Illinois State Record Walleye: 15 lb 1 oz
The Illinois state record walleye weighed 15 lb 1 oz. It was caught in 2012 from Pecatonica River in Winnebago County, and the Illinois DNR still recognizes it as the state mark 14 years later.
Where the record came from
The record came from Pecatonica River in Winnebago County. We don't carry a water-quality grade for it: our index covers standing lakes with enough EPA Water Quality Portal samples to score, which leaves out rivers and tributaries, Great Lakes water, and smaller ponds that are rarely sampled. Browse the Illinois lakes we do grade instead.

Each figure comes from that state's own fisheries agency. Agencies differ on what they certify — some recognize catch-and-release length records alongside weight — so treat this as a comparison of standing certified weights, not a single national list.
How it ranks inside Illinois
10 of Illinois's 19 standing records are heavier than the 15 lb 1 oz walleye — unsurprising, since record weight tracks species size more than anything about the water. 16 Illinois records have stood longer, the walleye mark dating to 2012.
