About Montana Snow Survey
The NRCS Montana Snow Survey Program offers mountain snowpack and precipitation data through manual snowpack measurements (Snow Courses) and the SNOwpack TELemetry (SNOTEL) network to predict snowmelt-driven runoff in the spring and summer. Individuals, organizations, as well as state and federal agencies rely on this information to make decisions related to agricultural production, fish and wildlife management, municipal and industrial water supply, urban development, flood control, recreation, power generation, and water quality management.
