Ellen Hanak, Jay Lund, William Fleenor, Jeffrey Mount, Peter Moyle, William Bennett, and John Durand

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 (Medell-n-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.
