Atlanta Country Club Lake Dam No. 18 dam
Atlanta Country Club Lake Dam No. 18
Atlanta Country Club Lake Dam No. 18, located in Marietta, Georgia, is a privately owned earth dam completed in 1965 for recreational purposes. Standing at a height of 41.5 feet with a hydraulic height of 25 feet, this dam boasts a normal storage capacity of 30 acre-feet and covers a surface area of 3 acres. The dam, managed by the GA-SAFE DAMS PROGRAM, is regulated and inspected by the state of Georgia, ensuring its structural integrity and safety for the surrounding community.
With an undetermined hazard potential and a satisfactory condition assessment as of September 2019, Atlanta Country Club Lake Dam No. 18 presents a moderate risk level. Despite having uncontrolled spillways and outlet gates, the dam has not been modified over the years. The last inspection in September 2019 indicated no immediate concerns, showcasing the diligent maintenance efforts put in place to mitigate any potential risks associated with the dam.
For water resource and climate enthusiasts, Atlanta Country Club Lake Dam No. 18 serves as a focal point for recreation in the Cobb County area. Its serene surroundings and well-maintained structure provide a safe and enjoyable environment for water-based activities. The collaboration between private ownership and state regulatory agencies ensures that this dam continues to fulfill its purpose while adhering to safety standards and environmental conservation efforts.
Dam data reference
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.
- 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.
- 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.
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, environmental 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.

About Atlanta Country Club Lake Dam No. 18
Where does the data for Atlanta Country Club Lake Dam No. 18 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Undetermined hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
