Summary

Built in 1976 by the Central Ohio Coal Company, this earth-type dam stands at a height of 75.6 feet and has a storage capacity of 1490 acre-feet. Its primary purpose is for water supply, serving the surrounding area with a normal storage level of 615.4 acre-feet.

Despite its vital role in water resource management, International Animal Preserve Pond Dam #10 poses a high hazard potential due to its poor condition assessment as of November 2017. The dam has a drainage area of 1.66 square miles and can discharge up to 4565 cubic feet per second. With a surface area of 33.5 acres, the dam is regulated by the Department of Natural Resources in Ohio and undergoes regular inspections and enforcement to ensure public safety.

As an important water infrastructure in Muskingum County, Ohio, this dam requires careful monitoring and potential rehabilitation to mitigate risks and maintain its functionality for water supply purposes. With concerns about its condition and hazard potential, stakeholders and water resource enthusiasts are encouraged to stay informed about the ongoing management and maintenance efforts for International Animal Preserve Pond Dam #10 to ensure the safety and sustainability of this essential water resource feature.

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.
