Severe drought restrictions (alerte renforcée) in force

The Moselle amont et Meurthe - eaux superficielles zone (Dept 54) is at alerte renforcée — 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°37223

Temporary notices from official orders and recent fishery reports — they clear automatically once out of date.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 Vologne rises on the crest of the Vosges and runs down through granite pine forest with the kind of self-contained quietness that makes you forget the rest of France exists. The upper valley is managed with more care than most — fly-only, barbless, no-kill on the designated beats — and it shows in the fish. Wild brown trout of the local Vosges strain, educated by generations of dry-fly pressure and fully capable of ignoring a size 14 that is anything less than perfectly presented. Match the baetis in spring, move to caddis in summer, and keep a small emerger pattern handy for the slow glides where the bigger fish sip. Solitude increases upstream. The further you walk, the more it feels like the river has been waiting for you. Not a river for the impatient — one for the patient with legs.

Hatches & food

In Vosges granite catchments, trout in cool freestone streams feed on early and spring olives once levels settle after winter, daytime stoneflies over clean, stony runs, a broad band of evening caddis supported by rich bug life in the region, steady small buzzer activity on mild days, and terrestrials strongest where the river is hemmed in by forest.

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