Like many others of Europe’s last free-flowing rivers in the Balkan region, the Una is in permanent danger of being destroyed by a series of hydro dams. It is one of the few last rivers in the world with a healthy, wild Hucho population and an amazing fishery. For Bosnian guide Anes Halkic, the Una is not just a river. It is his life. In “Una – The One”, Jonas Borinski of Brothers on The Fly follow him in his fight against dams while searching for Hucho on the fly with Austrian guides Christof Menz and Uwe Rieder.
