Bregalnica
The Bregalnica watershed as defined by the Bregalnica River Basin Management Project in 2013 comprises a territory of 4'307 km, which is approximately 21% of the Vardar watershed in 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.
