The nearest town to Newt Graham Lock and Dam 18 is Inola, Oklahoma, established as a post office in 1890. The name is a Cherokee word meaning “black fox.”
The Port of Catoosa, at the head of the navigation channel, is named for the town of Catoosa, formerly a roisterous cattle shipping point. It took its name from “Old Catoos,” the rounded hill just west of the town. The word is from the Cherokee expression, “Gi-tu-zi,” meaning “Here live the People of the Light.” It is said that the “People of the Light” clan formerly met on the summit on the hill.
