Summary
Completed in 1977, this rockfill dam serves the primary purpose of flood risk reduction, with additional functions for recreation and water supply. Standing at a height of 160 feet and a length of 1563 feet, the dam has a storage capacity of 370,600 acre-feet and covers a surface area of 1,700 acres on the Rolling Fork River.
Managed by the US Army Corps of Engineers, Dequeen Dam - Saddle Dike E has a high hazard potential due to its limited water storage capacity and the potential risks associated with severe weather events. To mitigate these risks, the USACE implements a comprehensive risk management strategy, which includes continuous monitoring of the dam's condition, regular maintenance and repairs, as well as collaboration with local emergency managers to develop emergency action plans. Despite its high hazard potential, the dam meets guidelines for emergency preparedness and has an effective risk management approach in place.
As part of ongoing efforts to address flood risks, the USACE regularly updates the emergency action plan for Dequeen Dam - Saddle Dike E and works closely with local stakeholders to raise awareness and ensure readiness for potential dam-related emergencies. With a commitment to managing dam-related flood risks and ensuring the structural integrity of the dam, the USACE remains dedicated to the safety and security of the surrounding community and water resources.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
