Bodgynydd sits above the Conwy Valley on Llanrwst Anglers' patch, close enough to Bychan and Goddionduon to share the same hills and the same weather, though it's a different club altogether that looks after it.

How to fish it · for rainbow
When
The damsel nymph is on. Buzzers may also come into play as the day warms. The ripple is helpful — fish should move onto the feed and a slow-drifted team or single wet will cover water well.
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

Watch for Sedge towards evening — this could be the best window of the day.

Boat — drift

A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

About this water

Bodgynydd sits above the Conwy Valley on Llanrwst Anglers' patch, close enough to Bychan and Goddionduon to share the same hills and the same weather, though it's a different club altogether that looks after it. Wild browns are the backbone of the fishing, dark little fish that have made their own living here, and the club supplements them with stocked rainbows to keep the sport ticking along for members who want something more certain to show for an evening out. It's a working club lake rather than a showpiece — no boat, a walk to reach it, and a membership roll of people who know exactly where the fish sit and aren't in any hurry to tell you.

Why this score
  • Wind conditions (ripple) closely match what this water fishes best in.
  • High temperatures may push fish deeper and reduce surface activity.
  • Damsel Nymph is in its seasonal window, boosting the chance of targeted feeding.
