Summary

Situated on Lampley Branch-Os, the dam boasts a structural height of 30 feet and a hydraulic height of 22 feet, offering a serene 3-acre surface area for visitors to enjoy. With a normal storage capacity of 44 acre-feet and a maximum storage of 53 acre-feet, the dam serves as a picturesque destination for water resource and climate enthusiasts alike.

Although privately owned, Moore Lake Dam undergoes state inspections to ensure its safety and compliance with regulations. Despite being classified as having a low hazard potential and a condition assessment of "Not Rated," the dam has not been modified in recent years and is due for further inspection to assess its current state. With a drainage area of 371 square miles and a maximum discharge of 33 cubic feet per second, the dam plays a crucial role in managing water resources in the region, making it a vital asset for both recreational and environmental purposes.

As visitors immerse themselves in the tranquil surroundings provided by Moore Lake Dam, the dam's historical significance and recreational value continue to draw attention from water resource and climate enthusiasts. With its idyllic location in Cheraw Sc and close proximity to the Wilmington District, the dam remains a beloved destination for those seeking a peaceful retreat amidst the beauty of nature. Whether observing the dam's impressive hydraulic height or exploring its 360-foot length, Moore Lake Dam offers a captivating experience for all who appreciate the intersection of water resources and climate in a picturesque setting.

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.
