History and Features
Opened in October of 2003, this museum is the newest of 9 regional visitor centers operated by the US Army Corps of Engineers. Using hands-on technology, exhibits explore the history and nature of the Mississippi River. From its early beginnings to its use as a highway for commerce, this museum takes visitors on a voyage through time. Try your hand at a barge simulator or explore a computerized naturalist notebook. You can even send an
electronic postcard to your friends or browse the Confluence Store for the latest river related books or gift items. Also available is a theater where you can choose between 2 movies - the "Power of the River" or "Lewis and
Clark: Confluence of Time and Courage". Then take a stroll across the river by joining a tour of the lock and dam. Given daily at 10 AM, 1 or 3 PM (weather permitting), these tours give you a close up view of the activities
of a working modern lock.
