Summary

The dam stands at a height of 26 feet and spans a length of 220 feet, with a storage capacity of 68 acre-feet. Situated on the Tributary of the Mississippi River, this earth dam with a buttress core serves primarily for recreational purposes, offering opportunities for fishing, boating, and other outdoor activities.

Managed and regulated by the Illinois Department of Natural Resources (IDNR), the dam is inspected regularly to ensure its safety and compliance with state regulations. With a low hazard potential and moderate risk assessment, the dam poses a minimal threat to the surrounding area. Despite a lack of available condition assessment data, the structure remains in good standing, with no significant issues reported.

While the dam features an uncontrolled spillway and outlet gates, emergency action plans and risk management measures are not currently documented. Nevertheless, the Fort Charters Sportsmans Club Lake Dam continues to provide a picturesque setting for water resource and climate enthusiasts to enjoy nature and recreation in Randolph County, Illinois.

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.
