Summary

Completed in 1947, this earth dam stands at a height of 11 feet and has a storage capacity of 365 acre-feet, primarily used for recreation purposes. The dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its safety and integrity.

Despite its low hazard potential, the Elkville Country Club Reservoir Dam poses a high risk due to its age and condition assessment not being available. However, emergency preparedness measures such as an Emergency Action Plan (EAP) are not currently in place. The dam overlooks the Tributary of Little Muddy River, serving as a picturesque backdrop for outdoor activities such as fishing and boating. With a peaceful setting and ample storage capacity, this dam remains a valuable asset for both water resource and climate enthusiasts in the region.

While the Elkville Country Club Reservoir Dam may have some risk factors to consider, its historical significance and contribution to the community's recreational activities are undeniable. As efforts continue to mitigate potential hazards and improve emergency preparedness, this dam remains a key feature in the landscape of Desoto, Illinois. Water resource and climate enthusiasts can appreciate the beauty and functionality of this structure, while also advocating for its continued maintenance and safety measures to ensure its lasting impact on the local environment.

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.
