Summary

With a dam height of 35.3 feet and a storage capacity of 81 acre-feet, this earthen structure plays a significant role in providing water-based activities for the community. The dam overlooks a tributary to the Hocking River, enhancing the natural beauty of the area and creating a serene environment for visitors to enjoy.

Despite its scenic appeal, Lake Loretta Dam has been rated as having a poor condition assessment, with a significant hazard potential. This assessment was last conducted in 2017, highlighting the need for ongoing maintenance and potential improvements to ensure its safety and longevity. The Department of Natural Resources in Ohio regulates the dam, overseeing its inspection, permitting, and enforcement to mitigate any risks associated with its operation.

As climate change continues to impact water resources and infrastructure, the management of Lake Loretta Dam becomes increasingly crucial. Its role in providing recreational opportunities, water storage, and environmental benefits underscores the importance of proactive maintenance and risk management measures. With a focus on sustainability and safety, efforts to address the dam's condition and potential hazards will be essential in safeguarding this valuable water resource for future generations of enthusiasts.

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.
