Summary
This earth dam, designed by AEP with Casagrande and completed in 1968, serves the primary purpose of containing tailings. With a height of 100 feet and a length of 950 feet, the dam has a storage capacity of 739 acre-feet and a normal storage level of 445 acre-feet. It is regulated by the Department of Natural Resources and undergoes regular inspections to ensure its structural integrity.
The dam poses a high hazard potential and is considered to be in satisfactory condition as of the last assessment in November 2018. It has a drainage area of 0.18 square miles and can discharge a maximum of 552 cubic feet per second. The Muskingum River Middle Fly Ash Dam plays a crucial role in managing water resources in the area, protecting against potential flooding and ensuring the safety of downstream communities. Enthusiasts of water resources and climate will find this structure to be an important component of the region's infrastructure, highlighting the intersection of human engineering with natural systems.

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.
