Newt Graham Lock and Dam

Newt Graham Lock & Dam is the final lock and dam of the McClellan-Kerr Arkansas River Navigation System (MKARNS) before reaching the western terminus, Tulsa Port of Catoosa on the Verdigris River. The lock and dam is 24.8 miles (39.9 km) downstream of the port.

Experience the hidden wonders of the McClellan-Kerr Arkansas River Navigation System.  Newt Graham Lock and Dam 18 project was primarily constructed for the improvement of the Arkansas River and its tributaries for commercial barge traffic; however, it also offers recreation and resource opportunities.

The lock and dam are named for a major Tulsa supporter of the Arkansas River Navigation Project. In order to facilitate water transportation to the Port of Catoosa, it was necessary to have a way to raise barges from the level of the Mississippi 420 feet below to the elevation of the Verdigris River.

Newt Graham is the farthest upstream structure on the navigation project and is located approximately 7 miles south of Inola, Oklahoma.  The Lock 18 pool offers 24.8 miles of navigable waters between the lock and the Port of Catoosa. In an average year, 13-million tons of cargo is transported on the McClellan-Kerr by barge.  This ranges from sand and rock to fertilizer, wheat, raw steel, refined petroleum products, and sophisticated petrochemical processing equipment.
