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 21.4°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots. Otherwise very poor — water clarity is in the right range.

About this water

Boundary river between A Coruña and Lugo provinces, entering the sea near O Barqueiro. Dark-water, rain-driven salmonid catchment with wild character and clear salmon heritage, but current practical fishing is better framed around brown trout and sea trout because salmon are depleted and out of bounds.
