Summary
Built in 2003 by IDNR-OWR, this state-regulated earth dam stands at 44 feet high and stretches 448 feet in length, with a storage capacity of 672 acre-feet. The dam's primary purpose is to create a fish and wildlife pond, covering a surface area of 34.3 acres and serving as a habitat for various species.
Despite its high hazard potential, Drake Lake Dam has not undergone a recent condition assessment. However, regular state inspections ensure its structural integrity and safety. The dam features an uncontrolled spillway with a width of 245 feet and a maximum discharge capacity of 2727 cubic feet per second. While the risk assessment indicates a moderate level of risk, there is a lack of detailed risk management measures and emergency action plans in place.
Water resource and climate enthusiasts visiting Drake Lake Dam can appreciate its contribution to local ecology and recreation opportunities. With its scenic surroundings and vital role in supporting wildlife, this dam stands as a testament to the importance of sustainable water management practices in 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.
