Summary
This Earth dam stands at a height of 75 feet and spans a length of 1600 feet, with a storage capacity of 660 acre-feet. The primary purpose of this dam is to contain tailings, serving as a vital structure for managing water resources in the region.
Managed by the Department of Natural Resources in Ohio, the Muskingum River Lower Fly Ash Dam is regulated and inspected by the state, ensuring its safety and compliance with guidelines. Despite being classified as having a high hazard potential, the dam's condition is assessed as fair, with the last inspection conducted in November 2018. Emergency action plans are in place, although their last revision was in October 2020, indicating ongoing preparedness efforts.
For water resource and climate enthusiasts, the Muskingum River Lower Fly Ash Dam presents a fascinating case study in dam infrastructure and management. With its critical role in controlling water flow and storage in the tributary to the Muskingum River, this dam exemplifies the importance of responsible design, monitoring, and regulation to ensure both water resource sustainability and public safety in the face of potential hazards.

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.
