Summary
Built in 1960, this earth dam stands at a height of 61 feet and spans 680 feet in length, with a storage capacity of 5,265 acre-feet. The dam serves as a key component for water supply purposes in the region, with a normal storage capacity of 3,270 acre-feet and a surface area of 172.8 acres.
Managed by the local government and regulated by the Kentucky Division of Water, Mt Sterling Dam plays a crucial role in controlling water flow along Slate Creek. With a spillway width of 100 feet and a hazard potential rated as significant, the dam has been assessed to be in fair condition as of the last inspection in 2016. Despite moderate risk factors, the dam continues to meet regulatory guidelines and serves as a pivotal structure for water management in Montgomery County, Kentucky.
For water resource and climate enthusiasts, Mt Sterling Dam represents a significant piece of infrastructure that not only ensures water supply for the region but also plays a crucial role in flood control and water management. With its historical significance and ongoing regulatory oversight, the dam stands as a testament to the importance of maintaining and monitoring critical water infrastructure in the face of changing climate patterns and increasing water resource demands.

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.
