Summary
This earth dam, with a buttress core type, serves the primary purpose of recreation, offering a serene getaway for water resource and climate enthusiasts. Despite its low hazard potential and moderate risk assessment, the dam's condition remains unrated, suggesting the need for further evaluation to ensure its long-term safety and resilience.
Situated in Warren County, Mississippi, the dam boasts a height of 18 feet and a storage capacity of 80 acre-feet, making it an essential component of the local water management system. While currently lacking detailed information on construction year, dam volume, and other key metrics, the presence of an uncontrolled spillway highlights the importance of continued monitoring and maintenance to mitigate any potential risks. With its picturesque location and potential for outdoor activities, R O Duncan Lake Dam symbolizes the delicate balance between human enjoyment and environmental stewardship in the realm of water resource management.
As water levels fluctuate and climate patterns evolve, the significance of R O Duncan Lake Dam as a recreational resource and water management asset becomes increasingly apparent. Its designation as a private structure underscores the shared responsibility of all stakeholders in ensuring the dam's safety and functionality for future generations to appreciate. Whether through enhanced inspections, updated emergency preparedness measures, or increased risk management efforts, the ongoing stewardship of R O Duncan Lake Dam exemplifies the intersection of environmental conservation and public enjoyment in a changing climate landscape.

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.
