Summary
Completed in 1991, this earth dam stands at a height of 18 feet and spans 460 feet in length along the U.T. Dry Run river. Its primary purpose is flood risk reduction, with a storage capacity of 78 acre-feet and a normal storage level of 10 acre-feet.
Managed by the Kentucky Division of Water, Toyota Dam has a low hazard potential and a moderate risk rating. Despite not being rated for its condition, the dam has undergone inspections every five years, with the last recorded inspection taking place in June 2006. With an uncontrolled spillway type, the structure serves as a vital component in managing water resources and mitigating flood risks in the region.
Located in a rural area with no designated town, Toyota Dam plays a crucial role in protecting the surrounding area from potential flooding events. As an integral part of the flood risk reduction infrastructure in Kentucky, this dam showcases the collaboration between private ownership and state regulatory agencies in safeguarding water resources and climate resilience in the region.

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.
