Summary
4, located in Huron County, Ohio, is a vital water supply resource designed by William G. Clark and completed in 1919. This Earth dam stands at a height of 18 feet and has a storage capacity of 544 acre-feet, serving the city of Bellevue and surrounding areas. With a surface area of 32.4 acres and a drainage area of 0.05 square miles, this reservoir plays a crucial role in water management and supply for the region.
Despite its historical significance, Bellevue Upground Reservoir No. 4 currently faces challenges in terms of its condition assessment, which is rated as poor with a high hazard potential. The last inspection in June 2018 highlighted the need for improvements and maintenance to ensure the safety and efficiency of the dam. The Department of Natural Resources in Ohio regulates this reservoir, highlighting the importance of state oversight and enforcement in maintaining the integrity of water infrastructure in the region.
Given its critical role in water supply, it is essential for authorities and stakeholders to address the maintenance and condition assessment issues facing Bellevue Upground Reservoir No. 4. With a focus on risk management measures and improvements to its emergency action plan, this reservoir can continue to provide a reliable water source for the community while ensuring the safety and security of its infrastructure in the face of changing climate 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.
