About the Snow Survey Program in Arizona

NRCS hydrologists manage a comprehensive network of manually-measured snow courses and automated Snow Telemetry (SNOTEL) monitoring sites throughout the West, manage the data collection process, and estimate the runoff that will occur when it melts.

States in the West collect mountain snowpack and precipitation data in their areas, and offer regular reports on those areas utilizing the national database.

Individuals, organizations, and state and federal agencies use the information provided 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.

NRCS in Arizona uses a network of 43 snow measurement sites to monitor the snowpack and precipitation across 8 reservoir systems in the state.
