How to fish it · for Trout
When
June–September
Where
With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. Calm evenings are perfect for individual dry fly work — target rising fish. Keep a sedge-style dry or emerger on a short leader for the evening rise.
The plan
Plan A
With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. Calm evenings are perfect for individual dry fly work — target rising fish. Keep a sedge-style dry or emerger on a short leader for the evening rise.
Plan B
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Watch for
Damsel Nymph may strengthen through the middle of the day as conditions warm.
Bank
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
