Wynoochee River Project

Wynoochee DamThe Wynoochee River Project generates clean, renewable electricity using water released from Wynoochee Lake in Grays Harbor County, Washington.

Wynoochee Dam was completed in 1972 by the U.S. Army Corps of Engineers for flood control and other water-management purposes. Hydroelectric generation was added later, with the powerhouse beginning operation in 1994. Today, Tacoma Power operates the hydroelectric facilities while supporting fish and wildlife, recreation and environmental stewardship in the Wynoochee River basin.
