The dam is classified as an Earth dam with a height of 11 feet and a length of 125 feet, creating a reservoir with a normal storage capacity of 457 acre-feet. The dam is situated on a tributary of Indian Creek and is under the jurisdiction of the Illinois Department of Natural Resources.
With a high hazard potential and moderate risk assessment, Forest Lake Dam is subject to state regulation, inspection, and enforcement to ensure public safety. The dam features an uncontrolled spillway with a width of 175 feet and a maximum discharge of 1684 cubic feet per second. Despite its age, the dam's condition assessment is not available, indicating the need for ongoing monitoring and maintenance to mitigate risks associated with its structural integrity.
In the event of an emergency, there are no outlet gates or Emergency Action Plan (EAP) prepared for Forest Lake Dam. While the dam provides recreational opportunities and serves as a vital water resource in the area, continued evaluation and risk management measures will be crucial to safeguard the surrounding community and the environment in the face of changing climate conditions.
