Why Target Rainbow Trout?
Rainbow trout may lack the striking appearance of brown trout, but they also don’t share their finicky nature. Unlike brown trout, rainbows remain active even when conditions aren’t perfect, putting up a fierce fight when hooked. Their rapid growth, adaptability, and willingness to bite make them a favorite among fly fishers and fishery owners.
Behavior and Habitat
Rainbow and brown trout share some traits. Both feed at all depths, from the surface to the riverbed, and in rivers, they often hide behind boulders, darting out to ambush prey carried by the current. Like brown trout, rainbows grow more predatory with age.
However, rainbows are less solitary, often moving in groups. If you hook one, others are likely nearby. They also tolerate a wider range of temperatures, making them more active in summer when brown trout retreat to cooler depths.
Fly Fishing Techniques for Rainbow Trout
-
Locating the Fish
- In stillwaters, focus near dams, where rainbows often corner schools of small fish late in the season.
- In warm weather, they gather near overhanging trees where insects fall into the water. They also forage along shorelines in summer and autumn.
-
Dry Fly Fishing
- Requires patience, as rainbows may take up to 10 minutes to strike.
- In open water, they often swim just below the surface in calm "wind lanes," targeting insects blown across the water.
-
Fishing in Rivers
- If not surface feeding, target deeper areas with weighted flies, especially near boulders where they shelter.
- Try deep pools below cascades, where aerated water attracts fish.
- Don’t overlook faster, shallower stretches—rainbows are more resilient than brown trout and may strike in surprisingly shallow water.
-
Stealth Matters
- Wear muted colors and position yourself against vegetation to avoid spooking the fish.
Best Flies for Rainbow Trout
- Stillwaters: Use a Black Buzzer or nymphs like the Hare’s Ear and Pheasant Tail Nymph. Count down to determine the depth where fish are active.
- Streamers: Effective options include the Mickey Finn or Muddler Minnow. Experiment with retrieval speeds—slower retrieves work better in winter when fish conserve energy.
- Dry Flies: Carry a variety (e.g., White Wulff, Hare’s Ear Emerger, Quill Gordon) to match surface insects. Wait for the trout to fully take the fly before striking.
- Low-Light Tactics: As dusk falls, try a large wet fly like a March Brown, casting across and downstream to let the current do the work.
With these strategies, you’ll be well-equipped to land these spirited and adaptable fish. Happy fishing!
