Port of Catoosa, Oklahoma

The Port of Catoosa is an industrial park northeast of Tulsa, at the end of a constructed waterway known as the McLellan-Kerr Arkansas River Navigation System. The system is a re-engineering of the Arkansas River, and portions of other rivers, with dams, canals, and locks, that was completed by the Army Corps in 1971. It extends for 445 miles from the Mississippi River to the Port of Catoosa, enabling ocean-going barges to travel more deeply into the interior of the country. The industrial park at the Port of Catoosa has around 60 companies, and around 3,500 people working there. It is referred to as the most inland ocean-going port in the nation.
