2026 regulation year

Montana Northern pike 2026 — Season, Bag Limit, Size Rules

Esox lucius

Last updated June 8, 2026

Montana northern pike fishery is anchored by the Missouri River reservoir + prairie system of central + eastern MT — Fort Peck Reservoir (245,000-acre Missouri main-stem reservoir, country's fifth-largest by surface area) is the flagship trophy pike water, producing 15-20 lb fish from its weedy bays + flooded timber; Tiber Reservoir / Lake Elwell, Nelson Reservoir, Fresno Reservoir, Lake Frances + the lower Missouri carry strong pike populations. Northern pike (Esox lucius) are native only to the Hudson Bay drainage of far-northeastern MT but were widely (and often illegally) introduced elsewhere — FWP manages them as a non-native, harvest-encouraged species across most of the state, and as an invasive to be eradicated where they threaten native trout (Lake Mary Ronan + listed western waters require every pike to be killed immediately + reported to FWP). FWP sets pike limits by district: Western Fishing District 15 / day with no possession limit, Central + Eastern 10 / day. Pike spawn in shallow flooded vegetation immediately after ice-out (April – May), the densest fishing window of the year, then hold along weed edges through summer. The eastern prairie reservoirs (Fort Peck + Nelson + Fresno + Tiber) produce the state's biggest pike; the warm, fertile bays of Fort Peck's Big Dry + Pines + Hell Creek arms are the trophy zones. Open year-round statewide.
