How to fish it · for brown trout
When
Late April–June; evening rises through summer
Where
Work Gold-ribbed Hare's Ear on the bob and Pheasant Tail Nymph on the point.

The plan
Plan A · Plan B · what to watch · bank or boat
The plan
Plan A
Work Gold-ribbed Hare's Ear on the bob and Pheasant Tail Nymph on the point.
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
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Boat — at anchor
Windy conditions suit anchoring in productive areas rather than open-water drifting.
