Owned privately, this earth dam with a buttress core stands at a height of 20 feet and has a length of 815 feet. The dam has a maximum storage capacity of 78 acre-feet and a normal storage capacity of 61 acre-feet, making it a valuable resource for water supply and recreational activities in the area.
Although classified as having a low hazard potential, Martel Lake Dam is regulated by the Illinois Department of Natural Resources (IDNR) and undergoes regular inspections, with the last one conducted in June 2016. The spillway, which is uncontrolled, has a width of 30 feet, and the dam is situated on Trib Lake Creek. Despite its moderate risk assessment, the dam has not had its Emergency Action Plan (EAP) updated recently, raising concerns about its readiness in case of emergencies. With its picturesque location and important role in water management, Martel Lake Dam is a significant feature for water resource and climate enthusiasts to explore and monitor.
