The Frunziș (also: Leveleș) is a right tributary of the river Teuz in Romania. It flows into the Teuz near Tămașda. Its length is 35km (22miles) and its basin size is 153km2. The construction of the canalized lower course of the Beliu in 1914-19 disconnected it from its upper course, which now discharges into the Beliu near Berechiu.[1] [2]
