Event Overview

Ice jam flooding occurs when large sheets of river ice break apart and accumulate at narrow points, blocking water flow and causing rapid upstream flooding. Ohio has experienced numerous ice jam events along the Ohio River, Muskingum River, and Maumee River. These floods can develop suddenly and cause significant damage to homes, roads, and infrastructure. Emergency responders often monitor river conditions closely during winter thaws. Ice jam flooding remains a recurring seasonal hazard in Ohio.
