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.”
The City of Sacramento Department of Utilities reports Friday that city water customers saved more than one-billion gallons of water last month.
California's economy will see modest growth in 2015, with jobs in home building being a bright spot, and the drought having slight impact, according to the latest University of the Pacific's latest Business Forecast.
It appears messages about the need for water conservation are beginning to get through to Californians.
There’s been a drilling frenzy for water in the San Joaquin Valley during the drought. And it’s evident in the number of well permits issued by eight Central Valley counties. Capital Public Radio obtained the data from each county.
(AP) — The 6.0-magnitude earthquake in Northern California on August 24 is credited for shaking loose at least 200,000 gallons of groundwater a day, filling dry creek beds and parched streams.
