Introduction to Cutthroat Trout

Cutthroat trout (Oncorhynchus clarkii), named for their distinctive red slash marks beneath the jaw, are a prized catch for fly anglers. These striking fish thrive in the cold, clear waters of the Western United States, particularly in states like Montana, Wyoming, Colorado, Utah, and Idaho. Their vibrant colors—ranging from olive to gold—intensify during the summer spawn, making them a visually stunning target.


Where to Find Cutthroat Trout

Cutthroat trout are native to the freshwater streams and alpine lakes of North America, with their distribution shaped by glacial retreats during the last Ice Age. While they are most abundant in the Western U.S., populations also extend into parts of Canada and even introduced regions worldwide.

Prime Locations Include:

  • High-elevation streams and rivers
  • Alpine lakes with cold, oxygen-rich water
  • Rocky, fast-flowing sections and calm pool edges

Essential Fly Fishing Techniques

Successfully targeting cutthroat trout requires the right gear and strategy.

Recommended Gear:

  • Fly Line: Weight-forward floating line (adjust with sinking leaders for deeper feeding fish)
  • Leader Material: Extra spools are advisable due to rocky riverbeds that can cause abrasion.

Tactics for Success:

  1. Observe Feeding Patterns: Cutthroat can be selective, so watch for surface activity or subsurface strikes.
  2. Target Oxygen-Rich Zones: Focus on deep pools below fast-moving currents or shallow edges of calm pools.
  3. Stay Patient: Like rainbow trout, cutthroat may require persistence and varied presentations.

Best Flies for Cutthroat Trout

Cutthroat trout feed on insects, small fish, and crustaceans, making a diverse fly selection key.

Top Fly Choices:

  • Dry Flies: Elk Hair Caddis, CDC, Black Gnat, Blue Winged Olive
  • Nymphs: Pheasant Tail, Hare’s Ear, Buzzer
