Summary

With a hydraulic height of 21.6 feet and a structural height of 23.7 feet, this dam serves primarily for recreational purposes, offering a storage capacity of 38 acre-feet and covering a surface area of 4.7 acres. Despite its fair condition assessment as of February 2021, Green Dam is classified as having a high hazard potential.

Managed by the North Carolina Department of Environmental Quality and the Division of Energy, Mineral, and Land Resources Dam Safety Program, Green Dam is subject to state regulation, permitting, inspection, and enforcement. The dam's last inspection in February 2021 indicated a need for regular monitoring and maintenance to ensure its safety and functionality. Despite its critical importance for recreation, Green Dam presents a potential risk factor that requires continuous assessment and management measures to mitigate any potential hazards and ensure the safety of surrounding communities and the environment.

As water resource and climate enthusiasts, it is crucial to recognize the significance of dams like Green Dam in providing recreational opportunities and water storage. However, it is equally important to stay informed about their condition, potential risks, and regulatory oversight to advocate for their proper maintenance and management. By understanding the complexities of dam infrastructure and the potential hazards they pose, enthusiasts can contribute to the sustainable use of water resources and the protection of communities and ecosystems.

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.
