Summary
Built in 1957 for recreational purposes, this private Earth dam boasts a height of 25 feet and a length of 309 feet, providing a storage capacity of 52 acre-feet. The dam's primary source agency is the Illinois Department of Natural Resources (IDNR), which oversees its regulation, inspection, and enforcement to ensure its safety and functionality.
Despite its low hazard potential, South Warner Pond Dam is subject to regular inspections every five years to maintain its structural integrity. With an uncontrolled spillway and outlet gates, the dam serves as a vital component in managing water levels in the tributary West Fork Kickapoo Creek. The risk assessment for this dam is moderate, highlighting the importance of ongoing risk management measures to safeguard the surrounding community and environment.
As water resource and climate enthusiasts, it is crucial to recognize the significance of structures like South Warner Pond Dam in promoting sustainable water usage and mitigating the impacts of climate change. By understanding the dam's design, purpose, and risk profile, we can work towards enhancing its resilience and ensuring its continued contribution to water management efforts in Illinois.

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.
