Hunters Run Structure No. 3 Reservoir Report
Last Updated: February 21, 2026
Hunters Run Structure No.
Summary
3 is a critical flood risk reduction infrastructure located in Lancaster, Ohio, along the Hunters Run river. Built in 1960 by the USDA NRCS, this earth dam stands at a height of 27.1 feet and spans 1100 feet in length, providing storage capacity of 1781 acre-feet. Despite its age, this dam is still in operation and regulated by the Department of Natural Resources in Ohio, with regular inspections carried out every five years.
The dam's primary purpose is flood risk reduction, and it is designed to handle a maximum discharge of 4010 cubic feet per second. However, recent assessments have shown that the structure is in poor condition with a high hazard potential. With a moderate risk rating of 3, there is a pressing need for maintenance and potential upgrades to ensure the safety and effectiveness of this vital water resource infrastructure. The local government is responsible for overseeing the operation and maintenance of Hunters Run Structure No. 3, and efforts are underway to address the identified issues and mitigate the risks associated with this aging dam.

Dam Data Reference
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.
