Summary
The dam, standing at 25 feet high and stretching 9600 feet in length, plays a crucial role in providing water to the community, with a storage capacity of 2081 acre-feet. Situated near the Sandusky River tributary, this reservoir covers 120 acres and serves as a vital resource for the region.
With the Ohio Department of Natural Resources overseeing regulation, inspection, and enforcement, Upper Sandusky Reservoir #2 maintains a satisfactory condition and has a significant hazard potential. The dam has a designated inspection frequency of 5 years, with the last assessment conducted in June 2018. Despite its age, the reservoir continues to meet water supply demands and contributes to the overall water management infrastructure in the area.
In the event of an emergency, the reservoir's emergency action plan status and risk assessment measures are unclear, highlighting the need for continued monitoring and preparedness. As water resource and climate enthusiasts, understanding the importance of maintaining and safeguarding such critical infrastructure is essential to ensuring a sustainable and resilient water supply for the community. Upper Sandusky Reservoir #2 stands as a testament to the vital role that water resources play in supporting local ecosystems and communities in Ohio.

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.
