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.”
California needs one and a half times the maximum volume of water in Lake Mead, the largest US reservoir, to end its drought.
A new study by the National Oceanic and Atmospheric Administration says natural occurring climate patterns –not climate change- are the primary drivers of California’s drought.
A Republican- backed drought relief bill for California is headed to the floor of the US House of Representatives for a vote Tuesday. The legislation ignited an hour of debate Monday.
Pollution from abandoned mines in the Sierra Nevada could threaten California's primary water supply.
The City of Roseville hopes to break the 20-percent water conservation mark for the year. The city posted its best conservation mark for the year in November.
