Summary
The earth dam, standing at a height of 67 feet and stretching 3400 feet in length, has a storage capacity of 7250 acre-feet of water and covers a surface area of 264 acres. Despite being regulated and inspected by the Georgia Safe Dams Program, the dam is classified as having a high hazard potential, although its current condition is deemed satisfactory.
Managed by a private owner, Imerys 5c Clay Impoundment Dam is designed with a buttress core type and features an uncontrolled spillway system. The dam's associated structures are listed as none, and its hazard potential is considered moderate. While the risk assessment for the dam is rated as a 3 on a scale of 1 to 5, measures for risk management and emergency preparedness are not explicitly outlined in the available data. With its critical role in tailings management and its significant storage capacity, the dam remains a key asset in the water resource infrastructure of the region, warranting ongoing monitoring and maintenance to ensure its continued safety and functionality.

Dam Data Reference
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.
