Summary

This earth dam, completed in 1994, stands at a structural height of 29.6 feet and has a hydraulic height of 16.6 feet, helping to manage the flow of the 2nd Broad River-Tr and protect the surrounding area from potential flooding. With a storage capacity of 139 acre-feet and a drainage area of 396 square miles, this structure plays a crucial role in safeguarding the community from water-related hazards.

Managed by the local government and regulated by the NCDEQ Dam Safety Program, this dam is inspected regularly to ensure its fair condition and low hazard potential. Despite its modest surface area of 2 acres, the dam serves as a critical asset in the region's water resource management efforts. With a normal storage capacity of 13 acre-feet and a maximum discharge of 1550 cubic feet per second, this structure is designed to handle significant water flow during periods of heavy rainfall, providing peace of mind to residents and stakeholders in the area.

As part of the broader network of water infrastructure in the region, Second Broad Watershed Structure #11-25 exemplifies the intersection of engineering, environmental stewardship, and community resilience. Its strategic placement along the 2nd Broad River-Tr not only mitigates flood risks but also highlights the importance of proactive planning and maintenance in safeguarding our natural resources against the impacts of climate change. For water resource and climate enthusiasts, this structure serves as a tangible example of the critical role that infrastructure plays in promoting sustainability and protecting our communities from the challenges posed by a changing climate.

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.
