Summary
Built in 1891, this concrete dam stands at a height of 20 feet and has a hydraulic height of 12.3 feet, serving primarily for recreational purposes. The dam has a storage capacity of 3,761 acre-feet and covers a surface area of 476 acres, with a drainage area of 7,447 acres.
Managed by a private owner, the Stockport Mill Country Inn Water Power Project is regulated by the Ohio Department of Natural Resources and the Federal Energy Regulatory Commission. With a high hazard potential, the dam has a moderate risk assessment rating. Despite its age, the dam has not had a recent condition assessment and its emergency action plan has not been updated in several years, suggesting potential vulnerabilities that should be addressed.
Located on the Muskingum River and part of the Huntington District, the Stockport Mill Country Inn Water Power Project serves as a picturesque attraction for water resource and climate enthusiasts. With its rich history and unique water power capabilities, this site offers a glimpse into the past while also highlighting the importance of sustainable water management practices in the present day.

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.
