Summary
1, located in Hancock County, Ohio, is a vital water resource managed by the local government for water supply purposes. Constructed in 1950, this earth dam stands at a height of 27.7 feet and has a storage capacity of 4,969 acre-feet, with a normal storage of 4,008 acre-feet. Situated on the Blanchard River offstream, this reservoir covers an area of 188 acres and serves as a crucial component of the local water infrastructure.
Managed by the Department of Natural Resources in Ohio, Findlay Upground Reservoir No. 1 undergoes regular inspections with a high hazard potential and fair condition assessment. With a history of construction by JONES AND HENRY, LTD. from Toledo, Ohio, this reservoir plays a significant role in water management and conservation efforts in the region. The reservoir's location, close to Findlay City, ensures a reliable water supply for the surrounding communities, contributing to sustainable water resource management in the area.
Despite its age, Findlay Upground Reservoir No. 1 continues to meet regulatory standards, demonstrating its importance as a key water supply infrastructure in the region. With a focus on water supply and safety, this reservoir plays a crucial role in ensuring water availability for the local population and serves as a critical asset for managing water resources in Hancock County, Ohio. As climate change impacts water availability, the proper maintenance and management of reservoirs like this become increasingly essential for ensuring a sustainable water supply in the face of changing 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.
