Summary
Completed in 2003, this earth dam stands at a height of 17 feet and spans a length of 14,500 feet, with a storage capacity of 3,945 acre-feet. The dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its structural integrity and safety.
With a controlled spillway and a low hazard potential, the Newton Power Station Supplemental Cooling Pond Dam plays a crucial role in managing water resources and mitigating potential risks associated with its operation. The dam's proximity to the Trib Newton Lake ensures a reliable source of water for cooling purposes, while also serving as a protective barrier against potential flooding events. Despite its low hazard potential, the dam is subject to a very high risk assessment due to its critical function in supporting the power station's operations.
Managed by a public utility and designed by Sargent & Lundy, the Newton Power Station Supplemental Cooling Pond Dam represents a collaborative effort to uphold water resource sustainability and climate resilience in the region. As a key infrastructure component in the area's water management system, this dam stands as a testament to the intersection of engineering innovation and environmental stewardship in ensuring the efficient and safe operation of power generation facilities.

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.
