Summary

This earth dam, completed in 1994, stands at a structural height of 34.5 feet with a hydraulic height of 20.6 feet, offering protection to the surrounding area with a drainage area of 220 square miles. With a normal storage capacity of 12 acre-feet and a maximum storage of 110 acre-feet, this dam plays a crucial role in managing water resources in the region.

Owned and regulated by the local government, this structure is under the oversight of various state agencies including NCDEQ's Dam Safety Program. Despite being classified as low hazard potential, it received a fair condition assessment during its most recent inspection in March 2021. With a solid emergency action plan in place and regular inspections every five years, the community can rest assured of its safety and efficient flood risk reduction capabilities. As an essential part of the watershed infrastructure, Second Broad Watershed Structure 11-24b continues to serve its primary purpose effectively, showcasing the importance of sustainable water resource management in the face of changing climate patterns.

With its strategic location, effective design, and state-regulated operations, Second Broad Watershed Structure 11-24b stands as a testament to the importance of flood risk reduction infrastructure in mitigating the impacts of climate change on water resources. As climate enthusiasts and water resource advocates, we can appreciate the role this dam plays in protecting the community and managing water flow along the 2nd Broad River-Tr. By staying vigilant, maintaining good condition, and adhering to regulatory guidelines, this structure exemplifies the resilience and adaptability needed in the face of evolving environmental challenges.

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.
