Resident Fish Stock Status above Chief Joseph and Grand Coulee Dams
This project (NWPPC program measure 10.8B.26) is designed and guided jointly by Washington Department of Fish and Wildlife (WDFW), Kalispel Natural Resource Department (KNRD), Spokane Tribe of Indians (STI), and Confederated Tribes of the Colville Reservation (CCT).
The purpose of this project is collect and assess information on blocked area fisheries. It has three phases set to enhance the fisheries resources of the blocked area:
- Identify data gaps
- Filling data gaps with research
- Implementing management recommendations based on research results
Information on blocked area fisheries in one central location will allow managers to view the entire system for making decisions, rather than basing management decisions on isolated portions of the system. Please see the reports page to view our annual reports.
Genetic Inventory of Bull Trout and Westslope Cutthroat Trout in the Pend Oreille Sub-basin
Finished in January of 2004, this three year project was funded by Bonneville Power Administration (BPA) (Project No. 2002-043-00). The purpose of the study was to comprehensively identify the genetic characteristics for bull trout and Westslope cutthroat trout within the Pend Oreille Sub-basin. The research also evaluated the level of hybridization between bull and brook, and Westslope cutthroat and rainbow trout. The project’s outcomes have enabled managers to identify core areas (watersheds) where recovery efforts can be implemented.
Restoration of Bull Trout Passage at Albeni Falls Dam
Recovery of Pend Oreille bull trout is limited by the fact that dams on the mainstream Pend Oreille River, including Albeni Falls and Box Canyon dams, have blocked migration of bull trout between Lake Pend Oreille and spawning areas. Albeni Falls Dam is a federal facility under the responsibility of the U.S. Army Corps of Engineers, Bonneville Power Administration and Bureau of Reclamation.
The goal of this project is to provide temporary upstream passage for bull trout at Albeni Falls Dam on the Pend Oreille River and then collect and analyze the data. This project provides direct benefits for endangered bull trout in the Pend Oreille Basin because it allows fish, whose migration corridor has been blocked by hydroelectric projects without fish passage, to return to their natal streams.
