Water temperature for Brown Trout
Warm — slow22°C est.ideal 10–16°C

How to fish it · for Brown Trout
When
Through the Italian trout season — strong glacial-melt influence makes the Noce run cold and clear. Afternoon hatches in spring; dawn and dusk in summer warm.
Where
Pool tails and the deeper edges of pockets through Val di Sole. The Noce runs hard pocket water in its upper reaches; the middle river holds longer pools.
Method
Upstream nymph through the broken water; dry to risers in the glides. Italian No-Kill stretches mandate single barbless — comply or fish elsewhere.
Kit
9 to 10 ft #4 for medium freestone with Alpine clarity. Floating line, 12 ft leader to 4 to 5 lb fluoro. Studded boots — Alpine cobble runs slick.
Why this works
Water at 22.2°C. This is the line where catch-and-release kills brown trout. Do not fish for them today.

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.

Val di Non / Noce grayling (temolo): some zones open from the last Sunday of February, others later; most close end of October. Fly-only on NK1/NK2 zones. Grayling season structure varies by zona. Check with local Trentino association and visitrentino.info for current zone-level rules. Noce is part of the wider Trentino grayling destination — zone permits are essential.
Rules are set at province or association level — check locally.
