Summary
The dam stands at 11 feet high and stretches 563 feet in length, creating a storage capacity of 114 acre-feet. Despite being unregulated by the state, the dam is subject to periodic inspections, with the last one conducted in 2004, revealing a low hazard potential and a moderate risk assessment.
Located in Bleckley County, Hill Lake Dam offers a serene environment for water resource and climate enthusiasts to enjoy recreational activities such as fishing, boating, and wildlife observation. The dam's uncontrolled spillway and outlet gates contribute to its natural setting, while the surrounding surface area of 14 acres provides ample space for outdoor adventures. With its strategic positioning within the Savannah District and a drainage area of 78 square miles, the dam serves as a vital part of the local ecosystem.
Despite its age, Hill Lake Dam remains a resilient structure with no specific condition rating, indicating its sturdy construction. While the dam may not have a formal emergency action plan or inundation maps prepared, its low hazard potential and moderate risk assessment suggest that it continues to function effectively. As water enthusiasts visit this picturesque site, they can appreciate the blend of nature and engineering that sustains the recreational opportunities offered by Hill Lake Dam.

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.
