Summary
This private-owned earth dam stands at 33 feet high with a hydraulic height of 10 feet, providing a maximum storage capacity of 279 acre-feet. Despite its uncontrolled spillway and low hazard potential, the dam has not been rated for its condition, highlighting the need for regular inspections to ensure its continued safety and functionality.
Managed by the NCDEQ Dam Safety Program, Third Creek Dam #10 falls under state jurisdiction and regulation, with a state-mandated inspection frequency of 5 years. The dam's primary purpose is flood risk reduction, aligning with its design as an earth structure with stone core and soil foundation. With a moderate risk assessment of 3, steps for risk management and emergency action planning are crucial aspects that need attention to enhance the dam's resilience to potential hazards. As water resource and climate enthusiasts, understanding the significance of maintaining and monitoring dams like Third Creek Dam #10 is essential for safeguarding communities and ecosystems in the face of changing environmental conditions.

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.
