Illinois State Record Fish 2026: All 19 Official Records
All 19 verified Illinois record fish from the Illinois DNR. The heaviest is the Blue Catfish at 124 lb, caught in 2005 on Mississippi River. The oldest standing record is the Sauger from 1967.
The official Illinois state-fishing-records list is kept by Illinois DNR. Records range from prized gamefish like walleye, muskie, and bass to less-targeted species, and every one has been weighed and verified to the agency's standards.
A state record marks what a species is capable of in Illinois water, and the lakes and rivers where those records were set point to the specific waters that have historically produced trophy-class fish. Reading the record-setting waters alongside their water-quality readings is a useful exercise: coldwater species like trout and salmon tend to come from the clearest, lowest-nutrient waters, while warm-water trophies can come from across the range.

How Illinois Records Are Verified
Illinois DNR requires that record-eligible fish be weighed on a certified scale, photographed, and verified by a fisheries biologist; some species also recognize catch-and-release length records. Each agency sets its own application form and filing deadline — check the official Illinois DNR records page for the current rules before submitting a claim.
Targeting a record? Many of these fish came from waters with strong populations of trophy-class fish — see the best fishing lakes ranking, state record fish in every state, and the Illinois lake directory.
