposes of this summary, proposed units with per mile costs ( after adjusting each unit's costs for its respective unoccupied habitat) forecast to be less than half of the proposed designation- wide average are described as having " relatively low costs." Units with per mile costs forecast to be between 50 percent and 200 percent ( i. e., twice) the designation- wide average costs are described as having " relatively moderate costs." Units with per- mile costs forecast to be greater than twice the designation- wide average costs are described as having " relatively high costs." Note that these descriptors are intended as a general guide, and refer to total cost only. Individual economic sectors and entities within a unit may bear disproportionate shares of these costs, as discussed in Section 4. 22. Unit 1: Klamath River Basin - The Klamath River Basin is located in south- central Oregon. Proposed critical habitat within this unit includes 475 km ( 295 mi) of streams and ES- 15 3,775 ha ( 9,327 ac) of lake habitat. The Klamath River Basin Unit is largely contained within Klamath County Oregon. The town of Klamath Falls is the largest community within the county. The Klamath River Basin Unit has a relatively high percentage of proposed critical habitat that is currently either unoccupied or of unknown occupancy ( 72 percent). Approximately 69 percent of the stream miles proposed for designation are within Federal land. 23. The Klamath River Basin Unit is a relatively moderate cost unit. Estimated total annual bull trout- related costs within this unit range between $ 529,000 and $ 733,000. These estimates include $ 425,000 per year in administrative costs. It is estimated that costs associated with consultations on timber harvest and agricultural irrigation withdrawals will constitute the large majority of potential future project modification costs in the unit ( estimated at between 73 percent and 87 percent of total annual project modification costs). These agricultural diversion- related costs are expected to result from reductions in available irrigation water. Other activities are individually estimated to each account for less than $ 15,000 dollars per year in project modification costs. 24. Unit 2: Clark Fork River Basin - The Clark Fork River Basin Unit is the largest unit within the proposed designation. This unit includes most of Western Montana and the Idaho panhandle. This Unit includes the Missoula and Bitterroot River Valleys in Western Montana, the Kalispell- Flathead Lake Region, and the Lake Pend Orielle Region of North Idaho. These areas contain many of the larger towns and communities within Western Montana and North Idaho. Approximately 54 percent of the proposed streams and 33 percent of proposed lakes in Clark Fork Unit are within Federal lands. There is no unoccupied habitat within the proposed Clark Fork Critical Habitat Unit. 25. Forecast total annual costs associated with the bull trout within this unit are between $ 1.3 million and $ 2.2 million. These estimates include $ 800,000 per year in administrative costs. In addition, a number of agencies and activities will incur significant annual project modification costs associated with the bull trout in this unit. Specifically, • Timber harvest activity is expected to generate the largest share of future project modification costs in this unit ($ 270,000 to $ 680,000 per year). These costs include harvest reduction, fishery study and monitoring costs, costs related to road and culverts, and changes to log yarding systems. • Costs associated with forecast project modifications to irrigation diversions within this unit range from zero to $ 280,000. These costs represent potential costs to agricultural producers associated with reductions in available irrigation water. 26. Other significant forecast project modification costs within this unit are associated with mining ( up to $ 100,000 annually, principally involving watershed assessment costs), FERC hydro re- licensing ($ 50,000 to $ 91,000 annually), and FHWA bridge and road work ($ 45,000 per year, generally involving constraints on in- stream work periods). Forecast FERC- related costs are associated with several major hydroelectric facilities within the unit, ES- 16 including Kerr Dam on the Flathead River and Thompson Falls Dam on the Clark Fork. Additionally, bull trout- related modifications on operation of the FCRPS have resulted in changes in operations at Hungry Horse Dam ( a BOR facility on the S. Fork of the Flathead) and Albeni Falls ( an ACOE facility that controls the level of Lake Pend Orielle). Bull trout study costs specific to the Clark Fork Unit and associated with FCRPS consultation are expected to cost up to $ 97,000 annually. 27. Although the proposed Clark Fork River Basin Critical Habitat Unit has significant forecast total annual costs, these costs should be viewed in light of the large size of this proposed unit. In fact, the Clark Fork Unit is forecast to be one of the lowest cost units, when expressed per river mile of habitat proposed for designation. 28. Unit 3: Kootenai River Basin - A short stretch of the Kootenai River lies in the U. S., looping down out of British Columbia. The Kootenai Unit thus comprises only the northwestern corner of Montana, including Libby Dam, and the northeastern tip of the Idaho panhandle. This unit is contained within two counties, Boundary County, Idaho and Lincoln County, Montana. Within this proposed critical habitat unit, approximately 53 percent of the rivers and streams proposed for designation are on Federal land. There is no unoccupied bull trout habitat within this unit. 29. The Kootenai River Unit is a relatively low- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Total forecast annual costs associated with the bull trout within this unit are between $ 328,000 and $ 402,000. Of this amount, the majority, approximately $ 290,000 annually, are forecast administrative costs. In addition, it is estimated that project modification costs within the Kootenai River Unit will total between $ 38,000 and $ 112,000 annually. Costs associated with timber harvest are expected to be the largest category of future project modification costs in this unit ($ 27,000 to $ 69,000 per year, including costs of harvest reduction, fishery study and monitoring costs, costs related to roads and culverts, and changes to log yarding systems). Costs resulting from modifications to agricultural irrigation diversions ( primarily reductions in irrigation withdrawals) could range from zero to $ 28,000. Other activities are individually estimated to each account for less than $ 5,000 per year in project modification costs. Bull trout- related modifications to operations of the FCRPS have resulted in changes in operations at Libby Dam. 30. Unit 4: Willamette River Basin - The Willamette River Basin Unit includes 337 km ( 209 mi) of stream and 1,600 ha ( 3,954 ac) of lake habitat in the McKenzie River and Middle Fork Willamette River subbasins of Western Oregon. The unit is located primarily within Lane County, but also extends into Linn County. The unit contains Eugene, Oregon and surrounding areas. Approximately 46 percent of the proposed waters within this unit are on Federal land and about 23 percent of the waters in the unit are currently either unoccupied by the bull trout or of unknown occupancy. 31. Forecast total annual costs associated with the bull trout within this unit are between $ 4.5 million and $ 4.9 million. Of this amount, approximately $ 125,000 are forecast ES- 17 administrative costs. Thus, most of the costs for this unit are associated with required project modifications. While project modification costs are forecast to be associated with timber harvest activities and agricultural diversions within this unit ( estimated between $ 22,000 and $ 55,000 annually), the vast majority of forecast costs are associated with dam and reservoir operations in the unit. 32. The ACOE is currently in consultation on 13 flood control facilities located in the Upper Willamette River system. Potential future costs of required modifications for bull trout will likely be driven by provisions for temperature control facilities at the Lookout Point, Hills Creek, and Blue River dams, and trap and haul passage at Lookout Point, Hills Creek, and possibly a fish ladder at Dexter Dam. It is estimated that these passage and temperature control modifications and operation at ACOE operated impoundments in the unit will cost between $ 4.3 and $ 4.5 million per year. It is further estimated that annual project modification costs associated with FERC re- licensing of hydroelectric facilities in the unit will cost between $ 70,000 and $ 144,000 annually. These costs are associated with several hydroelectric facilities operated by the City of Eugene: Trail Bridge and Carmen on the McKenzie River, and Blue River Dam. 33. The Willamette River Unit is the highest cost of the proposed units in terms of forecast cost per river mile of habitat proposed for designation ( greater than $ 20,000 per river mile, annually). These costs are associated with dam and reservoir modifications to ACOE projects. However, the ACOE is also consulting with NOAA Fisheries on the impacts of these facilities on chinook salmon and steelhead, these costs might occur even absent the bull trout. 34. Unit 5: Hood River Basin - The Hood River Unit lies entirely within Hood River County, Oregon and contains the communities of Hood River and The Dalles among a number of smaller towns. The Unit includes the mainstem Hood River and three major tributaries: the Clear Branch Hood River, West Fork Hood River, and East Fork Hood River. A relatively high 43 percent of the proposed habitat in the Hood River Unit is currently either unoccupied or of unknown occupancy. Overall, about 48 percent of the waters proposed for designation within this unit are located on Federal lands. 35. The Hood River Unit is a relatively moderate- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit are between $ 328,000 and $ 413,000. Of this amount, a substantial portion are forecast administrative costs ( approximately $ 282,000). The remainder of the forecast costs are associated with required project modifications. Costs associated with FERC re- licensing of hydroelectric facilities ($ 24,000 to $ 67,000) and timber harvest on USFS lands ($ 16,000 to $ 40,000 per year) are expected to be the most significant categories of future project modification costs in the unit. FERC licensed facilities include Powerdale on the Hood River. Agricultural irrigation diversions in the unit could experience up to $ 16,000 in annual project modification costs. Other activities are individually estimated to account for less than $ 5,000 per year in project modification costs. ES- 18 36. Unit 6: Deschutes River Basin - The Deschutes River Basin Unit in central Oregon contains two critical habitat subunits: the lower Deschutes and the upper Deschutes, separated by Big Falls, an impassible barrier on the Deschutes River. The Lower Deschutes critical habitat subunit is in Wasco, Sherman, Jefferson, Deschutes, and Crook Counties. The Upper Deschutes River critical habitat subunit is located in Deschutes, Crook, and Klamath counties. Approximately 801 km ( 498 mi) of stream habitat in the Deschutes River basin is proposed for critical habitat designation. Overall, a relatively high 37 percent of the proposed habitat within the Deschutes River Unit is unoccupied. The entire upper Deschutes River Critical Habitat subunit is currently unoccupied by the species. A relatively low portion ( 35 percent) of the waters proposed for designation within this unit are on Federal land. This unit also has a substantial amount of Tribal land ( 23 percent of proposed waters). 37. The Deschutes River Unit is a relatively low- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. It is forecast that total annual costs associated with the bull trout within this unit will be between $ 431,000 and $ 719,000. A relatively small portion of this amount, approximately $ 102,000 annually, are forecast administrative costs. The vast majority of these costs are associated with required project modifications. Specifically, costs associated with operation of BOR irrigation impoundments ($ 159,000 annually, largely associated with fishery studies), FERC re- licensing of hydroelectric facilities, ($ 106,000 to $ 280,000) and timber harvest on USFS lands ($ 42,000 to $ 105,000 per year resulting from reduced harvest, fishery studies, road and culvert costs, and changes in yarding systems) are expected to be the most significant categories of future project modification costs in this unit. The BOR- related costs are for studies at Crane Prairie and Wickiup Reservoirs on the Upper Deschutes River. Since both of these reservoirs are in the currently unoccupied Upper Deschutes subunit, dam and reservoir modifications are not reasonably foreseeable. Projected FERC re- licensing costs are for bull trout studies and passage at the Pelton- Round Butte Project on the Deschutes River. Agricultural irrigation diversion project modification costs associated with potential reductions in irrigation water availability could range from zero to $ 43,000 annually. Other activities are individually estimated to account for less than $ 15,000 dollars per year in project modification costs. 38. Unit 7: Odell Lake - The Odell Lake Unit in central Oregon lies entirely within the Deschutes National Forest in Deschutes and Klamath counties. This unit is the smallest of the proposed units within the designation. Total proposed critical habitat includes approximately 2,675 ha ( 6,611 ac) of lake habitat and 18.1 km ( 11.3 mi) of streams. There is no unoccupied habitat within this unit. 39. Total annual costs associated with the bull trout within the unit are forecast to be between $ 51,000 and $ 56,000. Of this amount, almost all ( approximately $ 50,000 annually) will be associated with the administrative costs of the consultation process. It is estimated that project modification costs within the Odell Lake Unit will total less than $ 5,000 annually. These project modification costs are forecast to be largely associated with USFS activities. ES- 19 40. Unit 8: John Day River Basin - The John Day River Basin Unit in eastern Oregon includes the North Fork, the Middle Fork, and mainstem portions of the John Day River and their tributary streams in Wheeler, Grant, and Umatilla counties. A total of 1,080 km ( 671 mi) of stream habitat is proposed for designation as critical habitat. Overall, 19 percent of the proposed areas within the John Day River Unit are currently unoccupied by the species. Approximately 54 percent of the waters proposed for designation within the John Day Unit are located on Federal land. 41. The John Day River Unit is a relatively low cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Total annual costs associated with the bull trout within this unit are forecast to be between $ 446,000 and $ 600,000. Of this amount, a large portion, approximately $ 278,000 annually, will be made up of administrative costs. The remainder of the forecast costs are associated with required project modifications. Specifically, project modifications associated with timber harvest on USFS lands ($ 57,000 to $ 143,000 per year from reductions in harvest, fisheries studies, road and culvert costs, and changes in yarding systems) and placer mining on USFS lands ( up to $ 88,000 per year associated with requirements for and limitations on allowed stream crossing activity) are expected to generate the greatest share of project modification costs in this unit. Costs associated with agricultural irrigation diversion reductions could range from zero to $ 58,000 annually. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. The John Day River Basin is one of two units identified in this study as a setting where bull trout related project modifications could have a significant impact on a small placer mining business, the other is the Hells Canyon Complex ( Unit 12). 42. Unit 9: Umatilla- Walla Walla River Basins - The Umatilla and Walla Walla Rivers Unit is located in northeastern Oregon and southeastern Washington. The unit includes 636 km ( 395 mi) of streams extending across portions of Umatilla, Union, and Wallowa counties in Oregon, and Walla Walla and Columbia counties in Washington. Overall, 17 percent of the proposed critical habitat within this unit is currently unoccupied by the species. A relatively low portion ( 32 percent) of the waters proposed for designation within the Umatilla- Walla Walla Unit are located on Federal land. 43. The Umatilla- Walla Walla River Unit is among the lowest cost units, in terms of consultation- related cost per river mile of habitat proposed for designation. It is estimated that total annual costs associated with the bull trout within this unit will be between $ 98,000 and $ 211,000. Of this amount, approximately $ 59,000 annually will be associated with the administrative costs of the consultation process and the remainder with required project modifications. Specifically, fisheries studies associated with FCRPS consultations could cost up to $ 43,000 annually. Project modification associated with timber harvest on USFS lands is expected to be another significant category of future costs in this unit ($ 26,000 to $ 65,000 per year). Agricultural irrigation diversions could experience up to $ 26,000 in annual project modification costs within this unit. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. In addition to the consultation and project modification costs, the Walla Walla Drainage is in ES- 20 the final stages of developing a basin- wide habitat conservation plan to protect bull trout, among other species. The plan has cost approximately $ 4 million to develop, and it is expected an additional $ 1 million will be spent to complete the plan during the next year or two. 44. Unit 10: Grande Ronde River Basin - The Grande Ronde Unit extends across Union, Wallowa, and Umatilla counties in northeastern Oregon, and Asotin, Columbia, and Garfield counties in southeastern Washington. This unit includes the Grande Ronde River from its headwaters to the confluence with the Snake River and a number of its tributaries, the largest being the Wallowa River. Approximately 1,030 km ( 640 mi) of stream habitat in the Grande Ronde River basin is proposed for critical habitat designation. Overall, seven percent of the proposed critical habitat within the Grand Ronde River Unit is currently unoccupied by the species. Approximately 52 percent of the waters proposed for designation within this unit are located on Federal land. 45. The Grand Ronde River Unit is a low- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit will be between $ 467,000 and $ 580,000. Of this amount, the vast majority, approximately $ 417,000 annually, are forecast to be administrative costs. The remainder of the forecast costs are associated with required project modifications. Specifically, fisheries studies within the unit associated with FCRPS consultations could cost up to $ 19,000 annually. Timber harvest on USFS lands is expected to be another significant source of future project modification costs in this unit ($ 34,000 to $ 87,000 per year resulting from reduced harvest, fisheries studies, and road and culvert costs, and changes in yarding systems). Agricultural irrigation diversion costs could be up to $ 35,000. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. 46. Unit 11: Imnaha/ Snake River Basins - The Imnaha/ Snake Unit extends across Wallowa, Baker, and Union counties in northeastern Oregon and Adams and Idaho counties in western Idaho. The unit contains approximately 306 km ( 190 mi) of proposed critical habitat. All of the proposed habitat within the Imnaha- Snake River Unit is currently occupied by the species. Approximately 51 percent of the waters proposed for designation within this unit are located on Federal land. 47. The Imnaha/ Snake River Unit is a moderate- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit are between $ 559,000 and $ 605,000. Of this amount, the large majority are made up of administrative costs ( approximately $ 544,000, annually). The remainder of the forecast costs are associated with required project modifications. Specifically, fishery studies within the unit associated with FCRPS consultations could cost up to $ 18,000 annually. Timber harvest activities on USFS lands are expected to be another significant category of future project modification costs ($ 10,000 to $ 26,000 per year). Agricultural irrigation diversion related project modification costs could range from zero ES- 21 to $ 11,000. Other activities are individually estimated to each account for less than $ 5,000 dollars per year in project modification costs. 48. Unit 12: Hells Canyon Complex - The Hells Canyon Complex Unit encompasses basins in Idaho and Oregon draining into the Snake River and its associated reservoirs, from Hells Canyon Dam upstream to the confluence of the Weiser River. The Hells Canyon Complex unit includes a total of approximately 1,000 km ( 621 mi) of streams proposed as critical habitat. A relatively high portion ( about 48 percent) of the proposed critical habitat within the Hells Canyon Complex Unit is currently unoccupied by the species. Approximately 47 percent of the waters proposed for designation within this unit are located on Federal land. 49. The Hells Canyon Complex Unit is a relatively moderate- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. It is forecast that total annual costs associated with the bull trout within this unit will be between $ 1.9 million and $ 2.3 million. Of this amount, a majority are expected to be made up of administrative costs ( approximately $ 1.4 million, annually). In addition, significant categories of forecast project modification costs within this unit are associated with timber harvest on USFS lands ($ 92,000 to $ 233,000 per year resulting from reduced harvest, fishery studies, road and culvert costs, and changes in yarding systems), placer mining on USFS land ($ 69,000 associated with requirements for and limitations on allowed stream crossing activity), FERC hydroelectric re- licensing ($ 111,000 to $ 259,000), and BOR reservoir activities ($ 192,000 annually, primarily for study related costs). The BOR reservoirs in the unit include Phillips Reservoir and Thief Valley Reservoir; projected costs are for bull trout related studies. Major FERC- licensed hydroelectric facilities in the unit include Hells Canyon, Brownlee and Oxbow. Agricultural irrigation diversions could experience up to $ 95,000 in annual project modification costs within this unit. Other activities are individually estimated to each account for less than 20,000 dollars per year in project modification costs. The Hells Canyon complex is one of two units identified in this study as a setting where bull trout related project modifications could have a significant impact on a small placer mining business, the other is the John Day River Basin ( Unit 8). 50. Unit 13: Malheur River Basin - The Malheur Unit is in the Malheur River Basin in eastern Oregon, in Grant, Baker, Harney, and Malheur counties. A total of 389 km ( 241 mi) of streams and two reservoirs are proposed for critical habitat. About 25 percent of the proposed critical habitat within the Malheur River Unit is currently unoccupied by the species. Approximately 63 percent of the waters proposed for designation within the Malheur River Unit are located on Federal land. 51. The Malheur River Unit is the second highest cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit are between $ 2.0 million and $ 2.1 million. Project modification costs make up a small portion of these costs, between $ 179,000 and $ 268,000 annually. The rest of the forecast costs are associated with administrative requirements. Major categories of forecast project modification costs within this unit are associated with ES- 22 timber harvest on USFS lands ($ 33,000 to $ 83,000 per year) and BOR reservoir activities ($ 133,000 annually). The BOR costs are for research as well as trap and haul fish passage that is ongoing at Beulah Reservoir on the Malheur River, and estimated research costs at Warm Springs Reservoir, which is currently unoccupied by bull trout. Possible reductions in agricultural irrigation diversions could cost from zero to $ 34,000 annually . Other activities are individually estimated to each account for less than $ 5,000 per year in project modification costs. 52. Unit 14: Coeur d'Alene Lake Basin - The Coeur d'Alene Lake Basin Unit in Idaho is broken into two subunits. The Coeur d'Alene Lake subunit lies within Kootenai, Shoshone, Benewah and Bonner counties. The St. Joe River subunit includes streams in Shoshone, Benewah, and Latah counties, Idaho. Thirty stream reaches or tributaries ( 677 km ( 421 mi)) and lakes comprising 12,727 ha ( 31,450 ac) of surface area are proposed as critical habitat within this unit. Of this, a relatively high portion ( 46 percent) is currently unoccupied by the species. Approximately 58 percent of the waters proposed for designation within this Unit are located on Federal land. 53. The Coeur d'Alene Lake Unit is relatively low cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit are between $ 429,000 and $ 693,000. A large share of this amount, approximately $ 287,000 annually, is forecast to be made up of administrative costs. In addition, major categories of forecast project modification costs within the unit are associated with timber harvest on USFS lands ($ 97,000 to $ 245,000 per year resulting from reduced harvest, fishery studies, road and culvert costs, and changes in yarding systems), and FHWA bridge and road work ($ 23,000 associated with limitations on in- stream work periods). Modifications to agricultural irrigation diversions could result in costs from zero to $ 100,000. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. 54. Unit 15: Clearwater River Basin - The Clearwater River Unit includes 3,063 km ( 1,904 mi) of streams and 6,722 ha ( 16,611 ac) of lakes proposed as critical habitat for bull trout in north- central Idaho. This large unit extends from the Snake River confluence at Lewiston on the west to headwaters in the Bitterroot Mountains along the Idaho/ Montana border on the east. About 13 percent of the proposed critical habitat within the Clearwater River Unit is currently unoccupied by the species. Approximately 78 percent of the waters proposed for designation within the Unit are located on Federal land. 55. Total forecast costs associated with consultation on bull trout within this unit are between $ 1.0 million and $ 1.7 million annually. Of this amount, approximately $ 572,000 is associated with administrative costs. In addition, major categories of forecast project modification costs within this unit are associated with timber harvest on USFS lands ($ 252,000 to $ 635,000 per year resulting from reduced harvest, fishery studies, road and culvert costs and changes in yarding systems), recreational suction mining on USFS land ($ 115,000 associated with reduced availability of stream access due to seasonal closures), highway bridge and road work ($ 25,000), and USFS management activities ($ 35,000 ES- 23 annually). Agricultural irrigation diversion project modification costs could range from zero up to $ 259,000 annually. These costs may result from reductions in irrigation deliveries. Other activities are individually estimated to each account for less than $ 15,000 dollars per year in project modification costs. 56. Although the proposed Clearwater River Basin Critical Habitat Unit is forecast to experience significant costs associated with the bull trout, these costs should be viewed in light of the large size of the proposed unit. In fact, the Clearwater Unit is one of the lowest cost of the proposed units, in terms of forecast costs per river mile of habitat proposed for designation. 57. Unit 16: Salmon River Basin - The Salmon River basin is a geographically large unit that extends across central Idaho from the Snake River to the Montana border. The critical habitat unit includes 7,688 km ( 4,777 mi) of streams extending across portions of Adams, Blaine, Custer, Idaho, Lemhi, Nez Perce, and Valley counties in Idaho. About six percent of the proposed critical habitat within the Salmon River Unit is currently unoccupied by the species. Approximately 86 percent of the waters proposed for designation within the Unit are located on Federal land. 58. Forecast total annual costs associated with the bull trout within this unit are between $ 2.1 million and $ 3.3 million. Of this amount, approximately $ 1.3 million is associated with administrative costs, with the rest made up of project modification costs. Major categories of forecast project modification costs are associated with timber harvest on USFS lands ($ 465,000 to $ 1.2 million per year resulting from reduced harvest, fishery studies, road and culvert costs and changes in yarding systems), highway bridge and road work ($ 57,000), and USFS general forest management activities ($ 65,000 annually). The cost of modifications to agricultural irrigation water deliveries could range from zero up to $ 479,000 annually. Costs associated with mining activities at Hecla Mining Company's Grouse Creek and Thompson Creek mines are estimated at $ 132,000 annually. Other activities are individually estimated to each account for less than $ 25,000 dollars per year in project modification costs. 59. Although the proposed Salmon River Basin Critical Habitat Unit has significant forecast costs associated with the bull trout, these costs should be viewed in light of the large size of the proposed unit. In fact, the Salmon River Unit is also one of the lowest cost of the proposed units, in terms of forecast costs per river mile of habitat proposed for designation. 60. Unit 17: Southwest Idaho River Basins - The Southwest Idaho Unit includes a total of approximately 2,792 km ( 1,735 mi) of streams in the Boise, Payette, and Weiser River basins. A number of southern Idaho counties are wholly or partially within this unit, including Ada, Adams, Boise, Camas, Canyon, Elmore, Gem, Payette, Valley, and Washington counties. The counties within the southern Idaho unit include both a significant portion of productive agricultural land as well as the largest population center in the state ( the Boise Valley). About 24 percent of the proposed critical habitat within the Southwest ES- 24 Idaho Unit is currently unoccupied by the species. Approximately 78 percent of the proposed streams and 66 percent of proposed lakes and reservoirs within the Southwest Idaho River Basins Unit are located on Federal land. 61. The Southwest Idaho River Basins Unit is a relatively low- cost unit, in terms of forecast costs per river mile of habitat proposed for designation. Forecast total annual costs associated with the bull trout within this unit are between $ 1.0 million and $ 1.9 million. Total administrative costs are forecast to be a relatively small portion of this total ($ 328,000 annually). The remainder of the forecast costs are expected to result from forecast project modifications. Specifically, project modification costs within this unit are forecast to be associated with timber harvest on USFS lands ($ 309,000 to $ 781,000 per year resulting from reduced harvest, fishery studies, road and culvert costs and changes in yarding systems) and BOR reservoir activities ($ 263,000 annually). Major BOR reservoirs in this unit include Anderson Ranch and Arrowrock Reservoirs on the Boise River, Cascade Reservoir on the North Fork Payette, and Deadwood Reservoir on the Payette River. Forecast project modification costs include bull trout life- cycle studies and monitoring at all the reservoirs, and trap and haul passage around the Boise River reservoirs. Costs associated with FERC relicensing at the Lucky Peak facility on the Boise River, and power facilities at the Cascade impoundment, are expected to cost between $ 31,000 and $ 58,000 annually. Modifications to agricultural irrigation diversions could range from zero to $ 318,000 annually. These costs could potentially be associated with reductions in irrigation water withdrawals. Other activities are individually estimated to each account for less than $ 30,000 dollars per year in project modification costs. 62. Unit 18: Little Lost River Basin - The Little Lost River Unit is within Butte, Custer, and Lemhi counties in east- central Idaho. Approximately 184.6 km ( 115.4 mi) of stream habitat in the Little Lost River Basin is proposed for critical habitat designation. About eight percent of the proposed critical habitat within the Little Lost River Unit is currently unoccupied by the species. Approximately 76 percent of the proposed streams within the Little Lost River Basin Unit are located on Federal land. 63. The Little Lost River Unit is forecast to be a relatively inexpensive unit compared to others in the designation, and is a moderate- cost unit in terms of forecast costs per river mile of habitat proposed for designation. It is estimated that total annual costs associated with the bull trout within this unit will be between $ 150,000 and $ 176,000. Of this amount, a large share, approximately $ 136,000 annually, is forecast to be comprised of administrative costs, with the remainder made up of project modification costs. The largest category of project modification costs within this unit is forecast to be associated with timber harvest on USFS lands ($ 10,000 to $ 24,000 per year). Project modifications to agricultural irrigation diversions could result in costs from zero to $ 10,000 annually. Other activities are individually estimated to each account for less than $ 5,000 dollars per year in project modification costs. 64. Unit 19: Lower Columbia River Basin - The Lower Columbia Unit consists of portions of the Lewis, White Salmon, and Klickitat Rivers, and associated tributaries in ES- 25 southwestern and south- central Washington. The unit extends across Clark, Cowlitz, Klickitat, Skamania, and Yakima counties. Approximately 340 km ( 210 mi) of streams and three reservoirs covering 5,054 ha ( 12,488 ac) are proposed for critical habitat designation. About 20 percent of the proposed critical habitat within the Lower Columbia River Unit is currently unoccupied by the species. A low portion ( 18 percent) of the proposed streams and 29 percent of the proposed lakes and reservoirs within the Lower Columbia River Basin Unit are located on Federal land. 65. When forecast total costs for this unit are viewed in light of its size, the Lower Columbia River Basins Unit is a moderate- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. It is estimated that total annual costs associated with the bull trout within the unit will be between $ 385,000 to $ 494,000. Total administrative costs associated with the consultation process are estimated to be a relatively large fraction of these costs ($ 304,000 annually). In addition, project modification costs are forecast to be associated with FERC hydroelectric facility re- licensing activities ($ 67,000 to $ 153,000 annually). These FERC re- licensing costs are for the significant hydroelectric developments on the Lewis River, including Yale, Merwin, Swift No. 1, and Swift No. 2. These costs are projected to include study costs, trap and haul passage, and habitat acquisition. Swift No, 2 is one of two hydroelectric projects identified in this study where bull trout- related project modifications could have a significant impact on a small business; the other is Box Canyon in the Northeast Washington River Basin ( Unit 22). Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. 66. Unit 20: Middle Columbia River Basin - The Middle Columbia River unit encompasses the entire Yakima River basin located in south central Washington, draining approximately 15,900 square km ( 6,155 square mi). The basin occupies most of Yakima and Kittitas counties, about half of Benton County, and a small portion of Klickitat County. Approximately 846 km ( 529 mi) of stream habitat and 6,066 ha ( 14,986 ac) of lake and reservoir surface area are proposed as critical habitat within this unit. About 13 percent of the proposed critical habitat within the Middle Columbia River Unit is currently unoccupied by the species. Approximately 44 percent of the waters proposed for designation within the Middle Columbia River Basin Unit are located on Federal land. 67. The Middle Columbia River Unit is a relatively low- cost unit in terms of cost per stream mile. Forecast costs associated with the bull trout within this unit are between $ 391,000 and $ 494,000 annually. Of this amount, a very small portion, approximately $ 50,000 annually, will be associated with the administrative costs of the consultation process, while the remainder will be associated with project modifications. While there are projected to be project modification costs associated with timber harvest activities ( through consultation with the USFS; estimated to be between $ 36,000 and $ 91,000 annually), the majority of forecast costs for this unit are associated with dam and reservoir operations. The BOR operates a system of five dams in this basin ( Cle Elum Lake, Kachess Lake, Keechelus Lake, Tieton Dam, and Bumping Lake) which provide power and irrigation for this agriculturally important region. It is estimated that project modification costs ( periodic trap- ES- 26 and- haul passage to allow genetic interchange between isolated bull trout populations) at the BOR operated impoundments in the unit will cost approximately $ 290,000 per year. Other activities are individually estimated to account for a small portion of forecast annual project modification costs. 68. TheMiddle Columbia River Unit is a relatively low- cost unit in terms of cost per stream mile. 69. Unit 21: Upper Columbia River Basin - The Upper Columbia River Basin includes three subunits in central and northern Washington: the Wenatchee River subunit in Chelan County; the Entiat River subunit in Chelan County; and the Methow River subunit in Okanogan County. A total of 909.7 km ( 565.4 mi) of streams and 1,010 ha ( 2,497 ac) of lake surface area are proposed for critical habitat. About nine percent of the proposed critical habitat within the Upper Columbia River Unit is currently unoccupied by the species. Approximately 58 percent of the proposed streams and 41 percent of the proposed lakes and reservoirs within the Upper Columbia River Basin Unit are located on Federal land. 70. The Upper Columbia River Basins Unit is a low- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. Forecast costs associated with the bull trout within this unit are between $ 196,000 to $ 505,000 annually. Total administrative costs associated with the consultation process are estimated to be $ 122,000, with the remainder of the forecast costs made up of project modification requirements. Major categories of forecast project modification costs within this unit are associated with FCRPS fisheries studies ( zero to $ 155,000 per year), and USFS timber harvest activities ($ 57,000 to $ 144,000 annually resulting from reduced harvest, fishery studies, road and culvert costs and changes in yarding systems). The FCRPS fisheries studies are for bull trout radio telemetry, snorkel and general monitoring study costs in the Entiat, Methow, and Wenatchee Rivers. In addition, modifications to agricultural irrigation diversions could result in costs from zero to $ 59,000 annually. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. 71. Unit 22: Northeast Washington River Basins - The Northeast Washington unit includes bull trout above Chief Joseph Dam on the Columbia River. A total of 373.1 km ( 231.9 mi) of streams and 1,166 ha ( 2,880 ac) of lake surface area are proposed as critical habitat within this unit. A high proportion ( 54 percent) of the proposed critical habitat within the Northeast Washington River Basins Unit is currently unoccupied by the species, and approximately 58 percent of the proposed streams and reservoirs within this unit are located on Federal land. 72. The Northeast Washington River Basins Unit is forecast to be a relatively high- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. Forecast costs associated with the bull trout within this unit are between $ 965,000 to $ 1.4 million annually. Total annual administrative costs are estimated to be a large share of these costs ($ 676,000), with the remainder associated with project modifications. A major category of ES- 27 annual project modification costs within this unit involves FERC hydroelectric facility re-licensing activities ( up to $ 540,000 annually). The estimated FERC re- licensing costs are related to two major hydroelectric facilities on the Pend Orielle River: Box Canyon and Boundary. The Box Canyon re- licensing terms are currently in continuing settlement negotiations, and likely costs specific to this facility are not currently available. However, a recent FERC environmental impact statement ( EIS) estimates that the present value of bull trout related project modifications ( including habitat acquisition) could total upwards of $ 60 million for this relatively small ( 60 MW) facility. Box Canyon is one of two hydroelectric projects identified in this study where bull trout- related project modifications could have a significant impact on a small business; the other is Swift No. 2 in the Lower Columbia River Basin ( Unit 19). Modifications to agricultural irrigation diversions could impose costs from zero to $ 46,000 annually. Other activities are individually estimated to each account for less than $ 10,000 dollars per year in project modification costs. 73. Unit 23: Snake River Basin in Washington - The Snake River Washington Unit includes two critical habitat subunits located in southeast Washington: the Tucannon River subunit located in Columbia and Garfield counties, and the Asotin Creek subunit within Garfield and Asotin counties. A total of 326 km ( 203 mi) of stream reaches are proposed as critical habitat within this unit. About 23 percent of the proposed critical habitat within the Snake River Basin in Washington Unit is currently unoccupied by the species. Approximately 52 percent of the proposed streams within the Snake River Basin Unit are located on Federal land. 74. The Snake River Basin Unit is a relatively low- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. Forecast costs associated with the bull trout within the unit will be between $ 230,000 to $ 287,000. Total annual administrative costs associated with the bull trout are estimated to be a large portion of this total ($ 201,000). The major category of project modification costs within this unit is forecast to be associated with USFS timber harvest activities ($ 21,000 to $ 53,000 annually). Agricultural irrigation diversions could see up to $ 22,000 in annual project modification costs within this unit. Other activities are estimated to each account for less than $ 5,000 dollars per year in project modification costs. 75. Unit 24: Columbia River - This unit is located in the states of Oregon and Washington and includes Clatsop, Columbia, Multnomah, Hood River, Wasco, Sherman, Gilliam, Morrow, and Umatilla counties in Oregon and Pacific, Wahkiakum, Cowlitz, Clark, Skamania, Klickitat, Benton, Walla Walla, Franklin, Yakima, Grant, Kittitas, Chelan, Douglas, and Okanogan counties in Washington. All of this stretch of the Columbia River is currently considered occupied by the bull trout. A relatively low share of the land adjacent to the river in this unit is made up of Federally managed lands ( approximately 39 percent). 76. The Columbia River Unit is a relatively low- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. Forecast total costs associated with the bull trout within this unit will be between $ 243,000 to $ 504,000 annually. Total annual ES- 28 administrative costs associated with this unit are relatively low ($ 50,000). The major category of annual project modification costs within the unit are forecast to be associated FERC hydroelectric facility re- licensing activities ( up to $ 362,000 annually). Major FERC-licensed hydroelectric projects on the mainstem Columbia River include Priest Rapids, Rocky Reach, and Wells. These very large facilities are operated by PUD's. Other activities are individually forecast to account for less than $ 15,000 dollars per year in project modification costs. 77. Unit 25: Snake River - The lower Snake River is located in Washington ( Franklin, Walla Walla, Columbia, Whitman, and Asotin counties) from its mouth to the confluence with the Clearwater River at the cities of Clarkston, Washington and Lewiston, Idaho. The Snake River forms the border between Washington and Idaho from Clarkston/ Lewiston upstream to the Oregon border. The Snake River forms the boundary between Idaho and Oregon from that point upstream to the limit of this critical habitat unit. This portion of the Snake River is within Nez Perce, Idaho, Adams, and Washington counties in Idaho, and Wallowa, Baker, and Malheur counties in Oregon. About 20 percent of the proposed critical habitat within the Snake River Unit is currently unoccupied by the species. Approximately 50 percent of the habitat proposed for designation within the Snake River Unit is located on Federal land. 78. The Snake River Unit is a relatively low- cost unit, in terms of forecast cost per river mile of habitat proposed for designation. Forecast costs associated with the bull trout within this unit are approximately $ 135,000. Administrative costs associated with the consultation process are estimated to be nearly all of that amount, or $ 125,000 annually. Small Business Effects 79. Under the Regulatory Flexibility Act ( RFA) ( as amended by the Small Business Regulatory Enforcement Fairness Act ( SBREFA) of 1996), whenever a Federal agency is required to publish a notice of rulemaking for any proposed or final rule, it must prepare and make available for public comment a regulatory flexibility analysis that describes the effect of the rule on small entities ( i. e., small businesses, small organizations, and small government jurisdictions). The following summarizes the potential effects of critical habitat designation on small entities: Reductions in contractual USFS water deliveries could significantly impact five ranching/ farming operations annually. However, the location of the reduction in water deliveries within the critical habitat designation is uncertain. Small hydroelectric producers in Washington, Oregon, Idaho and Montana could be affected by project modification costs at the time of facility re- licensing. Specifically, the resulting project modifications could have a significant economic impact on the financial operations of Cowlitz County public utility district ( PUD) ( Unit 19 - Lower Columbia River) and Pend Orielle County PUD ( Unit 22 - Northeast Washington River). ES- 29 • Section 7- related costs associated with instream work is expected to affect approximately 15 placer mines annually in the John Day River Basin ( Unit 8) and Hells Canyon Complex ( Unit 12). While the financial characteristics of these mining operations are unknown, this analysis assumes the economic effect will be significant for those operations that are impacted. Energy Industry Impacts 80. Pursuant to Executive Order No. 13211, Federal agencies are required to submit a summary of the potential effects of regulatory actions on the supply, distribution and use of energy. Two criteria are relevant to this analysis: 1) reductions in electricity production in excess of 1 billion kilowatt- hours per year or in excess of 500 megawatts ( MWs) of installed capacity and 2) increases in the cost of energy production in excess of one percent. The constraints placed on energy production within the region from compliance with bull trout section 7 consultations will not result in significant decreases in production or increases in energy costs within the region. Changes From Draft Economic Analysis 81. Information supplied though public comments to the Draft Economic Analysis along with additional information from Action agency and Service personnel on issues raised through public comment led to several changes to the analysis. This Final Economic Analysis contains the following significant changes from the draft report. 1) Additional information on Habitat Conservation Plans ( HCPs) currently under development within the proposed designation has been incorporated. Additional costs on the order of one million dollars annually have been added to the estimated costs reported. 2) The BOR supplied extensive comments on current and potential costs associated with consultation on its impoundments. Costs associated with potential project modifications to Yakima Drainage dams ( as well as for other BOR impoundments within the proposed designation) have been reduced in response to the new BOR information. 3) Information from Hecla Mining Company identified additional consultation- related costs for the Hecla Grouse Creek and Thompson Creek mines. These costs have been included in the section 4 discussion of USFS mining activity. 4) Information from USFS personnel from the Wallowa/ Whitman National Forest identified impacts associated with limitations on in- stream work windows for placer mining operations as baseline State of Oregon regulations that are independent of bull trout section 7 consultation. Estimated impacts to Oregon placer mining have been adjusted accordingly. ES- 30 5) Additionally, corrections to minor errors within the report, not impacting final cost estimates, have been made in response to public comments. Caveats to Economic Analysis 82. Exhibit ES. 10 presents the key assumptions of this economic analysis, as well as the potential direction and relative scale of bias introduced by the assumptions. 83. These caveats below describe factors that introduce uncertainty into the results of this analysis. ES. 10 CAVEATS TO THE ECONOMIC ANALYSIS Key Assumption Projected USFS timber harvest activity is based on recent regional history and ignores the declining long- term trend of the industry. USFS water diversion reductions occur annually and representative water costs reflect the high- end of water lease rates in Washington. Cost of USFS water diversion reductions and timber harvest project modifications are distributed across the units in proportion to USFS non- wilderness acreage. While this may have no effect on the total cost estimate, it may have an effect on the unit cost estimate. Total costs of providing technical assistance is expected to be small relative to other economic impacts; therefore, this analysis does not quantify the instances and costs of technical assistance efforts. Project modifications incorporating measures suggested by the Service and voluntarily agreed to by the applicant during the informal consultation process in order to minimize impact to the bull trout and/ or its habitat are not quantified in this analysis. Amortization of fishery- related capital investments are based on the life of the project rather than a shorter revenue recovery period. Changes in hydroelectric power revenues attributable to reductions in operational flexibility at Libby and Hungry Horse dams is not quantified Most of the project modification costs will either be borne directly by or passed onto the Federal government. The FPA, the Pacific Northwest Electric Power Planning and Conservation Act, and fisheries management directives ( Northwest Forest Plan, INFISH and PACFISH) provide baseline protection. Project modification costs allocated between bull trout and other listed species. Limited consultation with the NRCS is anticipated and based on a the record of past formal and informal consultation activity on the bull trout Effect on Cost Estimate + + +/- - - - - +/- +/- +/- - -: This assumption may result in an underestimate of real costs. + : This assumption may result in an overestimate of real costs. +/-: This assumption has an unknown effect on estimates. ES- 31 Estimated Cost of the Final Designation 84. The analysis contained in this report is consistent with the designation as described in the proposed rule; 5 however, the Service is expected to exclude some proposed areas of habitat to arrive at a final designation. The purpose of this section is to detail the expected changes to the proposed designation and show the implication of these changes on estimated consultation and project modification costs. 85. Exhibit ES. ll compares the spatial extent of the proposed and expected final designations for bull trout critical habitat for both river and stream miles and lake and reservoir acres. Overall, 1,925 miles of rivers and streams and approximately 55,000 acres of lakes and reservoirs are expected to be excluded from critical habitat in the final designation. The greatest reductions in critical habitat stream miles are expected to occur in the Deschutes River Unit ( 60.5 percent reduction), Hood River Unit ( 33.2 percent), Southwest Idaho River Basins Unit ( 32.8 percent), and the Hells Canyon Complex Unit ( 21.3 percent). Most of the reductions in lake and reservoir critical habitat acres are expected to occur in the Deschutes River, Southwest Idaho River Basins and Malheur River Units, all with more than a 70 percent reduction in designated lake and reservoir critical habitat compared to the original proposed designation.

As noted, the costs reported in the body of this report are consistent with the proposed designation. Expected changes to the proposed designation and the impact of these exclusions on costs are summarized in Exhibit ES. 12, where estimates of annual section 7- related consultation costs for both the proposed and expected final bull trout critical habitat designations are shown. The expected changes to the final designation impacts estimated costs in two ways. 87. First, where future consultation and project modification costs were estimated for dams and reservoirs located within stream reaches that are expected to be excluded from the final critical habitat designation, the costs associated with these anticipated consultations are removed. Three critical habitat units have dams and reservoirs located on waters expected to be excluded in the final designation. The previously quantified costs associated with consultations on Lucky Peak and Cascade Dams and Reservoirs, and Warm Springs, Crane Prairie, and Wickiup Reservoirs have therefore been removed from the forecast total costs associated with the final critical habitat designation. Costs associated with consultations on Lucky Peak and Cascade Dams and Reservoirs have been removed from estimates for the Southwest Idaho River Basins Units, costs associated with consultation on Warm Springs Reservoir have been removed from estimates for the Malheur River Unit, and costs associated with consultations on Crane Prairie and Wickiup Reservoirs have been removed from estimates for the Deschutes River Unit. 88. Second, because the Service is expected to exclude areas of unknown occupancy from the final designation, the spatial extent of unoccupied habitat in each critical habitat ES- 33 unit is adjusted to reflect the expected final designation ( see Appendix F, Exhibit F. 11), and the forecast costs of the expected final designation reflect these changes. 89. Exhibit ES. 12 presents a summary of the annualized forecast total costs, by unit, likely to be associated with the final critical habitat designation over the next ten years. Overall, the removal of waters from the proposed to the expected final bull trout designation is expected to lower forecast section 7- related consultation and project modification costs by approximately $ 18 to $ 24 million over the next ten years ( nine percent). In six units where no changes in the proposed designation were made, there is no change in forecast costs. As a percentage of unit costs, the greatest reduction in forecast costs resulting from the exclusions is expected to occur in the Deschutes River Basin Unit, where forecast costs of the expected final designation are 43 to 55 percent of the costs originally forecast for the proposed designation. 90. The economic impacts associated with the final designation, discounted to present value using a rate of seven percent, are forecast to range from approximately $ 180 to $ 245 million over the next ten years, or $ 18.0 to $ 24.5 million annually. Total costs associated with the final designation for the Klamath Distinct Population Segment of bull trout are forecast to range from approximately $ 5 million to $ 7 million over the next ten years ($ 0.5 to 0.7 million annually), while costs associated with the final designation for the Columbia Distinct Population Segment of bull trout are forecast to range from approximately $ 175 million $ 235 million ($ 17.5 to $ 23.5 million annually). 91. These costs will be incurred primarily by Federal agencies responsible for section 7 consultations ( approximately 65 percent of forecast costs) and the Service ( approximately five to ten percent of forecast costs); private entities will incur the remaining 25 to 30 percent. Project modification costs account for as much as 50 to 60 percent of forecast costs, and administrative costs the remaining 40 to 50 percent. Dam and reservoir- related consultations, including power facility re- licensing, account for approximately 42 percent of forecast project modification costs ( excluding the cost associated with reduced irrigation diversions). Timber harvest, irrigation diversions, habitat conservation plans, and mining account for 20 percent, 12 percent, nine percent, and three percent of forecast project modification costs, respectively. 92. The main text of the report discusses impacts to small businesses expected under the rulemaking as proposed. Impacts to small businesses are primarily related to potential reductions in USFS water deliveries to farmers/ ranchers, project modifications triggered during hydroelectric facility re- licensing, and costs associated with activity restrictions for placer mining. Under the final designation, the reduction in small business impacts would parallel the extent to which these activities occur in habitat removed from the final designation and losses related to these activities reduced.

ES- 36 INTRODUCTION AND BACKGROUND SECTION 1 93. In November 2002, the Service proposed to designate critical habitat for the Columbia River and Klamath River DPSs of bull trout ( Salvelinus confluentus), hereafter " bull trout." 6 The purpose of this report is to identify and analyze potential economic impacts associated with the proposed critical habitat designation. This report was prepared by Bioeconomics, Inc. of Missoula, Montana. 94. Section 4( b)( 2) of the Act requires the Service to designate critical habitat on the basis of the best scientific data available, after taking into consideration the economic impact, and any other relevant impact, of specifying any particular area as critical habitat. The Service may exclude areas from critical habitat designation when the benefits of exclusion outweigh the benefits of including the areas within critical habitat, provided the exclusion will not result in extinction of the species. 95. Under the listing of a species, section 7( a)( 2) of the Act requires Federal agencies to consult with the Service in order to ensure that activities they fund, authorize, permit, or carry out are not likely to jeopardize the continued existence of the species. The Service defines jeopardy as any action that would appreciably reduce the likelihood of both the survival and recovery of the species. For designated critical habitat, section 7( a)( 2) also requires Federal agencies to consult with the Service to ensure that activities they fund, authorize, permit, or carry out do not result in destruction or adverse modification of critical habitat. Adverse modification of critical habitat is currently construed as any direct or indirect alteration that appreciably diminishes the value of critical habitat for conservation of a listed species. 6 On January 26,2001, the Alliance for the Wild Rockies, Inc. and Friends of the Wild Swan, Inc. filed a lawsuit in the U. S. District Court of Oregon challenging the Service's failure to designate critical habitat for bull trout. The Service entered into a settlement agreement on January 14, 2002, which stipulated that the Service would make critical habitat determinations for five populations of bull trout ( Civil Case No: CV 01- 127- JO). The Service has proposed critical habitat for the Columbia River and Klamath River populations, which are the subject of this analysis. 1- 1 1.1 Description of Species and Habitat7 96. Bull trout { Salvelinus confluentus, family Salmonidae) is a char native to waters of western North America. The historic range of bull trout includes major river basins in the Pacific Northwest from about 41° north to 60° north latitude, extending south to the McCloud River in northern California and the Jarbidge River in Nevada, and north to the headwaters of the Yukon River in Northwest Territories, Canada. To the west, bull trout range includes Puget Sound, various coastal rivers of British Columbia, Canada, and southeast Alaska. Bull trout occur in portions of the Columbia River and Snake River basins, extending east to headwater streams in Montana and Idaho, and into Canada. Bull trout also occur in the Klamath River basin of south- central Oregon. East of the Continental Divide in Canada, the bull trout's range includes the headwaters of the Saskatchewan River in Alberta, and the MacKenzie River system in Alberta and British Columbia. 97. Bull trout were first described as Salmo spectabilis by Girard in 1856 from a specimen collected on the lower Columbia River near The Dalles, Oregon, and subsequently described under a number of names such as Salmo confluentus and Salvelinus malma. Bull trout and Dolly Varden ( Salvelinus malma) were previously considered a single species. However, in 1980, the American Fisheries Society formally recognized bull trout and Dolly Varden as separate species. Two of the most useful characteristics in separating the two species are the shape and size of the head. The head of bull trout is more broad and flat on top, unlike Dolly Varden. Bull trout have an elongated body and large mouth, with the maxilla ( jaw) extending beyond the eye and with well- developed teeth on both jaws and head of the vomer ( a bone in teleost fishes that form the front part of the roof of the mouth and often bears teeth). Bull trout have 11 dorsal fin rays, nine anal fin rays, and the caudal fin is slightly forked. Although they are often olive green to brown with paler sides, color is variable with locality and habitat. 98. Bull trout exhibit both resident and migratory life history strategies. Resident bull trout complete their entire life cycle in the tributary streams where they spawn and rear. Migratory bull trout spawn in tributary streams where juvenile fish rear from one to four years before migrating to either a larger river or lake, where they spend their adult life, returning to the tributary stream only to spawn. These migratory forms occur in areas where conditions allow for movement from upper watershed spawning streams to larger downstream waters that contain greater foraging opportunities. Bull trout that migrate to a downstream river are referred to as " fluvial" fish, while the term " adfluvial" is used to describe fish that migrate to a lake or reservoir. Resident and migratory forms may spawn in the same areas and either form can produce resident or migratory offspring. 7 Information on the bull trout and its habitat is taken from the U. S. Fish and Wildlife Service, Proposed Designation of Critical Habitat for the Klamath River and Columbia River Distinct Population Segments of Bull Trout, November 29, 2002 ( 67 FR 71235- 71284). 1- 2 99. The Klamath River population segment consists of bull trout in the Upper Klamath Lake, Sprague River, and Sycan River watersheds in Oregon. Historical records suggest that bull trout were once widely distributed and exhibited diverse life- history traits in the Klamath River basin. Currently, bull trout in this basin are non- migratory fish that are confined to headwater streams. The local populations that remain reside in an estimated 21 percent of the historic range of bull trout in the Klamath River basin, and they are isolated from one another. 100. The Columbia River population segment includes bull trout residing in portions of Oregon, Washington, Idaho, and Montana. The Bull Trout Draft Recovery Plan ( Draft Recovery Plan) ( Service 2002) identifies 22 recovery units within the Columbia River basin: the Willamette River ( upper tributaries including the McKenzie River), Lower Columbia River ( principally the Lewis, White Salmon, and Klickitat Rivers), Hood River, Deschutes River, Odell Lake, John Day River, Umatilla and Walla Walla Rivers, Middle Columbia River ( principally the Yakima River), Snake River ( including Asotin Creek and Tucannon River), Grande Ronde River, Clearwater River, Salmon River, Little Lost River, Imnaha River, Hells Canyon ( including Powder River), Malheur River, Southwest Idaho, Upper Columbia River ( principally the Wenatchee, Entiat, and Methow Rivers), Northeast Washington, Clark Fork River, Kootenai River, and Coeur d'Alene Lake. Bull trout are estimated to have once occupied about 60 percent of the Columbia River basin; they presently occur in approximately 45 percent of their historic range. Although still somewhat widely distributed in the Columbia River basin, bull trout occur in low numbers in many areas and populations are considered depressed or declining across much of their range. 101. Many factors have contributed to the decline of bull trout in the Columbia and Klamath River basins. However, several appear to be particularly significant: ( 1) fragmentation and isolation of local populations due to dams and water diversions that have eliminated habitat, altered water flow and temperature regimes, and impeded migratory movements; ( 2) degradation of spawning and rearing habitat in upper watershed areas, particularly alterations in sedimentation rates and water temperature resulting from past forest and rangeland management practices and intensive development of roads; and ( 3) the introduction and spread of non- native species, particularly brook trout ( Salvelinusfontinalis) and lake trout ( Salvelinus namaycush), which compete with bull trout for limited resources and, in the case of brook trout, hybridize with bull trout. 102. Bull trout have more specific habitat requirements than most other salmonids. Habitat components that influence bull trout distribution and abundance include water temperature, cover, channel form and stability, spawning and rearing substrate conditions, and migratory corridors. 103. Bull trout are found primarily in cold streams; water temperatures above 15° Celsius ( C) ( 59° Fahrenheit ( F)) are believed to limit bull trout distribution. Adult bull trout have been observed in large rivers throughout the Columbia River basin in water temperatures up to 20° C ( 68° F); however, there are documented steady and substantial declines in 1- 3 abundance in stream reaches where water temperature ranged from 15° to 20° C ( 59° to 68° F). In large rivers, bull trout are often observed " dipping" into the lower reaches of tributary streams, and it is suspected that cooler waters in these tributary mouths may provide important thermal refugia, allowing them to forage, migrate, and overwinter in waters that would otherwise be, at least seasonally, too warm. 104. Preferred spawning habitat consists of low- gradient stream reaches with loose, clean gravel, and water temperatures that range from 4° to 10° C ( 39° to 51° F). Such areas are often associated with cold- water springs or groundwater up- welling. Because bull trout eggs incubate about seven months in the gravel, they are especially vulnerable to fine sediments and water quality degradation. Increases in fine sediment appear to reduce egg survival and emergence. Juveniles are likely similarly affected, as they also live on or within the stream bed cobble. 105. Throughout their lives, bull trout require complex forms of cover, including large woody debris, undercut banks, boulders, and pools. Bull trout are opportunistic feeders, with food habits that are primarily a function of size and life- history strategy. Resident and juvenile migratory bull trout prey on terrestrial and aquatic insects, macro- zooplankton, and small fish. Adult migratory bull trout feed almost exclusively on other fish. 106. The ability to migrate is important to the persistence of bull trout. Maintaining the full complement of bull trout life history forms appears to be important for long- term population persistence in a dynamic and unpredictable environment. Migratory bull trout become much larger than resident fish in the more productive waters of larger streams and lakes, leading to increased reproductive potential. Migration also results in increased dispersion of the population which facilitates gene flow among local populations when individuals from different local populations interbreed, stray, or return to non- natal streams. Local populations that are extirpated by catastrophic events may also become re- established by bull trout migrants. 107. Introduced brook trout threaten bull trout through hybridization, competition, and possibly predation. Hybridization between brook trout and bull trout has been reported in Montana, Oregon, Washington, and Idaho. In addition, brook trout mature at an earlier age and have a higher reproductive rate than bull trout. This difference appears to favor brook trout over bull trout when they occur together, often leading to the decline or extirpation of bull trout. Brook trout also appear to adapt better to degraded habitat than bull trout and are more tolerant of high water temperatures. Non- native lake trout also negatively affect bull trout. In a study of 34 lakes in Montana, Alberta, and British Columbia, lake trout appeared to limit foraging opportunities and reduce the distribution and abundance of migratory bull trout in mountain lakes. 108. The Service determined the primary constituent elements of bull trout habitat from studies of their habitat requirements, life history characteristics, and population biology, as outlined above. These primary constituent elements are: 1- 4 Permanent water and associated substrate having low levels of contaminants such that normal reproduction, growth and survival are not inhibited; Water temperatures ranging from 2° to 15° C ( 37° to 59° F). Adequate thermal refugia may be necessary for persistence of bull trout if water temperatures commonly exceed this range. Specific temperatures within this range will vary depending on bull trout life history stage and form, geography, elevation, diurnal and seasonal variation, shade, such as that provided by riparian habitat, and local groundwater influence; • Complex stream channels with features such as woody debris, side channels, pools, and undercut banks to provide a variety of depths, velocities, and instream structures; • Substrates of sufficient amount, size, and composition to ensure success of egg and embryo overwinter survival, fry emergence, and young- of- the- year and juvenile survival. A minimal amount of fines less than 0.63 cm ( 0.25 in) in diameter and minimal substrate embeddedness are characteristic of these conditions; • A natural hydrograph, including high, low, peak, and base flows within historic ranges or, if regulated, a hydrograph that demonstrates the ability to support bull trout populations; • Springs, seeps, groundwater sources, and subsurface water connectivity to contribute to water quality and quantity; • Migratory corridors with minimal physical, biological or chemical barriers between spawning, rearing, overwintering, and foraging habitats, including intermittent or seasonal barriers induced by high water temperatures or low flows; • An abundant food base including terrestrial organisms of riparian origin, aquatic macroinvertebrates, and forage fish; and • Few or no predatory, interbreeding, or competitive non- native species present. An area need not include all of these elements to qualify for designation as critical habitat. 1.2 Proposed Critical Habitat 109. The areas proposed for designation as critical habitat for the bull trout provide one or more of the primary constituent elements described above. All of the proposed areas require special management considerations to ensure their contribution to the conservation of the bull trout. The critical habitat area consists of 18,469 river miles and 532,721 acres of lake and reservoir habitat within 25 units. While the lateral extent of proposed riverine 1- 5 critical habitat is the width of the stream channel defined by its bankfull elevation, the designation of critical habitat is expected to impact inland activity. How far inland the designation's effects extend is a more or less a site specific issue. For example, with regards to land- based activities such as timber sales or grazing practices, it is a matter of site specific physical processes such as sediment transport, the local topography, and the size of the drainage basin. Descriptions of each critical habitat unit are provided in Appendix A. 1.3 Framework and Methodology 110. The primary purpose of this analysis is to estimate the economic impact associated with the designation of critical habitat for bull trout. 8 This information is intended to assist the Secretary in making decisions about whether the benefits of excluding particular areas from the designation outweigh the benefits of including those areas in the designation. 9 In addition, this information allows the Service to address the requirements of Executive Orders 12866 and 13211, the RFA, as amended by the SBREFA. 10 111. This chapter provides the framework for this analysis. First, it defines the economic effects considered in the analysis. Second, it establishes the baseline against which these effects are measured. Third, it describes the measurement of direct compliance costs, which include costs associated with, and generated as a result of, section 7 consultations. Fourth, it identifies potential indirect economic effects of the rule resulting from ( 1) compliance with other parts of the Act potentially triggered by critical habitat, ( 2) compliance with other laws, and ( 3) time delays and regulatory uncertainty. Fifth, it discusses the need for an economic assessment of the benefits of critical habitat designation. Finally, the section concludes by discussing the time frame for the analysis and the general steps followed in the analysis. 1.3.1 Types of Economic Effects Considered 112. This economic analysis considers both the economic efficiency and distributional effects. For the purpose of this analysis, economic efficiency effects generally reflect the " opportunity costs" associated with the commitment of resources required to comply with the Act. For example, if the activities that can take place on a parcel of private land are limited as a result of a designation, and thus the market value of the land reduced, this reduction in value represents one measure of opportunity cost or change in economic efficiency. Similarly, the costs incurred by a Federal Action agency to consult with the Service under section 7 represent economic opportunity costs. 8 This analysis considers the effects of the regulatory action as proposed in the Federal Register on November 29, 2002 ( 67 FR 71236). M6U. S. C. § 1533( b)( 2). 10 Executive Order 12866, " Regulatory Planning and Review," September 30, 1993; Executive Order 13211, " Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use," May 18, 2001; 5 U. S. C. § § 601 etseq; and Pub Law No. 104- 121. 1- 6 113. This analysis also addresses how the impacts are distributed, including an assessment of any local or regional economic impacts and the potential effects on small entities and the energy industry. This information can be used by decision- makers to assess whether the effects might unduly burden a particular group or economic sector. 114. For example, while the designation may have a relatively small impact when measured in terms of changes in economic efficiency, individuals employed in a particular sector of the economy in the geographic area of the designation may experience relatively greater effects. The difference between economic efficiency effects and distributional effects, as well as their application in this analysis, are discussed in greater detail below. Efficiency Effects 115. At the guidance of the OMB and in compliance with Executive Order 12866 " Regulatory Planning and Review," Federal agencies measure changes in economic efficiency in order to understand how society, as a whole, will be affected by a regulatory action. 11 In the context of this regulatory action, these efficiency effects represent the opportunity cost of resources used or benefits foregone by society as a result of critical habitat designation and other co- extensive regulations. 12 Economists generally characterize opportunity costs in terms of changes in producer and consumer surpluses in affected markets. 13 116. In some instances, compliance costs may provide a reasonable approximation for the efficiency effects associated with a regulatory action. For example, a landowner or manager may need to enter into a consultation with the Service to ensure that a particular activity will not adversely modify critical habitat. The effort required for the consultation represents an economic opportunity cost, because the landowner or manager's time and effort would have been spent in an alternative activity had the parcel not been included in the designation. When compliance activity is not expected to significantly affect markets — that is, not result in a shift in the quantity of a good or service provided at a given price, or in the quantity of a good or service demanded given a change in price ~ the measurement of compliance costs can provide a reasonable estimate of the change in economic efficiency. 11 Executive Order 12866, " Regulatory Planning and Review," September 30,1993; U. S. Office of Management and Budget, " Circular A- 4," September 17, 2003. 12 The term " co- extensive" is discussed in greater detail in Section 1.3.3. 13 For additional information on the definition of " surplus" and an explanation of consumer and producer surplus in the context of regulatory analysis, see Gramlich, Edward M, A Guide to Benefit- Cost Analysis ( 2nd Ed.), Prospect Heights, Illinois: Waveland Press, Inc., 1990; and U. S. EPA, Guidelines for Preparing Economic Analyses, EPA 240- R- 00- 003, September 2000, available at http:// yosemite. epa. gov/ ee/ epa/ eed. nsf/ webpages/ Guidelines. html. 1- 7 117. Where a designation is expected to significantly impact a market, it may be necessary to estimate changes in producer and consumer surpluses. For example, a designation that precludes the development of large areas of land may shift the price and quantity of housing supplied in a region. In this case, changes in economic efficiency can be measured by considering changes in producer and consumer surplus in the real estate market. 118. This analysis begins by measuring reasonably foreseeable compliance costs. As noted above, in some cases, compliance costs can provide a reasonable estimate of changes in economic efficiency. However, if the designation is expected to significantly impact markets, the analysis will consider potential changes in consumer and/ or producer surplus in affected markets. Distributional and Regional Economic Effects 119. Measurements of changes in economic efficiency focus on the net impact of the regulation, without consideration for how certain economic sectors or groups of people are affected. Thus, a discussion of efficiency effects alone may miss important distributional considerations concerning groups that may be disproportionately affected. OMB encourages Federal agencies to consider distributional effects separately from efficiency effects. 14 This analysis considers the potential for several types of distributional effects, including impacts on small entities; impacts on energy supply distribution and use; and regional economic impacts. It is important to note that these are fundamentally different measures of economic impact than efficiency effects, and thus cannot be added to or compared with estimates of changes in economic efficiency. Impacts on Small Entities and Energy Supply, Distribution and Use 120. This analysis considers how small entities, including small businesses, organizations, and governments, as defined by the RFA, might be affected by critical habitat designation and other co- extensive regulatory actions. 15 In addition, in response to Executive Order 13211 " Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use," this analysis considers the impacts of critical habitat on the energy industry and its customers. 16 14 U. S. Office of Management and Budget, " Circular A- 4," September 17, 2003. 155U. S. C. § 60\ etseq. 16 Executive Order 13211, " Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use," May 18, 2001. 1- 8 Regional Economic Effects 121. Regional economic impact analysis provides an assessment of the potential localized effects of critical habitat designation and other co- extensive regulations. Specifically, regional economic impact analysis produces a quantitative estimate of the potential magnitude of the initial change in the regional economy resulting from a regulatory action. Regional economic impacts are commonly measured using regional input/ output models. These models rely on multipliers that mathematically represent the relationship between a change in one sector of the economy ( e. g., hydroelectric power generation) and the effect of that change on economic output, income, or employment in other local industries ( e. g., manufacturers relying on the electricity generated). These economic data provide a quantitative estimate of the magnitude of shifts of jobs and revenues in the local economy. 122. The use of regional input/ output models can overstate the long- term impacts of a regulatory change. Most importantly, these models provide a static view of the economy of a region. That is, they measure the initial impact of a regulatory change on an economy but do not consider long- term adjustments that the economy will make in response to this change. For example, these models provide estimates of the number of jobs lost as a result of a regulatory change, but do not consider re- employment of these individuals over time. In addition, the flow of goods and services across the regional boundaries defined in the model may change as a result of the designation, compensating for a potential decrease in economic activity within the region. 123. Despite these and other limitations, in certain circumstances regional economic impact analysis may provide useful information about the scale and scope of localized impacts. It is important to remember that measures of regional economic effects generally reflect shifts in resource use rather than efficiency losses. These types of distributional effects, therefore, should be reported separately from efficiency effects ( i. e., not summed). In addition, measures of regional economic impact cannot be compared with estimates of efficiency effects. 1.3.2 Defining the Baseline 124. The purpose of this analysis is to measure the economic impact of compliance with the protections derived from the designation of critical habitat, including habitat protections that may be " co- extensive" with the listing of the species ( the term " co- extensive" is described in greater detail in the following section). Economic impacts to land use activities may exist in the absence of co- extensive protections. These impacts may result from, for example: • Local zoning laws; • State and natural resource laws; and 1- 9 • Enforceable management plans and BMPs applied by other State and Federal agencies. 125. Economic impacts that result from these types of protections are not included in this assessment; they are considered to be part of the " baseline." Existing laws, regulations, and policies are described in greater detail in Section 2.3 of this analysis. 1.3.3 Direct Compliance Costs 126. The measurement of direct compliance costs focuses on the implementation of section 7 of the Act. This section requires Federal agencies to consult with the Service to ensure that any action authorized, funded, or carried out will not likely jeopardize the continued existence of any endangered or threatened species or result in the destruction or adverse modification of critical habitat. The administrative costs of these consultations, along with the costs of project modifications resulting from these consultations, represent the direct compliance costs of designating critical habitat. 127. This analysis does not differentiate between consultations that result from the listing of the species ( i. e., the jeopardy standard) and consultations that result from the presence of critical habitat ( i. e., the adverse modification standard). Consultations resulting from the listing of the species, or project modifications meant specifically to protect the species as opposed to its habitat, may occur even in the absence of critical habitat. However, in 2001, the U. S. 10th Circuit Court of Appeals instructed the Service to conduct a full analysis of all of the economic impacts of critical habitat designation, regardless of whether those impacts are attributable co- extensively to other causes. 17 Given the similarity in regulatory definitions between the terms " jeopardy" and " adverse modification," in practice it can be difficult to pre- determine the standard that drives a section 7 consultation. Consequently, in an effort to ensure that this economic analysis complies with the instructions of the 10th Circuit as well as to ensure that no costs of the proposed designation are omitted, the potential effects associated with all section 7 impacts in or near proposed critical habitat are fully considered. In doing so, the analysis ensures that any critical habitat impacts that are co- extensive with the listing of the species are not overlooked. 1.3.4 Indirect Costs 128. A designation may Close

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.

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

The biological opinion (BO) addressing this BA and any subsequent BA amendments will be among the information that will inform the development of alternatives of the long-term operations plan and environmental impact statement (EIS). Reclamation is developing a long-term operations plan and EIS for the Project. The preferred alternative for implementation from the long-term operations plan would be the subject of a separate future ESA consultation. This BA describes the needs of anadromous fish with emphasis on SONCC coho salmon. It was developed using the best available scientific and commercial information on anadromous fish in the Klamath River. Coho salmon were listed as threatened on June 6, 1997 (NMFS 1997). The NMFS published a final rule designating critical habitat for SONCC coho salmon in May, 1999 (NMFS 1999a). Designated critical habitat for SONCC coho salmon encompasses accessible reaches of all rivers (including estuarine areas and tributaries) between the Mattole River in California and the Elk River in Oregon. Critical habitat includes all waterways, substrate, and adjacent riparian zones below longstanding, naturally impassable barriers. The areas upstream from Iron Gate Dam (IGD) (river mile 190) were not proposed critical habitat because areas downstream were considered sufficient for the conservation of the species. Reclamation has not evaluated whether the action that is the subject of this BA is consistent with its trust responsibility to Klamath Basin Indian Tribes. There are several important scientific reports and analyses (e.g., Phase II flow study) currently not available to Reclamation concerning threatened coho salmon, their habitat, and water quality as it relates to appropriate river flows that may be necessary to operate the Project consistent with the trust responsibility to Klamath Basin Indian Tribes. When this additional information becomes available, Reclamation intends to consider it during the development of the Project operations plans and include it in subsequent consultations with NMFS, as appropriate.

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.

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

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

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

Year: 2003, 2005, 2004 Klamath River Fish Die-off, September 2002, Mortality Report, FWS, Arcata, CA Summary of Findings This report provides an estimate of the fish mortality that occurred during the September 2002 Klamath River die-off. The intent of this report is to provide natural resource agencies and trustees with information describing the magnitude of this event for their consideration in near-term decisions regarding the affected fisheries resources and related assets under their authority. The Fish and Wildlife Service (Service), in cooperation with other federal and state agencies and Tribes, will continue to collaborate and evaluate information collected during the die-off. This report describes a conservative assessment, which probably underestimates the total number of fish that died during this event. Findings described in this report include the following: 22 The most accurate estimate of the total number of observable fish that died during the incident is 34,056. 22 Approximately 98.4 percent of the dead fish observed were adult anadromous salmonids 22 Out of 33,527 anadromous salmonids estimated to have succumbed during this event, 97.1 percent (32,533) were fall-run Chinook salmon, Oncorhynchus tshawytscha, 1.8 percent (629) were steelhead, O. mykiss, and 1.0 percent (344) were coho salmon, O. kisutch. Only one coastal cutthroat, O. clarki clarki was found dead during the investigation. 22 Approximately 91.5 percent of the coho salmon, and 38.7 percent of the steelhead observed had marks indicating that they were of hatchery origin. All hatchery coho originated from the Trinity River Hatchery. After accounting for variable tagging and shed rates, the Klamath River Technical Advisory Team (KRTAT) estimated that 7,060 (21.7 percent) Chinook were of hatchery origin. A total of 2,921 (9 percent) Chinook were of Iron Gate (Klamath River) Hatchery origin. A total of 4,139 (12.7 percent) Chinook were of Trinity River Hatchery origin. 22 The KRTAT also estimated that dead Chinook salmon represented 19.2 percent of the total (169,,297) in-river Klamath-Trinity River run. 22 Other dead fish observed during the investigation included sculpins, Cottus spp. (87 fish), speckled dace, Rhinichthys osculus (9 fish), Klamath smallscale sucker, Catostomus rimiculus (311 fish), one American shad, Alosa sapidissima, and one green sturgeon, Acipencer medirostris. ii Klamath River Fish Die-off, September 2002, Mortality Report, FWS, Arcata, CA 22 Throughout the investigation, live adult and juvenile fish of affected and unaffected species were observed in the river. In addition, some species (e.g. American shad, speckled dace, and green sturgeon) did not appear to experience extensive mortality. Almost all (greater than 99 percent) of the dead fish observed were adults or larger species offish. 22 The majority of the recently dead fish examined exhibited one or more outward gross signs of disease including gill necrosis, bacterial growth, sores, bloody vents, and ulcerations. Pathological examinations confirmed that white spot disease and columnaris were the principle immediate causes of death. Additional information collected by the Service and cooperating agencies included a suite of water quality parameters collected during the summer and fall of 2001 and 2002, fish pathology analyses, and related hydrologic information. The Service will provide reports on this additional information after it has received quality assurance review.

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. Lake elevation is controlled at the outlet by Link River 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.

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. Lake elevation is controlled at the outlet by Link River Close
