Summary
Completed in 1954, this earth dam stands at a height of 43 feet and spans 1100 feet, holding a maximum storage capacity of 9465 acre-feet. Situated on the Clear Fork river, the dam's hazard potential is classified as high, with a fair condition assessment as of March 2017.
The dam's location in Hocking County, Ohio, near the city of West Logan, offers a surface area of 340 acres and a drainage area of 14.7 square miles. With a normal storage capacity of 3000 acre-feet, Lake Logan Dam plays a crucial role in managing water resources for recreational purposes in the region. Despite its high hazard potential, the dam undergoes regular state inspections, permitting, and enforcement to ensure its structural integrity and safety.
For water resource and climate enthusiasts, Lake Logan Dam serves as a significant landmark in Ohio's water management infrastructure, providing both recreational opportunities and critical storage capacity. With its strategic location and design features, the dam contributes to the overall watershed management of the Clear Fork river, highlighting the importance of sustainable dam operations and maintenance practices in the face of changing climate conditions.

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.
