Summary
Standing at 40 feet in height and stretching 486 feet in length, this earth dam on the tributary of Clark Branch offers a storage capacity of 143 acre-feet for water enthusiasts to enjoy. Despite being categorized as having a low hazard potential, the dam is subject to state regulation, inspection, and enforcement by the Illinois Department of Natural Resources.
The dam's spillway is uncontrolled, with a width of 0, and outlet gates are similarly uncontrolled. The last inspection in September 2018 indicated a moderate risk level, and the condition assessment is currently not available. While emergency action plans and risk management measures are not specified, the dam meets state guidelines for operation and maintenance. Located in a scenic offstream area, Lake Holiday Dam serves as a vital resource for water recreation in the region, offering a tranquil setting for outdoor activities.
Despite its age, Lake Holiday Dam continues to provide a safe and enjoyable environment for visitors seeking water-based recreational opportunities. With its historical significance and importance to the local community, the dam stands as a testament to the enduring appeal of water resources in the face of changing climates and conservation efforts. As a privately owned structure, it remains a valuable asset for both leisure and conservation purposes, reflecting the harmonious coexistence of human activity and environmental stewardship in the realm of water management.

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.
