Summary
Built in 1916, this earth dam stands at a height of 25.9 feet and has a length of 325 feet. With a storage capacity of 70 acre-feet and a normal storage of 34.3 acre-feet, the dam is situated on a tributary to San Toy Creek, providing a surface area of 5.7 acres for activities such as fishing, boating, and wildlife observation.
Despite its historic significance, San Toy Dam is classified as high hazard potential with a poor condition assessment as of May 2017. The dam is regularly inspected by the Ohio Department of Natural Resources to ensure its safety and compliance with state regulations. As a key recreational asset in Perry County, Ohio, San Toy Dam plays a vital role in water resource management and climate adaptation efforts in the region.
With its picturesque location and significant storage capacity, San Toy Dam stands as a reminder of Ohio's rich water resource heritage. As water resource and climate enthusiasts explore the dam's surroundings, it is crucial to acknowledge the potential hazards associated with its condition and take necessary steps to ensure public safety and environmental sustainability for future generations.

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.
