Summary
1, located in Burtonville, Ohio, is a vital water supply source for the local community. Constructed in 1945, this Earth-type dam stands at a height of 18.6 feet and has a storage capacity of 371 acre-feet, with a normal storage level of 307 acre-feet. The reservoir covers an area of 15.6 acres and serves the primary purpose of water supply.
Managed by the local government, this reservoir is regulated and inspected by the Department of Natural Resources in Ohio. Despite being classified as having a high hazard potential, the dam is currently in fair condition as of the last assessment in May 2019. With an inspection frequency of every 5 years, the dam is closely monitored to ensure its safety and integrity in providing reliable water resources to the surrounding area.
Wilmington Upground Reservoir No. 1 plays a crucial role in water resource management in Clinton County, Ohio, serving as a key infrastructure for water supply. With its historical significance dating back to the mid-20th century, the dam continues to be a critical component of the region's water infrastructure, highlighting the importance of ongoing maintenance and monitoring to ensure its continued functionality and safety for the community.

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.
