Summary
Owned privately, the dam stands at a height of 13.8 feet with a hydraulic height of 13.2 feet. It has a length of 640 feet and a storage capacity of 86.8 acre-feet, providing essential water resources to the surrounding area.
While the dam has a low hazard potential and is currently in a not rated condition, its risk assessment is moderate. The dam features an uncontrolled spillway and outlet gates. Although it is not regulated by the state and does not require permits or inspections, the dam plays a crucial role in water management and conservation in the region. Water resource and climate enthusiasts will find Gray Lake Dam to be an interesting case study in private dam ownership and its impact on local water systems.
Overall, Gray Lake Dam stands as a testament to the importance of small-scale water infrastructure for various community needs. Its construction by the SCS and lack of state regulation highlight the diverse landscape of water resource management in Georgia. As climate change continues to affect water availability and quality, understanding the role of dams like Gray Lake in local ecosystems becomes increasingly vital for sustainable water resource management.

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.
