Delta Conveyance Updates

When a magnitude 4.2 earthquake struck near Isleton in the Sacramento-San Joaquin River Delta on October 18, it was a reminder of the threat posed to critical State Water Project infrastructure by seismic activity.

The State Water Project (SWP) moves life-sustaining water across the state for 27 million Californians and 750,000 acres of farmland. It supplies families, businesses, crops, and industries with safe and affordable water. Without modernization of our infrastructure, climate-driven weather extremes and seismic threats will affect how we can deliver ...

The proposed Delta Conveyance Project, by adding intakes in the northern Delta and an earthquake resilient tunnel, provides some insurance against water supply disruption from an earthquake in the Bay Area or Delta.

The series of atmospheric river storms that brought record-breaking amounts of rain and snow this year has many Californians asking if our existing water infrastructure is able to capture and store flows from these extreme weather events.

The proposed Delta Conveyance Project would help ensure water supply reliability for the State Water Project in light of projected future changes in precipitation and seasonal flow patterns due to climate change.

DWR today released the Draft Environment Impact Report (Draft EIR) for the Delta Conveyance Project, marking an important step in evaluating a key strategy to adapt to a changing climate and provide clean, reliable water for future generations.

Modernizing how California moves water supplies across the Sacramento-San Joaquin Delta can’t be done by repeating the past.

Preventing fish from getting caught up in the water diverted at the intakes - a situation known as “entrainment” - is a high priority and many innovative technologies have been developed to meet the challenge.

California is immersed in a third year of drought, with January, February and March of 2022 experiencing the lowest precipitation on record. Weather whiplash of big storms followed by dry spells makes every drop of rain, every flake of snow, and every water molecule vital this year for families, farms, the environment and the economy.

The upcoming year will mark an important milestone in the proposed Delta Conveyance Project planning process, with the anticipated release of the Draft Environmental Impact Report (EIR) for public review and comment in mid-2022.
