Summary
Constructed in 1998 by designers Farnsworth & Wylie, this earth-type dam stands at a height of 11 feet and spans a length of 850 feet. With a storage capacity of 150 acre-feet and a normal storage of 80 acre-feet, the dam plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the Illinois Department of Natural Resources, Eagle Creek East Dam is regulated, permitted, inspected, and enforced by the state to ensure its structural integrity and operational effectiveness. With a low hazard potential and a moderate risk assessment rating, the dam provides a necessary safeguard against flooding while also supporting the local ecosystem. With a spillway width of 4 feet and a maximum discharge capacity of 300 cubic feet per second, the dam is equipped to handle excess water flow and prevent overflow.
While the condition assessment of Eagle Creek East Dam is currently not available, regular inspections are conducted to monitor its performance. With a designated emergency action plan and a focus on risk management measures, the dam exemplifies a commitment to public safety and environmental preservation. As a key infrastructure in flood risk reduction efforts, Eagle Creek East Dam stands as a testament to the importance of water resource management in mitigating the impacts of climate change.

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.
