Sacramento–San Joaquin River Delta

The San Francisco Bay Area depends on the Delta watershed for 2/3 of its drinking water supply. Sierra Nevada snowmelt and rainfall fills rivers and streams that flow toward the San Francisco Bay. Much of that mountain water flows through the Sacramento-San Joaquin River Delta to communities throughout the Bay Area.

In fact, 40 percent of Santa Clara County's water supply is conveyed through the Delta.

The Delta is an essential feature of our water system. Yet, after decades of alterations, the Delta is far from the natural estuary it once was. The Delta’s 150-year old man-made network of levees is old and fragile.

Without an effective conservation and renewal strategy, the Delta’s sensitive ecosystem and water transport system will continue to deteriorate, threatening the delivery of safe, reliable drinking water to the nearly 1.8 million residents that we serve in Silicon Valley.

The statewide Bay Delta Conservation Plan (BDCP) effort is attempting to achieve water supply reliability and ecosystem restoration for the Delta. To sustain our economy and our way of life, we must find a balanced solution that restores the Delta ecosystem and assures long-term sustainable water supplies.
