But this year's abundant Sierra snowpack also poses a severe risk of renewed flooding to parts of California, especially the lower San Joaquin Valley, during the spring thaw, according to state Department of Water Resources (DWR) officials.
More widely, however, electronic readings from 130 snow sensors throughout California showed the statewide snowpack's water equivalent at 61.1 inches, or 237% of average, tying the record statewide average level set in April of 1952.
"This year's result will go down as one of the largest snowpack years on record in California," said Sean de Guzman, manager of the DWR snow survey8 and water supply forecasting unit.
Guzman said California's reservoirs, severely drained just months ago, have all been replenished to more than 100% of average statewide.
Long-term drought conditions in the Colorado River watershed will continue to impact millions of residents of Southern California residents, the DWR said.
