The California Cooperative Snow Survey shows improvement in Sierra Nevada snowpack at 114% of normal but California remains under the effects of a four-year drought.

State water officials conducted a manual survey on Tuesday and found snow depths ten times higher than a year ago at survey sites.

But the state's largest reservoirs remain low with storage ranging from about one-third to three-quarters of average.
