Severe drought restrictions (crise) in force

The Charente amont - Bandiat zone (Dept 24) 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°37650

Temporary notices from official orders and recent fishery reports — they clear automatically once out of date.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 Bandiat is a minor Dronne tributary, a quiet limestone stream running through the oak woods and water-meadows of the Nontron country in northern Dordogne. It is small enough to ignore on a map, significant enough to hold wild brown trout in reasonable numbers, and obscure enough that reliable English-language information about it barely exists. This is the sort of river where you find out about the good beats by knowing someone who knows someone at the local AAPPMA, and where the best day you have ever had on a small stream is not impossible. The Bandiat is limestone-fed like the rest of the Dronne system — stable flows, clear water, strong summer weed, and wild trout that behave accordingly. Hatches are dominated by small olives, caddis, and terrestrials in the warmer months. Fish it short, stay low, and treat it as a stalking river rather than a prospecting one. The middle reaches around Nontron and Javerlhac are the most productive water. The groundwater buffering keeps the river in condition for most of the season, though it does warm through July and August when the flow drops and the surface weed takes over.

Hatches & food

In chalk-spring and karst trout systems, generally stable temperatures broaden olive and other mayfly activity from early spring into autumn, with strong evening caddis, steady subsurface scuds and buzzers where clear groundwater and weedbeds develop, and terrestrials from meadow and woodland banks rounding out the food calendar, depending on how fast each river drops and clears after rain.
