Summary
Designed by Proctor, Davis, and Ray from Lexington, KY, this earth dam stands at a height of 78 feet and stretches 1700 feet in length, creating a reservoir with a normal storage capacity of 2888 acre-feet and a total surface area of 125.5 acres. The dam is regulated, permitted, inspected, and enforced by the Kentucky Division of Water, ensuring its safety and compliance with state regulations.
The Fagan Branch Dam poses a high hazard potential and has been assessed to be in fair condition as of September 2017. With a moderate risk level, emergency action plans for the dam are not disclosed, and the inundation maps are not prepared. The dam features an uncontrolled spillway with a width of 25 feet and is situated along the Fagan Branch of Rolling Fork River. Maintained by the local government, this crucial water resource infrastructure plays a vital role in providing water supply to the surrounding area, serving as a key asset for water resource and climate enthusiasts to study and appreciate.

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.
