Summary
The dam, standing at a height of 21.9 feet, impounds Mud Creek to create a picturesque lake with a storage capacity of 527 acre-feet. With a surface area of 32 acres, the dam serves as a popular spot for outdoor activities and leisure.
Despite being classified with a low hazard potential and a moderate risk assessment, County Road 80 Lake Dam has not been rated for its condition. The dam features an uncontrolled spillway and outlet gates, and undergoes inspections every five years, with the last inspection conducted in September 2018. Its surroundings remain unlisted or unknown, presenting an opportunity for further exploration and assessment by water resource and climate enthusiasts interested in the ecological impact of such structures on the local environment.
As part of the Mobile District under the U.S. Army Corps of Engineers, County Road 80 Lake Dam offers a unique opportunity for research and study, particularly in understanding the dam's role in water resource management and climate adaptation. With its recreational purpose and scenic setting, the dam presents a valuable case study for investigating the intersection of human development, water conservation, and environmental sustainability in the context of Georgia's rural landscape.

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.
