Summary

Built in 1967, this earth dam stands at a height of 35 feet with a length of 620 feet, providing a maximum storage capacity of 827 acre-feet. The dam serves the primary purpose of flood risk reduction along the Dosters Creek, with a low hazard potential and a moderate risk assessment rating.

Owned by the state of Georgia and designed by the Natural Resources Conservation Service, Middle Oconee-Walnut Creek WS Structure # 18 is not regulated by the state and does not require permitting. The dam has not been inspected since June 2016, with an inspection frequency of every 5 years. Despite being in a not rated condition, the structure meets the guidelines for emergency action plans and risk management measures, ensuring the safety of the surrounding community in case of flooding events. Located within the Mobile District of the US Army Corps of Engineers, this dam contributes to the overall water resource management in the area and showcases the collaborative efforts between local and state agencies in mitigating flood risks.

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.
