Lock and Dam No. 22 stands as a pivotal structure on the Upper Mississippi River, bordering Pike County, Illinois, and Saverton, Missouri. This impressive engineering marvel is integral to maintaining the nine-foot navigation channel, facilitating commercial and recreational river traffic alike. It serves as a fascinating intersection of human ingenuity and natural ecosystem, offering visitors a dynamic view of river operations and vibrant wildlife drawn to its waters.
The area surrounding Lock and Dam No. 22 is a haven for nature enthusiasts, particularly birdwatchers. The turbulent waters below the dam provide open foraging grounds, attracting significant numbers of bald eagles, especially during the winter months when other parts of the river freeze over. Visitors can witness the impressive sight of these majestic raptors hunting, alongside various migratory waterfowl and wading birds like pelicans, ospreys, gulls, and terns during spring and fall. Furthermore, a pioneering fish passage structure is currently under construction, poised to restore upstream migration for native warmwater fish species like paddlefish, shovelnose sturgeon, and channel catfish, promising enhanced biodiversity.
A visit to Lock and Dam No. 22 offers an enriching experience, blending historical significance with active ecological efforts. Whether you're captivated by the intricate dance of towboats locking through, the powerful flight of an eagle, or the serene act of fishing from the earthen dike, this site provides a memorable connection to the enduring spirit of the Mississippi River. The ongoing fish passage project highlights a commitment to environmental stewardship, making it an exciting place to witness conservation in action.

Lock and Dam No. 22 was constructed between 1934 and 1939 as a vital component of the U.S. Army Corps of Engineers' Upper Mississippi River Nine-Foot Channel Project. Authorized under the Rivers and Harbors Act of 1930, the project aimed to improve navigation depth and provide economic relief during the Great Depression. The lock's construction commenced in December 1933, followed by the dam in September 1936. The facility officially opened on July 22, 1938, with federal appropriations totaling nearly $4 million. In 2004, the site was recognized for its historical significance and was listed in the National Register of Historic Places as Lock and Dam No. 22 Historic District. More recently, in early 2023, groundbreaking occurred for a first-of-its-kind fish passage structure, a major ecosystem restoration effort designed to reconnect fragmented river habitats for native migratory fish. This project is expected to be completed in FY27.
