A number of Corps projects have been constructed on the Arkansas River between the Dardanelle dam and the confluence of the Arkansas and Mississippi Rivers. The entire project, known as the McClellan-Kerr Navigation system, connects ports as far west as Eastern Oklahoma with the Mississippi River and the Gulf of Mexico. Completed in 1968, the McClellan-Kerr Navigation System consists of a series of locks and dams to allow for traffic up and down the Arkansas River.
