Summary
ANDERSON & ASSOCIATES. Completed in 1998, this earth dam stands at a height of 26 feet and spans a length of 3600 feet, creating a reservoir with a storage capacity of 155 acre-feet. Situated on the offstream of Mill Creek, this dam serves various purposes such as water storage and flood control, with a low hazard potential and high risk assessment rating.
Managed by the Illinois Department of Natural Resources, the Fox Mill Lagoon 1 Dam undergoes regular state inspections and enforcement to ensure its structural integrity and compliance with regulations. With a normal storage volume of 100 acre-feet and a surface area of 7 acres, this dam plays a crucial role in water resource management in the region. Although it does not have a spillway, the dam's risk management measures are in place to mitigate any potential hazards.
Even though the condition assessment of the Fox Mill Lagoon 1 Dam is currently not available, the emergency action plan and risk assessment indicate a proactive approach to dam safety. With no federal agency involvement, this local dam exemplifies the importance of state-regulated structures in safeguarding water resources and adapting to the challenges posed by climate change. For water resource and climate enthusiasts, the Fox Mill Lagoon 1 Dam serves as a fascinating example of local infrastructure supporting community resilience and environmental sustainability.

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.
