Supported by $400,000 from the Climate Adaptation and Resiliency Program, a coalition of federal, academic, non-profit and private organizations has developed a modeling tool to enhance climate adaptation and resilience planning in five Sacramento River watersheds. These watersheds provide the vast majority of California’s utilized water and over 80 percent of the freshwater to San Francisco Bay. By estimating the ecological returns of conservation and restoration efforts, the modeling tool will help determine what future actions and investments would best restore and protect the health of this important region.
