SWE is the depth of water you would get by melting the whole snowpack. Alta Lakes's 4″ of snow holds 1.6″ of water, so the pack is about 40% water. Fresh powder is often 5 to 10%; old spring snow can be 40% or more.
The station reports every hour by radio telemetry to the USDA Natural Resources Conservation Service. This page refreshes each hour. Readings are provisional until NRCS quality control.
It compares today’s SWE with the 1991–2020 median for the same calendar day at this station. Above 100% means more water in the snowpack than on a typical year’s same date.
