Decommissioning the Potter Valley Project: a turning point for Mendocino County
After 100 years of water diversions from the Eel River to the Russian River and the sometimes successful provision of hydroelectric power, license holder PG&E published its Initial Draft Surrender Application and Conceptual Decommissioning Plan for the Potter Valley Project in November. According to the initial plan, Potter Valley Project operations will end and Scott Dam will be removed. The first draft plan is a conceptual overview, which will get more specific over the next two years. The project includes two dams — a larger structure called Scott Dam where water is stored at Lake Pillsbury, and the smaller Cape Horn Dam that creates the Van Arsdale Reservoir. At Cape Horn Dam, a coalition of regional agencies, counties, and tribes has stepped forward to propose keeping a much lower impact water diversion in place.
