2026 regulation year

Nebraska Largemouth bass 2026 — Season, Bag Limit, Size Rules

Micropterus salmoides

Last updated June 8, 2026

Nebraska largemouth bass fishery spans the major Sandhills + USACE + Bureau of Reclamation reservoirs + the ~1,500 natural Sandhills lakes + farm-pond tier across the eastern + central regions. Nebraska's inland black-bass rule is a flat 15-inch minimum statewide with no more than one fish 21 inches or longer in a 5-fish aggregate bag across largemouth + smallmouth + spotted bass — the 12-inch minimum applies ONLY to the Missouri River between Nebraska and Iowa/Missouri, there is no minimum on the Missouri River between Nebraska and South Dakota (including Lewis & Clark Lake), and selected Public Fishing Areas plus Patriot Park Lake (Omaha metro) carry a 21-inch minimum at one fish per day. The flagship reservoirs (Merritt + Lake McConaughy + Branched Oak + Pawnee + Harlan County + Calamus + Sherman + Box Butte) and the high-volume secondary tier (Conestoga + Wagon Train + Wehrspann + Cunningham SRA lakes) all run that same 15-inch / 5-fish-aggregate inland standard. Open year-round statewide — March – May pre-spawn + spawn is the densest fishing window. Nebraska state-record largemouth bass 10 lb 11 oz (private pond, 1965). NGPC stocks Florida-strain + intergrade largemouth selectively on Branched Oak + Pawnee + quality-management reservoirs to support trophy potential. The Sandhills Lakes Region (~1,500 natural lakes — most spring-fed alkaline groundwater-supported lakes with self-sustaining largemouth populations) carries the state's most distinctive natural-lake largemouth tier.
