Where the record came from
The record came from Wisconsin River in Crawford 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.

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 Wisconsin
