Summary
Built in 1975 by DAMES & MOORE, this earth-type dam stands at a height of 70 feet and serves primarily as a water supply source. With a storage capacity of 1485 acre-feet and a surface area of 45 acres, the dam plays a crucial role in maintaining water levels for the surrounding area.
Despite being unregulated by the state and with a low hazard potential, Lake Rabun Dam still undergoes regular inspections to ensure its structural integrity. The dam features uncontrolled spillways and outlet gates, further emphasizing its importance in water management. While it has not been rated in terms of condition assessment, the dam's risk level is considered moderate, highlighting the need for continued monitoring and risk management measures.
Lake Rabun Dam's presence on the K SSITH BRANCH river stream underscores its significance in the regional water supply network. With its history of construction and ongoing maintenance, the dam remains a vital component in the water resource infrastructure of Georgia, serving as a testament to the intersection of engineering, climate resilience, and environmental stewardship in the face of changing climate patterns.

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.
