How to fish it · for Trout
When
Late April to June and September
Where
Start with Marabou Damsel (8-12) — on the point. Early in the day, nymphs and buzzers fished slowly tend to outperform attractors.
The plan
Plan A

Start with Marabou Damsel (8-12) — on the point. Early in the day, nymphs and buzzers fished slowly tend to outperform attractors.

Plan B

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.

Watch for

Watch for Sedge towards evening — this could be the best window of the day.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
