Winter Flooding:The Risks

Every region in the United States is at risk for winter flooding. Many people focus primarily on ice and snow this time of year, but it is important to also consider winter flood risks.

Ice Jams

Long cold spells can cause the surface of rivers to freeze, leading to ice jams. When a rise in the water level or a thaw breaks the ice into large chunks, these chunks can become jammed at man-made and natural obstructions, resulting in severe flooding.


A sudden thaw can produce large amounts of runoff in a short period of time. Because the ground is hard and frozen, water cannot be reabsorbed. The water then runs off the surface and flows into lakes, streams, and rivers, causing excess water to spill over their banks.

Floods are the #1 natural disaster in the U.S. 

Flooding causes damage and destruction across regions nationwide, wiping out homes and businesses. However, many residents and business owners are unaware that they qualify for flood insurance. You can take steps to reduce the financial impact of flooding before a disaster strikes. One important step is to understand your risk. The cold winter season can lead to flooding situations from ice jams plus mountain and valley snow melt.
