Summary
2 is a key water resource managed by the local government with a high hazard potential. Built in 1963, this Earth-type dam stands at 31 feet tall and spans 6200 feet, providing a maximum storage capacity of 1382 acre-feet and a normal storage of 1074 acre-feet. With a surface area of 55.6 acres and serving as an offstream reservoir, it plays a crucial role in water supply for the region.
The dam is regulated and inspected by the Department of Natural Resources in Ohio, ensuring its safety and compliance with state regulations. While the condition assessment as of May 2019 deemed it satisfactory, its high hazard potential underscores the importance of proper maintenance and monitoring. The Emergency Action Plan (EAP) status and risk assessment for the reservoir are currently unclear, highlighting the need for continued vigilance and preparedness in the face of potential climate-related challenges.
In the event of emergencies, it is essential for stakeholders and the local community to have up-to-date information and contacts for effective response. With the potential impacts of climate change on water resources becoming more pronounced, the management and maintenance of structures like Wilmington Upground Reservoir No. 2 are crucial for ensuring water security and resilience in the face of evolving environmental conditions.

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.
