Document Description
DPWD in partnership with the San Joaquin River Exchange Contractors Water Authority proposes to construct a 85,000-acre-foot reservoir in Del Puerto Canyon west of Patterson and 1-5. Water would be conveyed from the Delta-Mendota Canal (DMC) and stored in the reservoir and could be discharged either back to the DMC, or possibly in the future to the California Aqueduct. Water would serve agriculture and potentially environmental purposes, such as wildlife refuges. The project includes construction of a main dam, four saddle dams, a spillway, inlet/outlet works, conveyance facilities (DMC diversion facility, pumping plant, pipeline and appurtenant components) and electrical facilities (power supply line and substation). The project includes relocating Del Puerto Canyon Road a existing utilities that run through the reservoir site.
