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

Conach sits in the hill country above Talybont, one of a handful of small lakes the local association looks after quietly and without much fuss. It's fly-only water, wild brown trout only, no stocking truck ever troubling the access track. The ticket system is refreshingly analogue — you buy your day permit at the garage or the pub in the village, the way half of upland Wales still runs. Nothing about Conach demands attention: no signature hatch, no reputation beyond the valley. Just a walk-in lake holding fish that have never seen a hatchery, and a season that runs the standard April-to-September window. Go for the quiet as much as the fishing.
