Summary
This private earth dam, designed by the SCS, stands at a height of 17 feet with a hydraulic height of 21 feet, providing a storage capacity of 130 acre-feet. The dam spans a length of 750 feet and covers a drainage area of 95 acres, with a surface area of 10 acres.
With a low hazard potential and a moderate risk assessment rating, Lewis Lake Dam has not been rated for its condition assessment as of yet. The dam features uncontrolled spillways and outlet gates, and the last inspection was conducted in December 2004. Despite being privately owned, the dam is regulated by the state and subject to periodic inspections to ensure its structural integrity and safety compliance.
Situated within the Savannah District, Lewis Lake Dam is a vital water resource structure in the region, contributing to agricultural irrigation and water storage needs. Although not federally owned or funded, the dam plays a crucial role in water management in the area. Enthusiasts of water resources and climate will find Lewis Lake Dam a fascinating example of private dam infrastructure in Georgia, showcasing the importance of maintaining and monitoring such structures for sustainable water usage and environmental protection.

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.
