Summary
2, located in Hancock County, Ohio, is a vital water supply infrastructure designed by Lester H. Poggemeyer, P.E., Inc. The reservoir was completed in 1979 and serves as a critical water resource for the local government in McComb. With a dam height of 32 feet and a storage capacity of 550 acre-feet, the reservoir plays a key role in water management and supply for the region.
Managed by the Department of Natural Resources in Ohio, McComb Upground Reservoir No. 2 is regulated, permitted, and inspected to ensure its safety and functionality. The dam, primarily an earth structure, covers a surface area of 20 acres and has a drainage area of 0.03 square miles. Despite being assessed as having a fair condition, the reservoir poses a high hazard potential, emphasizing the importance of regular inspections and maintenance to mitigate any risks associated with its operation.
With its proximity to Rader Creek and its strategic location in the Buffalo District, McComb Upground Reservoir No. 2 stands as a crucial water supply asset in the region. As a site of water storage and management, the reservoir's significance lies in its contribution to ensuring a reliable water source for the community, highlighting the intersection of water resource management and climate resilience in the context of local infrastructure development.

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.
