Woods Creek Hydro Project

Take our virtual tour:

The Woods Creek Hydroelectric Project is located north of the city of Monroe, Washington, and has a nameplate capacity of 0.65 MW. The project is adjacent to Woods Creek, a tributary of the Skykomish River, with a powerhouse located at a natural impassible barrier to fish. Prior to acquisition of this small hydroelectric resource in 2008, the PUD had purchased 100% of the output since its construction in 1982.
