Summary

Completed in 1965 by CESAM, this Gravity type dam serves multiple purposes including flood risk reduction, hydroelectric power generation, recreation, and water supply. With a hydraulic height of 170 feet and a structural height of 188 feet, the dam spans 125 feet in length and has a storage capacity of over 670,000 acre-feet.

Managed by the US Army Corps of Engineers, Allatoona Dam is crucial for managing flood risks along the Etowah River. The dam's high hazard potential necessitates frequent inspections and a prepared Emergency Action Plan (EAP) to mitigate risks and ensure public safety. With a risk assessment rating of "Very High", the USACE implements various risk management measures, including regular monitoring, maintenance, and collaboration with local emergency managers to address potential dam-related emergencies and ensure the dam's structural integrity.

Despite the inherent risks associated with dam operations, the USACE remains committed to safeguarding Allatoona Dam and the surrounding community by implementing proactive strategies to manage flood risks and ensure the dam's functionality. As part of ongoing efforts to enhance risk management practices, more detailed information specific to Allatoona Dam will be provided in the future to further strengthen emergency preparedness and response capabilities in the region.

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. 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

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, 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.
