Summary
The dam, standing at a height of 32 feet and stretching over 400 feet in length, holds a maximum storage capacity of 71 acre-feet and a normal storage capacity of 58 acre-feet. Situated along the TRIB HORSE CREEK, this earth dam with buttress core type is under the regulatory oversight of the Illinois Department of Natural Resources, ensuring proper inspection, permitting, and enforcement measures are in place.
Despite its low hazard potential, the dam at Waterloo Sportsman Club Lake 2 is subject to regular inspections every five years to assess its condition and mitigate any risks associated with its operation. While the current condition assessment is not available, the dam's risk assessment indicates a moderate level of risk. The dam features an uncontrolled spillway, with a width of 44 feet, and outlet gates that are also uncontrolled. Although an Emergency Action Plan (EAP) status is not provided, it is crucial for the dam owner to have updated emergency contacts and ensure that the EAP meets safety guidelines to handle any potential incidents effectively.
Waterloo Sportsman Club Lake 2 Dam stands as a testament to the importance of water resource management and recreational infrastructure in Monroe County, Illinois. With its strategic location, design features, and regulatory oversight, the dam provides a safe and enjoyable environment for visitors while also highlighting the need for ongoing maintenance and risk assessment to ensure long-term safety and sustainability.

Dam Data Reference
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.
