Summary
Constructed in 1960 by the USDA NRCS, this earth dam serves multiple purposes including fish and wildlife pond creation, fire protection, stock maintenance, and recreational activities. The dam has a structural height of 21 feet and a hydraulic height of 17.2 feet, with a storage capacity of 67 acre-feet and a surface area of 5.8 acres.
Managed by the Tennessee Safe Dams Program, South Point is regulated by the state and undergoes regular inspections to ensure its safety and compliance with regulations. The dam poses a significant hazard potential but has been assessed as satisfactory in condition, with a moderate risk level of 3. Although it lacks outlet gates, the dam has an uncontrolled spillway and a drainage area of 0.26 square miles. With its proximity to the West Harpeth River, South Point plays a crucial role in maintaining water resources and supporting local wildlife habitats.
Overall, South Point stands as a vital structure in the landscape of Williamson County, serving both practical and environmental purposes. With its design geared towards fish and wildlife conservation, the dam contributes to the preservation of natural ecosystems while also offering recreational opportunities for the local community. As climate change continues to impact water resources, South Point's role in managing and protecting these vital resources becomes increasingly significant for the surrounding area.

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.
