Jezero Jasna

Jezero Jasna — Lake Jasna (Kranjska Gora)

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.

Water temperature is the limiting factor today, not the wave. Fish dawn or dusk if you go at all, and handle everything with extra care.

How to fish it · for Trout
When
The daddy longlegs are on. Wind-blown Terrestrials 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. Keep a sedge-style dry or emerger on a short leader for the evening rise.
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. Keep a sedge-style dry or emerger on a short leader for the evening rise.

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

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Boat — drift

A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

About this water

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. Stocked, tourist-facing, and worth including honestly as exactly that rather than dressing it up as wild water.
