Summary
Constructed in 1971, this earth dam stands at a height of 12.2 meters and has a hydraulic height of 11 meters, providing storage of 127 acre-feet of water. With a low hazard potential and a moderate risk assessment, the dam's condition is currently not rated, but it undergoes inspections every five years to ensure its safety.
The dam, designed by SCS, features an uncontrolled spillway and outlet gates. It spans a length of 770 meters and covers a surface area of 15 acres, with a drainage area of 1690 acres. While not regulated by the state, the dam is inspected periodically to monitor its integrity. The surrounding area offers recreational opportunities, making Mcmillan Lake Dam a popular destination for water resource and climate enthusiasts seeking a tranquil retreat in the heart of Georgia's natural beauty.
Overall, Mcmillan Lake Dam serves as both a functional water storage and recreational facility, blending engineering ingenuity with natural surroundings to create a harmonious environment for visitors to enjoy. As efforts continue to ensure the dam's safety and maintenance, it stands as a testament to the importance of responsible water resource management in the face of changing climate 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.
