Summary

The dam serves primarily for recreational purposes, providing a storage capacity of 44.8 acre-feet and a surface area of 4 acres. It is regulated by the Department of Natural Resources in Ohio and undergoes regular inspections, with the last assessment conducted in October 2018, determining its condition as satisfactory.

The dam poses a significant hazard potential due to its location and design, but its condition is currently deemed acceptable. The surrounding area is at risk of inundation in the event of a breach, prompting the need for emergency action plans and risk assessments to mitigate potential dangers. Despite its age, Carol-Jane Lake Dam continues to be a vital structure for water resource management and recreational activities in the region, highlighting the importance of ongoing monitoring and maintenance to ensure its safe operation for the community and environment.

With its picturesque setting and historical significance, Carol-Jane Lake Dam stands as a testament to the engineering achievements of the past. As water resource and climate enthusiasts, we appreciate the role it plays in providing recreational opportunities while recognizing the need for proactive measures to safeguard its integrity and protect the surrounding ecosystem. As we continue to study and advocate for sustainable water management practices, Carol-Jane Lake Dam serves as a reminder of the delicate balance between human development and environmental preservation in our ever-changing world.

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.
