Summary

Completed in 1954, this earth dam stands at a height of 29 feet and spans a length of 490 feet. With a storage capacity of 224 acre-feet, the dam sits on the tributary of Douglas Creek, offering a serene setting for water and climate enthusiasts alike.

Managed by the Illinois Department of Natural Resources, the Beil Lake 2 Dam has a low hazard potential and is inspected every five years to ensure its safety and integrity. Despite its uncontrolled spillway and outlet gates, the dam poses a moderate risk level of 3. The structure is situated within the St. Louis District of the US Army Corps of Engineers and has Congressman Mike Bost representing the area.

Although the condition assessment and emergency action plan details are not available, the Beil Lake 2 Dam continues to serve as a recreational haven in St. Clair County, Illinois. With its picturesque location and moderate risk level, this earth dam offers a balance of leisure and safety for visitors to enjoy the beauty of nature in a controlled environment.

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.
