How to fish it · for Trout
When
April–June and September–October
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.
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.
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
Buzzer may strengthen through the middle of the day as conditions warm.
Bank
Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.
