Summary
This private earth dam stands at a height of 18 feet and stretches 6400 feet in length, with a storage capacity of 650 acre-feet. Despite being unlisted by the US Army Corps of Engineers, the dam has a low hazard potential and a moderate risk assessment rating.
The dam is not regulated by the state but undergoes inspections every five years, with the last assessment conducted in January 2018. It features uncontrolled spillways and outlet gates, with no associated locks. The surrounding area has a surface area of 55 acres and a drainage area of 56 acres. With a normal storage capacity of 331 acre-feet, the dam plays a crucial role in managing tailings and ensuring water resource sustainability in the region.
While Engelhard Holliman #1 Finishing Pond Dam may not be widely recognized, its contribution to water resource management in Georgia is significant. As climate change continues to impact water availability, it is essential to monitor and maintain such structures to safeguard against potential risks. With its low hazard potential and moderate risk assessment, this dam serves as a valuable asset in the region's water infrastructure.

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.
