Abstract: During winter months, ice jams may form on rivers, lakes, and streams in cold regions. Ice jams form during initial ice cover formation as the ice accumulates, restricting water flow (freezeup jam), and also when the ice cover breaks apart and begins to move (breakup jam) (Fig. 1). When rivers become jammed with ice, riverine communities upstream from an ice jam can suffer severe effects as a result of backwater flooding and structural impacts of ice. Excessive water and ice associated with ice jams often causes damage to bridges, roads, and buildings. Roads and runways can be forced to close, and bridges can be damaged or destroyed, delaying or limiting emergency aid in evacuation situations. Transportation of heating fuel and other necessary cargo can be temporarily halted as both roadways and waterways are affected.
