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 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:
• 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.
• 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, preconstruction
design work, and engineering work (“Pre-
Construction Work”)
