Document Description
On December 21, 2023, DWR certified the environmental impact report (“EIR”) for, and approved, the Delta Conveyance Project (State Clearinghouse No. 2020010227). The Delta Conveyance Project consists of pre-construction activities (discussed below) and the construction, operation, and maintenance of new State Water Project (“SWP”) water diversion and conveyance facilities in the Delta that would be operated in coordination with existing SWP facilities. The Delta Conveyance Project includes the following key components and actions: • Efforts to identify geotechnical, hydrogeologic, agronomic, and other field conditions that will guide appropriate construction methods and monitoring programs for final engineering design and construction data collection and field work investigations, including ground-disturbing geotechnical work, water quality and hydrogeologic investigations, agronomic testing, the installation of monitoring equipment, construction test projects, pre-construction design work, and engineering work (“Pre-Construction Work”) • Two intake facilities along the Sacramento River in the north Delta near the community of Hood with on-bank intake structures that would include fish screens. • A concrete-lined tunnel, and associated vertical tunnel shafts, to convey flow from the intakes about 45 miles to the south of the Bethany Reservoir Pumping Plant and Surge Basin at a location south of the existing SWP Clifton Court Forebay. • A Bethany Reservoir Pumping Plant to lift the water from inside the tunnel below ground into the Bethany Reservoir Aqueduct for conveyance to the Bethany Reservoir Discharge Structure and into the existing Bethany Reservoir. • Other ancillary facilities to support construction and operation of the conveyance facilities including, but not limited to, access roads, concrete batch plants, fuel stations, and power transmission and/or distribution lines. The Agency, as a responsible agency, has issued a limited approval relating to additional funding for Pre-Construction Work for the Delta Conveyance Project. Apart from funding for the Pre-Construction Work, the Agency has not issued any other approval for the Delta Conveyance Project.
