South Dakota Channel catfish 2026 — Season, Bag Limit, Size Rules

Ictalurus punctatus

Last updated June 9, 2026

South Dakota channel catfish fishery is anchored by the lower James River (the 'Jim') and the Missouri River main stem below the four USACE reservoirs. The lower James River — a slow, turbid prairie river winding through southeastern SD to its mouth on the Missouri near Yankton — is the state's premier channel-catfish water and the focus of SDGFP's Lower James River Catfish Study; its long, warm, nutrient-rich reaches grow dense channel-cat populations and the occasional true trophy. The Missouri River main stem (the Fort Randall Dam tailwater, the Gavins Point Dam tailwater, and the 59-mile free-flowing Missouri National Recreational River below Gavins Point) carries channel + blue + flathead catfish, and the lower SD Missouri holds genuine blue catfish (their range extends upstream from the lower river). SDGFP sets a statewide catfish rule of 10 fish per day in any combination of channel, blue, and flathead (only one flathead 30 inches or longer per day), 20 in possession, with no minimum length on channel catfish. On the Missouri River inland reaches catfish carry NO daily or possession limit (only one flathead 30 in+ per day) — catfish are managed as abundant rough fish there and may be taken year-round, day or night. On the NE/SD border waters channel catfish are 10 / day (20 possession) and flathead 5 / day (one 30 in+). SD's record is a story in itself: the legendary 55 lb 'channel catfish' caught by Roy Groves on the James River in 1949 was VOIDED in 2019 after SDGFP fisheries experts reidentified the fish in the old photo as a blue catfish, and the channel-catfish category was reopened (the 'Catrush 2019' campaign); the reopened channel-catfish record has stood comparatively modest (15 lb 4 oz as of 2020) and remains open to challenge.
