Severe drought restrictions (alerte renforcée) in force

The Cèze amont (de source à la confluence Tave jusqu'à la confluence avec la Claysse, ruisseau de la Clays) zone (Dept 30) 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°37649

Temporary notices from official orders and recent fishery reports — they clear automatically once out of date.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 23.5°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 Cèze rises on the southern flank of Mont Lozère and runs south-east through the Gard schist until it finally gives up and joins the Rhône below Bagnols. For most of its length it is exactly the kind of river you hope to find in this part of France and then discover is still largely ignored — dark schist pools, fast shallow runs, wild brown trout holding under the oaks, and the whole thing framed by the quiet Cévennes that tourists mostly drive past to get to the Pont du Gard. Fish it early in the season or write the summer off. The Cévennes gets proper Mediterranean weather — the rain arrives in biblical quantities in autumn and then almost nothing for three months — so by late June the middle Cèze is often a string of pools joined by dry gravel. The productive window is March to early June, before the heat takes hold. Standard Cévennes kit: a short rod, fine tippet, and a handful of hawthorn and Baetis dries for the honest hatches that arrive when everything lines up. After the first September rains the trout wake up again and October can be as good as May.

Hatches & food

In Cévennes and other Mediterranean-season trout rivers, spring olives and stoneflies dominate while flows are cool and comfortable for fish, followed by a relatively short but intense caddis spell as the rivers warm; terrestrials and small buzzers can offer chances around morning and evening once dangerous heat and skinny water ease off, with a further autumn reset of olives, small caddis and buzzers after the first good cooling rains.
