Dordogne (upper)

A rocky, boulder-strewn mountain stream flowing through autumn woodland on the upper Dordogne near La Bourboule, France.

The upper Dordogne flows from Puy-de-Dôme mountains through classic Massif Central terrain — granite and volcanic rock creating cold, clear freestone.

Severe drought restrictions (crise) in force

The zone Dordogne des grands barrages rive droite (19) zone (Dept 19) is at crise — the second-highest French drought tier — under a préfectoral arrêté. Fishing itself is not named as prohibited, but water is severely restricted and flows are likely very low; fish with care and check locally.

Arrêté préfectoral n°37328 ↗

Temporary notices from official orders and recent fishery reports — they clear automatically once out of date. Always confirm locally before travelling.

Slow going — pick your moments
River temperature is the limiting factor today, not the flow. Fish dawn or dusk if you go at all, and handle everything with extra care.

How to fish it · for Brown Trout
When
Through the open trout season. Spring olives April through May; sedges through summer evenings.
Where
Pool tails and pocket water through the upper Dordogne valley above the dams. Auvergne freestone.
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 18°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots.

About this water

The upper Dordogne flows from Puy-de-Dôme mountains through classic Massif Central terrain — granite and volcanic rock creating cold, clear freestone. Wild brown trout and grayling. Strong mayfly, caddis, and stonefly populations. Designated no-kill parcours on some sections. Upper reaches more technical, lower more accessible. Check local regulations for restrictions.

Hatches & food

In freestone rivers of the Massif Central, resident brown trout feed through a spring build-up of olives and stoneflies into a long summer of caddis and small buzzers, with terrestrials becoming important from early summer; higher volcanic plateaux and colder headwaters tend to run later than the lower freestones.
