Fishing in Illinois reflects this diversity, offering a range of experiences.

You can troll the vast waters of Lake Michigan or cast your line along some of the state’s 86,000 miles of rivers.

Whether you’re seeking adventure in the Mississippi River or looking to catch Bass in cooling lakes, Illinois provides a variety of angling opportunities.

Types of Fish in Illinois

Largemouth Bass

Largemouth Bass in the Illinois Waterways

Largemouth Bass are prevalent throughout Illinois waterways and are a prime target for anglers.

They thrive in warmer waters but can be found year-round thanks to power plant cooling lakes.

One of the best times to fish for Largemouth Bass is in October, as they aggressively feed in preparation for winter.

Smallmouth Bass

Smallmouth Bass are known for their agility and strength, often found in northern Illinois rivers and Lake Michigan.

Anglers prize them for their spirited fight, especially on a fly rod.

Monroe Harbor provides exceptional Smallmouth Bass fishing, particularly around structures during spring and fall.


Trout Fishing in Lake Michigan

Illinois offers excellent opportunities for catching Brown, Rainbow, and Lake Trout, primarily in Lake Michigan. Rainbow and Lake Trout are the most common species.

The Illinois Department of Natural Resources stocks over 80,000 Rainbow Trout annually in rivers and lakes, with the season opening on the first Sunday in April and the third Sunday in October for specific waterways.

Popular Trout fishing spots include:

  • Apple River near Canyon State Park: Known for its scenic beauty and abundant Trout during biannual stocking.

  • Pine Creek, a Rock River tributary: A rare location for summer Rainbow Trout fishing.


Lake Michigan is the focal point for Salmon fishing in Illinois, hosting species like Chinook (King) and Coho (Silver) Salmon.

These Pacific Salmon were introduced in the 1800s and continue to provide thrilling fishing experiences.

Nearshore Coho fishing starts in April, while deeper waters yield both species during the summer months.


Musky Fishing in Illinois

Muskies, renowned for their challenge and thrill, are apex predators and a coveted catch for dedicated anglers.

Despite their reputation as the “fish of 10,000 casts,” Illinois offers relatively easier Musky fishing due to well-stocked lakes.

The Fox Chain O’Lakes is a top destination for trolling and casting for Musky in the fall.


Illinois is famous for its Catfishing, highlighted by a world-record Blue Catfish caught in the Mississippi River.

Blue, Flathead, and Channel Catfish are prevalent throughout the state.

The Ohio River is a prime location for Catfish fishing, with Channel Catfish thriving on spilled grain from barges and grain elevators.


Crappie - Illinois Fishing

Crappies, both White and Black, are among the most popular and tasty fish in Illinois.

They inhabit various lakes, but some of the best Crappie fishing occurs in the Mississippi River’s sloughs and backwaters during spring.

Other Common Fish in Illinois

  • Bluegill: The state fish of Illinois, Bluegill, are abundant and well-regarded for their taste. Rend Lake is a notable location where Bluegill can grow larger than average.
  • Walleye: A favorite for their culinary value, Walleye fishing is excellent in northern rivers and streams, particularly in the spring.
  • Northern Pike: These predatory fish frequent glacial lakes and rivers north of Peoria. The Des Plaines River is a hotspot for Pike, especially between Lyons and Lemont.
