DOE/EA-2250: Final Environmental Assessment (May 2025)

Phase II Implementation Plan; Multiple Locations

The Bonneville Power Administration, the U.S. Army Corps of Engineers, and the Bureau of Reclamation, as co-lead agencies, issued a final environmental assessment (EA) for Federal Support for the Phase 2 Implementation Plan: Testing Feasibility of Salmon Reintroduction in the Upper Columbia River Basin (DOE/EA-2250). This EA assesses the potential environmental impacts of federal actions to support a proposal brought forward by the Confederated Tribes of the Colville Reservation, Spokane Tribe of Indians, and Coeur d’Alene Tribe, through and with the assistance of the Upper Columbia United Tribes. The federal actions include permitting requirements and actions, supplying eggs and juvenile and adult salmon from existing hatcheries and non-hatchery collection actions, and providing federal funding for juvenile and adult salmon research studies, development of fish-holding, rearing, and acclimation facilities, and development and testing of interim upstream and downstream fish passage facilities.
