By Ellen Hanak, Greg Gartrell

By Greg Gartrell, Jeffrey Mount, Ellen Hanak

The Sacramento–San Joaquin Delta supplies water to roughly 30 million Californians, over 6 million acres of farmland, and countless ecosystems. But the watershed’s climate is changing: recent decades have seen record warmth, higher evaporation, and declining snowpack. We track where the water is going—and how to adapt.
