Summary
The earth dam stands at a height of 11 feet and spans 455 feet in length, with a storage capacity of 105 acre-feet. The dam overlooks the TR-LAKE SWAMP, providing a serene backdrop for outdoor activities.
Owned privately, Leo Hanna Pond Dam is regulated by the South Carolina Department of Health and Environmental Control, with state permitting, inspection, and enforcement in place to ensure safety standards are met. Despite its low hazard potential, the dam's condition is currently not rated, with the last inspection conducted in February 2013. With a surface area of 15 acres and a normal storage capacity of 60 acre-feet, Leo Hanna Pond Dam continues to attract visitors seeking a peaceful retreat surrounded by nature.
Although Leo Hanna Pond Dam does not have a designated spillway, its primary purpose remains focused on recreation. With Tom Rice (R) serving as the Congressional Representative for the area, the dam provides a haven for water resource and climate enthusiasts alike. As efforts to maintain and monitor the dam continue, it stands as a symbol of responsible water management in the region, blending leisure with environmental stewardship for all to enjoy.

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.
