How to fish it · for Rainbow 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
Good — water temperature is working for you, but time of day is the limiting factor today.

Poljanska Sora
One of the two Sora headwaters, managed jointly by RD Žiri, RD Visoko and RD Sora, and the more huchen-dominated of the pair according to its own managing clubs — the lower sectors run sulec in numbers that make this a genuine winter destination, not a footnote to the trout season.
