Event Overview

The Ohio River Flood of 1964 was caused by a series of winter storms that produced heavy rainfall and rapid snowmelt across the watershed. River levels rose quickly, overwhelming flood control structures and inundating communities along the Ohio River. Southern Ohio cities experienced significant flooding that damaged homes, businesses, and transportation networks. Although less severe than earlier historic floods, the 1964 event underscored the ongoing challenges of managing winter flood risks. The flood prompted additional improvements to regional flood control systems. Its impact remains part of Ohio’s long history of river flooding.
