Summary
The dam has a storage capacity of 276 acre-feet and serves as a low hazard structure with a moderate risk assessment. It has an uncontrolled spillway and outlet gates, making it a vital piece of infrastructure for water resource management in the area.
Despite being privately owned, Sadie Lake Dam falls under the jurisdiction of the state of Georgia and undergoes regular inspections. The dam's last inspection was in May 2017, with an inspection frequency of every 5 years. The condition assessment is currently listed as "Not Rated," indicating the need for further evaluation to ensure the dam's safety and integrity for both water resource management and climate conservation efforts.
With a risk assessment rating of moderate, Sadie Lake Dam is an important structure for maintaining water storage and flood control in the region. While it may not be regulated by the state, its presence is crucial for managing water resources and mitigating potential risks associated with dam failure. As water resource and climate enthusiasts, it is essential to monitor and support the upkeep of structures like Sadie Lake Dam to ensure the sustainable management of water in the area.

Dam Data Reference
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.
