When the Reški Creek sinkhole was dammed in the 1970s, Lake Kočevska Reka was created, which measures about 20 ha in size. Recently, the upper part of the lake was protected as a forest reserve, where interventions are not allowed, while the lower part is intended for boat fishing and other types of recreation.
Around the lake is the Eagle's Path, which with information boards and didactic aids offers visitors an insight into many interesting facts from the life of the white-tailed eagle, which nests in the vicinity of Lake Kočevska Reka.
Unique flora and fauna have formed in the lake and its surroundings in recent decades. Lake Kočevska Reka is exclusively a district for hunting predators and is rich in pike and skis, and their hunting is only allowed from a boat. In addition to them, carp, grass carp, perch, sickle, chub, redfin, tench, perch, toothless mussels and alder crabs can be found in the lake.
