Whalon Lake stands as a premier 81-acre fishing destination in Bolingbrook, Illinois, transformed from a former limestone quarry into one of Will County's most accessible and diverse angling opportunities. This gravel pit lake, owned and operated by the Forest Preserve District of Will County in cooperation with the Illinois Department of Natural Resources, offers exceptional fishing in a scenic setting surrounded by wetlands and prairie. With an average depth of 15 feet and a maximum depth approaching 100 feet, the lake provides varied underwater structure and habitat zones that support a thriving multi-species fishery. Fed primarily by groundwater with occasional input from the adjacent DuPage River during high water events, Whalon Lake maintains good water quality and clarity throughout the fishing season.
