Future of the Eel River to Russian River Trans Basin Diversion (Potter Valley Project)

On April 21, 2026, US Agriculture Secretary Brooke Rollins announced on social media that she had heard from a potential buyer for the Potter Valley Project. The Elsinore Valley Municipal Water District, which serves around 160,000 residential and commercial users in western Riverside County, stated in an interview with the Eureka Times-Standard (linked below) that it “wished to emphasize that the district had absolutely no concrete plans at this stage of the game, that it hadn’t yet looked at the opportunities or constraints of taking ownership of the project, or even if doing so was legally feasible at this point in the proceedings.” It is noted in the same article that though PG&E said it cannot transfer the license to the dams, the agency said that it can still transfer the dams themselves.

Since the announcement by Secretary Rollins, responses have been covered in the press from Congressmember Huffman, and representatives from PG&E, the Eel Russian Project Authority, Inland Water & Power Commission, Friends of the Eel River, and others. Articles are linked below.

The Two Basin Solution partners continue to move forward toward a continued diversion and a transfer of the water right in cooperation with PG&E.

Connecting Solutions for Groundwater Resilience Wed, May 6 at 10 AM

California’s water system is complex, and so are the challenges it faces. From groundwater overdraft to flooding and ecosystem decline, these issues are deeply interconnected and can’t be solved in isolation. Join Sustainable Conservation on Wednesday, May 6 at 10:00 AM for the second webinar in the Spring 2026 Voices from the Field webinar series as we explore how groundwater recharge and multibenefit land repurposing work in tandem to support long-term groundwater sustainability and climate resilience across California. By storing water underground in wet years and strategically reducing demand on groundwater supplies, these approaches can improve water reliability, reduce flood risk, and restore habitat, building a more resilient future for our communities, agriculture, and environment. The conversation will feature leaders from the California Department of Conservation and Earth Genome to discuss the work currently being done and what it takes to implement these solutions at scale.
