- Free fishing
- Fly only
Start with Black Buzzer (12–16) on a slow, natural presentation — check locally for the preferred method. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
If the main plan stalls, drop to a size 14–16 midge — switch to a washing-line or suspender rig and change drift line before you change food group.
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
