Navigation, commerce, recreation, and hydropower, the Dardanelle Lock and Dam outside of Russellville, Arkansas has it all. Seen here from the overlook at Old Post Park, a barge navigates the lock as it works its way downriver.
Workers completing the initial repairs to the McLean Bottom Levee near Paris, Arkansas. Damaged during the 2019 high-water event, the Little Rock District worked closely with the Arkansas Levee Task Force as well as state and local leaders to begin repairing the damage. With this work done, the levee now has a 25-year level of protection.
Headed down the Arkansas, a barge locks through at the Ozark-Jetta Taylor Lock and Dam. Located at mile 308 of the river, the Ozark lock and dam is just one unit of the McClellan-Kerr Arkansas River Navigation System (MKARNS) that originates at the Port of Catoosa in Tulsa, Oklahoma. Running southeast through Oklahoma and Arkansas to the Mississippi River, the MKARNS ensures a 9-foot navigable channel for commercial barge traffic. The MKARNS is a "high-use" waterway system that routinely sees more than 10 million tons of traffic a year.
Thousands visit the Big Dam Bridge in Little Rock, every single day. The Little Rock District is one of the most visited USACE districts in the nation and recreation is one of the key reasons why.
The Little Rock District monitors and directs the release of water from 25 water resource projects. Our efforts support flood control, hydropower, navigation, fish & wildlife, municipal & industrial water supply, and recreation.
