The Eel-Russian Project Authority is a joint powers authority formed by a joint exercise of powers agreement between the County of Sonoma, Sonoma County Water Agency (Sonoma Water) and the Mendocino County Inland Water and Power Commission (MCIWPC). Round Valley Indian Tribes (RVIT) has a seat on the five-member Board of Directors, which is comprised of two representatives from MCIWPC, one from Sonoma Water, one from the County of Sonoma, and one from RVIT.

The Eel-Russian Project Authority is negotiating with the Pacific Gas and Electric Company (PG&E) as the utility moves ahead with plans to surrender operations of the Potter Valley Hydroelectric Project and to decommission the Scott and Cape Horn dams on the Eel River. The Eel-Russian Project Authority will also have the legal capacity to own, construct and operate a new water diversion facility near the Cape Horn Dam.
