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.

The plan
Plan A
Set up a broadside drift and cover the water systematically. Work Pheasant Tail Nymph on the bob and Diawl Bach 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
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Boat — drift
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

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.
