Summary
The dam, primarily owned by a private entity, stands at a height of 24 feet and has a length of 230 feet, holding a storage capacity of 54 acre-feet. Situated on the Tributary of Crow Creek, the dam is regulated and inspected by the Illinois Department of Natural Resources to ensure its safety and functionality.
Despite being classified as having a low hazard potential, Maupin Lake Dam is subject to moderate risk assessment due to its age and condition assessment being unavailable. The dam features an uncontrolled spillway and outlet gates, indicating its reliance on natural overflow mechanisms. While the emergency action plan status and risk management measures remain unclear, the dam's location and purpose highlight its importance in providing recreational opportunities and water resource management for the local community.
In the event of any emergencies or unforeseen circumstances, the dam at Maupin Lake is equipped with emergency contacts and regular inspection schedules to mitigate potential risks. As water resource and climate enthusiasts, understanding the critical role of dams like Maupin Lake in sustaining water bodies and ensuring public safety underscores the importance of continued monitoring and maintenance to safeguard our natural environment and recreational areas for future generations to enjoy.

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.
