Llyn Coch Hwyad

A dark blue upland lake bordered by golden reeds and heather moorland in the foreground, with a line of conifer forestry along the opposite shore under a clear sky.

Coch Hwyad sits up in the hills above Llanbrynmair, on ground the small local association has fished quietly for generations without much need to advertise the fact.

How to fish it · for Trout
When
Late April–June; evening rises through summer
Where
With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. Calm evenings are perfect for individual dry fly work — target rising fish. Keep a sedge-style dry or emerger on a short leader for the evening rise.
The plan
Plan A

With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. Calm evenings are perfect for individual dry fly work — target rising fish. 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

Sedge should come on through the afternoon as the water warms.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

About this water

Coch Hwyad sits up in the hills above Llanbrynmair, on ground the small local association has fished quietly for generations without much need to advertise the fact. Wild brown trout, upper Twymyn water, the kind of lake that barely registers outside the immediate valley and doesn't seem to mind. There's no boat, no stocking programme, no ticket booth with a laminated price list — just a club that knows its own water and members who'd probably rather you didn't make too much noise about it. If you can find someone to point you at it, and get permission sorted, it's an honest hill lake doing exactly what it's always done.
