Summary
Built in 1967, this earth dam stands at a height of 30 feet and has a length of 380 feet, with a storage capacity of 183 acre-feet. Situated on the TRIB CAHOKIA CREEK, the dam is regulated by the Illinois Department of Natural Resources, ensuring that it meets inspection and enforcement requirements.
With a spillway width of 33 feet and uncontrolled spillway and outlet gates, Lake Meadow Dam has a low hazard potential and a moderate risk assessment rating. While its condition assessment is currently unavailable, the dam undergoes inspections every five years to ensure safety and compliance. Despite its limited federal agency involvement, the dam is maintained by private owners and remains a vital component of the local water resource infrastructure in Edwardsville, Illinois.
For water resource and climate enthusiasts, Lake Meadow Dam offers a glimpse into the importance of private infrastructure in managing water resources for recreational purposes. Its location on the TRIB CAHOKIA CREEK, controlled by the Illinois Department of Natural Resources, showcases the collaboration between private owners and state regulatory agencies in ensuring the safety and functionality of such structures. As a low-hazard dam with a moderate risk assessment, Lake Meadow Dam serves as a reminder of the ongoing maintenance and inspection efforts required to mitigate potential risks and uphold water resource management standards in the region.

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.
