Summary
Built in 1958, this earth dam stands at a hydraulic height of 9 feet and a structural height of 33 feet, with a length of 630 feet. With a maximum storage capacity of 236 acre-feet and a normal storage capacity of 33 acre-feet, the dam serves a critical role in mitigating flood risks in the area.
The dam, regulated by NCDEQ and inspected regularly, has a fair condition assessment as of December 2020. It has a high hazard potential and a moderate risk assessment. The spillway type is uncontrolled, and the outlet gates are also uncontrolled. Despite its age, Third Creek Dam #9 continues to play a vital role in protecting the surrounding community and infrastructure from potential flooding events.
With its historical significance and ongoing importance in flood risk reduction efforts, Third Creek Dam #9 stands as a testament to the successful collaboration between private owners and governmental agencies in ensuring the safety and security of water resources in the region. As climate change continues to impact weather patterns and increase the frequency of extreme weather events, the role of dams like Third Creek Dam #9 in safeguarding communities becomes increasingly vital.

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.
