Cutthroat Trout (Oncorhynchus clarkii)
Where to Find Cutthroat Trout
This map shows global observations of cutthroat trout, highlighting the continents, countries, and water bodies where this species thrives.
Prime Fly Fishing Locations for Cutthroat Trout
Cutthroat trout, easily recognized by their distinctive red slash marks under the jaw, primarily inhabit the cold, clear freshwater streams and alpine lakes of the Western United States. These fish were left behind by receding glaciers during the last Ice Age, flourishing in the region’s free-flowing waters.
During their summer spawn, cutthroat trout display vibrant colors—ranging from olive to gold—with a striking fiery-red throat slash. They are most abundant in states like Montana, Wyoming, Colorado, Utah, and Idaho, though their range extends from California to New Mexico.
How to Fly Fish for Cutthroat Trout
A weight-forward floating line is ideal for targeting cutthroat trout. If the fish are feeding deeper, consider adding a sinking leader. Bring extra leader material, as rocky riverbeds can cause fraying or breakage.
Patience is key when pursuing cutthroat trout. Like their rainbow trout relatives, they can be selective feeders. Focus on deeper pools below fast-moving currents, where oxygen levels are high, or along the shallow edges of calm pools.
Best Flies for Cutthroat Trout
Cutthroat trout feed on insects, small fish, and crustaceans, so flies effective for other trout species work well here.
For dry flies, try the Elk Hair Caddis, CDC, Black Gnat, or Blue Winged Olive. Effective nymphs include the Buzzer, Pheasant Tail Nymph, and Hare’s Ear. If trout are chasing prey but not surface-feeding, small streamers like the Mickey Finn or Woolly Bugger are excellent choices.
