California’s Delta-Groundwater Nexus: Economic and Water Supply Effects of Ending Groundwater Overdraft in California’s Central Valley

Several researches from the Department of Civil and Environmental Engineering at the University of California, Davis have recently published an article on the nexus between California’s Delta and groundwater.

The paper examines the economic and water management effects of ending long-term overdraft in California’s Central Valley, the state’s largest aquifer system. These effects include changes in regional and statewide surface water diversions, groundwater pumping, groundwater recharge, water scarcity, and resulting operating and water scarcity costs.

Missing the boat on freshwater fish conservation in California

“Population growth and increasing water-use pressures threaten California's freshwater ecosystems and have led many native fishes to the brink of extinction.”

Watershed Researchers present at California Water and Environmental Modeling Forum

Several researchers from the Center will be participating and presenting at the California Water and Environmental Modeling Forum, a non-profit, non-partisan organization whose mission is to increase the usefulness of models for analyzing California’s water-related problems.

Jay Lund elected American Society of Civil Engineers Distinguished Member

Professor Jay Lund has been elected to the grade of Distinguished Fellow in the American Society Civil Engineers. He is one of only nine Distinguished Members inducted this year.

April 4-5: Weathering Change: Impact of Climate Change and SGMA on CA Water Conference

Can California adapt to the challenges of climate change? How will the Sustainable Groundwater Management Act (SGMA) influence water availability and allocation in California? What is the best path moving forward? These are all questions that will be answered in the Weathering Change: The Impact of Climate and the Sustainable Groundwater Management Act on California’s Water Conference.

Project Nigiri Celebrates Five Years on the Floodplain

Project Nigiri began as an investigation to using harvested rice fields as potential salmon nurseries that could help boost struggling Central Valley populations. The project takes its name after a Japanese form of sushi that has a slice of fish atop a compressed wedge of vinegared rice.
