Hydropower in Hood Canal

Dam relicensing improves management of flows, habitat, and fish

The Cushman Project includes two hydropower dams built in 1926 on the North Fork Skokomish River. The entire river was diverted to a power house on Hood Canal at Potlatch. The resulting fish blockages, decreased water flow, and habitat degradation contributed to the loss of summer chum salmon. Fortunately, the 2010 relicensing of the dam included improved management of flows, habitat, and fish. A variety of habitat restoration efforts designed to improve the number of salmon are underway from the headwaters to the estuary.
