Arkansas River commercial tonnage up almost 20% in June
Tonnage shipped on the Arkansas River in June totaled 716,127 tons, up 19.4% compared with 599,946 tons in June 2025. The June traffic followed an unusual 50% tonnage gain in May and a 32.5% jump in April.
The U.S. Army Corps of Engineers reported 5.589 million tons shipped on the river between January and June, up 11.6% compared with 5.007 million in the same period of 2025. The January-June gain follows a 2025 in which tonnage was down 19.5% compared with 2024.
The January through June gain is driven entirely by increased shipments between ports on the Arkansas River system. Much of that increase is driven by an almost 59% year-to-date increase of sand, gravel and rock shipments.
Inbound shipments in the first six months totaled 1.808 million tons, down 12.8% compared with the same period in 2025. The period had 1.724 million tons in outbound shipments, down 5.8% compared with the same period in 2025. Internal shipments — those sent between port operations on the river — totaled 2.055 million tons in the first four months, up 86.6% compared with the same period in 2025.

The Arkansas River system — McClellan-Kerr Arkansas River Navigation System (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 commercial ports: Pine Bluff, Little Rock, Fort Smith in Arkansas and Muskogee and the Tulsa Port of Catoosa in Oklahoma.
According to the Arkansas Waterways Commission, the average annual freight tonnage on the MKARNS is approximately 12 million tons. On land, 381,857 semi-trucks or 99,283 railcars would be required to ship the same amount.
