Summary
Completed in 1941, the dam stands at a height of 34.7 feet and spans 1800 feet in length, creating a reservoir with a storage capacity of 1750 acre-feet. Primarily used for recreation, the dam is situated on Mill Creek and is regulated by the Department of Natural Resources in Ohio.
With a drainage area of 38.3 square miles, Harrison Lake Dam has a significant hazard potential and is rated in poor condition as of the last assessment in May 2018. Despite its condition, the dam continues to serve its purpose of providing recreational opportunities in the area. Its emergency action plan was last revised in March 2019, ensuring that necessary measures are in place in case of a potential emergency situation.
As a crucial water resource in the region, Harrison Lake Dam plays a vital role in water management and recreation for the local community. Enthusiasts interested in water resources and climate will find the history and characteristics of this dam intriguing, as well as the ongoing efforts to maintain its integrity and safety for the surrounding area.

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.
