KATV:
Funding from the federal Infrastructure Investment and Jobs Act has put the first significant funding in a decades-long effort to deepen the Arkansas River navigation channel to 12-feet. Much of the river system depth is now at nine feet.
On March 29, the U.S. Corps of Engineers published an addendum of projects funded through IIJA, which included $92.6 million to “initiate construction of the project.” All six members of Arkansas’ Congressional delegation voted against the infrastructure bill.
The Arkansas River system (McClellan-Kerr Arkansas River Navigation system, or MKARNS) is 445 miles long and stretches from the confluence of the Mississippi River to the Port of Catoosa near Tulsa, Okla. The controlled waterway has 18 locks and dams, with 13 in Arkansas and five in Oklahoma. The river also has five ports: Pine Bluff, Little Rock, Fort Smith, Muskogee, Okla., and the Tulsa Port of Catoosa in Oklahoma.
A March 30 presentation by Greg Mattson, deputy chief of operations for the USACE Little Rock District, to the Arkansas Waterways Commission shows that that federal authorization of the channel was made in 2004, and the cost of that work is now estimated at $274.7 million.
