New Hampshire supports SIX known self-sustaining lake trout lakes — Lake Winnipesaukee (71 sq mi, NH's largest), Big Squam (6,791 acres), Lake Sunapee (4,085 acres), Newfound Lake (4,106 acres, one of New England's cleanest deep-water lakes), Winnisquam Lake (4,264 acres), and 1st Connecticut Lake (2,807 acres in Pittsburg, NH's northern headwaters) — one of the highest concentrations of self-sustaining lake trout on the Atlantic seaboard south of Maine (MA Quabbin + Wachusett, NJ Round Valley + Merrill Creek, NH's six, ME's many). Lake Winnipesaukee fish reach 8-12 lb routinely with 15+ lb fish reported annually. Lake Sunapee + Newfound run NHF&G TROPHY MANAGEMENT rules — 24-inch minimum + 1 / day (versus the standard 18 in min + 2 / day on Winnipesaukee + Big Squam + Winnisquam + Ossipee + 1st Connecticut). NH-distinctive: Lake Sunapee was the type-locality of the Sunapee Trout (Salvelinus alpinus oquassa subspecies — a glacial-relict Arctic charr) which was driven to functional extinction in NH by introduced rainbow + brown trout competition in the early 20th century (the last verified Sunapee Trout caught from the lake was in the 1950s; reintroduction attempts from descendant stocks in Maine and elsewhere have failed). Lake trout season is open from ice-out (typically April 1) through end of October; January ice-fishing season open on listed waters.
