Massachusetts Trout (rainbow + brown + brook) 2026 — Season, Bag Limit, Size Rules

Oncorhynchus mykiss / Salmo trutta / Salvelinus fontinalis

Last updated May 26, 2026

Massachusetts runs one of New England's largest stocking programs through MassWildlife's five state hatcheries (McLaughlin in Belchertown + Roger Reed + Sunderland + Sandwich + Bitzer in Montague) — over 500,000 catchable-size rainbow + brown + brook trout + tiger trout stocked annually across designated stocked streams + ponds. The Swift River below Winsor Dam at Quabbin Reservoir is one of New England's premier coldwater wild brown trout tailwaters with a catch-and-release fly-fishing-only special-regulation reach. The Deerfield River below Fife Brook Dam (Florida MA) is the major western-MA tailwater + whitewater destination supporting wild + stocked rainbow + brown trout — Pulpit Rock and the upper Wild + Native sections are catch-and-release artificial-only. The Westfield River system (main + east + west branches) is a Wild + Scenic federally-designated river with wild brook + brown trout headwaters. Quabbin Reservoir + Wachusett Reservoir both support self-sustaining lake trout populations + stocked rainbow + brown trout + landlocked Atlantic salmon (Quabbin only). Squannacook + Nissitissit + Nashua tributaries hold wild brook trout + heavily-stocked sections in north-central MA. MA does NOT issue a separate Trout Stamp — the standard freshwater licence covers trout fishing statewide.
