The Sacramento-San Joaquin Delta is an essential resource for California’s agricultural and urban water users. Rivers that once flowed to the Delta provide almost half of the water used for California’s agricultural water supply, and more than half of Californians rely on water conveyed through the Delta for at least some of their water supply. This report finds that the reduction of groundwater overdraft and water withdrawals from the Delta can have a positive impact on the surrounding ecosystems, as well as the sustainability and resilience of California’s water supplies.
