The Legislative Analyst’s Office told lawmakers that without comprehensive statewide regulation of groundwater, management of the state’s water supply will be increasingly difficult. The LAO suggests the state require local water districts to phase in groundwater permitting and keep track of how much water is extracted from all groundwater wells.
Hydrologist Jay Famiglietti with UC Irvine says in some places water will disappear in a matter of decades.
“The water losses over the past couple of years have been particularly profound," says Famiglietti. "They are roughly equal to 12 and a half cubic kilometers per year which is on annual basis more water than all human water use domestic, municipal, urban water use for all Californians.”
Overall water use decreased again in September compared to last year in the Sacramento region. Water providers are also pumping less groundwater, despite a heavier reliance on it in the drought.
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.
