The San Gorgonio Pass Water Agency Act was passed in 1961 by the California State Legislature. The Act created the Agency and defined its powers. The Agency’s service area of approximately 225 square miles is located in Riverside County and extends from Calimesa to Cabazon. The service area includes the incorporated cities of Calimesa, Beaumont, and Banning, and the communities of Cherry Valley, Cabazon, and the Banning Bench.
The Agency, one of 29 State Water Contractors, purchases water from the State of California and sells it to local retail water agencies. Water is imported into the service area by the California Aqueduct. Click here to learn more about the State Water Project. The final link of the State Water Project to the Pass region, the East Branch Extension, was completed in 2003. Phase 2 of the East Branch Extension is expected to be completed by 2017. Phase 2 will bring the capacity of the Extension to 17,300 acre-feet, which is the Agency’s official allotment of State Project Water. 17,300 acre-feet of water is enough to supply approximately 35,000 families each year.
