What is Delta conveyance?
Delta conveyance refers to State Water Project (SWP) infrastructure in the vast network of waterways comprising the Sacramento-San Joaquin Delta (Delta) that collects and moves high-quality, clean, safe and affordable water to homes, farms and businesses throughout major regions of the state from the Bay Area to Southern California. The Department of Water Resources (DWR) is the owner and operator of the SWP and is responsible for all associated upgrades and maintenance, including the Delta Conveyance Project that will modernize this water transport infrastructure in the Delta.

Why is Delta conveyance important?
The Delta is at the center of California’s vital water distribution system. Two-thirds of California’s water originates in the Sierra Nevada mountains. eventually flowing through the Delta, where, consistent with water rights, including applicable water quality requirements, it is delivered to more than 27 million Californians and about 750,000 acres of farmland. The infrastructure that enables conveyance of California’s primary water supply is critical to the health of local communities and the success of our state’s economy.
Why is this project needed?
California faces a future of water instability, more rain, less snow, and more frequent extreme events like drought and flood. These changes will reduce the ability of the SWP’s current infrastructure to capture water, especially because there will be less snow and snowmelt available.
The Delta Conveyance Project is an essential climate adaptation strategy. It protects against future water supply losses caused by climate change, sea level rise, and earthquakes. It also helps ensure that the SWP can capture, move and store water to make the most of big, but infrequent, storm events.

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 ...
