Napa County has work to do to get Napa Valley wine country groundwater supplies in balance for the long haul.   Groundwater pumping in 2021-22 was 18,790 acre-feet, according to a new report. It was the third consecutive year that pumping exceeded the Napa Valley sub-basin’s sustainable yield of 15,000 acre-feet, coinciding with a three-year drought. […]

How California Could Save Up Its Rain Water to Ease Future Droughts

By Andrew Fisher, Resilience. January 15, 2023 Instead of watching epic atmospheric river rainfall drain into the Pacific. California has seen so much rain over the past few weeks that farm fields are inundated and normally dry creeks and drainage ditches have become torrents of water racing toward the ocean. Yet, most of the state remains in severe drought. […]

By Janny Choy and Geoff McGhee Groundwater is back in the spotlight. Largely invisible, lightly regulated and used by 85% of California’s population and much of the state’s $45 billion agriculture industry, groundwater is a crucial reserve that helps stave off catastrophe during drought periods like we’ve experienced over the past three years. Unheralded, Underregulated and Overused, […]

SmartWaterMagazine.com reports that as climate change increases extreme weather events, such as megadroughts, groundwater management is key for sustaining water supply. But current monitoring tools are either costly or insufficient for deeper aquifers, limiting our ability to monitor and practice sustainable management. Now, a new paper bridges seismology and hydrology with an application that uses seismometers […]

Vacaville, California city limit sign.

A lawsuit accusing Vacaville of endangering its residents with tap water polluted with hexavalent chromium — the cancer-causing chemical made infamous in the film “Erin Brockovich” — was dismissed Friday by a federal appeals court, which said the city merely carried the water in its pipes and isn’t responsible for contamination caused by others. The city was […]

California’s farmers are pumping vast amounts of water from underground aquifers this year to make up for water they can’t get from rivers. It’s unsustainable, and the state is moving to stop it.July 23, 2021
The next time you pick up some California-grown carrots or melons in the grocery store, consider the curious, contested odyssey of the water that fed them. Chances are, farmers pumped that water from underground aquifers […]

June 28, 2021 Written by Communications Intern Sage Bachman As California enters another severe drought, residents are once again being asked to use water more judiciously so as to make it last longer. While it is indeed crucial for all of us to reduce our water usage, is also critical to investigate how California’s limited sources […]

The highly engineered rivers that sustain California cities and farms upset streamside woodlands’ relationship with groundwater, a new study finds, jeopardizing their future in a changing climate.

California’s perennially drought-parched Central Valley bears little resemblance to the vibrant landscape of the pre-Gold Rush days, when wild rivers sustained lush woodlands and floodplains teeming with life.

Trees at the center of these biodiversity hotspots evolved in an arid landscape sculpted by finely tuned exchanges […]

The Biden-Harris transition team identified COVID-19, economic recovery, racial equity and climate change as its top priorities. Rivers are the through-line linking all of them. The fact is, healthy rivers can no longer be separated into the “nice-to-have” column of environmental progress. Rivers and streams provide more than 60 percent of our drinking water—and a clear path toward public health, a strong economy, a more just society and greater […]

Subsidence, ground sinking

When humans over-exploit underground water supplies, the ground collapses like a huge empty water bottle. It’s called subsidence, and it could affect 1.6 billion people by 2040. But scientists haven’t modeled global risks of subsidence—until now. To build their model, Sneed and her colleagues scoured the existing literature on land subsidence in 200 locations worldwide. They considered […]
