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 18.5°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots. Otherwise poor — river flow is in the right range.

About this water

Corsica's second-longest river flowing from high mountains to the east coast. Mountain torrent character with endemic trout in technical pocket water. Steep, cascading sections with plunge pools. Small dry flies and nymphs effective. Spate character — best during or shortly after rainfall. Check local regulations.
