Summary
Built in 1968, this private dam serves primarily for recreation purposes, offering a tranquil escape for water resource and climate enthusiasts. With a height of 18 feet and a length of 550 feet, Fish Lake Dam holds a storage capacity of 64 acre-feet, providing a picturesque setting for outdoor activities.
Managed by the Illinois Department of Natural Resources, Fish Lake Dam boasts a low hazard potential and a moderate risk assessment rating. While the dam is equipped with uncontrolled spillways and outlet gates, regular inspections have ensured its structural integrity and safety. Despite its remote location in Browns, Illinois, the dam remains a popular destination for fishing, boating, and other recreational pursuits.
As a vital part of the local ecosystem, Fish Lake Dam plays a crucial role in maintaining the balance of the TRIB JORDAN CREEK watershed. With its serene surroundings and well-maintained facilities, this earth dam offers a peaceful retreat for visitors to connect with nature and appreciate the beauty of Illinois's water resources.

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.
