Summary

This private-owned earth dam, with a buttress core type, has a storage capacity of 148 acre-feet and covers a surface area of 14 acres. The dam is situated on an unknown river or stream, within the jurisdiction of the state and subject to state inspection.

Despite being classified with a low hazard potential, the dam has a moderate risk assessment score of 3. The last inspection was conducted in October 2017, with an inspection frequency of 5 years. The dam features uncontrolled spillways and outlet gates, while lacking an Emergency Action Plan (EAP) and inundation maps. The condition assessment is listed as "Not Rated," and there is no information available on whether the EAP meets guidelines or if there are updated emergency contacts.

For water resource and climate enthusiasts, Bagley Lake Dam offers a glimpse into the management and maintenance of a recreational dam in Georgia. With its historical significance dating back to the 1950s, the dam presents an opportunity to study the impact of aging infrastructure on water storage and recreational activities. The data provided offers a comprehensive overview of the dam's specifications, purpose, and risk assessment, highlighting the importance of regular inspections and emergency preparedness in ensuring the safety and functionality of such structures.

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.
