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.”
As the forecast for a wet December improves, a new study says only so much water can be stored by future dam or reservoir projects in California.
The National Weather Service is offering a more positive forecast for the likelihood of a wet December in California.
(AP) - Officials say residents of a California community where hundreds of home wells have run dry can now take hot showers in portable facilities set up in a church parking lot.
The U.S. Drought Monitor measures the impact of the drought across the nation and California cattle ranchers have millions of dollars at stake based on that information. But some are questioning the accuracy of the data.
The drought has caused contamination and the closure of some groundwater wells at South Lake Tahoe.
