How to fish it · for Trout
When
Cloudy or lightly breezy days, cool to moderate water; spring and autumn the steadiest, with buzzer activity through the warmer months.
Where
Start with Coch-y-Bonddu Beetle (10-14) — on the bob / top dropper. As evening approaches, switch to dries or emergers if you see surface activity.
The plan
Plan A

Start with Coch-y-Bonddu Beetle (10-14) — on the bob / top dropper. As evening approaches, switch to dries or emergers if you see surface activity.

Plan B

Fish early and late, try deeper during the heat of the day with a fast-sinking line.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Bank

Bank fishing near inflows, dam walls, and weed beds. Move to find feeding fish.
