As millions of Americans plan visits to our nation’s lakes and rivers, the St. Louis District U.S. Army Corps of Engineers reminds visitors of the importance of practicing safe, sensible, and thoughtful activities in, on, and around open water. Tragically, people lose their lives while visiting USACE-managed lands and waters every year. Most of the tragedies are water related. The public’s help is needed to reduce the number of fatalities at the more than 2,800 USACE-managed recreation areas nationwide. USACE personnel stress the importance of water safety year-round when talking with visitors, but especially during the summer season because that is when most public recreation fatalities occur

Lock and Dam 25 is equipped the 1,296-foot long dam structure with three submersible roller gates (near the center of the structure, see image at right) and 14 submersible tainter gates. At the time of construction, the submersible gates represented a marked advance in gate design and were seen as an improvement over non-submersible gates because they allowed for the almost unobstructed flow of floodwaters, ice and debris.

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.
