Summary
Rose Priory, Marion, Kentucky. Completed in 1966, the dam primarily serves the purpose of tailings storage, with a height of 30 feet and a length of 330 feet. The dam has a storage capacity of 76.9 acre-feet, with a normal storage level of 46.8 acre-feet, covering a surface area of 5.2 acres and draining a 0.26 square mile watershed of TR-Cartwright Creek.
Despite its significant hazard potential and poor condition assessment, the dam is regulated by the Kentucky Division of Water and undergoes regular inspections, with the last one conducted in December 2016. The spillway is uncontrolled with a width of 20 feet, posing a moderate risk level. The dam's emergency action plan status, inundation maps, and risk management measures are currently undisclosed. With its unique location and history, Montgomery Dam stands as a vital structure in managing water resources in the region and warrants continued monitoring and maintenance for safety and sustainability.

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.
