The spring fly box selection for Creston and the wider Kootenays, running from ice-out in April through late June. With rivers swollen and muddied by spring runoff, stillwater fishing on local lakes is the main game.
Stillwater Chironomid & Leech Dominance
During spring, rising water temperatures trigger massive chironomid hatches in the region's lakes. Anglers should focus on vertical, slow presentations over shoals and drop-offs.
•
Chromie / Chironomids (#12–16): The silver holographic body mimics the trapped gas bubble of midges emerging to the surface. Fish them suspended statically under an indicator 1–2 feet off the bottom bc flyfishing youtube library 2026 07.
•
Bloodworm (Cranberry Larvae) (#10–14): Fished directly along the mud bottom. Highly productive in early spring before pupae hatches begin in earnest.
•
Balanced Leech (#8–12): Phil Rowley's signature horizontal pattern suspended under an indicator to ride wave action. Tying it in black, olive, or "Bruised" (black/purple) is a top producer bc flyfishing youtube library 2026 07.
•
UV Pregnant Shrimp (Scud) (#12–16): Fished on a floating line under an indicator or stripped slowly on an intermediate sinking line tight to the reeds.
Early-Season River Nymphing
Before rivers blow out with peak runoff, or just as the June 15 opening day arrives:
•
Pat's Rubber Legs (#6–10): Crawford stoneflies migrate to riverbanks to crawl out and hatch. Drift this heavy nymph tight to structure and seam lines.
•
Gold-Ribbed Hare's Ear (#12–16): Suggestive of early mayfly nymphs and scuds moving in the current.
