Summary

The dam, designed by Mr. Mahony, stands at a height of 33 feet and spans a length of 767 feet, holding a storage capacity of 1579 acre-feet. Despite its primary function for recreation, the dam poses a high hazard potential and is rated in poor condition as of the last inspection in March 2019.

Located in Rockdale County, the dam's surrounding area covers 75 acres with a drainage area of 948 square miles. It is regulated by the state's Safe Dams Program, which oversees its inspection, permitting, and enforcement activities. With a moderate risk assessment score of 3, the dam's risk management measures and emergency preparedness status remain unspecified, indicating a need for continued monitoring and maintenance to ensure public safety and environmental conservation.

For water resource and climate enthusiasts, Lake Rockdale Dam presents an intriguing case study of a privately owned earth dam with buttress core types, serving primarily for recreation but also carrying significant safety risks. Its presence in the landscape of Conyers, Georgia, underlines the importance of regular inspections, condition assessments, and risk management practices to safeguard both human life and the surrounding ecosystem from potential hazards associated with dam failure.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
