Located on the west side of the San Joaquin Valley in the Coast Range foothills, San Luis Dam and Reservoir are used by the state and federal governments to store water diverted from the Delta. It is the largest offstream reservoir in the United States.
The San Luis Reservoir is a key water facility serving both the State Water Project and the federal Central Valley Project. It can hold 2 million acre-feet of water and is jointly owned by the federal Bureau of Reclamation and California’s Department of Water Resources. The state’s share of the San Luis Reservoir water is 55 percent.
Get a unique view of the San Joaquin Valley’s key dams and reservoirs that store and transport water on our March Central Valley Tour.
Our Central Valley Tour, March 14-16, offers a broad view of water issues in the San Joaquin Valley. In addition to the farms, orchards, critical habitat for threatened bird populations, flood bypasses and a national wildlife refuge, we visit some of California’s major water infrastructure projects.
Come with us as we venture through California’s Central Valley, known as the nation’s breadbasket thanks to an imported supply of surface water and local groundwater. Covering about 20,000 square miles through the heart of the state, the valley provides 25 percent of the nation’s food, including 40 percent of all fruits, nuts and vegetables consumed throughout the country.
Last summer it was a jarring symbol of California’s historic five-year drought. San Luis Reservoir — the vast lake along Highway 152 between Gilroy and Los Banos, the state’s fifth-largest reservoir and a key link in the water supply for millions of people and thousands of acres of Central Valley farmland — was just 10 percent full.
San Luis Reservoir west of Los Banos is on its way to filling for the first time since 2011 as rain and snow bring the state additional relief from a punishing drought. Statewide, a series of storms over the past two weeks have allowed water managers to fill major reservoirs to above-normal levels for this time of year.
Robert Haskins walked across a vast expanse of cracked mud, littered with old beer bottles and millions of tiny clam shells, that in most Augusts would be 50 feet underwater. But the San Luis Reservoir, the vast inland sea along Highway 152 that is a key part of Silicon Valley’s water supply, is only 10 percent full, its lowest level in 27 years.
This 25-minute documentary-style DVD, developed in partnership with the California Department of Water Resources, provides an excellent overview of climate change and how it is already affecting California. The DVD also explains what scientists anticipate in the future related to sea level rise and precipitation/runoff changes and explores the efforts that are underway to plan and adapt to climate.
30-minute DVD that traces the history of the U.S. Bureau of Reclamation and its role in the development of the West. Includes extensive historic footage of farming and the construction of dams and other water projects, and discusses historic and modern day issues.
Water as a renewable resource is depicted in this 18×24 inch poster. Water is renewed again and again by the natural hydrologic cycle where water evaporates, transpires from plants, rises to form clouds, and returns to the earth as precipitation. Excellent for elementary school classroom use.
The 24-page Layperson’s Guide to the Central Valley Project explores the history and development of the federal Central Valley Project (CVP), California’s largest surface water delivery system. In addition to the history of the project, the guide describes the various CVP facilities, CVP operations, the benefits the CVP brought to the state, and the CVP Improvement Act (CVPIA).
This 3-day, 2-night tour travels the length of the San Joaquin Valley, giving participants a clear understanding of the State Water Project and Central Valley Project. Stops include the Kern County Water Bank, the San Joaquin River, Terminus Dam, Mendota Pool, Friant Dam, San Luis National Wildlife Refuge and San Luis Reservoir.
A new look for our most popular product! And it’s the perfect gift for the water wonk in your life.
Our 24×36 inch California Water Map is widely known for being the definitive poster that shows the integral role water plays in the state. On this updated version it is easier to see California’s natural waterways and manmade reservoirs and aqueducts - including federally, state and locally funded projects - the wild and scenic rivers system, and natural lakes. The map features beautiful photos of California’s natural environment, rivers, water projects, wildlife, and urban and agricultural uses and the text focuses on key issues: water supply, water use, water projects, the Delta, wild and scenic rivers and the Colorado River.
