Hannibal Locks and Dam

This engineering facility features a gravity dam structure combined with lock chambers that enable vessel passage along the Ohio River while managing water levels and flow rates for navigation safety.

Constructed by the U.S. Army Corps of Engineers as part of early 20th century river improvement projects, the facility has undergone upgrades to accommodate modern vessels and enhance operational capacity.

The site represents the industrial heritage of Ohio River transportation, serving as a testament to American engineering achievements in waterway management and commercial river navigation development.

The facility operates continuously under Army Corps supervision, providing real-time water level data through USGS monitoring systems while maintaining navigation channels for commercial and recreational vessel traffic.

The structure incorporates a historic maneuver boat and wicket dam system that demonstrates traditional river management techniques, offering visitors educational insights into inland waterway engineering evolution.
