Summary

Built in 1968, this earth dam stands at a height of 43 feet and spans a length of 1050 feet, creating a lake with a storage capacity of 475 acre-feet. Despite its primary purpose for recreation, the dam's significant hazard potential and poor condition assessment in 2018 highlight the need for ongoing monitoring and maintenance efforts.

Managed by the local government, Long Run Park Lake Dam falls under the regulatory oversight of the Kentucky Division of Water. With a spillway width of 25 feet and uncontrolled spillway type, the dam faces moderate risk, prompting the need for detailed risk assessments and management measures. Given its location in a densely populated area, it is crucial for emergency preparedness plans to be in place to mitigate any potential hazards and ensure public safety.

Climate and water resource enthusiasts will find Long Run Park Lake Dam an intriguing case study, showcasing the intersection of recreational infrastructure, environmental regulation, and risk management. The dam's historical significance, coupled with its current maintenance challenges, offer valuable insights into the complexities of managing water resources in urban environments and the importance of proactive stewardship to safeguard both recreational amenities and public safety.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
