About this water

Sister stream to the Bistra, separately permitted, and carrying the same karst-spring character: brown trout, grayling, rainbow, pike, with huchen present. RD Vrhnika again the managing club. Small water, worth pairing with the Bistra on the same trip since both are five minutes apart and neither takes long to fish properly.
