Summary
The dam, standing at a height of 10 feet and stretching 250 feet in length, regulates Little Mud Creek and has a maximum storage capacity of 184 acre-feet. The dam is owned privately and is managed by the Illinois Department of Natural Resources (IDNR), with state regulation, inspection, and enforcement in place to ensure its safety and compliance.
The dam's spillway is uncontrolled, and it has a low hazard potential with a moderate risk assessment rating of 3. Despite its age, the condition assessment of Kellart Lake Dam is currently not available, with the last inspection conducted in October 2014. The dam's emergency action plan status, risk management measures, and inundation maps are also not readily accessible. With its tranquil setting and recreational purpose, Kellart Lake Dam serves as a vital water resource for the local community while maintaining a moderate risk level that warrants continued monitoring and maintenance.
Enthusiasts of water resources and climate will find Kellart Lake Dam an intriguing structure in the picturesque landscape of Iroquois County, Illinois. Managed by private owners and regulated by state authorities, the dam provides a recreational haven along with essential water management functions. Its design by the SCS and proximity to Little Mud Creek make it a notable feature in the area's water infrastructure. As efforts continue to maintain its safety and compliance, Kellart Lake Dam stands as a testament to the importance of sustainable water resource management in ensuring the well-being of both the environment and the community.

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.
