Elwha Powerhouse

The Elwha River Hydroelectric System consisted of two dams and power plants, Elwha and Glines Canyon, and were located on the northern Olympic Peninsula in Washington State.

The Elwha River Ecosystem and Fisheries Restoration Act of 1992 authorized the US Federal Government to acquire the Elwha Dam and Glines Canyon Dam hydroelectric power projects for decommissioning and demolition for habitat restoration. The removal of the first of the two dams, the Elwha Dam, began in September 2011 and was completed ahead of schedule in spring 2012. The Glines Canyon Dam was removed in 2014.
