Summary

With a primary purpose of recreation, this earth dam stands at a structural height of 21 feet and a hydraulic height of 19.5 feet. The dam has a storage capacity of 16 acre-feet and a length of 312 feet, making it a significant contributor to water resource management in the area.

Despite not being state-regulated, Cloer Dam is inspected regularly and was last assessed in November 2019, with a fair condition rating. The dam poses a significant hazard potential, indicating the importance of ongoing maintenance and risk management measures. While the dam does not have an Emergency Action Plan in place, its strategic location and storage capacity make it a crucial asset for both water supply and recreational activities in Union County.

As a key feature in the Charleston District, Cloer Dam serves as a vital resource for the local community and visitors alike. With its picturesque surroundings and recreational opportunities, this dam stands as a testament to the intersection of water resource management and environmental stewardship 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.
