Summary
This private-owned earth dam, with a structural height of 22 feet, stores 94 acre-feet of water and covers a surface area of 8 acres. The dam is situated on the TRIB-POMME DE TERRE stream and is not regulated by the state, but it has a high hazard potential.
Despite being last inspected in 1980 and not having a current condition assessment, Hardeke Lake Dam remains a popular spot for water resource and climate enthusiasts. With a drainage area of 190 square miles, the dam provides essential water storage for recreational activities and supports the surrounding ecosystem. As a private-owned structure, it is crucial for the owners to ensure proper maintenance to mitigate any potential risks associated with the high hazard potential of the dam.
While the dam may not have recent inspection data or a condition rating, its historical significance and role in providing recreational opportunities make it an important landmark in Greene County, Missouri. As enthusiasts continue to appreciate the beauty and functionality of Hardeke Lake Dam, there is a growing need for updated assessments and risk management measures to maintain the safety and integrity of this valuable water resource.

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.
