Llyn Dwfn

Llyn Dwfn seen across open moorland, a small lake ringed by conifer plantation in the Cambrian Mountains above Talybont.

Dwfn means deep, and whoever named it wasn't exaggerating for effect — this is a smaller lake with more water underneath it than its modest surface lets on, tucked into the same stretch of hill above Talybont as its neighbours.

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

Dwfn means deep, and whoever named it wasn't exaggerating for effect — this is a smaller lake with more water underneath it than its modest surface lets on, tucked into the same stretch of hill above Talybont as its neighbours. Talybont AA's day ticket, bought at the garage or pub down in the village, covers it along with the rest of their upland water, April through September. Fly only, wild brown trout only, and enough solitude that you'll likely have the bank to yourself. It's not a lake that announces itself. You fish it because it's there, because the walk up is honest work, and because the trout owe nothing to a stocking van.

Why this score
