Recent storms have pushed the state's snowpack to nearly 150 percent of normal levels.
The Sierra snowpack, which supplies most of the state's water, is 146 percent of normal for this time of year, according to the California Department of Water Resources.
The department will conduct its first official snow survey next week.
Reservoirs across the state have also been replenished by recent storms.
Locally, Donnell's Reservoir is 130 percent of normal, and New Melones is at 118 percent. However, Beardsley and Tulloch reservoirs are only 88 and 74 percent of normal respectively.
The most recent series of storms brought several inches of rain and snow to the Mother Lode, but a break in storms is expected through today and most of Friday.
