Summary

Built in 1940, this earth dam stands at a height of 25 feet and has a hydraulic height of 23.9 feet, providing storage of up to 225 acre-feet of water. With a normal storage capacity of 140 acre-feet and a surface area of 17 acres, the dam serves as a popular spot for outdoor activities in Muscogee County.

Despite being non-state regulated, Flatrock Park Lake Dam undergoes regular inspections to ensure its structural integrity and safety. The dam is classified with a low hazard potential and a moderate risk assessment, highlighting the importance of ongoing risk management measures. With uncontrolled spillways and outlet gates, the dam's overall condition is currently not rated, emphasizing the need for continued monitoring and maintenance to uphold its functionality for recreational purposes.

In the event of an emergency, the dam's emergency action plan status and guidelines compliance remain unspecified. However, with a designated inspection frequency and risk assessment in place, stakeholders can work towards enhancing the safety and resilience of Flatrock Park Lake Dam for the benefit of water resource and climate enthusiasts who frequent the area.

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.
