The Port of Catoosa is located near the homonymous city of Catoosa, Rogers County, Oklahoma. It is called the Tulsa Port of Catoosa because it is located within the municipality of Tulsa. It opened at the end of 1970 and, apart from being the largest port in Oklahoma, it is one of the largest inland river-ports in the United States. The port is the starting point of the McClellan-Kerr Arkansas River Navigation System (named after the two senators that were able to secure the funding to build it), which runs through the states of Oklahoma and Arkansas to the Mississippi River, covering a distance of 445 miles. The system was built by and is managed by the U.S. Army Corps of Engineers. The port serves manufacturing companies, mostly from the oil and gas industry, as well as the agricultural sector.
