Summary
Managed by the Natural Resources Conservation Service, this dam stands at a height of 13.1 feet with a storage capacity of 288 acre-feet. The dam overlooks the Hood Branch river and has a surface area of 35 acres, providing essential water resources for the surrounding area.
Despite its moderate risk assessment rating, the condition of Griffin Lumber Company Lake Dam has not been officially rated, with inspection and maintenance measures yet to be determined. The dam features an uncontrolled spillway and outlet gates, presenting an element of hazard potential that has yet to be fully assessed. While the dam's emergency action plan status and risk management measures are not currently available, its strategic location and purposeful design make it a crucial asset for water resource management and climate resilience in the region.
As a key player in the irrigation infrastructure of Morgan, Georgia, Griffin Lumber Company Lake Dam serves as a vital link in the water supply chain. With its historical significance and essential function, the dam presents an opportunity for enhanced monitoring and risk mitigation strategies to ensure its continued effectiveness in supporting agricultural and environmental needs in the area.

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.
