U.S. Department of Agriculture (USDA) Snow Survey and Water Supply Forecasting

The Snow Survey and Water Supply Forecasting program provides western states and Alaska with information on future water supplies (January - June for the current year). USDA Natural Resources Conservation Service field staff collect and analyze data on depth and water equivalent of the snowpack at more than 1,200 mountain sites and estimate annual water availability, spring runoff, and summer streamflows. Individuals, organizations, and state and federal agencies use these forecasts for decisions relating to agricultural production, fish and wildlife management, municipal and industrial water supply, urban development, flood control, recreation power generation, and water quality management.
