Where the record came from

Canyon Lake is one of the South Dakota lakes we grade. It holds a Grade A water-quality score today, based on clarity, phosphorus, and chlorophyll-a samples from the EPA Water Quality Portal — a useful check on whether the water that produced a record fish still fishes well.

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 South Dakota

9 of South Dakota's 20 standing records are heavier than the 24 lb 8 oz brown trout — unsurprising, since record weight tracks species size more than anything about the water. 4 South Dakota records have stood longer, the brown trout mark dating to 1990.
