Summary
Completed in 1966, this earth dam stands at a height of 76 feet and spans 700 feet, providing crucial flood protection for the surrounding area. With a normal storage capacity of 4137 acre-feet and a maximum discharge of 19948 cubic feet per second, the dam plays a crucial role in managing water resources in the region.
Managed by the Ohio Department of Natural Resources, Wolf Run Lake Dam is subject to state regulations, inspections, and enforcement to ensure its structural integrity and public safety. Despite being classified as having a high hazard potential, the dam's condition assessment indicates it is currently in fair condition. Its risk assessment is moderate, signaling the need for ongoing monitoring and management measures to address any potential risks. With a capacity of 7737 acre-feet and a surface area of 214 acres, the dam serves as a key infrastructure for water resource management and flood protection in the area.
In the event of an emergency, the dam's Emergency Action Plan (EAP) is prepared to meet guidelines and ensure the safety of nearby residents. With Bill Johnson (R) as the congressional representative for the area, the Wolf Run Lake Dam stands as a critical piece of infrastructure that underscores the importance of effective water resource and climate management in mitigating flood risks and safeguarding communities.

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.
