Summary
Completed in 1940, this earth dam spans 390 feet and sits on Neffs Run, providing essential water resources for the region. However, with a high hazard potential and poor condition assessment, the dam's safety and maintenance are of utmost importance.
Managed by the Department of Natural Resources in Ohio, the dam's last inspection in 2017 revealed its poor condition, prompting a need for regular monitoring and upgrades. Despite its critical role in water supply, its high hazard potential underscores the importance of addressing any structural deficiencies to ensure the safety of nearby communities and the environment. With a risk assessment and management measures yet to be fully implemented, the dam's future maintenance and safety remain priorities for water resource and climate enthusiasts in the area.
As the community relies on Belmont Hills Country Club Lake Dam for water supply, its structural integrity and maintenance are key concerns for local authorities. With a designated emergency action plan yet to be prepared or reviewed, there is a pressing need to ensure that the dam meets safety guidelines and is adequately monitored for any potential risks. As climate change impacts intensify, the resilience and safety of this vital water infrastructure must be prioritized to safeguard the surrounding area from potential hazards and ensure a sustainable water supply for the future.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
