Summary
Built in 1976 by INLAND STEEL, this dam serves as a vital water supply structure in the area, with a maximum storage capacity of 215 acre-feet and a normal storage level of 120 acre-feet. The dam stands at a height of 15 feet and stretches 2400 feet in length, with a controlled spillway width of 157 feet.
Managed by the Illinois Department of Natural Resources, Arentsen Pond 2 Dam is regulated, inspected, and enforced to ensure its structural integrity and safety. Its hazard potential is classified as low, but its risk assessment is considered very high, emphasizing the importance of proper risk management measures. Although the condition assessment of the dam is currently not available, regular inspections are conducted every five years to monitor its performance and address any potential issues that may arise.
Situated along the tributary of Wheeler Creek, Arentsen Pond 2 Dam plays a crucial role in water resource management in Hamilton County, Illinois. With its primary purpose being water supply, this dam serves as a key infrastructure for the local community, highlighting the intersection of water resource management and climate resilience in the region.

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.
