Summary
Completed in 1952, this earth dam stands at a hydraulic height of 15 feet and a structural height of 19 feet, with a length of 140 feet. The dam has a storage capacity of 38 acre-feet and covers a surface area of 5 acres, drawing from a drainage area of 1075 acres.
Maintained and regulated by the North Carolina Dam Safety Program, the Yanceyville Water Supply Dam is subject to regular inspections to ensure its safety and functionality. With a hazard potential rated as high and a condition assessment deemed fair as of the last inspection in February 2020, the dam plays a crucial role in managing water resources in the region. Despite its age, the dam continues to fulfill its primary purpose of providing water supply to the surrounding area, showcasing the importance of infrastructure in adapting to changing climate conditions and water resource management challenges.
As a key component of the Country Line Creek-Tr watershed, the Yanceyville Water Supply Dam exemplifies the intersection of water resource management, infrastructure maintenance, and climate resilience. With a history dating back to the mid-20th century, this dam stands as a testament to the ongoing efforts to balance the needs of water supply with the imperative of ensuring dam safety and regulatory compliance. For water resource and climate enthusiasts, the Yanceyville Water Supply Dam serves as a case study in the intricate relationship between infrastructure development, environmental stewardship, and community resilience in the face of evolving challenges.

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.
