Santa Rosa officials working to boost the city’s backup water supply have tapped into deep fears among residents of a Rincon Valley neighborhood that the installation of an emergency well near their homes might threaten their own water supplies.
The transformation of the western United States by irrigation offers hope for developing countries looking for models to improve their irrigation system for food security or agricultural prosperity. The transformation of the American West from barren desert and low value grazing into one of the largest agriculture areas in the United States would be impossible without irrigation.
Vickie Mulas, a partner in her family’s Sonoma Valley dairy and vineyard operations, is no friend of regulations. … But Mulas, a member of a prominent local ranching family, relishes her role in California’s newest round of rule-making that will — in an unprecedented departure from past practice — put limits on how much water people can pump out of the ground.
A company’s vision to pump water from the Mojave Desert and sell it to thirsty Southern California cities had looked to some to be a long shot. … But a series of developments has invigorated backers of the project, which involves both federal and state jurisdictions.
The Water Education Foundation is well known for its colorful, poster-sized maps that tell the story of our most valuable resource. The California Water Map features natural and manmade water resources throughout the state, including the wild and scenic rivers system, federally funded projects, state-funded projects, locally funded projects and saline or alkaline lakes. It was given a new look in 2016 and remains our most popular item. Hot off the press is our newly updated and revised California Groundwater Map.
California’s historic winter ended the drought in many parts of the state and piled up record levels of snowpack in the Sierra Nevada mountains. With so much precipitation, surface water infrastructure – our network of dams, reservoirs and levees – has been called into action like never before, and in some cases has struggled to handle the influx of flows.
Speakers from the California Department of Water Resources, NASA/JPL, and the U.S. Geological Survey will be on tap at a free briefing Aug. 16 in Fresno, Land Subsidence in the San Joaquin Valley. Land subsidence caused by groundwater pumping has been a problem for decades in the San Joaquin Valley, but an increased reliance on aquifers during the last decade has resulted in subsidence rates in excess of 1 foot per year in some parts of the region.
The Agua Caliente Band of Cahuilla Indians’ 4-year-old legal fight to assert rights to groundwater took a step forward on Wednesday as a federal judge agreed to let the lawsuit proceed while water agencies appeal an earlier ruling to the Supreme Court.
Five companies responsible for polluting the groundwater in the San Gabriel Valley have agreed to continue cleanup for another 10 years, sparing 400,000 residents higher water bills, a state agency announced Thursday.
During droughts, groundwater pumping is increased to make up for losses from surface water. This is especially true in California’s Central Valley, which stretches roughly 400 miles from Redding to just south of Bakersfield, and is the heart of the state’s $47 billion-a-year agricultural industry.
California farmers have long been able to get permits to drill new wells in areas where groundwater levels are falling without publicly saying how much water they intend to pump. That would change under a bill approved this week by the California Senate.
Join us for a special, free briefing on Aug. 16 at Fresno State cosponsored by the California Department of Water Resources and Water Education Foundation that will highlight the array of technologies available for subsidence measurement and monitoring, including information and technical support being provided by DWR.
The Trump administration has shown support for the project, which has been opposed by [U.S. Senator Dianne] Feinstein and several environmental groups that argue the water extraction would harm the fragile desert ecosystem.
Agriculture accounts for roughly 80 percent of the water used by people in California. “Roughly” because, unlike urban water districts, farm-water suppliers reveal little about how much of the state’s most precious resource goes into irrigation ditches and fields.
San Franciscans take pride in drinking pristine water from Hetch Hetchy Reservoir, which they treasure as among the purest in the nation. So a recent move by the Public Utilities Commission to introduce groundwater gradually into the city’s drinking supply prompted anxiety and suspicion.
The State Water Resources Control Board is scheduled to hold a free seminar May 30 that examines the use of stormwater for groundwater recharge. The seminar, called Enhancing Groundwater Recharge with Stormwater, will explore how stormwater is increasingly viewed as an under-utilized resource that could be used to recharge aquifers.
