The California State Water Project has contracted to sell 4.2 million acre-feet of water per year. But, the annual dependable project yield is only about 2.4 million acre-feet. And the demand is growing rapidly, with the population in the SWP service areas expanding by more than 400,000 people each year. At the same time, more water is being requested for fish and wildlife purposes and more stringent water quality requirements are being imposed, which could require more water. This paper presents a discussion of the needs, and the options for future water supplies, which are under study by the California Department of Water Resources. These options include conventional dams and reservoirs, improved conveyance systems, conjunctive use of surface and ground water and water banking. Efforts to reduce demands by water conservation and greater reuse of reclaimed water are being pursued.
