Event Overview
The 2020 Ohio River Basin Flooding occurred after a series of winter storms brought heavy rainfall to an already saturated watershed. River levels rose steadily, pushing the Ohio River and its tributaries to near flood stage across southern Ohio. Communities experienced moderate to severe flooding that damaged homes, parks, and riverfront infrastructure. The event disrupted transportation networks and forced temporary closures along major roadways. Although not as catastrophic as earlier historic floods, the 2020 event underscored the persistent flood risks associated with winter storm patterns.
