Llyn Eiddew Bach

A grey, still upland lake bordered by tussocky moorland grass and a low rocky outcrop, under an overcast sky.

Eiddew Bach is the smaller of two llyns strung along the hills above Talsarnau, a modest wild-brown water that doesn't get much attention next to its bigger neighbours.

How to fish it · for Trout
When
May–August; evening rise in settled weather
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

Eiddew Bach is the smaller of two llyns strung along the hills above Talsarnau, a modest wild-brown water that doesn't get much attention next to its bigger neighbours. There's no stocking here — what you catch is what the lake has grown itself, which usually means modest sizes but honest fish, willing enough on a warm evening when the wind lies down. It's a walk-in water, no boat, no fuss, the kind of place that rewards showing up rather than researching. Bring a small box of wets and don't expect company. The Ardudwy hills keep their llyns quiet, and Eiddew Bach is quieter than most.
