Summary

2 Dam in Clermont, Ohio is a private earth dam completed in 1966 primarily used for water supply purposes. This significant dam stands at a height of 38.5 feet and spans 400 feet in length, with a storage capacity of 120 acre-feet and a drainage area of 0.13 square miles. Situated near the tributary to Ninemile Creek, this dam is regulated by the Ohio Department of Natural Resources and undergoes regular inspections to ensure its structural integrity.

Despite its critical role in providing water supply, the dam's condition was assessed as unsatisfactory during its last inspection in 2018, posing a significant hazard potential. With a maximum discharge capacity of 26 cubic feet per second, it is crucial for the dam to meet safety guidelines and have an effective emergency action plan in place. The dam's Emergency Action Plan (EAP) was last revised in 2017, highlighting the importance of proactive risk management measures to mitigate potential hazards and ensure the safety of surrounding communities.

Given its strategic location and the potential risks associated with its condition, the Royal Oak Golf Course Pond No. 2 Dam serves as a focal point for water resource and climate enthusiasts. As efforts continue to address its unsatisfactory condition and enhance its safety measures, this dam underscores the critical role of infrastructure maintenance and risk assessment in preserving water resources and mitigating climate-related challenges in the region.

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.
