Summary
2, located in Fulton County, Ohio, is a crucial water supply resource managed by the local government. Constructed in 1984, this Earth-type dam stands at 42 feet tall and stretches 5728 feet in length, with a storage capacity of 1510.5 acre-feet. The reservoir serves as a primary source for water supply, drawing from the offstream Bad Creek and holding a normal storage volume of 1230 acre-feet over a surface area of 50 acres.
Regulated by the Department of Natural Resources in Ohio, this reservoir has a high hazard potential but is currently assessed as being in satisfactory condition as of the last inspection in September 2017. With a moderate risk rating, the dam operates with uncontrolled spillways and outlet gates, posing challenges for managing water discharge during peak flows. Despite these risks, the reservoir plays a vital role in supporting water supply needs in the region, emphasizing the importance of ongoing monitoring and maintenance to ensure its continued functionality and safety for the surrounding community and ecosystems.

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.
