Following seven days of intensive fieldwork, an international team of over 70 scientists and students has officially concluded Una Science Week.

River protectors from across Europe are linking arms with the community of the Una Spring in Croatia this Friday to protest the construction of an illegal dam at the source of this unique river, “The One”. Join the protest!

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.
