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.”
Record summer heat has increased fire risk in California and the Western U.S. as drought conditions expand.
Statewide water conservation exceeded the mandatory goal in May and Sacramento reduced water use 40 percent.
In the fourth year of drought in California, sales and use of "safe and sane" fireworks are restricted in some areas, allowed in others.
A California Assembly committee will hear a bill Wednesday that would allow water districts to impose taxes on any business, industry or person who wastes water.
The drought can be blamed for a number of problems and the latest is a major decline in the duck population. A new survey shows lack of rain has led to poor habitats.
