Summary

This earth dam was completed in 1960 and serves primarily for tailings storage purposes, with a height of 59.2 feet and a storage capacity of 3802 acre-feet. The dam is regulated by the Department of Natural Resources and undergoes regular inspections to ensure its fair condition and significant hazard potential are managed effectively.

Situated on Brannon Fork, this dam plays a crucial role in water resource management in the region, with a drainage area of 3.92 square miles and a maximum discharge capacity of 1182 cubic feet per second. The dam's fair condition assessment in 2018 highlights the ongoing need for maintenance and monitoring to mitigate potential risks. Despite its age, Ohio Power Company Pond Mb-46 Dam continues to provide essential water storage and flood control benefits for the surrounding area, making it a key component of the local hydrological infrastructure.

With its unique location and significant hazard potential, Ohio Power Company Pond Mb-46 Dam serves as a vital structure in Ohio's water resource network. As climate change impacts continue to affect the region, maintaining and enhancing the resilience of this dam will be essential to ensure its continued functionality and safety for both the local community and the environment. By adhering to state regulations and conducting regular inspections, the owners and regulators can work together to address any potential risks and ensure the long-term sustainability of this important water management facility.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
