An independent technical study evaluating the use of snowpack depth measurements to estimate snow water equivalent (SWE) of shallow and ephemeral snowpacks in the Great Salt Lake Desert Basin, located in Utah, Nevada, and Idaho. A parameterized bulk snow density model was combined with mean air temperature measurements to predict snow water equivalent in the Great Salt Lake Desert Basin using only snowpack depth measurements and prior 10-day average daily mean air temperatures. The model was developed using historic snowpack data obtained from a limited number of automated snowpack telemetry (SNOTEL) and weather stations within and near the Basin. Model results from lower-elevation, shallow and ephemeral snowpacks may be used to supplement data obtained from existing SNOTEL stations, sparsely located in the higher elevations of the Basin, to create a more-complete and accurate prediction of the Basina€™s snow water equivalent, which may be used to better-manage the water demands of the Basina€™s surrounding populations.Selected project SNOTEL stations, based on proximity to the Great Salt Lake Desert Basin and available snow depth and SWE data (U.S. Department of Agriculture, Natural Resources Conservation Service, 2013; USGS Water Resourcesanbsp;...
