Summary
Completed in 1951, this earth dam stands at a height of 30 feet and spans 700 feet across Spring Creek. With a primary purpose of recreation, the dam provides storage capacity of 1,096 acre-feet, with normal storage levels at 379 acre-feet. Despite being state regulated and inspected, the hazard potential of the dam is considered low, with a moderate risk assessment rating.
Managed by the Illinois Department of Natural Resources, Newell Dam serves as a popular recreational spot in the area, offering opportunities for fishing, boating, and other water-based activities. The dam features an uncontrolled spillway with a width of 50 feet and is located in a picturesque setting that attracts visitors looking to enjoy the outdoors. While the dam has not undergone a recent condition assessment, its risk management measures are in place to ensure the safety of the surrounding community.
With its historical significance and strategic location within the Chicago District, Newell Dam plays a crucial role in water resource management and climate adaptation efforts in the region. As an integral part of the local ecosystem, the dam provides not only recreational benefits but also serves as a key infrastructure for flood control and water supply management. Despite its age, Newell Dam continues to be a valuable asset for the community, showcasing the importance of sustainable water resource practices in the face of changing climate conditions.

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.
