Author: U.S. Fish and Wildlife Service Year: 2003, 2008, 2005 EXECUTIVE SUMMARY FOR THE BULL TROUT RECOVERY PLAN Current Species Status The bull trout (Salvelinus confluentus) in the coterminous United States was listed as threatened on November 1, 1999 (64 FR 58910). Earlier rulemakings had listed distinct population segments of bull trout as threatened in the Columbia River, Klamath River, and Jarbidge River basins (63 FR 31647, 63 FR 42757, 64 FR 17110). Bull trout distribution, abundance, and habitat quality have declined rangewide. Several local extirpations have been documented, beginning in the 1950fs. Bull trout continue to occur the Klamath River, Columbia River, Jarbidge River, St. Mary-Belly River, and Coastal-Puget Sound, in the states of Idaho, Montana, Nevada, Oregon, and Washington. Habitat Requirements and Limiting Factors 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, substrate for spawning and rearing, and migratory corridors. Bull trout are found in colder streams and require colder water than most other salmonids for incubation, juvenile rearing, and spawning. Spawning and rearing areas are often associated with cold-water springs, groundwater infiltration, and/or the coldest streams in a watershed. Throughout their lives, bull trout require complex forms of cover, including large woody debris, undercut banks, boulders, and pools. Alterations in channel form and reductions in channel stability result in habitat degradation and reduced survival of bull trout eggs and juveniles. Channel alterations may reduce the abundance and quality of side channels, stream margins, and pools, which are areas bull trout frequently inhabit. For spawning and early rearing bull trout require loose, clean gravel relatively free of fine sediments. Because bull trout have a relatively long incubation and development period within spawning gravel (greater than 200 days), transport of bedload in unstable channels may kill young bull trout. Bull trout use migratory corridors to move from spawning and rearing habitats to foraging and overwintering habitats and back. Different habitats provide bull trout with diverse resources, and migratory corridors allow local populations to connect, which may increase the potential for gene flow and support or refounding of populations. Declines in bull trout distribution and abundance are the results of combined effects of the following: habitat degradation and fragmentation, the blockage of migratory corridors, poor water quality, angler harvest and poaching, entrainment (process by which aquatic organisms are pulled through a diversion structure or other device) into diversion channels and dams, and introduced iv normative species. Specific land and water management activities that continue to depress bull trout populations and degrade habitat include dams and other diversion structures, forest management practices, livestock grazing, agriculture, road construction and maintenance, mining, and urban and rural development. Some threats to bull trout are the continuing effects of past land management activities. Organization and Development of the Recovery Plan Because bull trout in the coterminous United States are widely distributed within a large area, the recovery plan is organized into multiple chapters. This introductory chapter (Chapter 1) describes our overall recovery strategy for the species, defines recovery, and identifies recovery actions applicable for all listed bull trout in the coterminous United States. Each successive chapter focuses on bull trout in specific geographic areas (recovery units), and describes conditions, defines recovery criteria, and identifies specific recovery actions for the recovery unit. Recovery Objectives The goal of this recovery plan is to describe the actions needed to achieve the recovery of bull trout, that is, to ensure the long-term persistence of self-sustaining, complex interacting groups (or multiple local populations that may have overlapping spawning and rearing areas) of bull trout distributed across the species' native range. Recovery of bull trout will require reducing threats to the long-term persistence of populations, maintaining multiple interconnected populations of bull trout across the diverse habitats of their native range, and preserving the diversity of bull trout life-history strategies (e.g., resident or migratory forms, emigration age, spawning frequency, local habitat adaptations). To recover bull trout, the following four objectives have been identified: ? Maintain current distribution of bull trout within core areas as described in recovery unit chapters and restore distribution where recommended in recovery unit chapters. ? Maintain stable or increasing trend in abundance of bull trout. ? Restore and maintain suitable habitat conditions for all bull trout life history stages and strategies. ? Conserve genetic diversity and provide opportunity for genetic exchange. ? These objectives apply to bull trout in all recovery units. Additional objectives may be necessary to achieve recovery in some recovery units and will be identified in the respective recovery unit chapters. Recovery Criteria Criteria are established to assess whether recovery objectives are being achieved. Criteria specific to each recovery unit are defined in each recovery unit chapter. Individual chapters may contain criteria for assessing the status of bull trout and alleviation of threats that are unique to one or several recovery units. However, every recovery unit chapter will contain criteria that address the following characteristics: ? The distribution of bull trout in identified and potential local populations in all core areas within the recovery unit. ? The estimated abundance of adult bull trout within core areas in the recovery unit, expressed as either a point estimate or a range of individuals. ? The presence of stable or increasing trends for adult bull trout abundance in the recovery unit. ? The restoration of passage at specific barriers identified as inhibiting recovery. We expect recovery of bull trout to be a dynamic process occurring over time. The recovery objectives are based on our current knowledge and may be refined as more information becomes available. Some local populations of bull trout, and possibly core area populations, may be extirpated even though recovery actions are being implemented. If reestablishment of recently extirpated populations is not feasible or practical, recovery criteria for a given recovery unit will be revised on a case-by-case basis. Meeting the four recovery criteria is not intended to be precluded where localized extirpations of bull trout are offset by sufficiently strong improvements in other areas of a recovery unit in meeting the four recovery objectives. The determination of whether a distinct population segment of bull trout is recovered will rely on an analysis of the overall status of the species, threats to the species, and the adequacy of existing regulatory and conservation mechanisms. For example, it may be possible for the Columbia River Distinct Population Segment, which has 22 recovery units, to be recovered prior to all recovery unit criteria being met in all recovery units. Success in accomplishing the recovery VI criteria will be reviewed and considered for the impacts both within a recovery unit and throughout a distinct population segment. Actions Needed Specific tasks falling within the following seven categories will be necessary to initiate recovery within all recovery units: ? Protect, restore, and maintain suitable habitat conditions for bull trout. ? Prevent and reduce negative effects of normative fishes and other normative taxa on bull trout. ? Establish fisheries management goals and objectives compatible with bull trout recovery and implement practices to achieve goals. ? Characterize, conserve, and monitor genetic diversity and gene flow among local populations of bull trout. ? Conduct research and monitoring to implement and evaluate bull trout recovery activities, consistent with an adaptive management approach using feedback from implemented, site-specific recovery tasks. ? Use all available conservation programs and regulations to protect and conserve bull trout and bull trout habitats. ? Assess the implementation of bull trout recovery by recovery units and revise recovery unit plans based on evaluations. Recovery Priority Number The recovery priority number for bull trout in the coterminous United States is 9C, on a scale of 1 to 18, indicating that (1) taxonomically, these populations are distinct population segments of a species, (2) the five populations are subject to a moderate degree of threat(s), (3) the recovery potential is high, and (4) the degree of potential conflict during recovery is high. vrr Estimated Cost of Recovery The total cost estimate of recovery for bull trout in the coterminous United States is presented in the individual recovery unit chapters. The costs presented in each chapter are attributed to bull trout conservation but other species will also benefit. Date of Recovery Expected time to achieve recovery varies among recovery units because of differences in bull trout status, factors affecting bull trout, implementation and effectiveness of recovery tasks, and responses to recovery tasks. Achieving bull trout recovery in all recovery units will be a complex process that will likely take 25 years or more. vin Title: Bull Trout, Salvelinus Confluentus...

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

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