Map Layer Information: SNOTEL Sites

The Natural Resources Conservation Service (NRCS) installs, operates and maintains an extensive, automated system designed to collect snowpack and related climatic data in the Western United States and Alaska. This system, called SNOTEL (for SNOwpack TELemetry), operates over 660 remote sites in mountain snowpack zones. Congress mandated NRCS (then the Soil Conservation Service) in the mid-1930s to measure snowpack in the mountains of the West and forecast the water supply. Manual measurement of snow courses was the norm until 1980.
