Summary
Built in 2006 by the NRCS, this earth dam stands at a height of 14.4 feet and has a maximum storage capacity of 230.4 acre-feet. The dam overlooks the scenic UNT of UNT of James Creek and offers a surface area of 25.3 acres for visitors to enjoy water-based activities.
The dam's hydraulic height reaches 11.1 feet, with a structural height of 14.1 feet, ensuring its stability and functionality. While the hazard potential is currently undetermined, the risk assessment categorizes it as moderate (3), prompting the need for ongoing monitoring and risk management measures. Despite its uncontrolled spillway and outlet gates, Duncan Lake Dam remains a popular destination for water resource and climate enthusiasts seeking a tranquil environment for outdoor recreation.
With its picturesque location and moderate risk level, Duncan Lake Dam presents an intriguing site for those interested in water resource management and climate resilience. As a privately owned structure regulated by the Mississippi Department of Environmental Quality, the dam's construction and operation continue to be subject to state permitting, inspection, and enforcement. Whether exploring its design by NRCS or its role in the local ecosystem, Duncan Lake Dam offers a unique opportunity to appreciate the intersection of human infrastructure and natural water systems.

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.
