Summary
R. Holder's Dam, also known as Powerline Pond, is a private earth dam located in Milledgeville, Georgia, along Beaverdam Creek. Built in 1970 by the Natural Resources Conservation Service, this dam serves primarily as a Fish and Wildlife Pond, with additional purposes including Fire Protection, Stock, Recreation, and small fish pond uses. With a height of 30 feet and a length of 240 feet, the dam has a storage capacity of 58 acre-feet and a maximum discharge of 120 cubic feet per second.
This Low hazard dam has a moderate risk assessment rating of (3) and has not had a recent condition assessment available. Despite its limited surface area and drainage area of 0.12 square miles, J. R. Holder's Dam is a crucial water resource for the local ecosystem, providing habitat for fish and wildlife. While not regulated by the state, the dam is maintained by the USDA NRCS and has not had any recent inspections or emergency preparedness measures in place. For water resource and climate enthusiasts, this dam presents an opportunity to explore the intersection of human infrastructure and environmental conservation in a rural Georgia setting.

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.
