How to fish it · for Trout
When
May–September; mayfly peak late May–June
Where
Set up a broadside drift and cover the water systematically. Work Bibio on the bob and Murrough on the point.
The plan
Plan A
Set up a broadside drift and cover the water systematically. Work Bibio on the bob and Murrough 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.
Bank
Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.
