How to fish it · for brown trout
When
Through the open trout season. Spring olives April through May; sedges through summer evenings; small dark flies into autumn close.
Where
Pool tails and pocket water through the Haute-Loire valley. Massif Central freestone — clear cold water.
Method
Upstream dry to risers; dry-dropper through the riffles. The water reads clear — long leader, fine tippet. Move slowly, cast accurately.
Kit
9 ft #4 — French freestone default. Floating line, 12 ft leader to 4 to 5 lb fluoro. Studded boots.
Why this works
⛔ Water at 22.3°C. This is the line where catch-and-release kills brown trout. Do not fish for them today.

About this water

The upper Loire, before it becomes the sand-flat river of French school geography, is a proper mountain stream. It rises on the Gerbier de Jonc in the Ardèche volcanic highlands and spends its first hundred kilometres as freestone granite water — pools, riffles, stony runs, the occasional deep corner where a proper fish might be holding. This is Haute-Loire country, high and exposed, the kind of water where you can fish an afternoon without seeing another angler and sometimes without seeing another human. The trout are wild and small-to-medium, the grayling modest but steady, and the hatches honest rather than famous — good Baetis through spring, caddis building from May, stoneflies in the faster runs. The water runs cold until late May because the altitude keeps it that way, so the season starts slowly and doesn't really hit its stride until the hawthorns are out. Nymph it in April and May, dry-fly it from June onwards, and accept that you are fishing for the place as much as for the fish. Nobody comes to the upper Loire to empty the water. You come because it is remote and honest and the river remembers what it is for.

Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
