Several river gauges across Southwest and North Central Montana remain elevated or are indicating minor flooding from ice jams that have resulted from the recent period of very cold temperatures. Areas that are reporting minor flooding include, but are not limited to the following: the Madison River near Ennis and the Missouri River near Cascade. If you see an ice jam occurring, please notify the National Weather Service in Great Falls or your local law enforcement agency for relay to the NWS office in Great Falls. Remember to never walk out onto unstable river ice! Also, remain vigilant near waterways, as flooding can occur rapidly and with little warning if an ice jam upstream breaks up!
