Severe drought restrictions (crise) in force

VigiEau lists this venue's surface-water zone (3. Secteur Aude amont (hors axe réalimenté), dépt 11) at crise, under an official préfectoral drought arrêté. Fishing is not itself banned by it, but water levels are low — go gently on stressed fish.

Ranked for today
Brown Trout fly box

More balanced than the mountain-river pack. French nymphing still matters, but there is more room for dries, spiders and general searching flies.

About this water

The upper Aude at Axat tumbles through limestone gorge where fishing is secondary to the sheer drama of the place. Designated no-kill, fly-only, barbless stretch. Wild brown trout. Technical pocket-water fishing in clear flows. Spring through early autumn offers consistent opportunity. Modest gradient makes wading workable. Permits required; check Aude prefectural regulations.

Hatches & food

No emergence timing has been documented for the upper river, but OFB monitoring at Escouloubre and Axat confirms a diverse stonefly, caddis and mayfly fauna (including Perla, Isoperla, Rhyacophila, Sericostoma and Ephemerella) — direct evidence of a rich food base at these specific stations, not a calendar for the whole upper Aude.
