Summary

With a dam height of 13.6 feet and a storage capacity of 46 acre-feet, this earthen dam plays a crucial role in managing water resources in the area. The dam's primary purpose is for recreation, offering a surface area of 4 acres for various outdoor activities.

Despite its significant hazard potential and poor condition assessment as of 2017, Mcclintock Lake Dam remains a key feature in the local landscape, providing both recreational opportunities and water management benefits. The dam is inspected every five years to ensure its structural integrity and safety, with the Department of Natural Resources overseeing its regulation, permitting, and enforcement. As a tributary to the Ottawa River, the dam contributes to the overall ecosystem health and water flow management in the region.

Water resource and climate enthusiasts will find Mcclintock Lake Dam to be a fascinating structure that showcases the intersection of human engineering with natural elements. Its presence not only enhances recreational opportunities in the area but also plays a vital role in water storage and management. With ongoing inspections and regulatory oversight, this dam continues to serve as a valuable asset in maintaining the balance of water resources and environmental sustainability in Allen County, Ohio.

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.
