On January 6, 1961, Seattle City Light completes Gorge High Dam on the upper Skagit River, in southeast Whatcom County. The dam is 300 feet high. The combination gravity-arch concrete structure diverts water to a tunnel, which connects to a powerhouse two miles downstream.

The project ultimately cost approximately $29 million, twice the original estimate.
