St. Louis District Website

Engineers Far From Ordinary: The U.S. Army Corps of Engineers in St. Louis takes a look at the story of the St. Louis District beginning with the rich and legendary history of the river as well as the modern history of the District’s innovations in response to the challenges of simultaneously maintaining and regulating navigation, protecting again flooding, and protecting the environment.

The St. Louis District is responsible for maintaining a navigation channel nine feet deep and 300 feet wide on 300 miles of the Mississippi River from Saverton, Missouri, to Cairo, Illinois. We are also responsible for maintaining a navigation channel on the lower 80 miles of the Illinois River as well as the lower 36 miles of the Kaskaskia River. Strategically situated at the crossroads of three major river systems, the St. Louis District is also located at the critical transition point on the Mississippi River where it is a “locking river” north of St. Louis and the “open river” from St. Louis on south.
