When
Morning into early afternoon.
Where
Pool tails, steadier runs, and any water with pace.
Method
Fish a sensible line-and-fly combination for the height and pace of water.
Kit
13 ft #8/9 double-hander in spate, 10 ft #8 single in low water. Floating line plus a fast-sink tip. 12–15 lb fluoro tippet.
Why this works
⛔ Water at 21.6°C. This is the line where catch-and-release kills atlantic salmon. Do not fish for them today.

The 3 beats
Bryn IthonDay tickets
Wye & Usk Foundation (Fishing Passport)
Left-bank-only stretch of the River Ithon, just under a mile, just downstream of Llandrindod Wells. Shale/bedrock bed, notably underfished.
Fishing Passport, max 2 tickets/day. Parking ~650m from beat start.
DisserthDay tickets
Wye & Usk Foundation (Fishing Passport)
~3 miles of River Ithon just downstream of Llandrindod Wells (mostly right bank, with a two-thirds-mile double-bank middle section). Non-exclusive — a local club also holds rights here, though overlap is described as remote given the length.
Fishing Passport, max 4 tickets/day.
Severn Arms — Beat 1Day tickets
Wye & Usk Foundation (Fishing Passport)
One of three beats making up the Severn Arms' 4 miles of River Ithon near Penybont — this is Beat 1. Easy, open, gravel-bed water, among the most accessible on the whole Wye catchment. Grayling and trout primarily; salmon spawning also occurs on this reach.
Fishing Passport, max 2 tickets/day. Parking ~150m. Accommodation tie-in with the Severn Arms Hotel. Grayling trotting start date here is 1 Oct — earlier than the 1 Nov used on Bryn Ithon and Disserth Ithon, so don't assume a catchment-wide date.
What's coming
Plan ahead
5-day outlook
Water here around 22°C. Nothing cooler within range — carry a thermometer.
