Summary

Designed by HOELSCHER ENGINEERING, this earth dam stands at a height of 68 feet and spans 400 feet in length. With a maximum storage capacity of 40 acre-feet and a normal storage of 10 acre-feet, this dam plays a crucial role in managing water resources in the area.

Managed by the local government, the Village of Valmeyer Dam is regulated by the Illinois Department of Natural Resources (IDNR) and undergoes regular inspections to ensure its structural integrity. Despite its low hazard potential, the dam poses a moderate risk (rated 3) and has an emergency action plan in place. With its uncontrolled spillway and outlet gates, the dam serves as a key infrastructure for mitigating flood risks and protecting the surrounding community from potential water-related disasters.

For water resource and climate enthusiasts, the Village of Valmeyer Dam presents an intriguing case study in flood risk reduction and water management. As a vital piece of infrastructure in Illinois, this earth dam stands as a testament to engineering excellence and plays a crucial role in safeguarding the local area from the impacts of extreme weather events. With its strategic location and design features, the dam serves as a beacon of resilience against the challenges posed by climate change and fluctuating water levels in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
