Summary
With a height of 25 feet and a length of 650 feet, the dam holds a storage capacity of 125 acre-feet, providing a picturesque setting for water enthusiasts and climate advocates alike. Situated on the TRIB LITTLE FOX RIVER, the dam is regulated by the IDNR and undergoes regular inspections and enforcement to ensure its structural integrity and safety.
Despite its significant hazard potential, the dam boasts a moderate risk assessment and is equipped with an uncontrolled spillway type and outlet gates. The dam's condition assessment is currently not available, but it is subject to a regular inspection frequency of 3. While the Emergency Action Plan status and risk management measures are not specified, the dam's location and design make it a crucial piece of infrastructure for water resource management in Richland County, Illinois, under the oversight of the Louisville District.
Enthusiasts of water resources and climate change advocacy will find Jordan Lake Dam to be a vital recreational asset in Illinois, providing not only a scenic spot for outdoor activities but also serving as a key structure for water storage and management. With its historical significance dating back to the mid-20th century, the dam's ongoing regulatory oversight and risk assessment highlight its importance in ensuring the safety and sustainability of water resources in the region.

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.
