The Tumwater Dam was constructed from 1907 to 1909 and was the largest hydroelectric project in the American West when it was built. It provided power for electric locomotives running on the Great Northern Railway through the tunnel at Steven's Pass. The project was closed in 1956 but the dam remains.
