Summary
This private earth dam on Mill Creek stands at a height of 9.4 feet with a normal storage capacity of 51 acre-feet. The dam has a low hazard potential and is currently rated as not assessed for condition, yet it undergoes inspections every 5 years to ensure its safety.
With a drainage area of 2,610 acres, Sheffield Lake Dam offers a surface area of 17 acres for outdoor activities and wildlife habitat. Despite being uncontrolled, the spillway type and outlet gates present a moderate risk with a Hazard Potential of Low. The surrounding beauty of Early County, Georgia, along with the recreational opportunities provided by the dam, make it a valuable asset for residents and visitors alike.
As a significant feature in the local landscape, Sheffield Lake Dam is a testament to the importance of water resource management and climate resilience in the region. Its historical significance, coupled with its recreational and ecological value, highlights the need for continued monitoring and maintenance to ensure the safety and sustainability of this vital water infrastructure for future generations of water resource and climate enthusiasts in 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.
