Improving forecasting for water supply from California snow melt
USGS is data used to estimate snowmelt and runoff, and to develop products for forecasting water-supply needs under extreme conditions, such as drought.

A drought is a period of drier-than-normal conditions that results in water-related problems. When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought.
