2026 regulation year

New Hampshire Largemouth bass 2026 — Season, Bag Limit, Size Rules

Micropterus nigricans

Last updated May 26, 2026

New Hampshire's largemouth fishery is dominated by Lake Winnipesaukee (NH's largest at 71 sq mi) + the central NH lake tier (Big Squam + Newfound + Winnisquam + Ossipee + Lake Massabesic + Bow Lake + Pleasant Lake) + the warm-water south-central NH ponds. Largemouth populations are concentrated in shallow weedy coves and bays rather than the deep clear basins where lake trout dominate. The Connecticut River main stem (NH/VT boundary) holds limestone-rich slack-water largemouth in the river backwater + impoundment pools (Wilder + Bellows Falls + Vernon + Moore/Comerford reservoirs — all under NH/VT reciprocity). NH's standard rule: 12-inch statewide minimum + 2-fish combined daily aggregate across largemouth + smallmouth — one of the lowest bag limits in the country, reflecting NHF&G's deliberate quality-management approach.
