Summary
Standing at a height of 22.6 feet and with a length of 290 feet, this earth dam offers a normal storage capacity of 45 acre-feet and a maximum storage of 75.6 acre-feet. The dam's low hazard potential and moderate risk assessment make it a relatively safe structure in the region.
Despite being privately owned and not regulated by the state, Tattnall Lake Dam remains a popular destination for outdoor activities such as fishing, boating, and picnicking. The dam's uncontrolled spillway and outlet gates add to its simple yet effective design, providing a serene environment for visitors to enjoy. With its scenic surroundings and moderate risk level, Tattnall Lake Dam offers a unique blend of recreation and safety for those seeking to immerse themselves in Georgia's natural beauty.
As a part of the Charleston District under the US Army Corps of Engineers, Tattnall Lake Dam stands as a testament to responsible dam management and risk assessment. While not currently rated for its condition, the dam's history and purpose as a recreational facility highlight the importance of balancing human enjoyment with environmental safety. For water resource and climate enthusiasts, Tattnall Lake Dam presents an intriguing case study of a privately owned structure that continues to serve its community in a responsible and sustainable manner.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
