Summary

Constructed in 1909, this earth dam stands at a height of 43 feet and spans 800 feet, creating a storage capacity of 590 acre-feet. With a normal storage capacity of 350 acre-feet and a surface area of 26 acres, Cloe Lake offers a scenic and serene environment for outdoor enthusiasts to enjoy various recreational activities.

The dam's spillway, of the uncontrolled type, adds to the picturesque landscape of the lake, which is fed by Jackson Run. Despite being classified as having a high hazard potential, Cloe Lake currently maintains a satisfactory condition assessment. The last inspection in October 2020 deemed the structure to be in good standing, with a moderate risk assessment rating of 3. As a popular destination for water and climate enthusiasts, Cloe Lake provides a vital recreational outlet for the local community and visitors alike.

In the event of an emergency, the dam at Cloe Lake has a designated emergency action plan (EAP) in place, ensuring that proper guidelines and measures are in effect to address any potential risks. With Glenn Thompson serving as the representative for the area, the lake continues to be a well-maintained and regulated water resource within the Pittsburgh District. As a key element of the region's water infrastructure, Cloe Lake stands as a testament to the importance of sustainable water resource management in preserving the natural beauty and recreational opportunities for future generations to come.

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.
