Körös-ér


The Körös-ér or Kereš, is a river in southern Hungary and northern Serbia, a 90 km long right tributary to the Tisa river. It flows entirely within the Bačka region of both Hungary and Serbia : 37 km in Hungary, 15 km as a border river and 29 km in Serbia.

Hungary

The Körös-ér springs in the Hungarian part of the Subotička Peščara, between the towns of Jánoshalma and Kiskunhalas. It flows to the southeast, more as a series of connected bogs and less as a real river, without almost any settlements on its banks. West of the village of Kelebia, the Körös-ér becomes a border river between Hungary and Serbia.

Serbia

The Körös-ér flows on the northern border of Subotica proper, close to its neighboring settlements and the Ludoš lake. After the villages of Male Pijace and Velebit, it turns east north of the village of Senćanski Trešnjevac and empties into the Tisa at Adorjan, at an altitude of. Near the village of Velebit, Kereš flows through the marshy area of Kapetanski Rit.
For some time the municipal government of Kanjiža protests about the extreme pollution of the Kereš's water, as it represents the single largest polluter of the Tisa river. Local politicians point at the city government of Subotica, which dumps its waste into the river, as the major culprit for such a bad condition of the river.
The river is neither channeled nor navigable. It is also called Kőrös or Kireš by the local population.

History

The first known source that presents the river, together with its portions drawn on map, dates back to 1694 from count Marsigli, who uses the Latinism "Kiris".
