Summary
Built in 1968 by the USDA NRCS, this Earth-type dam stands at a height of 26 feet and spans 260 feet in length, with a storage capacity of 55 acre-feet. The dam sits on the TR- WHETSTONE S river or stream, within the jurisdiction of the Illinois Department of Natural Resources.
Despite its low hazard potential, Hayes Pond Dam is subject to state regulation, inspection, and enforcement, ensuring its safety and compliance with standards. With a drainage area of 0.16 square miles and a normal storage capacity of 30 acre-feet, the dam plays a vital role in managing water resources in the region. Its uncontrolled spillway and outlet gates further contribute to the efficient flow and control of water.
For water resource and climate enthusiasts, Hayes Pond Dam offers a fascinating example of how infrastructure can support wildlife conservation and habitat enhancement. Its moderate risk assessment underscores the importance of ongoing monitoring and maintenance to ensure the dam's continued functionality and safety for both the environment and surrounding communities.

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.
