blog post Video: Making the Most of Water for the Environment By Lori Pottinger Sep 8, 2020 Ted Grantham—the first PPIC CalTrout Ecosystem Fellow and a cooperative extension specialist at UC Berkeley—and a panel of experts discuss a new approach to river management that would restore seasonal components of river flow to sustain ecosystem health.
Report A Path Forward for California’s Freshwater Ecosystems By Jeffrey Mount, Brian Gray, Karrigan Bork, James Cloern ... Dec 4, 2019 California’s freshwater ecosystems are under pressure and its aquatic biodiversity is in decline. The state needs a new approach to protect the many beneficial uses these ecosystems provide. This report describes a way to manage the state’s freshwater ecosystems—called “ecosystem-based management”—that can improve conditions for native biodiversity and human uses, and increase resilience to climate change.
blog post Remaking Flood Management to Support Salmon By Lori Pottinger Jul 18, 2018 California’s aquatic ecosystems and the species that depend on them are in trouble. Restoring floodplains can make a big difference.
Report What If California’s Drought Continues? By Ellen Hanak, Jay Lund, Jeffrey Mount, Peter Moyle ... Aug 19, 2015 California is in the fourth year of a severe, hot drought—the kind that is increasingly likely as the climate warms. Although no sector has been untouched, impacts so far have varied greatly, reflecting different levels of drought preparedness. Urban areas are in the best shape, thanks to sustained investments in diversified water portfolios and conservation. Farmers are more vulnerable, but they are also adapting. The greatest vulnerabilities are in some low-income rural communities where wells are running dry and in California’s wetlands, rivers, and forests, where the state’s iconic biodiversity is under extreme threat. Two to three more years of drought will increase challenges in all areas and require continued—and likely increasingly difficult—adaptations. Emergency programs will need to be significantly expanded to get drinking water to rural residents and to prevent major losses of waterbirds and extinctions of numerous native fish species, including most salmon runs. California also needs to start a longer-term effort to build drought resilience in the most vulnerable areas.
blog post Connecting the Drops in Watershed Management By Lori Pottinger Feb 12, 2019 The Yuba Water Agency manages its watershed for hydropower, water supply, flood control, and ecosystem health. We talked to the agency’s manager, Curt Aikens, about lessons learned from this integrated approach.
blog post Video: Improving the Health of California’s Freshwater Ecosystems By Lori Pottinger, Ashlyn Perri Mar 1, 2021 California’s freshwater ecosystems are in poor health, and the current approach for managing them is not working. Jeff Mount, senior fellow at the PPIC Water Policy Center, describes a path for improving their condition to protect the benefits they bring.
Report Making the Most of Water for the Environment: A Functional Flows Approach for California’s Rivers By Ted Grantham, Jeffrey Mount, Sarah Yarnell, Eric D. Stein Aug 24, 2020 Water and land management activities have substantially altered river flows across the state, degrading ecosystems and decimating populations of native species. Restoring seasonal components of river flow is key to sustaining the biological, chemical, and physical processes necessary for ecosystem health.
blog post Commentary: Four Strategies for Managing California’s Crucial Watershed By Ellen Hanak, Greg Gartrell May 23, 2022 California is not doing a good job of tracking changes to the Sacramento–San Joaquin Delta and its watershed. In our recent commentary, we argue that’s making it even tougher to manage the water that is available for the benefit of the state’s communities, economy, and environment.
blog post Managing a Non-Native Delta Ecosystem By Lori Pottinger Sep 16, 2019 The Sacramento–San Joaquin Delta has more non-native species than native ones, and its estuary is the most invaded in the world. We talked to scientist Jim Cloern about this challenge.
blog post Video: What If California’s Drought Continues? By Lori Pottinger Aug 25, 2015 State and local experts told a capacity crowd in Sacramento what they have learned from the drought. They described successes, surprises, and looming challenges if it persists.
