Summary
This privately owned earth dam stands at a height of 28.4 feet with a hydraulic height of 22.4 feet, creating a reservoir with a maximum storage capacity of 156 acre-feet. With a surface area of 13 acres and a drainage area of 205 square miles, the dam provides a picturesque setting for water enthusiasts to enjoy various recreational activities.
Despite being categorized as having a low hazard potential, the dam has a moderate risk assessment rating of 3, signaling the need for ongoing monitoring and risk management measures. The last inspection conducted in July 2019 found the dam's condition to be not rated, highlighting the importance of regular assessments to ensure its structural integrity and safety. While the dam is equipped with uncontrolled spillways and outlet gates, it does not have a state regulatory agency overseeing its operations or permitting requirements.
Lake Constance Dam, nestled in the beautiful landscape of Georgia, offers a tranquil retreat for water resource and climate enthusiasts to appreciate the intersection of human engineering and natural beauty. As a vital part of the local ecosystem and community, the dam serves as a reminder of the delicate balance between water management for recreation and the need for effective risk assessment and management to ensure its continued safety and functionality.

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.
