Cushman Hydro Project

One of the first major dams in the Pacific Northwest, Tacoma Power's Cushman Dam No. 1 was officially dedicated in 1926 when President Calvin Coolidge pressed a button in the White House to energize the project. The dam is on the North Fork of the Skokomish River near Hood Canal. It is 275 feet high and 1,111 feet long. Lake Cushman has a 23-mile shoreline.

Just downstream, Cushman Dam No. 2 was completed in 1930, forming the small 150-acre Kokanee Lake. This dam measures 235 feet above bedrock and is 575 feet in length.

The powerhouse for Cushman No.2 sits several miles below the dam, overlooking scenic Hood Canal along U.S. Highway 101, the powerhouse attracts hundreds of visitors every year.

Electricity moves from the Cushman Hydro Project to Tacoma on a 40-mile-long transmission line. Construction of the Tacoma Narrows transmission line crossing was a notable engineering achievement of the time. Stretching more than a mile and a quarter between towers in Tacoma and Gig Harbor, the power lines were the longest single span in the world.
