Where

The plan
Plan A

Start with Spent Gnat (12-14) on a As per local method. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

If surface work dries up, try a diawl bach or hare's ear on the point and skate a sedge pattern on the bob at last light.

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.
