Summary
The dam, completed in 1966, stands at a height of 35.2 feet and has a storage capacity of 201.1 acre-feet. With a normal storage capacity of 21.1 acre-feet and a surface area of 6 acres, this earth-type dam plays a crucial role in managing water resources in the area.
The dam is regulated and inspected by the Department of Natural Resources in Ohio, ensuring that it meets safety standards. Despite being classified as having a low hazard potential, the condition assessment in 2013 rated it as fair. The dam has a low risk assessment and has not been modified in recent years. Emergency action plans are in place, although they may need updating to meet current guidelines. Overall, the Ohio Power Company Pond Mb-133 Dam serves as an essential infrastructure for water management in the region.
Enthusiasts of water resources and climate in Ohio will find the Ohio Power Company Pond Mb-133 Dam to be a significant structure in the state's water management system. With a rich history dating back to the 1960s, this earth-type dam continues to play a vital role in storing tailings and regulating water flow in the area. The dam's fair condition, low hazard potential, and regular inspections ensure its continued safety and reliability for the community.

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.
