Summary
With a height of 23.5 feet and a length of 350 feet, this dam serves to control water flow and protect the surrounding area from potential inundation. Despite its important role in safeguarding the community, the dam is currently assessed as being in poor condition with a high hazard potential, highlighting the need for maintenance and repair to ensure its continued effectiveness.
Managed by the Department of Natural Resources and regulated by the state of Ohio, Hunters Run Structure R-42 is subject to regular inspections to monitor its structural integrity and hazard potential. The dam has a storage capacity of 22 acre-feet and a drainage area of 0.14 square miles, making it a crucial component of the local flood control infrastructure. Although the risk assessment for this dam is moderate, efforts to address its poor condition and ensure its long-term viability are essential to mitigate potential threats to public safety and water resource management in the region.
As water resource and climate enthusiasts, it is imperative to recognize the significance of infrastructure like Hunters Run Structure R-42 in protecting communities and ecosystems from the impacts of flooding. By advocating for the necessary investments in maintenance and rehabilitation of critical dams like this one, we can contribute to resilient water management systems that are essential for addressing the challenges posed by a changing climate. The collaboration between state agencies, federal designers, and local governments is crucial in ensuring the sustainability and effectiveness of structures like Hunters Run Structure R-42 for the benefit of all stakeholders involved.

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.
