RESCAT-1995-009-00Proposal Version 1Existing ProjectPending BPA Response1995-009-00Lake Roosevelt Rainbow Trout Net PensThe Federal Governments authorization of hydropower and flood storage development in the Columbia River, known as the "Federal Columbia River Power System" (FCRPS), severely limits indigenous fish populations throughout the Columbia River Basin. Construction and operations of the FCRPS Grand Coulee (1939) and Chief Joseph Dams (1949) has blocked anadromous fish (i.e., salmon, steelhead, sturgeon and lamprey) and adversely altered populations of naturally producing resident fish in the upper Columbia region known as the "blocked area". In lieu of the return of anadromous fish above Grand Coulee Dam and the ability of naturally producing resident fish populations to sustain viable fisheries, artificial production has been determined appropriate for increasing recreational/sport and Tribal subsistence harvest opportunities. The Lake Roosevelt Development Association (Project Proponent/Sponsor) collaborates with the Spokane Tribe, Washington Department of Fish and Wildlife and Colville Confederated Tribes as well as Eastern Washington University to collectively produce rainbow trout (Oncorhynchus mykiss) for release into Lake Roosevelt. Artificial production projects funded by the Bonneville Power Administration (BPA) under directives by the Northwest Power Conservation Council Columbia River Basin Fish & Wildlife Program include the Spokane Tribal Hatchery, the Sherman Creek Hatchery and the Lake Roosevelt Rainbow Trout Net Pen Rearing Projects. Artificial production efforts are monitored and evaluated by the Lake Roosevelt Fisheries Evaluation Program (1994-043-00), also funded by the BPA. The current annual release goal of this project is 750,000 rainbow trout yearlings. The intent of this project is to continue working with the associated artificial production projects to produce rainbow trout for increasing recreational/sport and Tribal subsistence harvest opportunities. Fishery managers have determined an achievable annual harvest goal for hatchery produced rainbow trout is 20% of the release group (150,000 rainbow trout). Triploid rainbow trout will be utilized to limit genetic introgression with naturally occurring populations. All rainbow trout will be marked with adipose fin clips for ongoing RM&E assessments of the hatchery rainbow trout program. This project uses volunteers for work, feeding, and construction of pens to help reduce the cost of the operation.Russell Scranton09/15/201102/26/2014Russell ScrantonLake Roosevelt Development AssociationArtificial ProductionNoneResident Fish, Regional Coordination, and Data Management Category ReviewResident Fish, Regional Coordination, and Data Management Categorical Review
