How to fish it · for Trout
When
Late April–June; evening rises through summer
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

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.

About this water

The highest of the Ogwen Valley AA waters at six hundred and seventy-eight metres — a tiny Carneddau cwm lake, two hundred and fifty by a hundred and fifty metres, in the cwm beneath Pen yr Ole Wen and Carnedd Dafydd. Excellent wild brown trout to a pound on a water you can walk round in twenty minutes if you don't fish it. Traditional fly only, no bubble float. Forty-five to sixty minutes' walk in from the road.

  • Lake
  • Ordovician volcanics sediment
Why this score
  • Buzzer is in its seasonal window, boosting the chance of targeted feeding.
