On May 2, 2019 the Department of Water Resources (DWR) announced that it will pursue a new environmental review and planning process for modernized water conveyance in the Delta.
There is clear evidence of the vulnerabilities in the Sacramento-San Joaquin Delta (Delta) posed by climate change and earthquake risk. As sea levels continue to rise, the Delta will be faced with increasing water levels and salinity, which will dramatically alter and harm water quality and supply locally and for 27 million Californians across the state. Immediate action is needed to upgrade Delta infrastructure, ensuring the state’s largest supply of clean water is climate resilient and able to respond to these risks.
As directed by the Governor and building on work already conducted, the Department of Water Resources is pursuing a new environmental review and planning process for a single tunnel solution to modernize Delta conveyance. This fresh approach is consistent with the Governor’s recent executive order directing state agencies to develop a portfolio of statewide water actions and investments. Modernizing Delta conveyance paired with complementary projects that improve water recycling, recharge depleted groundwater reserves, strengthen existing levee protections and improve Delta water quality, is critical to building a resilient water supply for California’s communities and economy.
The success of the state’s Water Resilience Portfolio, and of water infrastructure upgrades, relies on a strong partnership with stakeholders. The state is committed to community and public engagement as this new process moves forward.
Information regarding schedule, opportunities for public review and other announcements and updates will be posted on this page, as available.
Delta Conveyance Updates
The status quo in the Delta is not an option and puts the state’s clean water supply at risk.
Following Governor Newsom’s recent direction, DWR is pursuing a new environmental review and planning process for a single tunnel solution to modernize water infrastructure in the Delta.
Rain and snowmelt from the Sierra Nevada flows through the Sacramento-San Joaquin Bay Delta and supplies drinking water—through the State Water Project (SWP)—to 27 million people. Yet the reliability of this critical water supply is compromised.
