The report from UC Irvine’s Center for Hydrologic Modeling is an update to a 2011 study which showed the basins lost nearly as much water as the volume of Lake Mead over a seven year period.
The new report finds water storage in the last two years continues to plummet, and the study doesn’t even include the most recent dry winter.
Report author Jay Famiglietti says the amount of water lost is equal to the water used by all of California’s urban areas each year. Most of the loss is due to groundwater withdrawals.
Famiglietti says groundwater levels drop faster during drought than they can be replenished during wet periods.
“This is a worse than ever situation," says Famiglietti. "So we really have to watch what’s going to happen with the groundwater. It’s been bad in the past during drought periods and now with a zero surface water allocation I’m quite concerned that it will be terrible in the future.”
Improved drought conditions and more renewables lead to decrease in natural gas use this summer.
Californians' water use kept creeping back up in July after the lifting of mandatory statewide conservation orders for the drought.
A new study shows fire-fighting foam containing highly fluorinated chemicals is contaminating drinking water supplies around many of the nation's military bases, airports and industrial sites.
It has been a busy fire season across California. But there are fewer fires in the state’s 18 U.S. national forests so far this year, compared to 2015.
Update 8:00 p.m. Sunday: Crews are making "good progress" on the Cold Fire in Yolo County, now at 60% containment. In Monterey County, the Soberanes Fire remains at 45% containment with wind creating an additional challenge for firefighters.
