Summary
2, located in Mt. Orab, Ohio, is a vital water resource infrastructure owned by the local government. Built in 1974, this Earth dam stands at a height of 30.5 feet and has a storage capacity of 454 acre-feet, serving primarily as a water supply source for the region. The reservoir covers a surface area of 22.2 acres and is fed by Sterling Run- Offstream, with a drainage area of 0.04 square miles.
Managed by the Department of Natural Resources in Ohio, this reservoir plays a crucial role in ensuring water security for the area. Despite its high hazard potential, the dam has been assessed as satisfactory in condition as of June 2018, with regular inspections conducted every five years. The Emergency Action Plan for the dam was last revised in October 2020, emphasizing the importance of preparedness and risk management measures for any potential emergencies.
With a history of serving the community for decades, Mount Orab Upground Reservoir No. 2 stands as a testament to the importance of water resource management and infrastructure maintenance in the face of changing climate patterns. As climate enthusiasts and water resource advocates, it is essential to recognize the significance of such structures in ensuring water sustainability and resilience in the region.

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.
