Summary
This structure stands at a height of 40 feet with a length of 400 feet, providing a normal storage capacity of 70 acre-feet across its 7-acre surface area. The dam is regulated by the Illinois Department of Natural Resources and has a low hazard potential, making it a crucial component for managing water resources in the area.
Despite being uncontrolled, the dam's spillway has a width of 19 feet and a maximum discharge capacity of 170 cubic feet per second, ensuring adequate water flow management. The structure is situated along the TR-Little Embarrass E river/stream and is surrounded by a drainage area of 0.09 square miles. With a moderate risk assessment rating of 3, ongoing inspections and enforcement by the state regulatory agency help ensure the safety and functionality of Curtis Brothers Pond Dam for both recreational and ecological purposes. Enthusiasts of water resources and climate will find this dam to be a noteworthy example of sustainable infrastructure supporting wildlife conservation and outdoor recreation in Coles County, Illinois.

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.
