Ohio State Record Channel Catfish: 37 lb 10 oz
The Ohio state record channel catfish weighed 37 lb 10 oz and measured 41.5 inches. It was caught in 1992 from LaDue Reservoir by Gus J. Gronowski, and the Ohio Division of Wildlife still recognizes it as the state mark 34 years later.
Where the record came from
The record came from LaDue Reservoir. 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 Ohio 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 Ohio
3 of Ohio's 21 standing records are heavier than the 37 lb 10 oz channel catfish — unsurprising, since record weight tracks species size more than anything about the water. 9 Ohio records have stood longer, the channel catfish mark dating to 1992.
