Summary
The dam stands at a hydraulic height of 51.5 feet and a structural height of 55 feet, with a length of 1940 feet. It has a normal storage capacity of 40 acre-feet and a maximum storage capacity of 58 acre-feet, covering a surface area of 3.7 acres in Person County. The dam's hazard potential is considered high, but its condition assessment as of September 2020 was deemed satisfactory.
Managed by a public utility, Mayo Fgd Settling Basin Dam is regulated by the North Carolina Department of Environmental Quality's Dam Safety Program. The dam is subject to state permitting, inspection, and enforcement, ensuring its ongoing compliance with safety standards. Despite its high hazard potential, the dam's condition is regularly assessed, with emergency action plans in place and updated as needed. With a history of satisfactory performance and a focus on flood risk reduction, Mayo Fgd Settling Basin Dam plays a crucial role in protecting the surrounding area from potential inundation.
Located at a latitude of 36.539 and a longitude of -78.883, Mayo Fgd Settling Basin Dam is a key infrastructure project in North Carolina's efforts to mitigate flood risks. With a design focused on concrete construction and a significant height to safeguard against high water levels, the dam serves as a vital barrier against potential disasters. By adhering to state regulations, undergoing regular inspections, and maintaining a satisfactory condition, Mayo Fgd Settling Basin Dam demonstrates a commitment to ensuring the safety and security of the local community and environment in the face of changing climate conditions.

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.
