Fish Status



One of the few species that survived the winter kill, black crappie were surprisingly common in the 2015 fall survey. Although a few larger adults were collected, the majority of the population is dominated by younger fish; the average length collected in the 2015 survey measured 6.5”. No white crappie were recovered.



This species has also been stocked, along with redear sunfish, at fingerling size. Still in the developmental stage the majority of what was collected in the fall of 2015 measured less than 4”.



Due to an extended period of high water, common carp gained access to the lake from the nearby creek. Efforts have been initiated to remove/reduce the carp population before it has a chance to become too problematic. Anglers are encouraged to harvest their catch.



This species has been, and will continue to be stocked to attain reasonable population density, which should provide quality angling. Site Regulation: 6 fish daily creel limit.



Since the winter kill event, several stockings of largemouth bass have occurred, which included fingerlings as well as adults. The fall 2015 survey yielded multiple year classes, but the population remains in a re-building phase with most of the bass collected less than 12”. Until the population has completely recovered, a catch-and-release-only regulation is in effect for black bass.

Location: Lake Milliken is located in Will County within the confines of the Des Plaines Conservation Area, 3 miles west of Wilmington off River Road and just minutes from Interstate 55.

Description: Lake Milliken was constructed in 1961, a borrow pit resulting from the construction of Interstate 55. A fairly shallow, fertile lake, Milliken has a maximum depth of 8 feet and an average depth of 4 feet. Intensified management of aquatic vegetation is required to provide fishermen with easier angling opportunity on the main basin. The south end, which is relatively shallow, generally supports very lush aquatic plant growth. There is no boat access, and watercraft are not permitted.

History and Status of the Sport Fishery: Due to the severity of the winter of 2013-14, Lake Milliken experienced a near-complete fish kill. Currently the lake is in a "recovery mode", which involves an aggressive restocking program coupled with restrictive harvest limits on selected species. Lake Milliken also receives catchable rainbow trout for the spring season.

The fishery is monitored on a biennial basis, utilizing a combination of electrofishing and netting (both gill net and trap net). Aquatic vegetation treatments are conducted on an annual basis (if required) and in the most recent years have incorporated early spring fluridone applications to arrest the growth of curleyleaf pondweed. For habitat considerations, the far south portion of the lake is not treated.

Additional Lake Information: Two pole and line fishing only.
