Lock & Dam 20 at Canton is a federal river structure
Lock and Dam 20 on the Mississippi at Canton is part of the federal navigation system run by the U.S. Army Corps of Engineers, shaping the river, barge traffic, and the local waterfront.
At Canton, the Mississippi River is managed by a U.S. Army Corps of Engineers lock and dam, generally identified as Lock and Dam 20. It is one of a chain of locks and dams that maintain a navigable channel for barge traffic on the Upper Mississippi. Lock and Dam 20 is operated by the Corps of Engineers’ Rock Island District, and it sits along the river just north of Canton. For residents and visitors, the structure shapes river levels near Canton, supports commercial navigation, and can be a place to watch tows lock through. River pools behind these dams also affect fishing and recreation. The Corps of Engineers, which runs the river’s navigation system, is the authoritative source for how the lock works, current operations, and any public access. Confirm current visitor access and any viewing areas with the Corps before planning a visit, since operations and public-access arrangements at federal river structures can change.
