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 22.3°C. This is the line where catch-and-release kills brown trout. Do not fish for them today.

About this water

A classic Catalan-Aragonese Pyrenean river flowing southwest from high limestone plateaux. Limestone gorges alternate with alpine valleys throughout; clear, alkaline freestone holds brown trout with good size distribution in upper reaches. Technical runs, pools, and pocket water reward careful presentation. Karst geology means rapid spate response sustained by groundwater storage. Access from La Pobla de Segur (middle) or Espot (upper). Long fly-fishing tradition makes this a mature, rewarding destination.

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