Summary
This earth dam, with a height of 18 feet and a storage capacity of 269 acre-feet, plays a crucial role in regulating water levels and providing recreational opportunities at McDuffie P.F.A. Lake. Despite being classified as having a low hazard potential, the dam is regularly inspected and maintained to ensure its safety and functionality.
The dam's primary purpose is listed as "Other," indicating its multifaceted role in water management and conservation efforts. With a moderate risk assessment rating, the dam is deemed to have a moderate level of risk associated with its operation and potential hazards. While the condition assessment is currently marked as "Not Rated," the dam's inspection frequency of 5 years ensures that any issues are promptly identified and addressed. Additionally, the presence of uncontrolled spillways and outlet gates highlights the importance of proper monitoring and maintenance to prevent any potential risks or emergencies.
As part of the state-owned water infrastructure, Dearing # 11 Lake Dam is a key component in the overall water management strategy for the region. Its location in the vicinity of Poplar Head underscores its significance in providing water resources for both recreational and environmental purposes. With its historical significance and ongoing maintenance efforts, this dam continues to play a crucial role in water resource management and climate resilience in McDuffie, Georgia.

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.
