Summary

Managed by the Natural Resources Conservation Service, this dam serves primarily for recreational purposes with a maximum storage capacity of 85 acre-feet. With a height of 18 feet and a hydraulic height of 17 feet, the dam spans 396 feet in length and covers an area of 9 acres.

Despite being unregulated by the state, Suwanee Bogging Hole Lake Dam has a low hazard potential and is currently in a not rated condition as of its last inspection in 1989. The dam features an uncontrolled spillway and outlet gates, with a moderate risk assessment of level 3 associated with its operation. Although the dam has not been modified in recent years and lacks a formal emergency action plan, it continues to provide a safe and enjoyable recreational environment for enthusiasts in the region.

Enthusiasts of water resources and climate will find Suwanee Bogging Hole Lake Dam to be an interesting feature in the Savannah District. Its private ownership and emphasis on recreation make it a unique structure in the area, offering opportunities for boating, fishing, and other outdoor activities. While the dam's condition and risk factors are being monitored, visitors can still enjoy the beauty of the surrounding landscape and the tranquility of the lake created by this earth dam.

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.
