Summary
Built in 1952 by JAMES MILLER, this earth dam stands at a height of 20 feet and spans 330 feet in length. It holds a maximum storage capacity of 214 acre-feet, with a normal storage level of 171 acre-feet, making it a vital resource for the surrounding area.
The dam is regulated and inspected by the Illinois Department of Natural Resources, ensuring that it meets safety standards and is in good condition. With a low hazard potential and moderate risk assessment, Millers Lake Dam plays a crucial role in managing water resources in the region. Although the dam does not have an Emergency Action Plan in place, its regular inspections and maintenance contribute to its overall safety and functionality.
As a key feature on TRIB BIG CREEK, Millers Lake Dam serves not only as a water management structure but also as a recreational spot for the community. With its uncontrolled spillway and outlet gates, this dam is an important asset for both fire protection and leisure activities in the area. Its historical significance, combined with its practical utility, makes Millers Lake Dam a valuable and intriguing site for water resource and climate enthusiasts to explore.

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.
