Summary
The dam's primary purpose is for fire protection, stock, or small fish pond. With a dam height of 15 feet and a length of 660 feet, it has a storage capacity of 86 acre-feet and a normal storage of 44 acre-feet. The dam is earth-filled with a buttress core type and an uncontrolled spillway type.
Owned privately, Huegelys Lake Dam is regulated by the Illinois Department of Natural Resources and undergoes state inspections, permitting, and enforcement. The dam has a low hazard potential and a moderate risk assessment rating of 3. While the condition assessment is not available, the dam is reported to meet regulatory guidelines. The emergency action plan status, including inundation maps, emergency contacts, and risk management measures, is not currently available.
Water resource and climate enthusiasts interested in Huegelys Lake Dam can appreciate its role in fire protection and wildlife support in the Washington County area of Illinois. The dam's design by USDA NRCS and its state-regulated status add to its significance in the local water management landscape. With a focus on safety and risk management, the dam's operational aspects and emergency preparedness are areas where further information may enhance understanding of its overall impact and importance in the region.

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.
