Indiana State Record Brown Trout: 29 lb 5 oz
The Indiana state record brown trout weighed 29 lb 5 oz. It was caught in 2006 from Lake Michigan in Lake County by Glen Duesing, and the Indiana DNR still recognizes it as the state mark 20 years later.
Where the record came from
The record came from Lake Michigan in Lake 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 Indiana 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 Indiana
