Summary
Managed by BBC&M Engineering, Inc., this earth dam structure stands at 20 feet in height and spans 600 feet in length, with a storage capacity of 49.6 acre-feet. Completed in 1997, this impoundment serves the primary purpose of tailings management, providing storage for up to 36.5 acre-feet of water under normal conditions.
Regulated by the Department of Natural Resources in Ohio, Neutralized Water Impoundment 3 poses a significant hazard potential but is currently assessed to be in satisfactory condition as of the last inspection in November 2019. With a drainage area of 0.01 square miles and a maximum discharge rate of 15 cubic feet per second, this impoundment plays a crucial role in managing water resources in the region. Despite its hazard potential, the structure meets regulatory standards and undergoes inspections every five years to ensure its safety and integrity.
As a vital offstream feature along the Kokosing River, Neutralized Water Impoundment 3 contributes to water resource management in the area by providing storage for tailings and controlling water flow. With its significant storage capacity and satisfactory condition, this private water impoundment stands as a key component of the local water infrastructure, demonstrating effective management and compliance with state regulatory requirements.

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.
