About Colorado snowpack
Snow water equivalent (SWE) is the depth of water held in the snowpack, and it is the single number that best predicts the coming spring and summer runoff. Depth alone can mislead: a deep, dry snowpack can hold less water than a shallow, dense one.
The Waterline reads Colorado's snowpack from the USDA Natural Resources Conservation Service SNOTEL network using the standard basin-index method. It sums the current water content across every reporting SNOTEL station in Colorado (99 on the latest reading), divides by the sum of those same stations' 1991-2020 medians for the date, and reports the ratio as percent of median, so a deep high-elevation site counts for more than a shallow valley one and a station with no long-term normal never distorts the number. The inch figures shown here are the average snow water equivalent across those reporting stations.
Snow builds from about October, normally peaks near April 1, and melts out by early summer. Once the normal snowpack for the date nears zero, percent of median stops being a meaningful number, so this page reports the season's peak instead of a percentage until the snow returns.
