Slow going — pick your moments
River temperature is the limiting factor today, not the flow. Fish dawn or dusk if you go at all, and handle everything with extra care.

About this water

Western Dunajec branch flowing from the Western Tatras, brown trout and grayling in spate-character water that responds quickly to mountain rain. Good caddis and stonefly hatches. The stream's dual personality—wild in flood, clear and selective in low water—makes it technically engaging.
