How to fish it · for trout
When
June–September
Where
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A

Set up a broadside drift and cover the water systematically. 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

Sedge should come on through the afternoon as the water warms.

Boat — drift

A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.
