While storms have tapered off in recent weeks, the state Department of Water Resources says the amount of snow remaining should be enough to fill the reservoirs that feed the state's water system.
The department's fourth snow survey of the season on Wednesday found the snowpack was 105 percent of normal for this time of year in the northern part of the Sierra and 103 percent of normal for the southern part of the range. It was 89 percent of average in the central Sierra.
The snowpack was less than half its normal depth at the same time last year. That sparse winter snowfall left Northern California reservoirs depleted to between 40 percent and 60 percent of their capacity.
The additional snow this winter will not be enough to significantly increase water shipments to farmers and cities.
The state will provide about 35 percent of the water requested, the result of a federal court ruling last year. The judge in that case said more water must remain in the Sacramento-San Joaquin Delta to save fish.
Pumping through the delta, the heart of California's water-delivery system, has been cut by more than half to prevent the tiny delta smelt from being sucked into the pumps and killed.
The pumping can increase once the smelt migrate to other parts of the delta. But that will not happen soon enough to make up for the reduced water deliveries, said Don Strickland, a spokesman for the Department of Water Resources.
The snowpack measurements taken Wednesday showed a decline from just a month ago.
In late February, the snowpack was 122 percent of normal in the northern Sierra and 130 percent of normal in the south. The average was 118 percent of normal across the entire 400-mile-long range.
It's not likely to increase through the rest of spring, said Rudy Cruz, a National Weather Service specialist in Reno, Nev.
He said no significant storms are on the horizon. While the region may see light rain or snow in the next few weeks, most of the heavy weather is passing to the north.
"This time of year, things are pretty much done in the Sierra," Cruz said.
