Not the day for it
River temperature is the limiting factor today, not the flow. This is not the day to push it. Check the thermal advice above before you head out.

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 23.1°C. This is the line where catch-and-release kills brown trout. Do not fish for them today.

About this water

The Tordera drains the Montseny massif and flows to the coast. Granite geology throughout creates typical freestone character. The southernmost Catalan salmonid zone, with marginal trout habitat reflecting lower elevation and Mediterranean influence.

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.
