Summary
Completed in 1970, this earth dam stands at a height of 30 feet and spans 245 feet in length, providing a serene backdrop for various outdoor activities. The dam's primary purpose is recreation, with a storage capacity of 107 acre-feet and a normal storage level of 68 acre-feet.
Maintained by a private owner, Keeven Lake Dam is regulated by the Illinois Department of Natural Resources (IDNR), ensuring that it meets state inspection and enforcement standards. Despite having a low hazard potential, the dam's risk assessment is rated as moderate, highlighting the importance of ongoing monitoring and risk management measures. The dam features an uncontrolled spillway with a width of 85 feet and has not undergone any major modifications since its completion.
Water resource and climate enthusiasts can appreciate Keeven Lake Dam not only for its recreational value but also for its role in water management and safety. With its picturesque location and moderate risk level, the dam stands as a testament to the importance of responsible stewardship of our natural resources in the face of changing environmental conditions.

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.
