Summary
Owned privately, this dam has a primary purpose of providing a serene environment for outdoor activities. It reaches a height of 13 feet and has a maximum storage capacity of 180 acre-feet, with a normal storage level of 80 acre-feet across its 765-foot length.
Despite being unregulated by the state, Brown Lake Dam poses a low hazard potential and has a moderate risk assessment rating. While the condition assessment is currently not rated, the dam undergoes inspections every five years. With an uncontrolled spillway and outlet gates, this dam is designed for recreational use rather than flood control or water resource management. The surrounding Macon County area offers a tranquil setting for those seeking solace in nature.
In the care of private ownership, Brown Lake Dam remains a charming destination for outdoor enthusiasts seeking a peaceful retreat. With its modest risk level and low hazard potential, this Earth dam serves primarily as a recreational spot along Mill Creek. As water resource and climate enthusiasts explore the Macon, Georgia area, Brown Lake Dam provides an opportunity to connect with nature and enjoy the beauty of the surrounding landscape.

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.
