Korana River

The Korana is a river that flows through central Croatia and west Bosnia and Herzegovina. The river is 138.6 km (86.1 mi) long and has a catchment area of 2,301.5 km2 (888.6 sq mi). It is the ninth longest river in Croatia. The name of the river is derived from the Proto-Indo-European *karr- 'rock.'

Korana rises in the east of Lika, forming the Plitvice Lakes, a UNESCO World Heritage Site. The Korana river, which flows downstream from the Plitvice Lakes, creates a 25-kilometer-long border between Croatia and Bosnia and Herzegovina near Cazin. It then runs north into Croatia, until reaching the river Kupa at Karlovac.

The karst region through which this river travels has limestone soil. The river is continually producing new soil from plants under certain physical and chemical conditions. The Korana has a diverse molluscan assemblage of 33 species.
