Summary
The dam is an earth dam with a buttress core type and stands at a height of 14 feet, providing a storage capacity of 56 acre-feet. The dam is state-regulated by the Mississippi Department of Environmental Quality, ensuring that it meets necessary safety and environmental standards.
Despite being classified as having a low hazard potential, Mansell Lake Dam is considered to have a moderate risk level. The dam features an uncontrolled spillway and has not been rated for its condition assessment. While the dam has not been modified in recent years, it is subject to regular state inspections and enforcement to maintain safety standards. The surrounding area is not densely populated, reducing the potential impact in the event of a dam failure.
Water resource and climate enthusiasts interested in Mansell Lake Dam can appreciate its role in providing recreation opportunities in the region while being mindful of the moderate risk it poses. With state regulation and inspections in place, the dam serves as a reminder of the importance of maintaining infrastructure to ensure safety and environmental protection. Further monitoring and risk management measures may be needed to address the moderate risk level associated with the dam.

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.
