Welcome to the Columbia Basin Fish & Wildlife Program
Bonneville Power Administration funds work to protect and restore the fish and wildlife affected by hydroelectric dams on the Columbia River and its tributaries. CBFish tracks that work — the projects, the contracts, and what they achieve — across Idaho, Montana, Oregon, and Washington.
