Summary
This privately owned earth dam stands at a height of 38 feet and spans a length of 400 feet, creating a reservoir with a storage capacity of 193.1 acre-feet. The dam is situated on a tributary to Mans Fork and is regulated by the Ohio Department of Natural Resources, with regular inspections ensuring its fair condition and low hazard potential.
With a drainage area of 0.34 square miles and a surface area of 8.9 acres, Ohio Power Company Pond Mb-141 Dam plays a crucial role in water resource management in the region. Despite its modest size, the dam has a maximum discharge capacity of 3,064 cubic feet per second, highlighting its importance in flood control and sediment retention. As climate change poses new challenges to water infrastructure, this dam serves as a vital asset in maintaining water quality and availability for both human and ecological needs in the area.
Given its strategic location and regulatory oversight, Ohio Power Company Pond Mb-141 Dam stands as a testament to the collaboration between private entities and state agencies in ensuring the safety and effectiveness of water management structures. As water resource and climate enthusiasts continue to advocate for sustainable practices, this dam exemplifies the balance between human development and environmental stewardship, serving as a model for responsible water infrastructure management in a changing climate.

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.
