Muskingum River Upper Fly Ash Dam Reservoir Report
Last Updated: February 21, 2026
The Muskingum River Upper Fly Ash Dam is a critical earth dam located in Beverly, Ohio, designed by HARZA ENGINEERING CO.
Summary
The dam was completed in 1975 and stands at a height of 152 feet, with a length of 6909 feet, serving primarily as a tailings structure. It is regulated by the Ohio Department of Natural Resources and has a storage capacity of 6900 acre-feet, making it an important water resource in the region.
With a high hazard potential and fair condition assessment, the Muskingum River Upper Fly Ash Dam requires frequent inspections every five years to ensure its structural integrity. The dam is situated on a tributary to the Muskingum River and plays a crucial role in water management for the area. Its location in Washington County, Ohio, underscores its importance in protecting the surrounding communities from potential flooding and ensuring a stable water supply.
As a public utility-owned structure, the Muskingum River Upper Fly Ash Dam represents a key piece of infrastructure for water resource and climate enthusiasts. Its strategic design and maintenance are essential in safeguarding the local ecosystem and supporting sustainable water management practices.

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.
