Summary

With a height of 29 feet and a length of 300 feet, this dam provides a maximum storage capacity of 69 acre-feet and a normal storage of 53 acre-feet. The dam, situated on the TRIB JUDYS BRANCH river stream, is state-regulated by the Illinois Department of Natural Resources (IDNR) and undergoes regular inspections to ensure its safety and functionality.

Despite being classified as having a low hazard potential, the risk assessment for Lakewood Subdivision Lake 2 Dam indicates a moderate risk level (3). While the condition assessment is not available, the dam meets state regulatory requirements and is equipped with uncontrolled spillways and outlet gates. In the event of an emergency, detailed emergency action plans (EAP) are not currently prepared or updated. However, the dam remains a popular recreational spot for water resource and climate enthusiasts, offering a serene environment for outdoor activities and leisure.

Overall, Lakewood Subdivision Lake 2 Dam serves as a significant water resource infrastructure in Madison County, Illinois, providing both recreational opportunities and essential flood control measures. As a private dam under state jurisdiction, it plays a crucial role in managing water levels and protecting the surrounding areas from potential risks. Despite moderate risk assessments, continued monitoring and maintenance ensure the safety and functionality of this important structure for the local community and beyond.

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.
