Summary
Built in 1972 by HARRY BALKE ENGINEERS from Cincinnati, Ohio, this earth dam stands at a height of 64 feet and stretches 535 feet in length. The dam serves the primary purpose of water supply, with a storage capacity of 504 acre-feet and a surface area of 21.1 acres.
Despite its important role in water resource management, Old Man's Cave Lake Dam has been classified as having a high hazard potential and poor condition assessment. The last inspection in October 2017 revealed the need for improvement. The dam is regulated by the Department of Natural Resources in Ohio and undergoes regular inspections, with a frequency of every 5 years to ensure its safety and integrity.
Located in SOUTH BLOOMINGVILLE and acting as a tributary to Queer Creek, Old Man's Cave Lake Dam poses a significant risk in case of failure. With its key role in water supply for the area, efforts are being made to address its poor condition and ensure that it meets safety guidelines and regulations. For water resource and climate enthusiasts, the management and maintenance of Old Man's Cave Lake Dam present a critical challenge in ensuring the safety and sustainability of water infrastructure in Ohio.

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.
