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.”
If a flood were to hit Twitchell Island in the Sacramento-San Joaquin Delta it would threaten much of California’s water supply. It’s why emergency management agencies are holding flood-fighting exercises during a drought.
UC Davis researchers have identified 'high priority' dams in California where releasing water may be a key for the survival of native fish species.
California Governor Jerry Brown says the state can lead the way with its water policies just as California is leading the way with initiatives for renewable energy and climate change.
A winter forecast from NOAA's Climate Prediction Center Thursday shows the California drought may persist or intensify in parts of the state.
The Center for Biological Diversity filed notice of intent to sue the U.S. Fish and Wildlife Service Tuesday for not responding to a petition to protect 16 amphibian and reptile species in California
