Summary
The dam, primarily constructed with earth materials, stands at a height of 23 feet and stretches 2410 feet in length. With a storage capacity of 599 acre-feet, the impound serves as a vital water resource for the surrounding area, offering a normal storage capacity of 361 acre-feet.
The dam is situated on Mill Branch, providing a surface area of 43 acres for water storage. Despite being uncontrolled, the spillway type is listed as 'Uncontrolled', with a low hazard potential and moderate risk assessment. The last inspection was conducted in 2002, with a frequency of every 5 years. The dam's condition is currently rated as 'Not Rated', demonstrating a need for further assessment and maintenance to ensure its continued safety and functionality.
Water resource and climate enthusiasts will find Mill Branch Fresh Water Impound an intriguing structure, offering insight into dam construction and management practices. With its historical completion in the early 1990s and moderate risk assessment, there is a clear need for continued monitoring and maintenance to uphold the impound's integrity and safety for both the local community and the environment. As a valuable water resource in Georgia, the impound serves as a reminder of the importance of sustainable water management practices in the face of changing climate conditions.

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.
