Description 

The Lower Mississippi River, below the confluence of the Ohio River at Cairo, Illinois, has always been a reliable zone for river traffic navigation. Not so for the Upper Mississippi River, which was always subject to drought or flood conditions. A proposal to build a series of dams and locks, to guarantee a 9-foot depth was passed under during the Hoover Administration, and built between 1930 and 1940. The series of dams and locks guarantees a navigable channel for recreational and commercial boating along the Mississippi River.
