Llyn Rhosgoch

Llyn Rhosgoch venue image

Picturesque is the word the Aberystwyth AA uses for Rhosgoch and they're not wrong — five hectares of upland water, a short uphill walk from the road, wild brown trout trickle-stocked to a pound and a half.

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

Picturesque is the word the Aberystwyth AA uses for Rhosgoch and they're not wrong — five hectares of upland water, a short uphill walk from the road, wild brown trout trickle-stocked to a pound and a half. The best fishing comes when the Coch-y-Bonddu beetle is up in late June, or on a still sedge evening through July. Fly only.

  • Lake
  • Silurian mudstone shale
Why this score
  • Temperature (cool) is in the sweet spot for autumn fishing.
  • Buzzer is in its seasonal window, boosting the chance of targeted feeding.
