Summary
Completed in 1947, this earth dam stands at a height of 14 feet and has a length of 465 feet, providing a storage capacity of 88 acre-feet for recreational purposes. Despite its significance for recreation, the dam is currently assessed as being in poor condition, with a significant hazard potential, as per the last inspection in February 2019.
Managed by the South Carolina Department of Health and Environmental Control (DHEC), Mirror Lakes Dam 2 is subject to state regulations, permitting, inspections, and enforcement. The dam's emergency action plan (EAP) was last revised in 1994, raising concerns about its readiness in case of an emergency. With its location in a high-risk area, it is crucial for stakeholders to prioritize risk management measures and ensure the safety and integrity of the dam to prevent any potential disasters or emergencies.
As water resource and climate enthusiasts, it is essential to recognize the importance of maintaining and monitoring dam infrastructure like Mirror Lakes Dam 2 to safeguard the surrounding communities and the environment. By addressing the poor condition assessment and significant hazard potential, stakeholders can work towards implementing necessary risk management measures and ensuring the dam's structural integrity for continued recreational use and protection against potential emergencies.

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.
