Summary

The dam was completed in 1957 and has a height of 22 feet and a length of 500 feet. It serves as a crucial structure along the TR-KNOB CREEK river, with a normal storage capacity of 43.3 million gallons and a maximum storage capacity of 80 million gallons.

Managed by the Kentucky Division of Water, Bennett Dam is regulated, inspected, and enforced by the state to ensure its structural integrity and safety. Despite its low hazard potential, the dam's condition assessment is rated as poor as of the last inspection in April 2018. The risk assessment for the dam is moderate, indicating potential vulnerabilities that may need to be addressed in the future.

With its unique design as an earth dam and uncontrolled spillway type, Bennett Dam stands as a significant water resource structure in the region. Water resource and climate enthusiasts may find interest in the dam's history, construction, and ongoing management to ensure its continued functionality and safety for the surrounding community and ecosystem.

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.
