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.”
January brought above-average rainfall and snow to much of California, partly due to El Niño. But forecasters say the ocean warming condition is "taking a break" for the next week or longer.
The U.S. Drought Monitor says, other than a slight reduction in exceptional drought in the northern Sierra, it needs more time to assess impacts of the recent moisture on California's long-term drought.
California regulators have made modest adjustments to water conservation requirements for cities.
The second measurement this winter of snowpack in the Sierra Nevada was 130 percent of average. State water officials say the snowpack will help reservoir recovery.
California's water conservation rate dropped to 18 percent in December. But water regulators say the state continues to meet its long term goals.
