With the length of 109 km (68 mi) it is the longest river that flows completely within the borders of Serbian province of Vojvodina.

The longest stream originates from Pavlovac hillock (Serbian Cyrillic: Павловац) northeast of Bajmok, one of the most populous villages in Vojvodina.

The river passes next to the villages of Mali Beograd and Zobnatica, a tourist resort and site of the famous stud-farm, before it reaches the town of Bačka Topola.

A 20 years-long survey by the Serbian Environmental Protection Agency, published in 2019, showed that rivers in Vojvodina are the most polluted in Serbia.

Additionally, the dam upstream holds more water for farm irrigation during summers than it should, so the river is turned into the slow open sewage canal.
