Summary

Built in 1987 by the USDA NRCS, this earth dam stands at a structural height of 38.5 feet and a hydraulic height of 16 feet. With a normal storage capacity of 156 acre-feet and a maximum discharge of 3,733 cubic feet per second, the dam plays a crucial role in managing water flow in the region.

The Second Broad River WS Dam #4 is regulated by the NCDEQ Dam Safety Program and undergoes regular inspections to ensure its fair condition and significant hazard potential are managed effectively. Despite its age, the dam continues to meet guidelines for emergency action preparedness and risk assessment, with a moderate risk level of 3. With a drainage area of 2,093 acres and a storage capacity of 1,652 acre-feet, the dam provides essential flood protection for the surrounding areas while also offering recreational opportunities and habitat for wildlife.

As water resource and climate enthusiasts, it is important to recognize the Second Broad River WS Dam #4 as a vital piece of infrastructure that not only protects against floods but also contributes to the overall health and sustainability of the ecosystem. With ongoing monitoring and management, this dam exemplifies the intersection of human engineering and environmental stewardship in ensuring the resilience of our water resources in the face of changing climate conditions.

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.
