Del Puerto Canyon Reservoir

The Del Puerto Canyon Reservoir project, managed by the Del Puerto Water District in California, involves the construction of an 82,000-acre-foot reservoir located west of Patterson and I-5. The primary purpose of the facility is to store water from the Delta-Mendota Canal to support local agriculture and wildlife refuges. The scope of work encompasses the construction of a main dam, saddle dams, a spillway, inlet and outlet works, conveyance and electrical facilities, as well as the relocation of existing utilities and Del Puerto Canyon Road. This project is categorized under NAICS code 237990 and is currently listed as a forecast with a posted date of August 25, 2026. Environmental compliance has been addressed through an Environmental Impact Report, with a Notice of Determination filed with Stanislaus County on August 21, 2026. General Manager Anthea G. Hansen serves as the primary point of contact for this initiative.
