Weekly Snowpack Report
December 4, 2025 -
Summary:
We begin December with the first snowpack report of the season. On the map below, notice the addition of snowflake icons, each representing a SNOTEL site - a remote data collection site administered by the Natural Resources Conservation Service that monitors snowpack throughout the winter. Snowpack is recorded as snow water equivalent (SWE) which is the amount of water contained within the snowpack, rather than the depth of snow. Monitoring SWE is critical in Colorado as 80% of the state’s water supply comes from snow. Currently, snowpack in the Roaring Fork Watershed is much below average at 49% of normal for this time of year. Join us on December 12 at Bristlecone Mountain Sports as Joel Gratz, founding meteorologist and CEO of OpenSnow, talks AI Innovations for Weather, Snow, and Avalanche Risk.

Calling All River Users to Protect Waterways from New Threats
It is time for every water user to take seriously their role in being a river steward. After you fish, boat, kayak, or stand-up paddleboard CLEAN, DRAIN, and DRY all your gear. Every time. Yes, really, every time.
