Description

The Tumwater Dam was constructed from 1907 to 1909 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. In the past the dam was occassionally run but a project to repair and reinforce the dam's apron 2024 resulted in placement of large rocks at the base of the dam creating a hazard. The dam is located at Highway 2 mile 95.1. A small pull out and access below the dam is used as a put-in for those desiring a short run.
