Llyn Rhosgoch terrain map

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

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.

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.

  • Silurian mudstone shale
Why this score
  • Wind conditions (ripple) closely match what this water fishes best in.
  • Daddy Longlegs are in their seasonal window, boosting the chance of targeted feeding.
