California is at a critical juncture on policy for the Sacramento-San Joaquin Delta. This report summarizes the results of a wide-ranging study of cost-effective ways to improve the health of the Delta ecosystem. It highlights the need for science-based, integrated management of the many sources of ecosystem stress. The report also recommends improvements to the highly fragmented system of oversight that now involves dozens of federal, state, and local agencies.

This research was supported with funding from the S. D. Bechtel, Jr. Foundation.
