Slow going — pick your moments
River temperature is the limiting factor today, not the flow. Fish dawn or dusk if you go at all, and handle everything with extra care.

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 18.2°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots. Otherwise poor — water clarity is in the right range.

About this water

A Verdugo tributary draining the Serra do Suído to the Ría de Vigo at Soutomaior. The Oitavén is honest small-river trout water — granite freestone bedrock, pool-riffle structure, partial canopy. Wild brown trout only. Best fished from May into early July in the middle reaches around Fornelos de Montes; useful as a follow-on river when the Verdugo is busy.
