Work on the second phase of interim risk-reduction measures at Arkabutla Dam is set to begin roughly five months after officials originally planned to start construction.
The U.S. Army Corps of Engineers announced Wednesday that work will begin in early June to further stabilize the flood control structure in DeSoto County while also reducing risks for downstream communities. Crews were originally supposed to begin in January. Officials did not explain the reason for the delay.
The renovations are taking place more than three years after a depression was discovered at the toe of the dam, prompting emergency actions to be taken to protect from possible flooding due to a breach.
Phase II work includes grouting the tunnel through the dam’s foundation to fill voids. To safely access the area, crews have closed the dam’s gates, which will temporarily stop releases of water. If the lake reaches critical levels during the gate closure, work will be paused, and necessary releases will be made. The target pool level of 204 feet will remain in place after interim repairs are complete, officials say.
For those wanting to access Arkabutla Lake for recreational purposes, Highway 51 Landing will continue to provide boating access into the Coldwater River upstream from the dam. Camping and other recreational use of the Arkabutla Lake area will remain open, except for day use and fee use areas directly downstream of the dam.
Constructed in 1943, Arkabutla Dam is 65 feet high, 10,000 feet long, and reduces flood risk for approximately 19,000 residents. The dam protects an estimated $510 million in homes and businesses.
