Illinois Spring Trout Fishing Season Opener

The 2021 Illinois Spring Trout Fishing Season opened Saturday, April 3 at 57 ponds, lakes and streams throughout the state.

The Illinois Department of Natural Resources stocks more than 80,000 rainbow trout in bodies of water where trout fishing is permitted during the spring season. All anglers must have a fishing license and an Inland Trout Stamp, unless they are under the age of 16, blind or disabled, or are an Illinois resident on leave from active duty in the Armed Forces. The daily catch limit for each angler is five trout. See the listing of stocked sites here.

Asian Carp: The Perfect Catch

In its continuing efforts to further reduce the spread of Asian Carp in our waterways, IDNR has embarked on an exciting new initiative to improve the perception — and ultimately increase human consumption — of these healthy, delicious fish.

The Illinois Hatchery System

Illinois is home to three very productive fish hatcheries — Jake Wolf Memorial, LaSalle and Little Grassy Fish Hatcheries. The Illinois Hatchery System is dedicated to enhancing fish populations in Illinois waters by producing adequate numbers of various species of fish to meet stocking demands statewide. In fact, at full capacity the system can produce over 50 million fish of 20 species! State hatcheries also work with other US hatcheries to obtain fish eggs and fry to supplement on-site production for certain species.

To learn more about our hatchery system, as well as the hours they are open for visits from the public, see our page here.

Stop the Spread of Invasive Species

Remove, Drain, Dry: As the boats come out of storage, we'd like to remind you to be aware of invasive species that pose a threat to our lands and waterways. To fight the spread of aquatic invaders, the IDNR is asking residents to "be a hero transport zero." The best way to stop the spread of invasive species is to remove, drain, and dry your boats after use in any Illinois waterway. Learn more here.
