The Bârsa (in its upper course also: Bârsa Groșetului, German: Burzen) is a left tributary of the river Olt in Romania. It discharges into the Olt near Feldioara.[1] Its source is in the Făgăraș Mountains. As several tributaries also have the name Bârsa, in order to differentiate them, the main course of the river is frequently referred to as Bârsa Mare. The river Ghimbășel, formerly a direct tributary of the Olt, was redirected towards the Bârsa. Its length is 73km (45miles) and its basin size is 937km2.
