Summary
Built in 1870, this earthen dam stands at a height of 9 feet and has a hydraulic height of 10 feet, creating a storage capacity of 1,090 acre-feet. With a surface area of 83 acres, this dam serves primarily for recreational purposes and is situated on the picturesque Ten Mile Creek.
Although the dam is classified as having a low hazard potential and a moderate risk assessment, it has not been rated for its current condition. The last inspection took place in May 2016, with a scheduled inspection frequency of every 5 years. The dam features uncontrolled spillways and outlet gates, and while it is not regulated by the state or federal agencies, it is subject to state jurisdiction and inspection.
Water resource and climate enthusiasts will find Averys Mill Pond to be a charming and historic site for recreational activities in Georgia. With its serene surroundings and moderate risk profile, this dam offers a glimpse into the rich history of water management and conservation efforts in the region. While the dam may not be currently rated for its condition, its low hazard potential and ongoing state inspection provide reassurance for visitors seeking a peaceful escape in nature.

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.
