BACKGROUND: In May of 2016, the Pittsburgh District U.S. Army Corps of Engineers signed a unique Handshake Agreement with 13 local partners in Monroe County, Ohio whose purpose was to restore the grounds and facilities at Hannibal Locks and Dam and reopen the visitor’s center. Using a $25,000 grant awarded to Hannibal Locks and Dam by the Corps, work crews from the lock, along with volunteers from the Ohio Valley River Museum and the community worked tirelessly to renovate, clean, and restore the visitor’s center after being closed to the public for the better part of 16 years following the 9/11 attacks.

MEDIA: On the day of the event, representatives will be available for morning and afternoon broadcast live shots, pre-event coverage, and during the event. Please call the Pittsburgh District PA office to coordinate at 412-395-7500/01/02.

HISTORY: Construction of the Hannibal lock chambers began in 1967 and was completed in 1972 when the locks were opened to river traffic. Work on the high-lift gated dam began in 1970 and was completed in 1975. The installation replaced three older wicket-type projects, Locks and Dams 12, 13 and 14.

PROJECT INFORMATION: The Hannibal project has a gated dam, one of the two major types in service in the Pittsburgh District. Gated dams are constructed to permit increased control over the water level in the navigation pool upriver of the dam. Machinery mounted on tall concrete piers moves large chains, which lift gates that are hinged into the body of the piers. As the gates are raised or lowered to control the amount of water flowing under them, the upstream pool is maintained at a relatively constant level for an authorized depth of at least 9 feet throughout its length. The dam, however, cannot be operated to control flood flows. An incidental benefit derived from the pool formed by the dam is the availability of a source of municipal and industrial water.
