Summary

Situated in the picturesque city of Sugar Bush Knolls, this earth dam stands at a height of 18.3 meters and stretches 400 meters in length, creating a reservoir with a normal storage capacity of 38 million gallons. The dam, regulated by the Department of Natural Resources in Ohio, also serves as a significant hazard potential with a fair condition assessment.

With its location near a tributary to the Cuyahoga River, Lake Quincy Dam provides a serene setting for water resource and climate enthusiasts to explore. The dam's last inspection in April 2017 revealed a fair condition, and it is subject to regular inspections every five years. Despite its significant hazard potential, the dam has a storage capacity of 59 million gallons and covers a surface area of 5.5 acres, making it an essential recreational site in the region.

As a vital recreational resource in Ohio, Lake Quincy Dam offers visitors a chance to appreciate both the beauty of nature and the importance of dam infrastructure. Managed by private owners, this dam continues to play a crucial role in providing recreational opportunities while maintaining a balance between safety and environmental conservation. For water resource and climate enthusiasts, Lake Quincy Dam is a captivating site that showcases the intersection of human ingenuity and natural beauty in a unique and engaging way.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
