Summary
Completed in 2003, this earth dam stands at a height of 47 feet and spans 450 feet in length, serving primarily for recreational purposes. With a storage capacity of 191.9 acre-feet and a drainage area of 0.29 square miles, the dam holds a significant amount of water from the tributary to Seneca Fork Willis Creek, providing a picturesque surface area of 8.3 acres for water enthusiasts to enjoy.
Maintained and regulated by the Ohio Department of Natural Resources, Cline Lake Dam has a hazard potential classified as high, yet its condition is assessed as fair as of the last inspection in November 2017. Despite its potential risks, the dam has been deemed safe for recreation, with a maximum discharge capacity of 3,468 cubic feet per second. The Emergency Action Plan (EAP) for the dam was last revised in June 2017, ensuring that necessary protocols are in place in case of emergencies, although details of its adherence to guidelines and risk management measures are not specified in the data.
For water resource and climate enthusiasts, Cline Lake Dam offers a fascinating insight into the intricate balance between human infrastructure and natural water systems. Its construction and management reflect the importance of responsible stewardship of our water resources, especially in the face of climate change challenges. As a recreational haven nestled in the heart of Ohio, Cline Lake Dam stands as a testament to the harmonious coexistence of man-made structures and ecological landscapes, inviting visitors to appreciate the beauty and functionality of this vital water resource in the region.

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.
