Creuse (Upper Combraille Reach)

Creuse (Upper Combraille Reach) — Rivarennes (Indre)

The upper Creuse, before the big reservoirs at Éguzon turn the lower river into something else entirely, is one of the quiet Massif Central trout rivers that rewards patience.

Severe drought restrictions (crise) in force

The Creuse amont zone (Dept 23) 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°37523

Temporary notices from official orders and recent fishery reports — they clear automatically once out of date.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

How to fish it · for Brown Trout
When
Nymphing can work through most of the day.
Where
Cover mixed depths.
Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
Water at 23.3°C. This is the line where catch-and-release kills brown trout. Do not fish for them today.

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 Creuse, before the big reservoirs at Éguzon turn the lower river into something else entirely, is one of the quiet Massif Central trout rivers that rewards patience. It rises on the Plateau de Millevaches — high, cold granite country — and runs through the Combraille in a series of stony runs and deep pools cut into the bedrock. The water is clear enough to see the bottom in most reaches, cold enough to keep the trout in condition well into summer, and unremarkable enough that very few people come to fish it. The trout are wild and small-to-medium. Nothing about the upper Creuse is designed to impress. It is honest water. Fish the nymph through April and early May while the plateau is still cold, switch to dry fly once the caddis arrive in the third week of May, and try to hit the river in June before the water drops too far. The Baetis hatches are reliable, the caddis predictable, and the stoneflies in the rough water worth fishing imitatively. There is very little access information available in English, and most of what exists is out of date. This is a river you come to slowly and learn by fishing. Most of the good beats are small and obscure.
