Many fly anglers have heard the stories of double digit brown or rainbow trout that can be found all over the world, but few know about the massive cutthroat trout that have been caught throughout history. My second biggest ever trout of my life happens to be a Snake River Cutthroat I had the pleasure of landing in Jackson, Wyoming. These fish are aggressive and can grow to be massive!
The Biggest Cutthroat Trout in the World (According to IGFA)
According to the IGFA, the largest cutthroat trout ever caught was a 41-pound beast that was caught in 1925. Believe it or not, it was taken out of Pyramid Lake in Nevada! It was a Lahontan strain of the cutthroat. The Lahontan strain of cutthroat is generally the largest cutthroat trout you’re going to find.
A Little Bit About Cutthroat Trout
Cutthroat trout are native to cold-water areas on the West Coast of the United States, the Rocky Mountains and the Great Basin throughout the Midwest United States. Cutthroat are known for the red color under their gills. It almost looks as if the fish were cut under their gills and they’re bleeding; hence, the name cutthroat trout.
Cutthroat trout aren’t overly different in their habitat and feeding styles to the rest of the trout species. They need cold, highly oxygenated water with gravel bottoms and a healthy amount of insect life. Cutthroat trout populations have risen and fallen throughout the years, but recent efforts by state Game and Fish Departments and local chapters of trout anglers help sustain these populations and protect them at all costs.
How Old is a Cutthroat Trout
Trout generally live somewhere between five and ten years. While cutthroat trout aren’t the biggest of the trout species, they grow to be larger than brook trout but smaller than brown and rainbow trout.

Where Can I Find World Record Cutthroat Trout?
Pyramid Lake, Nevada- Home of the World Record
If you want a shot at the world record, you have to fish Pyramid Lake. Located around 30 miles north of Reno, it’s hard not to be surprised when you first stumble on it. It covers over 700 square miles and is upwards of 350 feet deep. It’s fed by the Truckee River and no water is able to escape! You can fly fish or spin fish for these trout, but if you’re fishing in the middle of the lake, stick with spin fishing.
The cutthroat trout can weigh five to ten pounds and measure in over 20 inches! With some effort, you can absolutely tie into a monster.
If you’re fly fishing, spend time fishing near where the Truckee River enters the lake. This provides good access to the fish. Large streamer patterns like the Clouser Minnow or Wooly Bugger are good options.
Snake River, Wyoming – Consistent Large and Healthy Populations
If you have a chance to target Cutthroat on the Snake River near Jackson, Wyoming, you have to do it. Running near Grand Teton National Park and further into the mountains, the Snake River provides anglers with miles of access to a fairly healthy population of fish. The Cutthroat is endangered all throughout Wyoming except for the population in the Snake River.
Snake River Cutthroat can be anywhere from 10 to 20 inches and weigh a couple of pounds.
A fly rod should be your top choice when targeting these fish! Use your 5-weight with floating line and a 3x leader and throw Caddis, Terrestrial, Stonefly and Mayfly representations. Traditional patterns like the Pheasant Tail Nymph and Chubby Chernobyl are perfect.

Omak Lake in Washington state is well-known for their high populations of healthy cutthroat trout. The Lahontan species of these fish swim through the waters of Omak Lake.

If you’re spin fishing, use a plug!
Fly fishing is generally successful with bright Clouser Minnows! If you’re using a fly rod, make sure you’re using a 6-weight or 7-weight fly rod, so you can make longer casts and fight any of those larger fish that you might find. You’ll want 0x or 1x leader and both floating and sink-tip fly line since you’ll be throwing heavy streamers.
Meadowdale Beach Park, Washington- Sea Run Cutthroat
Meadowdale Beach Park in the Puget Sound on the coast of Washington is a great place to find sea-run Cutthroat Trout. Sea-run Cutthroat are aggressive and can grow over 20 inches and several pounds.
