How to fish it · for Trout
When
The daddy longlegs are on. Buzzer may also come into play as the day warms. The breeze will be blowing terrestrial insects onto the water — check the wind lanes and downwind margins for rising fish.
Where
Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A

Work a bushy searching pattern on the bob and drop a contrasting 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

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Bank

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