Nearby: Lake Christine Dam Inez Lake Dam
Last Updated: February 6, 2026
Chenot Lake Dam, also known as Miller Lake, is a privately-owned structure located in Belleville, Illinois.
Summary
Built in 1960, this earth dam stands at a height of 15 feet and spans 150 feet in length, serving primarily for recreational purposes. Situated along the Trib Loop Creek, the dam offers a serene escape for water resource and climate enthusiasts seeking outdoor activities in St. Clair County.
With a storage capacity of 12 acre-feet, Chenot Lake Dam has a spillway type categorized as "Uncontrolled" and a high hazard potential. Despite its age, the dam is inspected annually to ensure public safety, with the last inspection conducted in September 2020. While the condition assessment is not available, the risk assessment indicates a moderate risk level (3), prompting the need for effective risk management measures to safeguard the surrounding community.
As a key feature in the local landscape, Chenot Lake Dam serves as a reminder of the importance of proper dam management and maintenance in mitigating potential risks and ensuring the sustainable use of water resources. Its presence offers a recreational haven for visitors while highlighting the need for ongoing vigilance in monitoring and addressing any safety concerns related to dam infrastructure.

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.
