Summary
Built in 1965 by FREEMAN UNITED COAL CO., this earth dam stands at 37 feet high and spans 469 feet in length, creating a reservoir with a storage capacity of 520 acre-feet. The dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its safety and compliance with state regulations.
With a low hazard potential and a moderate risk assessment rating, the Msdgc Road Fill Lake Dam is a relatively stable structure that contributes to the local community's recreational opportunities. Despite its uncontrolled spillway type and outlet gates, the dam has not experienced any significant issues as of the last inspection in November 2017. While the condition assessment is currently unavailable, the dam continues to serve its intended purpose of providing a scenic and enjoyable environment for residents and visitors alike to appreciate and engage with the natural surroundings.
As a key feature in the TRIB SLUG RUN CREEK watershed, the Msdgc Road Fill Lake Dam plays a role in water resource management and environmental stewardship in Fulton County, Illinois. Its presence adds to the overall landscape and contributes to the sustainable use of water resources for recreational and community benefit. With ongoing monitoring and maintenance, this dam remains a valuable asset for both local residents and those interested in the intersection of water resources and climate dynamics.

Dam Data Reference
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.
