Baker River Hydroelectric Project

Upper Baker Dam

PSE's largest hydropower facility is the Baker River Hydroelectric Project, located on a tributary of the Skagit River in northwest Washington. The project has two dams, each with its own powerhouse. The dams' reservoirs, Baker Lake and Lake Shannon, are fed by runoff from the flanks of Mount Baker and Mount Shuksan.

Lower Baker Dam, completed in 1925, is a 285-foot-high concrete structure with 115 megawatts of power-generating capacity. The 312-foot-high Upper Baker Dam, completed in 1959, has a generating capacity of 100 megawatts. The power project also contains extensive salmon-enhancement systems, including a new fish hatchery and new, innovative facilities for moving migrating fish both upstream and downstream around PSE's two dams.

The project provides numerous amenities for public recreation and flood control for communities in the Skagit River Valley. PSE was awarded a 50-year federal operating license for the project in October 2008
