As California works to improve its official accounting of water for a range of purposes, one major area lacking widely accepted quantification is the consumptive use of water for agriculture, particularly evapotranspiration (ET) from crops. In the Sacramento-San Joaquin Delta, such estimates are important, along with other hydrologic flows, for a variety of water rights, […]
Evidence of what scientists are calling the planet’s Sixth Mass Extinction is appearing in San Francisco Bay and its estuary, the largest on the Pacific Coast of North and South America, according to a major new study. So little water is flowing from the rivers that feed the estuary, which includes the Sacramento-San Joaquin River […]
Do you think you could reduce your water use by 40 percent? What if we asked for even more than that? This is the type of rationing we can expect during a severe drought if a new proposal from the State Water Resources Control Board is implemented. The San Francisco Public Utilities Commission is the […]
The contentious struggle to restore threatened fisheries in the San Francisco Bay-Delta and the Central Valley has focused mostly on reducing the amount of water exported from the Sacramento-San Joaquin Delta to farms and Southern California cities. That’s now changed. The State Water Resources Control Board has asked San Francisco and other communities that withdraw […]
California’s major reservoirs are holding 69 percent more water than a year ago, the U.S. government announced Friday, but regulators warned that drought conditions continue to plague the state. In its annual inventory of water in storage, the U.S. Bureau of Reclamation said the six key reservoirs owned by the federal government’s Central Valley Project […]
California’s drought has helped the public see what many researchers have known for a long time: Water and energy are deeply intertwined. Kelly Twomey Sanders has been exploring this energy-water nexus in depth. She joined the Sonny Astani Department of Civil and Environmental Engineering at the University of Southern California in 2014 after having completed […]
