Peoria Lock and Dam
Peoria Lock and Dam, Navigation lock and dam system on Illinois River at Creve Coeur, United States
The Peoria Lock and Dam features a 600-foot chamber with water leveling mechanisms that enable vessel passage through different river elevations.
The U.S. Army Corps of Engineers constructed this infrastructure between 1938 and 1939 to improve navigation between Chicago and the Mississippi River.
The control station incorporates Art Deco design elements at its entrance, reflecting architectural preferences of federal projects during the 1930s.
The lock chamber measures 100 by 600 feet with an 11-foot vertical lift capability, accommodating commercial vessels traveling along the Illinois River.
The dam contains 108 Chanoine wicket gates and remains one of only two structures in Illinois maintaining this historical engineering system.
