Flooding due to ice jams is possible into this weekend. Ice jam flooding continues at multiple points along the Musselshell River in Musselshell County as of Monday afternoon, 3/19/18. Ice jams can break up at any time, sending waves of water downstream. Those with interests along ice clogged rivers should be prepared for rapidly rising water. Now is the time to move equipment and livestock out of low lying areas and away from waterways. Follow guidance from local law enforcement and emergency managers. If encountering flooded roadways, Turn Around Don’t Drown! Latest flood information can be found at
