Lake Trout Stocking: Where America's Biggest Trout Get Planted

New York plants more lake trout than every other state in this dataset combined — 769 stockings across 59 waters since 2011 — almost all of it tied to a decades-long effort to restore the species to Lake Ontario and the Finger Lakes. Utah runs a far smaller program, concentrated at one high-elevation lake.

Key takeaways

• New York accounts for 769 of the roughly 1,090 lake trout stockings in this dataset — more than every other tracked state combined — spread across 59 waters including Lake Ontario and four Finger Lakes.
• Utah's lake trout program is far smaller (209 records, 30 waters) but concentrated at Fish Lake in Sevier County, home to a 17 lb., 11 oz. state-record lake trout caught in 1991.
• Montana and Washington both stocked lake trout historically — Montana's most recent recorded stocking was in 1992, Washington's in 2000 — with nothing recorded in either state since.
• Lake trout are chars, not true trout, and need much colder, deeper water than rainbow or brown trout — one reason this program is so much narrower than most other stocked species on this site.
• New York's program exists because sea lampreys, an invasive parasite, wiped out Lake Ontario's native lake trout by the 1950s; stocking has continued for decades as part of a joint U.S.–Canadian restoration effort.

Why Lake Trout Aren't Just Another Stocked Trout

Despite the name, a lake trout (Salvelinus namaycush) isn't a true trout at all — it's a char, in the same genus as brook trout and Arctic char, rather than the genus that covers rainbow, brown, and cutthroat trout. That distinction matters for stocking: lake trout need deep, cold, well-oxygenated water year-round, which is why they're planted into only a handful of waters in this dataset instead of the hundreds that get rainbow trout.

They're also slow — slow to grow and slow to mature, but capable of living for decades once established. A lake trout fishery that collapses doesn't bounce back in a season or two the way a put-and-take rainbow trout pond does; it can take a generation of fish, and often a generation of stocking, to recover.

New York's Great Lakes Recovery Program

New York's lake trout program traces back to an invasive species. Sea lampreys, native to the Atlantic Ocean, reached Lake Ontario through the Erie Canal as early as 1825, then spread into the upper Great Lakes after the Welland Canal was improved in the early 1900s. Lamprey populations exploded in the late 1940s, and by the 1950s they — combined with decades of commercial overfishing — had wiped out Lake Ontario's native lake trout entirely.

Restocking attempts between 1953 and 1964 mostly failed; lampreys kept killing stocked fish faster than they could establish. It wasn't until 1980, when U.S. and Canadian agencies began formally coordinating a restoration plan — completed in 1983 — alongside improved lampricide treatment of tributary streams, that the recovery effort still running today really took hold. U.S. Fish & Wildlife Service reporting on the program describes it as one of the longest-running fisheries restoration efforts in the country.

That history shows up directly in the data: Lake Ontario alone accounts for 611 recorded lake trout stockings, and the program extends into four Finger Lakes — Canandaigua, Hemlock, Seneca, and Cayuga — all naturally deep, cold lakes suited to a species that most New York waters simply can't support.

Utah's High-Desert Outlier: Fish Lake

Utah's lake trout program looks nothing like New York's. Instead of a multi-lake restoration effort, it's concentrated almost entirely at one water: Fish Lake, in Sevier County, which accounts for 75 of Utah's 209 recorded lake trout stockings. Fish Lake is Utah's largest natural high-elevation lake, sitting at roughly 8,800 feet in the Fishlake National Forest — cold and deep enough, unlike most of the state's reservoirs, to hold lake trout (known locally as Mackinaw) alongside splake and rainbow trout.

The lake has produced Utah's benchmark fish for the species: a 17 lb., 11 oz. lake trout, 45 inches long, caught by Travis T. Jenson in 1991 — still the state record more than three decades later.

Where Lake Trout Stocking Has Stopped

Montana (94 records, 18 waters) and Washington (15 records, 8 waters) both show real lake trout stocking history in this dataset — Montana's dating back to 1940, Washington's to 1995 — but neither has a recorded stocking since 1992 and 2000, respectively. The source data doesn't tell us why a given program stopped, and we won't guess.

What we can say is that a stocking program ending doesn't automatically mean a fishery failed. In the Great Lakes, Lake Superior's lake trout stocking program ended in 2015 for the opposite reason — natural reproduction had recovered enough that hatchery fish were no longer needed.
