Rules change by area and can change mid-season. We explain what the rules mean and always link you to the official source — we never copy a limit table and call it current.
Licences — what you need
- • A fishing licence is required; a salmonid stamp is needed for Lake Michigan salmon/trout, an inland trout stamp for stocked trout waters, and a Lake Michigan perch/salmon framework applies on the big lake.
- • Licences run April to March — an easy renewal trap.
How the rules are organized
- • Statewide rules form the base, with a long site-specific list: many Illinois lakes and the Lake Michigan shoreline carry their own regulations published in the annual digest.
- • Border waters (Mississippi, Ohio, Wabash, Lake Michigan) follow shared frameworks.
Good to know — common mistakes
- • Site-specific regulations are the Illinois trap — two lakes an hour apart can have different bass and crappie rules; the digest lists them by site name.
- • Lake Michigan salmon fishing requires the salmonid stamp even from shore, and snagging is legal only in specifically designated areas/seasons.
- • Two-pole and line limits are statewide structure, with site-specific waters sometimes allowing more.
- • Ice fishing shelter rules and permitted waters vary by site; not every frozen lake is open to ice fishing.

This page is a plain-language summary, not the law. Regulations change — including in-season by official notice — and if anything here disagrees with the official source, the official source governs.
AnglerPlan is an information service, not a regulator. If anything here disagrees with an official source, the official source wins — and please tell us so we can fix it.
