Summary

With a height of 66.9 feet and a length of 490 feet, the dam serves primarily for recreational purposes, providing storage of 2,665 acre-feet of water and covering a surface area of 82 acres. Its normal storage capacity is 1,539 acre-feet, supporting activities such as fishing, boating, and swimming in the surrounding area.

This dam, regulated by the Ohio Department of Natural Resources, poses a high hazard potential but is currently assessed as fair in condition. Inspected every 5 years, the last assessment in May 2018 found the structure to be in adequate shape. Despite its age, Mineral Springs Resort Lake Dam continues to offer a vital resource for the community, managing water flow into the tributary of Cedar Fork and ensuring the safety of the surrounding area from potential flooding events.

As a key feature in the region, Mineral Springs Resort Lake Dam stands as a testament to engineering excellence and responsible water management. With its strategic location and significant storage capacity, the dam plays a crucial role in supporting recreational activities while also safeguarding the local ecosystem. As water resource and climate enthusiasts, understanding the importance of structures like this and their impact on the environment is essential for promoting sustainable practices and preserving our natural resources for future generations.

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.
