Arkabutla Dam Emergency - Lake Levels Expected to Surpass 220 Feet as Spring Flood Season Begins
Published: February 14, 2025
Arkabutla, Miss. – Recent storms have brought significant rainfall to the Arkabutla Lake area, pushing lake levels above 210 feet and prompting expectations that they will exceed 220 feet within the next two weeks and is dependent on where and when the rain falls. Pool levels at Arkabutla Dam, located in DeSoto and Tate Counties in Northwest Mississippi, can fluctuate quickly especially during the rainy season.
The U.S. Army Corps of Engineers Vicksburg District (USACE-Vicksburg District) declared a potential breach emergency status at Arkabutla Lake in May of 2023, when a depression was discovered near the toe of the dam. The Corps has been maintaining the lake at approximately 204 feet to reduce pressure on the dam and to complete repairs. The Corps will continue to draw down the increased pool levels with releases up to 4,500 cfs until the level reaches the 204 feet target level.
Coldwater River levels below the dam in and around Marks, MS in Quitman County are expected to reach flood stages early next week. The area saw similar conditions on January 10, 2025, when levels crested at 39.6 ft. in Marks. The Corps is coordinating with the National Weather Service and the Mississippi Emergency Management Agency to maximize public awareness in affected areas.
Safety remains a top priority, and the USACE-Vicksburg District has increased to 24-hour surveillance at the dam over the next month. Additional remote monitoring devices are in place and added personnel are on the ground to assess the situation for any changes in the dam.
The physical condition of the dam remains unchanged, and a dam breach is NOT imminent.
With spring flood season underway and the National Weather Service Climate Prediction Center’s seasonal outlook predicting higher-than-average rainfall, the lake and downstream communities are likely to experience more frequent and broader changes in pool and river levels during this time.

Highway 51 Landing provides boating access into the Coldwater River above Arkabutla Dam and will remain the only open boat ramp at Arkabutla Lake. Camping and other recreational use of Arkabutla Lake area remain open, except for day use and fee use areas directly downstream of the dam.
UPDATE: Lake levels expected to rise above 215 feet due to recent rains
Published: December 28, 2024
Vicksburg, Miss – Recent storms dropped between three and five inches of rain in the area upstream of Arkabutla Lake. The lake level has risen above 210 ft. and is expected to peak above 215 ft. in the next few days. Pool levels at Arkabutla Dam, located in DeSoto and Tate Counties in Northwest Mississippi, can fluctuate quickly especially during the rainy season.
The U.S. Army Corps of Engineers Vicksburg District (USACE-MVK) declared a potential breach emergency status at Arkabutla Lake in May of 2023 when a depression was discovered near the toe of the dam. The Corps has been maintaining the lake at approximately 204 ft. to reduce pressure on the dam and to complete interim repairs. The Corps will continue to draw down the increased pool levels with releases up to 4,500 cfs until the level reaches the 204 ft. target level.

Interim Repairs near completion at Arkabutla Dam; Study underway for long-term solutions
Published: September 4, 2024
Vicksburg, Miss – The U.S. Army Corps of Engineers Vicksburg District (USACE-MVK) continues to advance interim risk reduction measures (IRRM) at Arkabutla Dam in Northwest Mississippi that are scheduled to be completed by late September 2024. These measures include adding piezometers to increase real-time monitoring of groundwater pressure and installing relief wells to relieve water pressure and to allow excess water to be diverted safely.
A Dam Safety Modification Study (DSMS) is also underway. The risk reduction measures and the DSMS are in response to an emergency declaration issued in March 2023, when a depression was discovered near the toe of the dam. This study explores options for long-term risk reduction solutions such as structural repairs, modifications, or operational changes, to address the issues at the Dam. The study is expected to be complete in 2025. Once the study is complete and the permanent risk reduction solution is identified, final design and construction will begin.
The long-term solution will likely be substantial, leading to lengthy design and construction periods, possibly up to 9-12 years. It is expected that the pool level at the Dam will be maintained at 204’ throughout the IRRM, the DSMS, and until the long-term solution is complete.
Safety remains a top priority to the USACE Vicksburg District. Lake Staff and additional personnel are vigilantly monitoring the situation at Arkabutla Dam for any changes.
Highway 51 Landing provides boating access into the Coldwater River above Arkabutla Dam and will remain the only open boat ramp at Arkabutla Lake. Camping and other recreational use of Arkabutla Lake area remain open, except for day use and fee use areas directly downstream of the dam.
Recreational activities at Arkabutla Lake will continue during this time such as the annual archery hunt, Outdoor Recreation Day, and MS Wildlife’s Truck or Treat in October, the physically challenged hunt in December, youth waterfowl hunt, youth squirrel hunt, and Bald Eagle survey in January, youth racoon hunt in February, and more.
The USACE Vicksburg District is engineering solutions to the nation’s toughest challenges. The Vicksburg District encompasses a 68,000-square-mile area across portions of Mississippi, Arkansas, and Louisiana, that holds nine major river basins and incorporates approximately 460 miles of mainline Mississippi River levees. The Vicksburg District is engaged in hundreds of projects and employs approximately 1,100 personnel.
Interim Repairs continue at Arkabutla Dam
Published: June 24, 2024 
Vicksburg, Miss – The U.S. Army Corps of Engineers Vicksburg District (USACE-MVK) continues to advance interim risk reduction measures (IRRM) at Arkabutla Dam in Northwest Mississippi. Contractor Frontier Services, Inc., began construction and equipment mobilization in early May.
Currently, drill pads are being installed for piezometers, automated instruments used for monitoring groundwater pressure. Relief wells, which act like valves to relieve the water pressure, allow excess water to be diverted safely, and serve to prevent sand boils, are scheduled to follow. The additional piezometers increase the USACE-MVK’s monitoring ability by sending data hourly to the technical team, allowing them to analyze conditions in real time.
