Summary
The dam, completed in 1968, serves multiple purposes, including recreation and water storage. With a height of 55 feet and a length of 1370 feet, it holds a normal storage capacity of 26,008 acre-feet and a maximum storage of 36,341 acre-feet. The dam is situated on the Little Doza Creek, providing essential water resource management for the region.
Managed by a public utility, the Baldwin Plant Cooling Lake Dam is regulated by the Illinois Department of Natural Resources. It has a controlled spillway with a width of 24 feet and a maximum discharge capacity of 748 cubic feet per second. Despite its high hazard potential, the dam's condition assessment is currently not available, highlighting the need for regular inspection and maintenance to ensure its structural integrity and safety. The risk assessment for the dam is categorized as very high, underscoring the importance of effective risk management measures.
In the face of climate change and fluctuating water resources, the Baldwin Plant Cooling Lake Dam plays a critical role in the water infrastructure of Randolph County, Illinois. Its strategic location and multi-purpose design make it a key asset for both water management and recreational activities in the area. As enthusiasts for water resources and climate resilience, understanding and monitoring the condition of dams like Baldwin Plant Cooling Lake Dam is crucial for sustainable water resource management and disaster preparedness efforts.

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.
