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

Poor — water clarity is working for you, but river flow is the limiting factor today.

What would change the calculation

Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.

Seasons & zones

Trout Dritter Sunday im May → 15 August
The Ponga is a headwater tributary of the Sella, rising in Ponga Natural Park well above the Sella's salmon-zone refuge limit, so it sits in the mountain-zone tributary network. Mountain-zone trout (zona de alta montaña): opens Third Sunday of May, not the general 15 March, minimum size 17cm (vs. 19cm general). Asturian regulation classifies any tributary joining above a salmon river's designated zone-limit point as alta montaña water. Inferred here from confluence position, not a verified lookup against the official cotos map (pescafluvial.asturias.es) — confirm before treating as final.
