Summary

Owned by the local government, this earth dam stands at a height of 20.2 feet and has a maximum storage capacity of 132 acre-feet. With a surface area of 18.8 acres and a drainage area of 460 square miles, City Lake Dam serves as a picturesque spot for outdoor activities and water recreation.

Despite its low hazard potential, the dam has not been rated for its condition as of the last inspection in April 2017. While it is not state-regulated, City Lake Dam undergoes regular inspections every five years to ensure its structural integrity and safety. The dam features uncontrolled spillways and outlet gates, contributing to its moderate risk level of 3. Although it has not been modified in recent years, the dam remains a popular destination for locals and tourists seeking water-based leisure activities.

With its tranquil setting and ample storage capacity, City Lake Dam continues to be a cherished landmark in Fulton County, Georgia. As climate change impacts water resources and ecosystems, the maintenance and monitoring of dams like City Lake are crucial to safeguarding the surrounding environment and ensuring public safety. Whether for fishing, boating, or simply enjoying the scenic views, City Lake Dam provides a valuable recreational resource while also serving as a reminder of the importance of responsible water management in the face of a changing climate.

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.
