Summary

Built in 1900, this earth dam stands at a hydraulic height of 20 feet and a structural height of 23.5 feet, with a length of 325 feet. Its primary purpose is for recreation, providing a storage capacity of 7 acre-feet and a surface area of 0.7 acres. The dam is state-regulated by the NC Dam Safety Program, ensuring regular inspections and enforcement to maintain its fair condition and high hazard potential.

Situated on the UT to Little Branch river or stream, Seymour Farms Pond Dam has a normal storage capacity of 6 acre-feet and a drainage area of 9 square miles. The dam has a maximum discharge rate of 300 cubic feet per second, emphasizing the importance of its effective management and maintenance. While the dam's hazard potential is considered high, its fair condition assessment and regulated state inspection ensure that necessary measures are in place to mitigate risks and protect the surrounding community from potential emergencies.

For water resource and climate enthusiasts, Seymour Farms Pond Dam offers a fascinating insight into the intersection of human recreation and environmental stewardship. Its historical significance, engineering design, and regulatory oversight provide a unique case study in balancing the benefits and risks associated with earth dams in North Carolina. As a key feature of the local landscape, this dam serves as a reminder of the importance of sustainable water management practices and the need for ongoing monitoring and maintenance to ensure the safety and integrity of our water resources.

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.
