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

Micropterus dolomieu

Last updated May 26, 2026

New Hampshire's smallmouth fishery centers on the six self-sustaining lake trout lakes (Winnipesaukee + Big Squam + Sunapee + Newfound + Winnisquam + Ossipee — all hold strong smallmouth populations on rocky shoreline structure) plus the Connecticut River main stem (NH/VT boundary water with VT licence reciprocal) and the smaller central + south-central NH lake tier (Lake Massabesic, Lake Winnipesaukee western coves, Bow Lake, Pleasant Lake). Lake Sunapee runs a NH-distinctive TROPHY MANAGEMENT rule on smallmouth — 16-inch minimum + 2 / day (one of the highest minimums in the Northeast). NH's standard rule is a 12-inch statewide minimum + 2-fish combined daily aggregate across largemouth + smallmouth — one of the lowest bag limits in the country, reflecting NH's deliberate quality-management approach. The Connecticut River main stem runs the same 12 in min + 2 / day combined under both NH and VT (matched rules via the NH/VT reciprocity statute).
