Summary
The dam, with a height of 16 feet and a length of 724 feet, impounds Yellow Creek, creating a reservoir with a normal storage capacity of 2,274 acre-feet. The dam is primarily regulated by the Ohio Department of Natural Resources and is inspected regularly to ensure its safety and functionality.
Despite its age, Pine Lake Dam has been assessed as being in satisfactory condition, with a high hazard potential due to its location near populated areas. The dam has an emergency action plan in place, although the details of its last revision and compliance with guidelines are not provided in the available data. With a drainage area of 3.86 square miles and a maximum discharge capacity of 13,106 cubic feet per second, Pine Lake Dam plays a vital role in managing water resources and mitigating flood risks in the region.
As a public utility-owned structure, Pine Lake Dam represents a significant piece of infrastructure that supports the water supply needs of Mahoning County, Ohio. With its historical significance and ongoing regulatory oversight, the dam stands as a testament to the importance of sustainable water resource management in the face of changing climates and growing population demands.

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.
