ICE Buildup on Rivers

When Arctic air stays in our area for an extended period of time during the winter months there may be ice buildup on the rivers. If the ice moves there can be a rapid rise in the water level and there is potential for subsequent flooding behind jams. 

The National Weather Service monitors the rivers and streams and will issue ice statements and flood potential outlooks on a periodic basis.
