Summary
Completed in 2007, this earth dam stands at a height of 12 feet and a length of 3500 feet with a storage capacity of 146 acre-feet. The dam is state-regulated, permitted, inspected, and enforced by the Illinois Department of Natural Resources, ensuring its compliance with safety standards and regulations.
With a low hazard potential and a moderate risk assessment rating, Pinnacle Pond 5 Dam serves as a critical infrastructure for flood risk reduction in the area. The dam features an uncontrolled spillway with a width of 122 feet and uncontrolled outlet gates. While the condition assessment is currently not available, the last inspection in May 2018 indicated a 5-year inspection frequency to monitor the dam's structural integrity and safety. The dam's emergency action plan status, inundation maps, and risk management measures are not specified in the data, highlighting potential areas for further improvement and preparedness.
Overall, Pinnacle Pond 5 Dam plays a vital role in mitigating flood risks along Mink Creek in Will County, Illinois. As a privately owned structure, it underscores the importance of collaboration between private owners and state regulatory agencies to ensure the safety and effectiveness of water resource management infrastructure. Continued monitoring, inspection, and adherence to safety protocols will be essential in maintaining the dam's functionality and protecting the surrounding community from potential flooding events.

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.
