Llyn Teifi

Wide view of Llyn Teifi, an upland reservoir lake in the Cambrian Mountains, Wales, with grassy moorland hills surrounding the water and a dam visible in the background.

Teifi is the one with the pedigree — the actual source lake of the river that carries its name all the way down through Tregaron, Lampeter and Cardigan to the sea, which gives an otherwise unassuming upland pool a certain quiet significance.

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. Keep a sedge-style dry or emerger on a short leader for the evening rise.
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. Keep a sedge-style dry or emerger on a short leader for the evening rise.

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.

About this water

Teifi is the one with the pedigree — the actual source lake of the river that carries its name all the way down through Tregaron, Lampeter and Cardigan to the sea, which gives an otherwise unassuming upland pool a certain quiet significance. The trout are wild browns, much like the rest of the pools group, unremarkable in size but entirely of the place. There's something worth pausing over in standing at the literal beginning of a river you might fish forty miles downstream the following week — few lakes let you close that particular loop. Fish it as part of the Teifi Pools circuit, and take a moment before you start casting.

Why this score
