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 22.2°C. This is the line where catch-and-release kills brown trout. Do not fish for them today.

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.

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