Summary

This dam, completed in 1965, serves as a water supply source with a storage capacity of 391.6 acre-feet and a normal storage level of 94.5 acre-feet. The dam stands at a height of 37.6 feet and stretches 600 feet in length, creating a surface area of 13.7 acres.

Despite its vital role in water supply, the dam has been assessed as being in poor condition during its last inspection in November 2017, with a low hazard potential. The state of Ohio regulates this structure, with the Department of Natural Resources overseeing permitting, inspections, and enforcement. The dam's primary purpose is water supply, serving as a crucial resource for the International Animal Preserve and surrounding areas.

Enthusiasts of water resources and climate will be intrigued by the significance of International Animal Preserve Pond Dam #11 in sustaining the ecosystem and wildlife within the preserve. With ongoing maintenance and monitoring, this dam continues to play a crucial role in water management and conservation efforts in the region, ensuring a sustainable water supply for both human and animal inhabitants.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
