Overview
Robles Diversion Dam diverts water from the Ventura River into Casitas during the rainy season, December through February. A conduit system conveys Casitas water for 36 miles to populated areas in Ventura County. Casitas is operated by the Ventura River Municipal Water District under a permanent contract with the Bureau of Reclamation.
Casitas Reservoir is a part of the Bureau of Reclamation's Ventura River development project; in addition to Casitas Reservoir, the project includes Robles Diversion Dam, Robles Casitas Canal and a conduit system. Casitas Dam, completed in 1958, is in Coyote Creek, a tributary to the Ventura River. The storage capacity is 250,000 acre-feet covering 2,700 acres and it receives inflow from both the Ventura River and Coyote Creek watersheds.
