Lake Ribnica is an artificial lake, built in 1971 due to the construction of a dam on the Crni Rzav, the Black Rzav, one of the arms of the Rzav in Zlatibor ; the dam provides food and drinking water for the towns of Kralje Vode (Zlatibor) and Čajetina. The lake is abundant in fish, particularly gudgeon, trout, tench and silurus.
