Summary
Designed by HURST-ROSCHE ENGINEERS and completed in 1989, this earth dam stands at 29 feet tall and stretches 910 feet in length, with a storage capacity of 9,450 acre-feet. Situated on the Embarras River, the dam serves the primary purpose of water supply for the surrounding area, with a normal storage capacity of 750 acre-feet and a maximum discharge rate of 52,307 cubic feet per second.
With a significant hazard potential and a moderate risk rating, Riverview Dam is regulated by the Illinois Department of Natural Resources (IDNR) and undergoes regular state inspections, permitting, and enforcement. The dam features an uncontrolled spillway type with a width of 432 feet, and its condition assessment is currently not available. While the dam has not experienced any structural modifications in recent years, it remains a key component of the region's water resource infrastructure, ensuring reliable water supply and flood control along the Embarras River.
Water resource and climate enthusiasts can appreciate Riverview Dam for its essential role in water supply management in Coles County, Illinois. As a vital piece of infrastructure, this earth dam provides critical storage capacity and flood protection for the surrounding area, highlighting the importance of sustainable water resource management in the face of changing climate conditions. With its regulated operations and state oversight, Riverview Dam exemplifies the collaborative efforts required to maintain safe and efficient water supply systems in communities across Illinois.

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.
