In mid-spring, when the water is clear, rainbow trout in small streams bite best when your patterns look like the real thing and your drift is flawless. Here’s a practical, go-to guide you can take to the stream:
-
Fly sizes to bring
- Dry flies: sizes 16–20 (with a few 14–16 for early hatch days). In ultra-clear water you’ll often do better with the smaller end of this range.
- Nymphs: sizes 14–18 are the workhorse range for subsurface fishing.
- Midges (tiny patterns): sizes 18–22 for fussy, finicky fish in the breeze-free pockets.
- Tip: carry a few slightly heavier nymphs in 12–14 if you find deeper runs or slow, silted pools where fish aren’t moving much.
-
Patterns that reliably work in clear water
- Dry flies (matches for spring hatches):
- Baetis/Blue Wing Olive dries in 16–18.
- Pale Morning Dun (PMD) dries in 14–18.
- Adams and parachute patterns in 12–18 for broad mayfly looks.
- Pro tip: keep a small selection of gray, olive, and tan dries so you can match subtle color shifts in the water.
- See an intro to spring dry-fly tactics here: Spring Dry Fly Fishing For Brown Trout.
- Nymphs (best for when the fish aren’t aggressively rising):
- Pheasant Tail Nymph (14–18) for a classic mayfly/lake mayfly profile.
- Hare’s Ear Nymph (14–18) as a generalist, natural-bodied nymph.
- Prince Nymph (12–16) a reliable deeper nymph with good natural colors.

- Emergers and small patterns: small single- and staggered-drift emergers in olive/gray can trigger takers as hatches wind down.
- A versatile option you’ll see in pattern videos: Rainbow Yummy, a small articulated pattern that can work well in tight streams when trout are chasing small baitfish or courting insects. See the pattern video here: Rainbow Yummy - Fly pattern for Trout and Bass.

Presentation and gear tips
- Gear: a light 3–5 wt rod with a 9 ft, 4x–5x leader for dries; switch to 4x–6x tippet for nymphs and emerger patterns.
- Drift: aim for a perfectly straight, drag-free drift. Mend upstream to remove drag, and shorten your casts in tight pockets so the fly lands upstream and drifts naturally toward likely holding water.
- Stealth: keep a low profile and move slowly; in clear water, even small shadows can spook fish.
- Catch timing: mid-spring hatches (Baetis and PMD) bring the best windows; if you’re not seeing risers, switch to a slow, deep nymph cadence and dead-drift your pattern along seams and undercut banks.

Quick shopping list to support this setup
- A Prince Nymph selection is a solid starter (great for deeper runs). See: Flies Direct BH Prince Nymph Assortment Trout Fishing Flies.
- For dry patterns, a Lake & Stream Trout Fly ASST is handy to cover bases: Lake & Stream Trout Fly ASST 10-Pack.

With these sizes and patterns, you’ll maximize your odds in clear spring streams. Stay patient, keep your drifts clean, and enjoy the anticipation as those risers finally inhale your fly. Tight lines and happy spring fishing! 🐟🌿
