Letter writing workshop will urge regulators to swiftly remove Potter Valley Project dams

The hydropower Potter Valley Project includes the Scott and Cape Horn dams, two century-old dams on the Eel River. It also has a mile-long diversion tunnel that feeds water from the Eel River into the Russian River.

Sierra Club Mendocino Group chapter director Alicia Bales and Friends of the Eel River’s executive director Alicia Hamann will answer questions Friday in Willits about the Potter Valley Project, including how the dams have affected fish in the Eel River and what relief removing the dams may bring.
