Weekly Snowpack and River Report
February 20, 2020 -
Snowpack in the Roaring Fork Watershed is currently 116% of normal for this time of year. February’s cold temperatures are keeping snow on the mountain and creating some interesting ice conditions in local rivers and streams. Last Thursday, anchor ice expert Dr. Ed Kempema from the University of Wyoming, shed much light on the differences of ice creation and detachment in both still and flowing water. During this Brooksher Watershed Institute presentation, participants learned about how 1/100 of a degree can produce supercooling and how the sun’s radiation provides just enough heat to detach anchor ice. Here’s something fun to try before winter is over - The next time overnight temperatures dip well below freezing, look for anchor ice attached to the bottom of the Roaring Fork River at first daylight. Not long after the sun ever so slightly heats up the water you will observe the river looking like a slushy - that “slushy” is detached anchor ice from upstream.
