Summary
This earth dam serves primarily for recreational purposes, providing a storage capacity of 78 acre-feet and covering a surface area of 7.4 acres. Despite its low hazard potential and satisfactory condition assessment, the dam is regulated by the Kentucky Division of Water and undergoes regular inspections.
Designed by P&A Engineers and Consultants, Inc., Seven N Lake Dam is equipped with an uncontrolled spillway and is situated within the Louisville District of the US Army Corps of Engineers. The dam's risk assessment indicates a moderate level of risk, reflecting the importance of ongoing risk management measures. While the dam has not been modified in recent years, its emergency action plan and inundation maps are yet to be fully prepared, highlighting areas for improvement in emergency response readiness.
Enthusiasts of water resources and climate will find Seven N Lake Dam to be an intriguing case study in dam infrastructure management and the intersection of recreational and regulatory considerations. Its location in a picturesque setting in Kentucky, combined with its unique design features and risk profile, make it a compelling site for further exploration and analysis in the realm of water resource management and climate resilience.

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.
