![]() This chart is found in California Drought: Farm and Food Impacts on the ERS website, February 2016. Farms in Southern California receive much of their surface water from the Colorado River, which has not been as heavily impacted by the current drought. While surface water from these projects is delivered through much of the State, the impacts of these reductions are most pronounced in the Central Valley of California. In an historical context, the current drought is at least as bad, from a deliveries perspective, as the 19-1992 droughts. Relative to longrun averages, deliveries from both projects were down modestly in 20, and then dropped dramatically in 2014, with similar delivery shortfalls for 2015. ![]() We operate and maintain the State Water Project and support sustainable groundwater management.

The water stored beneath our feet is an important water supply source in California. In contrast, the Central Valley Project, managed by the U.S. Gavin Newsom ’s office renewed its commitment on Wednesday to launching California’s biggest water project in half a. On average, 70 percent of annual State Water Project supplies go to urban users and 30 percent to agricultural users. Surface-water imports via the California Aqueduct in the late 1960s and early 1970s, and the associated decrease in groundwater pumping, resulted in a steady. The two largest overarching mechanisms for delivering surface water in California are the State Water Project (SWP) and the Federal Central Valley Project (CVP). California agriculture relies heavily on irrigation, and much of the irrigation water is supplied by large-scale State and Federal water projects that store, transport, and deliver water across hundreds of miles. In California, measures of exposure to local water shortages are only part of how the drought is affecting farms. Source: United States Department of Interior, Bureau of. California is now entering the fifth year of a major drought, and by many measures, 20 have been the worst years of the drought for California agriculture.
