Summary

Completed in 1950, this earth dam stands at a hydraulic height of 23 feet and a structural height of 31 feet, with a length of 425 feet. The dam has a storage capacity of 161 acre-feet, providing a surface area of 13 acres for recreational activities.

Despite its fair condition assessment as of February 2021, Lake Lynn Dam is considered to have a high hazard potential. The dam is regulated by the North Carolina Department of Environmental Quality's Dam Safety Program, which ensures regular inspections and enforcement of safety measures. With a drainage area of 813 square miles and a maximum discharge capacity of 82 cubic feet per second, the dam plays a crucial role in managing water resources in the region.

This dam on Cold Water Creek-Tr not only offers recreational opportunities but also serves as a vital infrastructure for water management in Cabarrus County. Enthusiasts of water resources and climate will find Lake Lynn Dam's design and operational details intriguing, especially considering its location in a region prone to extreme weather events. The ongoing monitoring and maintenance efforts by regulatory agencies underscore the importance of ensuring the safety and sustainability of this essential water resource infrastructure.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
