Iowa Channel catfish 2026 — Season, Bag Limit, Size Rules
Ictalurus punctatus
Last updated
Iowa channel catfish fishery is one of the densest in the Midwest — the Mississippi River main stem (Pools 9-22 along the IA/WI + IA/IL + IA/MO boundary), the Missouri River main stem (IA/NE + IA/MO boundary from Sioux City IA to the MO state line), the four USACE flood-control reservoirs (Red Rock + Saylorville + Coralville + Rathbun), and the Des Moines River + Iowa River + Cedar River + Wapsipinicon River + Maquoketa River + Skunk River main-stem river tier all support naturally-reproducing channel catfish populations. The Iowa DNR statewide standard rule is an 8-fish combined daily aggregate across channel + blue + flathead catfish (Iowa sets NO separate flathead limit — all three catfish share one combined aggregate) with no statewide minimum on inland lakes, rising to 15 / day on interior streams + the four USACE reservoirs and no daily limit at all on the Mississippi River — one of the higher catfish bags in the Midwest (compared to MO 4-5/day on most waters + MN 5/day + WI 25/day on Mississippi but generally 5-10/day elsewhere). The Mississippi River main stem carries trophy channel catfish on the wing-dam + lock-and-dam tailwater structure throughout Pools 9-22; the Missouri River main stem carries trophy channel + blue + flathead catfish on the snag + log + bend structure throughout the 175-mile IA reach. Rathbun Lake (11,000 acres on the Chariton River) is the IA state-record flathead catfish water (81 lb 0 oz, 1988) and one of Iowa's premier trophy catfish reservoirs alongside the river main-stem tier. Iowa DNR stocks ~5 million channel catfish fingerlings annually statewide across the four USACE reservoirs + farm-pond + watershed-lake program via the Rathbun + Mt. Ayr State Fish Hatcheries.
