Chouteau Lock & Dam
The 928th tallest dam in the world
Chouteau Lock & Dam, also identified as Chouteau Lock & Dam 17, is 17th lock and dam of the McClellan-Kerr Arkansas River Navigation System (MKARNS) from the Mississippi River to its terminus at the Tulsa Port of Catoosa, and is the first lock and dam on the Verdigris River in Oklahoma, just above the Three Forks junction with the Arkansas River. The lock is about 4 miles (6.4 km) northwest of Okay in Wagoner County, Oklahoma. Construction of this facility started in 1966 and was completed in 1970. The estimated cost of Chouteau Lock & Dam was $ 31.8 million. The lock and dam was named for the family of Auguste Pierre Chouteau (1786-1838), who was a pioneer European that settled in this area during the late 18th and early 19th Century.
