Report Envisioning Futures for the Sacramento-San Joaquin Delta By Ellen Hanak, Jay Lund, William Fleenor, Jeffrey Mount ... Feb 7, 2007 California’s Sacramento-San Joaquin Delta is widely perceived to be in crisis today: its levee system is fragile, many of its native species are declining rapidly, and it lacks strong governing institutions to deal with its problems. In its current state, the Delta is unsustainable for almost all stakeholders. This report provides a comprehensive, scientifically up-to-date analysis and outlines several alternative management strategies for the Delta. To view individual chapters, click on the links below.

Report Comparing Futures for the Sacramento-San Joaquin Delta By Ellen Hanak, Jay Lund, William Fleenor, Jeffrey Mount ... Jul 17, 2008 For over 50 years, California has been pumping water through the Sacramento-San Joaquin Delta for extensive urban and agricultural uses around the state. Today, the Delta is ailing and in urgent need of a new management strategy. This report concludes that building a peripheral canal to carry water around the Delta is the most promising way to balance two critical policy goals: reviving a threatened ecosystem and ensuring a reliable, high-quality water supply for California.
Report California’s Water: The Sacramento-San Joaquin Delta By Ellen Hanak, Jay Lund, Jeffrey Mount, Peter Moyle ... Nov 12, 2018 The Delta is the deteriorating, fragile hub of California’s water supply system. Critical decisions about its future are pending. This brief looks at various approaches being proposed to improve management and health of the Delta.
Policy Brief Policy Brief: Tracking Where Water Goes in a Changing Sacramento–San Joaquin Delta By Greg Gartrell, Jeffrey Mount, Ellen Hanak May 16, 2022 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.
Report Aquatic Ecosystem Stressors in the Sacramento-San Joaquin Delta By Ellen Hanak, Jay Lund, William Fleenor, Jeffrey Mount ... Jun 14, 2012 This report looks at five broad categories of stressors on the Delta’s native fishes, examining causes of stress, allocations of responsibility, and options for management. This research was supported with funding from the S. D. Bechtel, Jr. Foundation. Several companion reports contain related findings: Costs of Ecosystem Management Actions for the Sacramento–San Joaquin Delta (Medellín-Azuara et al. 2013) assesses costs of water management actions. Integrated Management of Delta Stressors: Institutional and Legal Options (Gray et al. 2013) lays out proposals for institutional reform of science, management, and regulation. Scientist and Stakeholder Views on the Delta Ecosystem (Hanak et al. 2013) presents detailed results of the two surveys conducted by the report’s authors. Stress Relief: Prescriptions for a Healthier Delta Ecosystem (Hanak et al. 2013) summarizes the overall research project and the recommendations it generated. Where the Wild Things Aren’t: Making the Delta a Better Place for Native Species (Moyle et al. 2012) outlines a realistic long-term vision for achieving a healthier ecosystem.
Report A New Approach to Accounting for Environmental Water: Insights from the Sacramento–San Joaquin Delta By Greg Gartrell, Jeffrey Mount, Ellen Hanak, Brian Gray Nov 12, 2017 How water is apportioned to California’s cities, farms, and the environment can lead to conflict and competition in times of drought. Allocation of water to the environment in particular is poorly accounted for and poorly understood—shortcomings that can affect water policy, decision making, and public perception. This report reviews the state’s long-standing methods for defining and accounting for environmental water and proposes reforms to improve the timeliness, transparency, and detail in the accounting of environmental water allocation.
Report Costs of Ecosystem Management Actions for the Sacramento-San Joaquin Delta By Josué Medellín-Azuara, John Durand, William Fleenor, Ellen Hanak ... Apr 28, 2013 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. Several companion reports contain related findings: Aquatic Ecosystem Stressors in the Sacramento–San Joaquin Delta (Mount et al. 2012) summarizes the science of Delta ecosystem stressors for a policymaking audience. Integrated Management of Delta Stressors: Institutional and Legal Options (Gray et al. 2013) lays out proposals for institutional reform of science, management, and regulation. Scientist and Stakeholder Views on the Delta Ecosystem (Hanak et al. 2013) presents detailed results of the two surveys conducted by the report’s authors. Stress Relief: Prescriptions for a Healthier Delta Ecosystem (Hanak et al. 2013) summarizes the overall research project and the recommendations it generated.
