Snowpack in the Roaring Fork Watershed is at historic lows. Levels usually peak in early April and right now, it’s around 60% of normal for this time of year. But, how are these levels determined? Do people go out in the backcountry after a storm and stick rulers in the snow? In early March, Water Education Colorado and the Roaring Fork Conservancy hosted a trip to a Snow Telemetry - or SNO-TEL - site at the top of McClure Pass. KDNK’s Amy Hadden Marsh went along and found out that measuring snowpack is a more than rulers in the snow.
