A group of studies released last month paint a clearer picture of how Sonoma and Mendocino counties can meet future water needs while reducing environmental impacts in the face of a decision by PG&E to cease operation of an aging hydroelectric power project. The Potter Valley Project (PVP) is located approximately 15 miles north of the City of Ukiah on the Eel River. The Project’s facilities include two dams, a diversion tunnel and a hydroelectric plant located in Potter Valley in the headwaters of the Russian River.
