Creating a Place for Nature in the San Joaquin Valley

By Lori Pottinger

The quest for groundwater sustainability will result in large amounts of irrigated farmland being retired in the San Joaquin Valley. We talked to Scott Butterfield of The Nature Conservancy about how some of these lands could be restored to natural areas that bring multiple benefits.

Drought Watch: A Better Way to Manage Water for Fish

By Ellen Hanak, Jeffrey Mount

This is part of a continuing series on the impact of the drought.

As California’s drought wears on, state and federal regulators will be under increasing pressure to loosen environmental standards that protect native fish and other wildlife.

Safeguarding the Future of California’s Freshwater Ecosystems

By Sarah Bardeen

Climate change is transforming California’s ecosystems, threatening vital habitat for many native species. Some species may be lost, which is why former Department of Water Resources lead scientist Ted Sommer and environmental law expert Jennifer Harder are joining forces as our 2023–24 PPIC CalTrout ecosystem fellows. We recently asked them to tell us more about their new project, which could help protect wildlife as the climate changes.

A Water Budget for the Environment

By Jeffrey Mount

California’s freshwater ecosystems are in decline and becoming increasingly vulnerable to drought. Allocating water budgets for the environment would help.

Policy Brief: Tracking Where Water Goes in a Changing Sacramento–San Joaquin Delta

By Greg Gartrell, Jeffrey Mount, Ellen Hanak

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.

Commentary: Newsom’s Water Strategy Needs to Go a Step Further

By Sarah Null, Jeffrey Mount

Dams are essential to managing California’s water supply, but their construction and operation has harmed freshwater ecosystems. We propose a novel approach to water management that treats the environment as a priority rather than a constraint on reservoir operations—and that may help to manage growing threats to the health of our rivers and estuaries.

Integrated Management of Delta Stressors: Institutional and Legal Options

By Ellen Hanak, Jay Lund, Jeffrey Mount, Brian Gray

Despite some recent progress, the current institutional landscape for regulation and management of stressors in the in the Sacramento–San Joaquin Delta is highly fragmented. A modest but powerful set of institutional changes can help produce better environmental outcomes while containing management costs—which are likely to exceed several hundred million dollars annually. This report lays out proposals for institutional reform.

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.

Costs of Ecosystem Management Actions for the Sacramento–San Joaquin Delta (Medellín-Azuara et al. 2013) assesses costs of water management actions.

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.
