Summary
Despite its significant hazard potential and poor condition assessment, the dam serves as a crucial resource for the surrounding area. Managed by the local government and regulated by the South Carolina Department of Health and Environmental Control, the dam's primary purpose is to ensure a reliable water supply for the community.
With a height of 41 feet and length of 135 feet, Lake Terry Dam impounds the waters of Little Fork Creek, providing a surface area of 50 acres for recreational activities. The dam's earth construction with a stone core foundation signifies its resilience against hydraulic pressures. However, the dam's poor condition assessment highlights the need for regular inspections and maintenance to ensure its structural integrity and safety for the community.
Despite its challenges, Lake Terry Dam plays a crucial role in water resource management in the region, emphasizing the importance of continued monitoring and upkeep to safeguard its functionality and prevent potential risks to the community and environment. As a key component of the local water supply infrastructure, the dam's maintenance and regulatory oversight remain crucial for ensuring the safety and sustainability of the surrounding area's water resources amidst changing climate conditions.

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.
