How to fish it · for Trout
When
The buzzer is on. Fry may also come into play as the day warms. The ripple is helpful — fish should move onto the feed and a slow-drifted team or single wet will cover water well.
Where
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
Plan B
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Watch for
Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.
Boat — drift
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

Trout fly box
Ultra-clear spring-fed rivers with large educated trout. Sight fishing, technical presentation, fine tippets. Euro-nymphing dominant subsurface method. Exceptional dry-fly windows during hatch periods. Gacka is the flagship water.

Jezero Jasna
A small artificial lake at the foot of the Julian Alps by Kranjska Gora — famous first as a postcard, with the bronze chamois statues on the rocks and the peaks stacked up behind it, and only second as a fishery.
