Summary

Built in 1955, this earth dam stands at a structural height of 17 feet with a hydraulic height of 12.1 feet. The primary purpose of Mundorf Lake Dam is for recreation, offering a surface area of 10.9 acres and a normal storage capacity of 45 acre-feet.

With a drainage area of 482 square miles, Mundorf Lake Dam plays a crucial role in managing water resources in the region. The dam has a high hazard potential and was last assessed to be in fair condition in December 2020. The North Carolina Dam Safety Program oversees the regulation, permitting, inspection, and enforcement of the dam to ensure its safety and compliance with state standards.

Enthusiasts of water resources and climate will find Mundorf Lake Dam to be a fascinating structure that provides both recreational opportunities and essential water management functions. Its picturesque location and significant storage capacity make it a valuable asset in the region, highlighting the intersection of human engineering with natural resources and the importance of proper dam maintenance and regulation in safeguarding communities from potential hazards.

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.
