The episode as NWS TFX wrote it up.
Warmer temperatures, after an extended cold and snowy period, caused numerous flooding problems across central Montana during the second week of February. Snowmelt over frozen ground caused streams and rivers to go out of their banks, washing out roads and bridges. Flooding problems ranged from minor inundation of fields to portions of towns being under water. Ice jams also caused flooding problems as snowmelt ran into frozen streams and rivers. Some of the worst flooding occurred in East Helena where 3 creeks went out of their banks, damaging over 150 homes. Ice jams on the Missouri river caused flooding in Fort Benton. Much of the town was under 1 to 2 feet of water at one point. Other significant flood damage occurred in White Sulpher Springs, Bozeman, Belgrade, Chinook, Anaconda, and Butte.
