This Earth-type dam, with a height of 57 feet and a storage capacity of 5545 acre-feet, serves a high hazard potential yet maintains a satisfactory condition assessment. The dam, located in the Nashville District, is crucial for water resource management in the region.
Despite its uncontrolled spillway and outlet gates, Lower Haig Mill Reservoir Dam has been deemed to have moderate risk, with emergency preparedness measures in place. The dam's last inspection in March 2017 revealed a satisfactory condition, although it is categorized as a high hazard potential structure. With its strategic location and storage capacity, the dam plays a crucial role in water supply and management in the area.
Lower Haig Mill Reservoir Dam's importance lies in its role as a key water resource infrastructure in Whitfield, Georgia. With state regulation, inspection, and a moderate risk assessment, the dam ensures water supply reliability while also addressing safety concerns. As climate change impacts water availability, the dam's management and maintenance become increasingly critical for sustainable water resource management in the region.

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.
