Baker Hydroelectric Project

Puget Sound; Baker River, Whatcom and Skagit Counties, Washington

Project Profile

The Upper and Lower Baker Dams blocked downstream juvenile passage for ESA-listed fish. Fish passage engineers and biologists designed a first-of-its-kind floating surface collector, which has increased juvenile salmon passage survival from less than 60% of fish successfully migrating past the Upper Baker Dam to 75 to 95%.
