Summary
Constructed in 2008 by SHEAFFER INTERNATIONAL, L.L.C., this earth dam stands at a height of 17 feet and has a storage capacity of 355 acre-feet. Despite its modest size, the dam holds a high hazard potential, reflecting the importance of proper maintenance and monitoring to ensure public safety.
Managed by the local government and regulated by the Illinois Department of Natural Resources, the Cortland Water Reclamation Facility Cell 3 Dam undergoes regular inspections to assess its condition and mitigate risks. With a moderate risk assessment rating of 3, the dam is subject to emergency action plans and risk management measures to address any potential hazards. The presence of an uncontrolled spillway highlights the need for proactive safety measures to prevent flooding and protect surrounding areas.
As a key component of the water infrastructure in the region, the Cortland Water Reclamation Facility Cell 3 Dam plays a crucial role in supporting local agriculture and water management efforts. Its construction and maintenance demonstrate the ongoing commitment to sustainable water resource management in Illinois. Climate and water resource enthusiasts will find the dam's design and functionality a captivating example of how engineering and environmental stewardship intersect to meet the needs of communities while safeguarding natural 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.
