Policy Brief: Storing Water for the Environment

By Sarah Null, Jeffrey Mount, Brian Gray, Kristen Dybala ...

To protect and restore California’s freshwater ecosystems and respond to the changing climate, California’s water managers must change how they operate reservoirs. Our policy brief offers recommendations for how to do this in a way that makes the most efficient use of scarce water for the environment while minimizing impacts on other water uses.

What If California’s Drought Continues?

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

California is in the fourth year of a severe, hot drought—the kind that is increasingly likely as the climate warms. Although no sector has been untouched, impacts so far have varied greatly, reflecting different levels of drought preparedness. Urban areas are in the best shape, thanks to sustained investments in diversified water portfolios and conservation. Farmers are more vulnerable, but they are also adapting. The greatest vulnerabilities are in some low-income rural communities where wells are running dry and in California’s wetlands, rivers, and forests, where the state’s iconic biodiversity is under extreme threat. Two to three more years of drought will increase challenges in all areas and require continued—and likely increasingly difficult—adaptations. Emergency programs will need to be significantly expanded to get drinking water to rural residents and to prevent major losses of waterbirds and extinctions of numerous native fish species, including most salmon runs. California also needs to start a longer-term effort to build drought resilience in the most vulnerable areas.

Stewarding California’s Wet Years

California has made great strides in preparing for a drier, hotter future, but it remains a challenge to harness the bounty of wet years while also reducing flood risk. How did California’s water sector manage the unusually wet conditions of the 2023 water year—and what lessons can we glean for the future? We speak with three panels of experts to find out.
