Bregalnica

Bregalnica (, ) is the second largest river in North Macedonia. It starts as a spring near the mountain city of Pehchevo and it passes through Berovo, Delchevo, near the cities of Makedonska Kamenica, Kočani, Vinica and Štip, before joining the river Vardar on its way to the Aegean Sea. Recent issues have concentrated around the pollution of the river, as many of the factories located in the cities through which it passes used it as a dumping ground for waste waters, which is further aggravated with the pesticide-treated waters of the extensive rice fields near the city of Kočani. It was the place of Battle of Bregalnica.

==The Bregalnica watershed== The Bregalnica watershed as defined by the Bregalnica River Basin Management Project in 2013 comprises a territory of 4'307 km2, which is approximately 21% of the Vardar watershed in North Macedonia and about 17% of the overall territory of the country. The Bregalnica watershed borders with Bulgaria in the east, Strumica River catchment in the south, Pcunja River in the north, and Vardar River in the west. The average altitude of the Bregalnica watershed is 722 m a.s.l. The Bregalnica river catchment encompasses the territory of the whole East Planning Region. This includes the municipalities of Berovo, Češinovo-Obleševo, Delčevo, Karbinci, Makedonska Kamenica, Kočani, Pehčevo, Probištip, Štip, Vinica and Zrnovci. It also includes almost the complete territories of Lozovo and Sveti Nikole municipalities (Vardar Region), of Konče Municipality (South-Eastern Region), and a significant portion of the territory of the Kratovo Municipality (25%). Even though the Bregalnica catchment boundary mainly coincides with the municipal boundaries, minor parts of the territory of Radoviš, Negotino, Gradsko, Veles, Kumanovo and Kriva Palanka fall into it as well.
