Climate Change Risk Faced by the California Central Valley Water Resource System



California Department of Water Resources (DWR)




This study, undertaken for California's 4th Climate Change Assessment, presents a methodology that improves on previous approaches of assessing the impact of climate change on water resource management. The authors reveal fundamental climate change risks and specific vulnerabilities of one of the State's key water resource systems — the integrated California Central Valley System (CCVS). By using a bottom-up decision scaling approach and evaluating a comprehensive range of data on climate variability and river flows, the study provides projecitons and discussion of specific and critical future performance metrics for CCVS in the year 2050.
