Krupa (Lahinja)

The Krupa is a 2.5 km (1.6 mi) river in White Carniola, southeastern Slovenia. Its source is a karst spring in the village of Krupa below a rock wall. The bed has canyon characteristics in some places. At Gradac, the river joins the Lahinja from the left side. Its drop from the source to the outflow is only 6 metres (20 ft).

The river is protected as a natural monument and has been included in the Natura 2000 ecological network. It is the main feature of the Karst nature trail from Lebica to Krupa (Slovene: Kraška učna pot od Lebice do Krupe). Its source lake is the only habitat of the cave mollusk Congeria kusceri in Slovenia. It is also home to some cave snails and the olm.

The Krupa River is infamous because of its extremely high pollution with PCBs due to improper handling of PCB waste material which has been used for decades by the capacitor manufacturing company Iskra kondenzatorji in nearby Semič.

Lahinja

The Lahinja is a river in White Carniola, the extreme southeastern part of Slovenia. It is 34 kilometres (21 mi) long and originates from several karst springs at the end of a steephead valley between the villages of Knežina, Belčji Vrh, and Mali Nerajec.

In its upper course the river flows towards the north in a narrow bed with a very shallow gradient, resulting in the fact that it meanders significantly. All of its major affluents join it from the west and all of them start from karst springs. At Dragatuš it is joined by its major tributary Podturnščica Creek, and at Črnomelj by Dobličica Creek. From the outflow of Podturnščica Creek the bed of the Lahinja is narrow and up to 20 m deep, with numerous bends. At the vicinity of one of them stands Gradac Castle. From Črnomelj to Gradac the river has no surface affluents, but below Gradac it is joined by the high-volume and faster-flowing Krupa. After its confluence with the Krupa, the Lahinja turns towards the east. It joins the Kolpa at Primostek.
