Summary

Built in 1950, this earth dam stands at a height of 32.5 feet and has a storage capacity of 83.2 acre-feet. With a normal storage capacity of 54.4 acre-feet and a surface area of 6.5 acres, this dam serves as a recreational hub for the local community.

Managed by the Department of Natural Resources in Ohio, the Allegheny West Conference Cg Lake Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. Despite its low hazard potential, the dam is classified as satisfactory in condition and undergoes inspections every five years to maintain its structural integrity. The dam's emergency action plan is up to date, with the last revision in August 2018, indicating a proactive approach to safety and risk management.

Situated near the tributary to Little Rush Creek, the Allegheny West Conference Cg Lake Dam provides a serene environment for water resource and climate enthusiasts to enjoy recreational activities. With its picturesque surroundings and well-maintained structure, this dam stands as a testament to responsible dam management and the harmonious coexistence of human activities with natural resources.

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.
