Summary

The dam, constructed by McDonough Associates Inc, stands at a height of 7 feet and spans a length of 245 feet, with a storage capacity of 150 acre-feet. The dam is situated on Flint Creek and has a low hazard potential, with a moderate risk assessment rating.

Although Labuy Lake Dam is privately owned, it falls under the regulatory jurisdiction of the Illinois Department of Natural Resources, which oversees its permitting, inspection, and enforcement. The dam features an uncontrolled spillway and outlet gates, with a maximum discharge capacity of 380 cubic feet per second. Despite its low hazard potential, the dam's risk management measures are not specified, highlighting the importance of ongoing monitoring and maintenance to ensure its safety and integrity.

Water resource and climate enthusiasts interested in Labuy Lake Dam can appreciate its role in providing recreational opportunities while also recognizing the need for effective risk management and maintenance practices to mitigate potential hazards. As a key structure on Flint Creek, the dam's location in Cook County, Illinois, underscores the importance of balancing human enjoyment with environmental stewardship to ensure the long-term sustainability of this vital water resource.

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.
