Massachusetts Smallmouth bass 2026 — Season, Bag Limit, Size Rules
Micropterus dolomieu
Last updated
Massachusetts's smallmouth fishery is the strongest in southern New England — Quabbin Reservoir + Wachusett Reservoir + the Connecticut River (Hatfield through Northfield + Turners Falls Pool) + the Merrimack River + the Berkshire reservoir tier (Pontoosuc + Onota + Otis + Cheshire) carry the trophy population. Quabbin (24,500 acres) is the unquestioned MA smallmouth flagship — the closed-watershed unfiltered Boston water supply has produced 6+ lb smallmouth on annual basis; the MA state-record smallmouth (8 lb 2 oz from Wachusett Reservoir, 1991) was caught from MA's other closed-watershed reservoir. The Connecticut River mainstem at Hatfield + Sunderland + Turners Falls + Northfield carries the western-MA river smallmouth tier with trophy fish in the 4 – 5 lb class. The Merrimack River north of Lowell carries the north-coast river smallmouth. MA's rule: 12-inch statewide minimum + 5-fish daily aggregate across largemouth + smallmouth — no closed season. Bass tournaments are common at Quabbin Reservoir (boat-permit-only) + Connecticut River + Pontoosuc Lake.
