The Sacramento-San Joaquin Delta moves water from Northern California watersheds to farmlands and cities south and west of the Delta. Recent water exports from the Delta have ranged from 5 to 6 million acre-feet per year, supplying much of the water used in the Bay Area, the southern Central Valley, and Southern California. This chapter discusses the state and regional use of Delta water supplies, strategies to manage water exports from the Delta, and some key economic and environmental considerations. It also describes four water export approaches: continue pumping exports through the Delta; divert water upstream and convey it around the Delta through a peripheral canal; combine the current through-Delta pumping strategy with a peripheral canal (so-called “dual conveyance” or “dual facility”); and end exports altogether.Less

An ecosystem in freefall, a shrinking water supply for cities and agriculture, an antiquated network of failure-prone levees—this is the Sacramento-San Joaquin Delta, the major hub of California's water system. This analysis of the latest data evaluates proposed solutions to the Delta's myriad problems. Through in-depth economic and ecological analysis, the chapters find that the current policy of channeling water exports through the Delta is not sustainable for any interest. Employing a peripheral canal—conveying water around the Delta instead of through it—as part of a larger habitat and water management plan appears to be the best strategy for maintaining both a high-quality water supply and at the same time improve conditions for native fish and wildlife. This assessment includes integrated analysis of long term ecosystem and water management options and demonstrates how issues such as climate change and sustainability will shape the future.Less
