Summary
Constructed in 1964, this earth dam stands at a height of 55 feet and spans a length of 930 feet, providing a storage capacity of 455 acre-feet. The dam overlooks the tributary to Dyes Fork, ensuring proper drainage within its 0.18 square mile catchment area.
Despite its essential role in water resource management, Ohio Power Company Pond Mm-62 Dam exhibits signs of wear and tear, with a poor condition assessment and a high hazard potential. The last inspection conducted in October 2018 highlighted the urgent need for maintenance and rehabilitation to ensure the safety and functionality of the structure. The Department of Natural Resources in Ohio regulates and inspects the dam periodically to mitigate risks and enforce necessary measures.
As water resource and climate enthusiasts monitor the status of Ohio Power Company Pond Mm-62 Dam, efforts to address its deteriorating condition and enhance its resilience are paramount. With the potential for high hazard consequences in case of failure, collaborative actions between the private owner, regulatory agencies, and stakeholders are essential to safeguard the surrounding community and environment. By implementing risk management measures and prioritizing maintenance, this dam can continue to fulfill its critical role in sustainable water management practices 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.
