- Fly only
Start with Cormorant (10-12) — on the bob / top dropper. If that does not produce, switch depth or speed before changing the pattern entirely.

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
