Not the day for it
River high but settled. Not much stacked in your favour today. Worth an hour if you are nearby, not worth the special trip.

How to fish it · for Rainbow Trout

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.

Seasons & zones
  • Trout 1 March → 30 September
  • Grayling 16 May → 30 November

    Slovenian common default: grayling 16 May – 30 November (lipan). Slovenia is permit and fishing district controlled — dates may vary by specific water. Always check the Ribiška Družina (fishing district) permit for the specific beat. The Soča, Idrijca, and Sava system hold world-class grayling alongside marble trout.
