Snowpack Levels in Nevada: A Mixed Outlook for Water Resources
In early March, the Natural Resources Conservation Service (NRCS) of Nevada undertook a vital snow survey to evaluate the state of the snowpack in the region. This comprehensive survey, conducted at the SNOTEL site on Mt. Rose, provides critical insights into water supply forecasts and other environmental factors.
Jeff Anderson, a hydrologist from the NRCS, utilized a snow tube to delve deep into the snow, verifying the data transmitted by snow telemetry equipment. This hands-on approach ensures the reliability of the data, which includes measurements of annual precipitation, air temperature, snow depth, and soil moisture.
Anderson elaborated on the technique used at the SNOTEL site, explaining, “A snow pillow is a fluid-filled bladder that sits on the ground. It’s right on the surface of the soil, and it acts as a scale to weigh the snowpack.” This method, alongside the snow tube measurements, ensures data accuracy.

The survey’s findings indicated that the snowpack in the Sierra Nevada region is below average, leading to concerns about a prolonged snow-free season and reduced water availability for agricultural needs during the summer months. Anderson noted the unfortunate timing of recent snowstorms followed by rain, which diminished the snowpack significantly, stating, “That was disappointing to have such a tremendous boost to our snowpack and then have some of it erode away.”
While the situation in Nevada is concerning, data from other areas in the Mountain West present a more favorable picture. Anderson highlighted that regions like Wyoming, Montana, and parts of Idaho have experienced better snow accumulation this winter.
Despite these challenges, Nick White, senior groundwater hydrologist for the Truckee Meadows Water Authority, expressed confidence in their current water management plans, saying, “Believe it or not, we’re actually in great shape as we approach the warmer spring and summer months.”
The NRCS plans to conduct the next snow survey in April, which will provide further insights into the evolving snow conditions.
