Summary

2, located in Lancaster, Ohio, is a crucial flood risk reduction infrastructure managed by the local government with oversight from the Department of Natural Resources. Built in 1955 by USDA NRCS, this earth dam stands at a height of 56.4 feet and spans 960 feet, providing storage capacity of 828 acre-feet. With a primary purpose of flood risk reduction, this structure plays a key role in safeguarding the surrounding area from potential flooding events.

This significant dam, associated with the tributary to Hunters Run, has a satisfactory condition assessment and is inspected every five years to ensure its structural integrity. With a moderate risk assessment rating, the dam has a hazard potential that requires attention, although it currently meets guidelines for emergency action plans. The spillway of this uncontrolled structure is designed to handle a maximum discharge of 2566 cubic feet per second, protecting the area from potential inundation during heavy rainfall events. Overall, Hunters Run Structure No. 2 serves as a critical piece of infrastructure in managing water resources and mitigating flood risks in Fairfield County, Ohio.

As water resource and climate enthusiasts, understanding and monitoring the condition of infrastructure like Hunters Run Structure No. 2 is vital for ensuring the safety and resilience of communities in the face of changing weather patterns and increased flood risks. By staying informed about the design, maintenance, and inspection protocols of dams like this one, enthusiasts can contribute to the ongoing efforts to protect water resources and enhance climate resilience in the region. With a focus on sustainable water management practices and proactive risk mitigation strategies, the management of structures like Hunters Run Structure No. 2 can serve as a model for effective flood risk reduction in the face of a changing climate.

Dam Data Reference

Condition Assessment

Satisfactory
No 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

High
Dams 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.
