Summary
With a hydraulic height of 29.7 feet and a structural height of 33.3 feet, the dam stands on the North Fork Mountain Creek - Tr, offering a serene and picturesque setting for water resource and climate enthusiasts to explore. The dam has a storage capacity of 191 acre-feet, with a normal storage level of 128 acre-feet and a surface area of 13.8 acres.
Despite its high hazard potential, Mirror Lake Dam is currently assessed to be in fair condition as of the last inspection in December 2019. The dam is regulated, permitted, inspected, and enforced by the North Carolina Department of Environmental Quality's Dam Safety Program, ensuring its safety and compliance with state regulations. While the dam does not have a spillway or outlet gates, its associated structures are minimal, reflecting its primary purpose of providing a recreational oasis for visitors to enjoy. Overall, Mirror Lake Dam serves as a vital infrastructure piece that harmoniously integrates with its natural surroundings, offering a tranquil escape for those interested in water resources and climate conservation.

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.
