Newton Station Ash Pond Reservoir Report
Last Updated: March 18, 2026
Newton Station Ash Pond, located in Jasper County, Illinois, is a state-regulated water resource managed by a public utility.
Summary
This rockfill dam, standing at a height of 22 feet with a length of 2400 feet, serves as a critical structure along the Newton Lake tributary. Despite the dam's spillway being uncontrolled, it poses a significant hazard potential, leading to a moderate risk assessment.
Although the condition assessment of Newton Station Ash Pond is currently not available, the dam undergoes inspections every three years to ensure its structural integrity. The Emergency Action Plan (EAP) for the site was last revised in April 2017, indicating a commitment to emergency preparedness. With the dam being categorized as a moderate risk, it is crucial for water resource and climate enthusiasts to monitor any potential changes or updates regarding its management and maintenance.

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.
