‚ÄčYakima Fisheries Project (DOE/EIS-0169)

The Yakima Fisheries Project is an ongoing project that involves studies, research, and artificial production of spring Chinook, fall Chinook, and coho salmon in the Yakima basin. Studies and research are conducted on the effectiveness of hatchery supplementation and interactions of hatchery fish with the environment. An environmental impact statement was prepared for the initiation of the project in 1996, and several supplement analyses tiered to this environmental impact statement have been prepared subsequently as the program has been modified and adapted to the results of the ongoing research.

For further information on this project, please contact or 503-230-4628.
