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

Corsica's south-coast mountain river — steep, short, cold, carrying endemic trout genetics. Technical pocket-water fishing in plunge pools and cascades. Small dry flies and precise nymphing. Conservation priority for native Corsican lineage. Clear, oxygenated water year-round. Strong regulatory backing for no-kill. Spring through early summer best.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
The dawn and dusk windows score higher than the midday lull.
