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.

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.
