Summary

Built in 1955, this earth dam stands at a height of 15 feet and stretches 212 feet in length. With a primary purpose of recreation, the dam creates a storage capacity of 72 acre-feet, providing ample water for various outdoor activities.

Despite its low hazard potential, the dam is subject to regular inspections, with the last one conducted in April 2019. The spillway, measuring 18 feet wide, is uncontrolled, adding to the natural beauty and serenity of the surrounding area. Additionally, the dam's risk assessment has been classified as moderate (3), indicating a need for ongoing monitoring and management to ensure the safety and integrity of the structure.

Water resource and climate enthusiasts will appreciate the unique features of New West Fork Club Lake Dam, such as its buttress core type and unlisted foundation. As a vital element in the local ecosystem, the dam offers opportunities for recreational enjoyment while also serving as a reminder of the importance of responsible water management practices. With its scenic location along the Tributary West Fork Richland Creek, this dam represents a harmonious blend of human intervention and natural beauty in Illinois' St. Clair County.

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.
