Summary
As a local government-owned dam with a height of 11 feet and a length of 1000 feet, it plays a crucial role in protecting the surrounding areas from potential flooding events. With a storage capacity of 79 acre-feet and a maximum discharge of 928 cubic feet per second, this earth dam serves its primary purpose effectively.
Located in McLean County, Illinois, Eagle Creek Dam is regulated by the Illinois Department of Natural Resources (IDNR) and undergoes regular inspections to ensure its structural integrity. With a hazard potential rated as low and a moderate risk assessment, the dam is equipped with uncontrolled spillways and outlet gates to manage water levels during high flow periods. Despite its low hazard potential, the dam presents a moderate risk level, indicating the need for continued monitoring and risk management measures to maintain its functionality and safety standards.
Eagle Creek Dam stands as a testament to effective flood risk reduction efforts in the region, providing essential protection to the community along Sugar Creek. With a focus on safety and risk management, this dam serves as a critical infrastructure piece in safeguarding the surrounding areas from potential flooding incidents. Its design and construction showcase a commitment to water resource management and climate resilience, ensuring the continued protection of the local population and environment.

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.
