Bega

The Bega, also known as the Begej, is a 244-kilometer-long (152-mile) river that flows through Romania (169 km; 105 mi.) and Serbia (75 km; 47 mi). It originates in Romania's Poiana Ruscă Mountains, which are part of the Carpathian Mountains, and flows into the Tisa river near Titel, Vojvodina, Serbia. Its drainage basin spans 4,458 km2 (1,721 sq mi), with 2,362 km2 (912 sq mi) in Romania.

The Begej joins the large Danube–Tisa–Danube Canal (or DTD) near Klek and turns south, receiving water from the Stari Begej. It is then separated from the DTD route, which turns west and leads to Zrenjanin. From there, it heads south along the Tisa's old riverbed, passing through Ečka, Stajićevo, and Perlez. It flows through marshlands in this section, some of which are transformed into the Ečka fish pond, Serbia's largest with a 25 km2 area (10 sq. mi.). The remaining wetlands form Carska bara (11 km2; 414 sq. mi.), Serbia's largest swamp, after which the Begej empties into the Tisa.
