Del Puerto Canyon Reservoir Project

Project Overview

Located on Del Puerto Creek in the foothills of the Coast Range mountains west of Patterson, California, the proposed Del Puerto Canyon Reservoir (DPCR) will provide additional off-stream storage on the order of 85,000 acre-feet for the westside of California’s Central Valley. This area has experienced extreme volatility in its water supplies due to hydrologic and regulatory restrictions related to the delivery of water supplies south of the Sacramento-San Joaquin Delta.

The reservoir would tie-into existing conveyance facilities, including the Federal Central Valley Project’s Delta-Mendota Canal and, potentially, the State Water Project’s California Aqueduct.
