Lock & Dam 24 at Clarksville is a working Mississippi River structure

At Clarksville, the Mississippi River runs past Lock and Dam 24, one of a series of locks and dams the U.S. Army Corps of Engineers operates to maintain a navigable channel for barge traffic. The structure helps hold a navigation pool upstream and is part of why the river here draws both commercial tows and the wintering bald eagles that fish below the dam. For residents and visitors, the lock and dam is the working backdrop to Clarksville’s riverfront. The Corps’ St. Louis District is the authoritative source for how the structure operates and for any public access, viewing, or safety information. Confirm current public-access and viewing details with the Corps before planning a visit, since operations and access can change.
