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.”
When it comes to rain and snow most of California is running below average this year, and little is forecast in the near future.
If you spent time on the water at Lake Tahoe last year and thought it looked a lot cloudier, you're right. UC Davis researchers say extreme weather — drought followed by heavy rains — caused clarity in 2017 to drop to its lowest recorded level.
(AP) — Despite dry conditions in much of the state, water managers say it's too early for fears that California is sliding back into drought as abruptly as the state fell out of it.
Caltrans is worried about the possibility of dead trees falling onto some California highways. The agency has already removed 107,000 trees. Now the agency is getting ready to remove another 54,000 trees, including some on private land.
Sacramento city council voted in favor of a proposal that makes some drought watering restrictions permanent.
