2026 regulation year

New Hampshire Brown trout 2026 — Season, Bag Limit, Size Rules

Salmo trutta

Last updated June 3, 2026

Brown trout thrive in New Hampshire's larger, warmer rivers where brook trout fade — the Connecticut River (the NH/VT boundary, where the NH state-record brown trout 16 lb 6 oz / 32.50 in was caught at Pittsburg in 1975 by Ken Reed Jr.), the Androscoggin tailwater (Errol to Berlin, one of New England's premier wild brown trout tailwaters on cold releases from Umbagog Lake via Errol Dam), and the Pemigewasset, Saco, Lamprey, and Contoocook all hold wild + stocked browns. NHF&G stocks browns as part of the 350,000+ annual catchable-trout program (New Hampton + Berlin + Powder Mill + Milford hatcheries); the larger rivers grow holdover browns to trophy size. Browns were among the introduced salmonids that displaced the native Sunapee Trout in the early 20th century. Standard regs: a combined trout daily limit of 5 fish OR 5 pounds (whichever is reached first, across brook + brown + rainbow), no minimum length, open January 1 – October 15 on rivers + streams and the open-water season on lakes + ponds; on the designated salmon lakes the combined trout + salmon limit drops to 4 fish (no more than 2 salmon). The Connecticut Lakes 'Trophy Stretch' + Trophy Trout Ponds run year-round artificial-lures-only catch-and-release. NH does NOT issue a separate Trout Stamp.
