Flood — Big Horn, WY

Feb 10, 2017

A rapid warm up following several weeks of below normal temperatures and above average snowfall led to flooding along the Big Horn River in Washakie and Big Horn Counties. The result was rapidly rising rivers due to ice jams from rivers breaking up as well as rapid snow melt. The Worland area was the hardest hit area. Over 100 homes were evacuated in low lying areas near the river in Worland as it rose to around 13.9 feet, well above flood stage. The water receded as the ice jam moved northward.
