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.”
Big businesses in California say they want to be more involved in managing the state’s water supply.

Another dry winter worries California rice farmers who are planning for this year's crop. The state's harvest was down nearly 25 percent last year. And, it's not just water that worries growers.
California’s water supply continues to diminish. The water content in the Sierra snowpack is the worst it’s been this time of year since 1991. Water conservation rates are equally dismal, dropping dramatically in January.
