Summary

Standing at a height of 40 feet and stretching 700 feet in length, this dam has a maximum storage capacity of 155 acre-feet and a normal storage level of 112 acre-feet. The dam is situated on the Trib Sycamore Creek and is regulated by the Illinois Department of Natural Resources.

Despite being classified as having a low hazard potential, Aquaculture Lake Dam presents a moderate risk level, with a spillway type of "Uncontrolled" and a spillway width of 17 feet. The dam has not been modified in recent years and does not have outlet gates. The last inspection of the dam took place in June 2017, with an inspection frequency of every 5 years. Although the condition assessment is currently not available, the dam is monitored by state agencies for enforcement, permitting, and inspection to ensure public safety.

For water resource and climate enthusiasts, Aquaculture Lake Dam offers a fascinating example of how man-made structures can serve both recreational and environmental purposes in a controlled manner. With its moderate risk level and low hazard potential, this dam represents a balance between human enjoyment and safety measures, showcasing the importance of proper regulation and maintenance in managing water resources effectively.

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.
