Summary
Completed in 1955, this earth dam stands at a height of 15 feet and stretches out to a length of 290 feet. It boasts a storage capacity of 110.8 acre-feet, with a normal storage level reaching 60.5 acre-feet.
Despite its importance for recreation, South Lake Dam poses a high hazard potential and is currently assessed as unsatisfactory in condition. This assessment was conducted in August 2019, with the last inspection taking place in November 2020. The dam is under the regulatory oversight of the Mississippi Department of Environmental Quality, ensuring that state permitting, inspection, and enforcement measures are in place to mitigate risks associated with its operation.
With its location on the UNT of Moore's Creek, South Lake Dam plays a crucial role in managing water resources and protecting the surrounding environment. As climate change continues to impact water systems, the maintenance and safety of structures like South Lake Dam become increasingly important for ensuring the resilience of communities against potential flooding and other water-related hazards.

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.
