Fish Status


Very Good

In 2019, 39% of the bluegill collected were longer than 6”, but these data vary greatly depending on the amount of vegetation present and sampled. Fish ranged from 1” to 8.5” and topped the scale at 0.47 lbs.. 29% of the bluegill collected were over 7” long and 8% exceeded 8” long. Bluegills approaching 9.5” long were reported by a few lucky anglers this fall!



This species is maintained through natural reproduction and are common in river systems. Since the Chain is part of a river system, these fish are a significant predator, relatively abundant and caught by a lot of anglers. Channel catfish ranged in size from 10” to 28” long and weighed up to 7 lbs. In 2019, 90% of the channel catfish collected exceeded 18” in length, 32% were over 22” long and 10% were over 24” long.



Both black crappie and white crappie were collected in 2019. Fish measured between 2” and 15” long and weighed up to 1.7 lbs. 83% of black crappie and 62% of white crappie exceeded 9”, and 14% of black crappie and 31% of white crappie exceeded 11” long.



Though not common, flathead catfish are present in the Chain O Lakes above the McHenry Dam, but commonly targeted below the McHenry Dam south to Dayton. Site Regulation: 3 fish daily limit; one fish greater than 28" and 2 fish less than 28".



In 2019, bass were collected at a rate of 30 fish/hr. Fish measured from 2” - 20” long, 50% of the bass collected were over 12” long and sexually mature, 25% exceeded 14 inches (legal size), 16% were over 15” long, 12% were over 16” long and 3% were over 18”. This is a well-balanced population that supports quality panfish development and supports bass angling opportunities. Site Regulation: 6 fish daily limit, 14" minimum length (No more than 3 fish can be smallmouth bass, smallmouth must be released immediately between April 1 to June 15, no possession)


Very Good

Muskie are managed for high catch rates, and the longevity of the stocking program has allowed females to grow LARGE! The average muskie is 36” long, but fish up to 51” are caught and regularly reported. In the Chain, it takes at least 12 years for a muskie to reach 48” (legal length) and about 15 years to reach 51”+. Male muskie occasionally grow beyond 40” long, but females easily grow through it and are the longest fish in a system. Muskie are surveyed each year, in spring nets, to assess growth. Females weighing over 30 pounds are regularly collected with our largest-ever weighing 36.2 pounds (in 2007)! There are some really nice fish in the Chain! Site Regulation: 1 fish daily limit, 48" minimum length.



Northern pike are present in the system and are maintained through natural reproduction. Site Regulation: 3 fish daily limit, 24" minimum length.



Smallmouth bass make up about 10% of the total bass catch. They maintain themselves with natural reproduction. Fish up to 18" are collected during surveys. Site Regulation: Daily limit of 3 fish; smallmouth must be released immediately between April 1 to June 15 (no possession).


Very Good

Site Regulation: 4 fish daily limit. Minimum Length regulation: 4 fish creel, 14" to 18" fish harvestable size, protective slot (no possession) 18" to 24", only 1 fish greater than 24" can be in the creel '>The Chain O Lakes is a brood source for the State Hatchery System, so it is managed to produce large walleye! During the biennial fall survey (2019), walleye were collected at a rate of 19.8 fish/hr. Fish ranged from 3” to 27” long. In spring, fish beyond 10 lbs. are collected (and released because they're too big for Hatchery use). All brood fish are returned to Lake Marie after being processed by the Hatchery. Fall 2019 data indicated 45% of the walleye sampled exceeded 14” long, 34% were over 18” long and 11% of the sample was over 24” long. The slot regulation protects female fish and promotes harvest of males. Site Regulation: 4 fish daily limit. Minimum Length regulation: 4 fish creel, 14" to 18" fish harvestable size, protective slot (no possession) 18" to 24", only 1 fish greater than 24" can be in the creel

Location: The Fox Chain O' Lakes is located 50 miles northwest of Chicago off Illinois Route 173 and U.S. Route 12 near the cities of Antioch, Fox Lake, and McHenry.

Description: The Fox Chain O' Lakes are unique from other major bodies of water in the state in that they were formed by glaciers thousands of years ago. Composed of 9 major lakes interconnected by channels, the Fox Chain O' Lakes is classified as a public navigable waterway managed under the authority of the Department of Natural Resources and the Fox Waterway Agency to provide a variety of water oriented recreational activities. There is a total of 7110.0 acres above the Stratton Dam and 1100 acres between the Algonquin and Stratton dams. Lake Catherine: 149.5 acres; Channel Lake: 348.5 acres; Lake Marie: 585.0 acres; Bluff Lake: 92.4 acres; Grass Lake: 1451.4 acres; Petite Lake: 234.5 acres; Fox/Nippersink Lake: 2376.8 acres; Pistakee Lake: 1715.7 acres.

There are state-owned FREE boat ramps available at Chain O Lakes State Park; private (for fee) launches are available throughout the system. Concessions are available at Chain O Lakes State Park and the McHenry Dam, offering fishing boat and motor rental, canoe/kayak rentals, live bait, tackle, ice, food, and soft drinks. Boat rentals, restaurants, bait/tackle and guide services are available via private vendors throughout the system. Fish cleaning facilities are NOT available in State Parks or at the McHenry Dam.

History and Status of the Sport Fishery: The Division of Fisheries has been actively monitoring the status of Fox Chain O' Lakes fishery for over 60 years (1954 to present). We usually collect between 35 and 40 fish species during our biennial fish surveys. Three fish species have voluntarily become established in the Fox Chain O' Lakes; yellow bass (1973, with a significant die-off in 1995 and 1997), freshwater drum (1992) and gizzard shad (2007).

The Fox Chain is annually stocked with 243,000 2” walleye fingerlings, 2 million walleye fry, and between 2000 - 3000 muskie fingerlings. 24,000 4” – 6” largemouth bass fingerlings are stocked every year. Natural reproduction maintains all other species, including northern pike.

Additional Lake Information: The Fox Waterway Agency requires an annual user fee/sticker for watercraft utilizing the Fox Chain O' Lakes and the Fox River from the Illinois state line to Algonquin Dam. Please contact them for their annual fee schedule and an application.

Trot line fishing is permitted.

The State owns management jurisdiction for the Chain O Lakes and allows homeowners to treat vegetation in front of their homes by hiring a Licensed Commercial Applicator and obtaining a Letter of Permission (LOP) from the Division of Fisheries.
