Summary
Standing at a height of 25.5 feet with a hydraulic height of 21 feet, the dam stretches 370 feet in length and has a maximum storage capacity of 30 acre-feet. Despite its low hazard potential, the dam serves a vital role in managing water resources and protecting against erosion in the area.
With a surface area of 13 acres and a drainage area of 253 square miles, Hall Dam plays a key role in regulating the flow of water and maintaining the ecological balance of the region. Although the dam is currently not rated for condition assessment and lacks an Emergency Action Plan (EAP), its moderate risk assessment indicates the need for ongoing monitoring and management measures to ensure its long-term safety and functionality. Additionally, the dam's uncontrolled spillway and lack of outlet gates highlight the importance of regular inspection and maintenance to prevent any potential risks or emergencies.
While Hall Dam may not be as well-known as other major water infrastructure projects, its significance lies in its contribution to grade stabilization and water resource management in the Macon area. As climate change continues to impact water availability and quality, the role of dams like Hall Dam becomes increasingly crucial in safeguarding communities and ecosystems against the threats of flooding and erosion. Enthusiasts of water resources and climate resilience can appreciate the importance of Hall Dam in balancing human needs with environmental protection and sustainability.

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.
