Summary

Completed in 1959, this Earth-type dam stands at a height of 26 feet and stretches 460 feet in length, with a storage capacity of 70 acre-feet. Despite its low hazard potential, the dam's condition assessment has been rated as poor, posing a potential risk to the surrounding area.

Managed by the South Carolina Department of Health and Environmental Control, Arthur Neely Dam is subject to state regulation, inspection, and enforcement. While the dam has not undergone any significant modifications in recent years, its last inspection in 2017 revealed the need for improvements to ensure its continued safety and functionality. With a designated emergency action plan (EAP) and regular inspection frequency, efforts are being made to address the dam's deteriorating condition and mitigate any potential risks associated with its operation.

Enthusiasts of water resources and climate will find Arthur Neely Dam an intriguing case study, showcasing the complexities of managing aging infrastructure in the face of changing environmental conditions. As discussions around dam safety and maintenance continue, the importance of investing in sustainable water management practices becomes increasingly apparent, highlighting the need for proactive measures to protect both the dam and the surrounding community from potential hazards.

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.
