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.
