New Mexico Lake trout 2026 — Season, Bag Limit, Size Rules
Salvelinus namaycush
Last updated
New Mexico lake trout (Salvelinus namaycush — also called mackinaw or laker) is an introduced deep-cold-water char, stocked by NMDGF in the 1970s–1980s into the state's deepest, coldest high-elevation reservoirs, where it shares the cold hypolimnion with kokanee salmon (its primary forage). Heron Reservoir (5,900-acre Willow Creek reservoir near Tierra Amarilla — Rio Arriba County — Bureau of Reclamation San Juan-Chama Project) is NM's premier lake trout fishery — NM state-record lake trout 31 lb 6 oz Heron Reservoir 1999 (Paul Casias) — alongside El Vado Reservoir + Eagle Nest Lake + Navajo Reservoir + Abiquiu Reservoir. Lake trout are long-lived, slow-growing apex predators that hold deep (60–120 ft) through summer and are taken by deep trolling (lead-core / downriggers + large spoons + tube jigs) or vertical jigging; in the cold months they move shallower. Because lakers grow slowly and a trophy fish may be 20–30 years old, NMDGF holds the bag at a conservative 2 / day with 4 in possession statewide — far tighter than the kokanee bag on the same reservoirs — to protect the slow-recovery trophy fishery. Open year-round.
