Summary
This private dam stands at a height of 37 feet and spans 302 feet in length, with a storage capacity of 123 acre-feet. Despite its relatively low hazard potential and moderate risk assessment rating, the dam is state-regulated and regularly inspected by the Illinois Department of Natural Resources to ensure its safety and compliance with regulations.
The dam features an uncontrolled spillway with a width of 60 feet and outlet gates that are similarly uncontrolled. While the condition assessment of Wilkinson Pond Dam is currently unavailable, its last inspection in May 2019 deemed it to have a low hazard potential. The dam's emergency action plan status, risk management measures, and inundation maps are not explicitly provided in the data, suggesting areas for improvement in emergency preparedness and response protocols for this recreational structure.
For water resource and climate enthusiasts, Wilkinson Pond Dam serves as a notable feature in the landscape of Madison County, Illinois, offering recreational opportunities while also highlighting the importance of regular inspection and maintenance to ensure the safety and integrity of dams in the face of potential risks and hazards. Its location along the Rocky Fork River and its design as an earth dam with buttress core types demonstrate the intersection of human infrastructure with natural water systems, emphasizing the need for sustainable management practices and proactive risk assessment in the face of changing environmental conditions.

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.
