In the second of two Delta Conveyance Deep Dive episodes on seismic risks in the Sacramento-San Joaquin Delta, we hear from two of California's leading seismology experts about the vulnerability of the Delta to a major seismic event.

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 fresh, clean 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 proposed 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 as snowpack, 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 750,000 acres of farmland. The infrastructure that enables conveyance for 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?
Because the SWP relies on the Delta’s natural channels to convey water, it is vulnerable to earthquakes and sea level rise. Upgrading SWP infrastructure protects against these threats and secures the longevity of the SWP and the future reliability of SWP water supplies. The purpose of the proposed Delta Conveyance Project is to modernize the aging SWP infrastructure in the Delta to restore and protect the reliability of SWP water deliveries in a cost-effective manner, consistent with the State’s Water Resilience Portfolio. And in doing so, allow DWR to address sea level rise and climate change, minimize water supply disruption due to seismic risk and provide operational flexibility to improve aquatic conditions in the Delta.
