Project Title: 2021 Temporary Water Transfer
Project Location- Specific: The proposed action would occur in San Joaquin and Stanislaus counties at New Melones Reservoir to the confluence of the Stanislaus River with the San Joaquin River and the Sacramento-San Joaquin Delta, then into the Jones Pumping Plant, and the Delta Mendota Canal for delivery to districts within San Joaquin and Stanislaus Counties.
Project Location – City: N/A Project Location – County: San Joaquin and Stanislaus
Description of Nature, Purpose of Beneficiaries of Project: Up to 7,500 acre-feet (AF) of Stockton East Water District’s (SEWD)’s 2021 allocated CVP water at New Melones Reservoir is to be transferred to the San Luis & Delta Mendota Water Authority (SLDMWA). Under the transfer. SEWD would not take delivery of the 7,500 AF of its 2021 allocated CVP water previously scheduled for diversion from New Melones Reservoir. Rather, the CVP water would be diverted by the United States Bureau of Reclamation (Reclamation) at Jones Pumping Plant for delivery to the Recipients. In lieu of the transferred water, SEWD would use up to 7,500 AF of its previously stored water in New Hogan Reservoir to meet in-district needs. With a 10% carriage loss, the estimated quantity of transfer available for pumping is 6,750 AF.
The buyer is the SLDMWA, which consists of 27 member agencies representing water service contractors and San Joaquin River Exchange Contractors. The SLDMWA service area consists primarily of agricultural lands on the west side of the San Joaquin. The seller is SEWD which provides surface water for both agricultural and urban uses. The delivery of the transferred water is anticipated to take place between August and November 2021. The timing and rate of the water transferred will be closely coordinated between the transfer participants and Reclamation because the water will be released in conjunction with New Melones Central Valley Operation releases. Water made available for transfer to agencies within the SLDMWA will be pumped through the Jones Pumping Plant and would be conveyed through the Delta-Mendota Canal and local irrigation canals to the purchasing agencies. For purposes of this transfer, the purchasing agencies would be limited to those SLDMWA members within San Joaquin and Stanislaus Counties, within the place of use for water from New Melones Reservoir (collectively, the “Recipients”). No water will be moved through state facilities in this effort.
