What special fishing regulations apply at Lake Michigan?

Lake Michigan carries 2 special-regulation overlays that override Illinois' statewide 2026 rules, covering Smallmouth bass. One of them reads: "63 miles of IL shoreline; Lake Michigan Salmon Stamp REQUIRED ($6.50 res / $6.50 NR) to take chinook + coho + lake trout + brown + rainbow / steelhead; 5 / day combined salmon + trout (10 in min all trout + salmon) but no more than 2 lake trout / day; large + smallmouth bass 21 in min, 1 / day; yellow perch 15 / day, closed May 1 – June 15." Every overlay on this water body is listed in full above.

Do I need a fishing license to fish Lake Michigan?

Yes. Lake Michigan is in Illinois, so a valid Illinois fishing license is required just as it is anywhere else in the state, issued by Illinois Department of Natural Resources. The special regulations on this page change the bag, size, slot, or gear rules for Lake Michigan; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Illinois rules.

Do Lake Michigan's special rules replace Illinois' statewide limits?

Only where they conflict. Illinois' statewide 2026 regulations apply on Lake Michigan by default; the overlays above replace the matching statewide rules for the species or gear they name, while everything not specifically overridden still follows the statewide rule. When a water-body rule and the statewide rule disagree, the water-body rule wins.

Which species have special rules on Lake Michigan?

Smallmouth bass has a water-body-specific rule on Lake Michigan, each linking to its full Illinois regulations above. Species not listed here follow the statewide Illinois limits.
