Summary
The dam at Fresh Water Lake is an earth dam with a height of 28 feet, providing a storage capacity of 1540 acre-feet. The primary purpose of the dam is to supply water, and it is considered to have a significant hazard potential.
Located in Macoupin County, Fresh Water Lake is managed by private owners and falls under state jurisdiction with required permitting, inspection, and enforcement by the IDNR. The Mine Safety and Health Administration oversees regulatory aspects of the dam, ensuring compliance with safety standards. While the dam's condition assessment is currently not available, its hazard potential indicates the need for ongoing monitoring and risk management measures to protect the surrounding community and environment.
Enthusiasts of water resources and climate in Illinois can appreciate the significance of Fresh Water Lake as a vital water supply source in the region. With its strategic location and state-regulated status, the lake serves as a critical infrastructure for water management and conservation efforts in the area. Ongoing inspection and maintenance are essential to ensure the safety and sustainability of Fresh Water Lake for both current and future generations of residents and wildlife in Macoupin County.

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.
