Stillwater · Silurian Mudstone Shale · Wales / Vale of Clwyd, Denbighshire (Clwyd catchment)

Llyn Clywedog (Saron)

A calm forest-fringed reservoir under blue sky, with a weir structure crossing the water and pine-covered hills reflected on the surface.

This Clywedog has nothing to do with its famous namesake down in mid-Wales — no six-hundred-acre reservoir, no windsurfers, just a small, quiet water near Saron that the Vale of Clwyd Angling Club keeps going for its own members and their own pleasure.

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

This Clywedog has nothing to do with its famous namesake down in mid-Wales — no six-hundred-acre reservoir, no windsurfers, just a small, quiet water near Saron that the Vale of Clwyd Angling Club keeps going for its own members and their own pleasure. The lowland setting near Denbigh means gentler country than the club's Snowdonia neighbours further west, and the wild browns here fish accordingly — a little more coarse-water manners, a little less of the high-hill wariness. It's the kind of club fishery that never makes anyone's list of essential Welsh waters and doesn't much want to. Ask locally before you go; this is proper grassroots fishing, run by and for the people who use it.
