The powerful storms that soaked Northern California over the past week did more than trigger power outages, mudslides and flash floods.

They sent roughly 350 billion gallons of water pouring into California’s biggest reservoirs — boosting their storage to levels not seen in years, forcing dam operators to release water to reduce flood risks and all but ending the five-year drought across much of Northern California, even though it remains in the south, experts said Monday.

“California is a dry state and probably always will be in most years, but we certainly don’t have a statewide drought right now,” said Jay Lund, a professor of engineering and director of the Center for Watershed Sciences at UC Davis.

“We have to be careful about crying wolf here,” he said. “You have to maintain credibility with the public when there are critically dry years, so you have to call it like it is when conditions improve.”

On Monday much of the state began drying out from the weekend drenching that caused at least three fatalities and triggered flooding in Morgan Hill, Sonoma County, Yosemite and parts of the Sacramento Valley, even as forecasters said another storm system was coming in Tuesday.
