Summary
This Earth dam type, with a height of 21 feet and a length of 1136 feet, is situated on the TRIB DE ARCY BRANCH river or stream. Managed by a private owner, the dam is regulated by the Illinois Department of Natural Resources (IDNR) and undergoes regular inspections to ensure its safety and compliance with state regulations.
With a maximum storage capacity of 72 acre-feet and a normal storage capacity of 38 acre-feet, West Lake Country Club Lake Dam has a low hazard potential and a moderate risk assessment rating. The dam features an uncontrolled spillway, with a width of 52 feet, and is equipped with uncontrolled outlet gates. Despite its age, the condition assessment of the dam is currently not available, and there is no Emergency Action Plan (EAP) in place.
Although the risk associated with West Lake Country Club Lake Dam is considered moderate, its purpose in providing recreational opportunities to the local community remains a key aspect of its existence. Regular inspections and adherence to state regulations ensure the safety and functionality of the dam, serving as a vital component of the surrounding environment and water resource management in the area.

Dam Data Reference
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.
