Summary

Constructed in 1969 by the Natural Resources Conservation Service, this structure stands at a height of 36 feet and has a length of 480 feet, providing a storage capacity of 1056 acre-feet. Despite being uncontrolled, the dam has a low hazard potential and a moderate risk assessment rating.

This dam, managed by the State of Georgia, has not been regulated or permitted by any state agency. However, it undergoes regular inspections, with the last one conducted in June 2016. With no condition assessment rating available, the structure's overall condition remains unknown. Although lacking an emergency action plan, the risk of failure is considered moderate, highlighting the importance of implementing risk management measures to ensure public safety and the protection of downstream areas.

Middle Oconee-Walnut Creek WS Structure #12, nestled within the Savannah District, serves as a crucial flood risk reduction infrastructure in the region. With its strategic location and design features, this dam plays a vital role in managing water resources and mitigating potential flood hazards. As water resource and climate enthusiasts, understanding the significance and condition of such structures is essential for sustainable water management practices and preparedness for any emergency situations that may arise.

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.
