May 18, 2019. The Sonoma County Water Agency (Sonoma Water), Mendocino Inland Water and Power Commission, and California Trout, Inc. are working towards adopting a Potter Valley Project (Project) planning agreement to secure the region’s water supply and protect endangered salmon species in the Eel River and upper Russian River. Driven by an ad hoc process facilitated by Congressman Jared Huffman, the planning agreement will provide a structure to fund and develop a collaborative two basin proposal for the future of the Project to support water resources and fisheries restoration in both watersheds.
