Sonoma County supervisors agreed Tuesday to study the possibility of applying for a license to operate a remote Mendocino County hydropower project, marking the first move to maintain a long-standing water transfer deemed critical to residents and ranchers in both counties.
A coalition of five Mendocino County agencies and California Trout, a 50-year-old environmental nonprofit, are collaborating with Sonoma County’s water agency in the consideration of taking over the federal license for the Potter Valley Project, which delivers 20 billion gallons of water a year from the Eel River into the Russian River basin.
Each of the three partners is putting $100,000 into the study, an amount dwarfed by the potential cost of establishing free passage for the Eel River’s protected salmon and steelhead — likely a requisite step to extend the project’s life.
PG&E, the state’s largest utility now in bankruptcy, surrendered the project in January, upending the license renewal process, and no entity has responded to a Federal Energy Regulatory Commission (FERC) call for a new operator.
The utility, which had owned the project since 1930, said it was no longer economical to operate a plant that generated less than 1 percent of its power.
But the water flowing through the powerhouse is virtually invaluable to the towns and ranches along the upper Russian River from Potter Valley to Healdsburg and is a critical source for Sonoma Water, which delivers water to 600,000 Sonoma and Marin county customers.
