Did You Know? Locks & Dams on the Ohio and Kanawha Rivers Are NOT Flood-Control Dams
The locks and dams operated by the U.S. Army Corps of Engineers Huntington District on the Ohio and Kanawha Rivers are designed primarily for navigation — not flood control.
These structures maintain dependable river depths for commercial and recreational navigation. The locks move vessels between pools of different elevations, helping keep commerce moving along our inland waterways.
During high-water events, navigation dams do not store floodwater like flood-control reservoirs. As river levels rise, their influence on the river diminishes and they are operated to safely pass the increasing flow.
Navigation Locks & Dams = Maintain navigable waterways
Flood-Control Dams & Reservoirs = Store water to reduce downstream flood risk
Knowing the difference helps explain how USACE manages the Ohio and Kanawha Rivers.
