Talybont Reservoir

Talybont Reservoir — Talybont Reservoir, Powys, Brecon Beacons National Park

Talybont sits in a heavily wooded steep-sided Brecon Beacons valley — three hundred and eighteen acres of wilderness reservoir, wild brown trout only, fly only, and the kind of approach where the path through the conifers does the work of convincing you you're going somewhere proper.

How to fish it · for Trout
When
Late April–June; evening rises May–August
Where
Start with Diawl Bach (12-14) — on the bob / top dropper. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Diawl Bach (12-14) — on the bob / top dropper. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

Fish early and late, try deeper during the heat of the day with a fast-sinking line.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Either bank or boat

Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

About this water

Talybont sits in a heavily wooded steep-sided Brecon Beacons valley — three hundred and eighteen acres of wilderness reservoir, wild brown trout only, fly only, and the kind of approach where the path through the conifers does the work of convincing you you're going somewhere proper. The opening date is 20 March; the season runs to early October. Day tickets are catch-and-release on the Passport, capped at thirty rods, which on a water this size means you'll mostly hear birds. Buzzers from April, with the kind of evening rises that justify staying out past common sense.
