This remarkable site on the Upper Mississippi River, bridging Illinois and Missouri near Clarksville, stands as both a vital piece of navigational infrastructure and a phenomenal wildlife observation point. Built as part of the ambitious Nine-Foot Navigation Project, the lock and dam is especially famous for its innovative use of Tainter gates, a groundbreaking engineering feat at the time of its construction. Visitors can experience the powerful operations of river commerce alongside the serene beauty of the Mississippi's ecosystem.

What truly sets Lock and Dam No. 24 apart is its role as a magnet for a diverse array of birdlife, particularly during the colder months.
