Kellner Lake Dam dam
Kellner Lake Dam
Kellner Lake Dam, located in Cobb, Georgia, stands as a pivotal structure for recreational purposes. Completed in 1972, this earth dam reaches a height of 31 feet, with a hydraulic height of 25 feet and a length of 410 feet. The dam boasts a storage capacity of 80 acre-feet, with a normal storage level of 60 acre-feet across its 5-acre surface area. However, recent assessments have classified the dam with a poor condition and high hazard potential, signaling a need for urgent attention and maintenance.
Despite its recreational significance, Kellner Lake Dam's condition assessment and risk potential paint a concerning picture. Inspected last in February 2019, the dam's hazard potential is rated as high, with a moderate risk assessment score of 3. With no Emergency Action Plan (EAP) currently prepared or updated, the dam's management measures and risk mitigation strategies remain unclear. As a private-owned structure, coordination with the Georgia-SAFE DAMS PROGRAM and state regulatory agencies is crucial to ensure the safety and integrity of the dam for both recreational users and the surrounding environment.
As water resource and climate enthusiasts, the data surrounding Kellner Lake Dam highlights the delicate balance between human enjoyment and environmental stewardship. With its poor condition assessment, high hazard potential, and moderate risk assessment, proactive measures are essential to safeguard the dam's structural integrity and prevent any potential disasters. Through collaboration with state agencies and regular inspections, the future of Kellner Lake Dam can be secured for generations to come, ensuring a sustainable and safe recreational environment for all.

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 Kellner Lake Dam
Where does the data for Kellner Lake Dam 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 High 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.
