The hydrographical network

The depression zone of Caransebes is watered by the river Timis with his tributary steams.
The Timis River, the biggest river in Banat (with a total length of 339.7 km, from which 241.2 km are on the Romanian territory), flows from the eastern versants of the Semenic Mountains, which unify with the Semenic, Gradiste and Brebu brooks and form the lake known as “Trei Ape” (Three Waters). The Timis River begins from here.
The Timis River is the primary hydrographical artery, which collects the waters from the space between the Cerna Mountains, Tarcu, Muntele Mic and the Poiana Rusca Mountains. Its first affluent is Raul Rece, which comes from Tarcu, in the Teregova zone. From here the course of the river Timis changes its direction, orienting itself from South to North. To Armenis, it receives as affluent Raul Lung and Raul Alb, both from the Tarcu zone. Going out of Armenis Keys, two rivers flow in the Timis, on the left side, Slatina and Goletul; these rivers have got the names of the villages they cross.
In Caransebes, on the right side, the Timis receives the Sebes River, which collects all the waters from the Muntele Mic sector.
Near Jupa (Tibiscum), into Timis flows the biggest affluent from the area, the Bistra River, formed of Bistra Mare and Bistra Marului, which unite at Otelu Rosu. These rivers collect the waters from the Godeanu Mountains.
At Caransebes, because of the reduced slope, the river has large meanders. In the Sacu zone, the Timis River enters in the Timis County. It flows into the Danube River on the Serbian territory.
The Sebes River springs from the South of Muntele Mic, it crosses through Borlova and Turnu-Ruieni and flows into the Timis River. Until Borlova it has the shape of a brook with fast waters and with a deep and small valley and from here the slope gets smaller and the valley is gradually widened.
Ieruga, which flowed through the centre of the town, is a deflection of the Sebes River, which is canalized today; there were some mills on it, which explains the name of Canalul Morilor (Channel of Mills).
The Potoc is a brook which crosses through the north-east part of the city and in the summer it becomes crossable by foot, because it has a small volume of water.
This brook formerly supplied the Caransebes fortress with water. Its name comes from Latin, poto - potare, because in a chronicle from the Neamt Monastery, there was written “hic rivus nominatur Potocus” referring to the river which supplied the settlement.
