The Sacramento-San Joaquin Delta (Delta) is a biodiverse ecosystem that covers about 1,150 square miles and supports over 700 species of fish and wildlife. The Delta is an important source of water for the state and is used to convey water from Northern California to Southern California. The Delta faces several significant problems, including: (1) a decline in key native fish species, (2) reductions in the amount of Delta water available for use elsewhere, (3) water pollutants that cause harm to species and increase treatment costs, and (4) levees at significant risk of failure. The state has engaged in numerous efforts to address these problems and achieve its "coequal goals" for the Delta: water supply reliability and ecosystem restoration. There are many opportunities for the Legislature to improve the success of these efforts. We identified several issues for its consideration, including (1) demands for Delta water, (2) uncertain funding sources and slow implementation of some key activities, (3) limits on the effectiveness of governance in the Delta, and (4) challenges to restoring the Delta ecosystem. By addressing some of these issues, the Legislature can improve the likelihood that its goals and objectives for the Delta will be realized.

The Delta of the Sacramento and San Joaquin Rivers is California’s water supply crossroads. It is the major collection point for water that serves more than 25 million people, two-thirds of our State’s population.
The maze of islands and channels at the confluence of these two large rivers has long been the focal point of debate surrounding a number of complicated water-related issues of statewide importance. Agricultural, urban, industrial, environmental, and recreational interests have a vital stake in the Delta and a need to understand the physical Delta and its
This Overview describes the waterways, highways, levees, historic flooding, water supply systems and political boundaries of the Delta to convey a basic understanding of the complexity of the Delta and its significance to the people of California.

The Sacramento-San Joaquin River Delta of California once was a great tidal freshwater marsh blanketed by peat and peaty alluvium. Beginning in the late 1800s, levees were built along the stream channels, and the land thus protected from flooding was drained, cleared, and planted. Although the Delta is now an exceptionally rich agricultural area (over a $500 million crop value in 1993), its unique value is as a source of freshwater for the rest of the State. It is the heart of a massive north-to-south water delivery system. Much of this water is pumped southward for use in the San Joaquin Valley and elsewhere in central and southern California.
The leveed tracts and islands help to protect water-export facilities in the southern Delta from saltwater intrusion by displacing water and maintaining favorable freshwater gradients. However, ongoing subsidence behind the levees reduces levee stability and, thus, threatens to degrade water quality in the massive north-to-south water-transfer system.

Delta science needs to push beyond its tendency to focus on short-term policy mandates and near-term crises. Taking a longer, 50- to 100-year viewpoint has been part of various planning exercises including Delta Vision. That kind of long-range thinking now needs to be more strongly incorporated into the whole Delta science and management endeavor. An appreciation of the changes that are coming, particularly those associated with climate change, needs to inform all our research and planning.
In the meantime, despite management actions that in some instances appear heroic, native fish continue to decline in the Delta. The food web has changed dramatically, new stressors are added daily to existing ones, and several native species are virtually extinct. While we must continue to try to shore up the delta smelt, for example, it is time for serious debate about more radical alternatives to habitat restoration, including assisted relocation, assisted evolution, even perhaps cryopreservation (freezing of genetic materials). Agency mandates based on the past should not prevent us from taking actions that prepare us for a very different future.
The capacity of the Delta to absorb extremes of all kinds is declining. In the future, water managers will have to adjust to reduced and more variable inflows to the Delta and to less predictable sources of water supply. Sustaining a Delta ecosystem hospitable to native species will be much more difficult. In that case, it may become necessary to refocus on managing for novel plant and animal communities that provide desirable ecosystem services. Delaying action until the next crisis is upon us will greatly increase the risk and costs of failure.
