Water Stress and a Changing San Joaquin Valley

By Ellen Hanak, Jay Lund, Richard Howitt, Peter Moyle ...

The San Joaquin Valley—California’s largest agricultural region and an important contributor to the nation’s food supply—is facing growing water stress and a number of related environmental and public health problems. Large parts of the valley have become dependent on unsustainable pumping of groundwater. Tackling these linked issues with cooperative, coordinated approaches is key to success.

This research was supported with funding from the S. D. Bechtel, Jr. Foundation, the TomKat Foundation, and the US Environmental Protection Agency.

Policy Priorities for Managing Drought

By Ellen Hanak, Jay Lund, Jeffrey Mount, Peter Moyle ...

State, federal, and local water managers have worked diligently to reduce the economic, social, and environmental harm from the current drought. But as the drought continues, the challenges will grow more acute. California can learn from experiences to date—and from Australia’s response to its Millennium Drought—to better prepare both for the year ahead and for future droughts. State leaders should address weaknesses in four areas of drought preparation and response, by: 1) improving water use information, 2) setting clear goals and priorities for public health and the environment, 3) promoting water conservation and more resilient water supplies, and 4) strengthening environmental management.

New Opportunities for Trading Surface Water in the Sacramento Valley under SGMA

By Alex Ehrens, Joy Collins, Andrew Ayres

Successful groundwater stewardship under the Sustainable Groundwater Management Act (SGMA) demands good information—not only about groundwater conditions, but also about surface water availability. We produced a new dataset of how access to this vital resource varies across irrigated farmland in the Sacramento Valley and the Delta, so it’s now possible to assess surface water conditions across the entire Central Valley.
