Pčinja (river)

The Pčinja originates from several streams on the western slopes of the Dukat mountain which meet at the village of Radovnica and continue to the west originally under the name of the Tripušnica (Cyrillic: Трипушница). The river creates a micro-region of Pčinja, with center being the municipal seat of Trgovište where Tripušnica meets the left tributary of Lesnička reka (Cyrillic: Лесничка река) from the south and continues to the west under the name of Pčinja. The region represents one of the fastest depopulating and economically least developed parts of Serbia (population of 12,556 in 1971 (34 per km²) and 6,372 in 2002 (17 per km²; down 50%). After the Pčinja passes next to the northern side of the mountain of Široka planina and the village of Šajince where it receives the right tributary of Koćurica (Cyrillic: Коћурица) from the north, it is prevented to continue to the west by the eastern side of the Rujen mountain and turns south, into the narrow valley between the Rujen and Kozjak mountains. The small village and monastery of Prohor Pčinjski are located in the valley. Just after the river passes next to the monastery, after 52 km of flow in Serbia, the Pčinja crosses the Macedonian border.

For the remaining 83 km, the river bends gently to the southwest. It passes next to the villages of Karlovce, Dragomance, Strnovac, Vojnik, Klečevce, Pčinja, Studena Bara, Gorno Konjare, Dolno Konjare and the small town of Katlanovo, with the neighboring Katlanovska Banja,[2] the most popular spa in North Macedonia. The upper course in North Macedonia creates a micro-region of Sredorek (Macedonian: Средорек), and the lower a micro-region of Kotorci (Macedonian: Которци), with the gorge of Bader (Macedonian: Бадерска клисура) in between. In the lower course, the Pčinja follows the western side of the mountain Gradištanska and flows into the Vardar river, on the gorge of Taor section of the Vardar's course, halfway between the cities of Skopje and Veles.

Katlanovo is located on the highway Skopje-Thessaloniki, and even though some 25 km away from Skopje, a string of Skopje's fast growing suburbs is located along the highway (Jurumleri, Idrizovo, Petrovec), and if the city continues to grow, in some future it will reach Katlanovo and the banks of Pčinja.

• The Pčinja belongs to the Aegean sea drainage basin. Its own drainage area covers 3.140 km², of that 1.247 km² in Serbia and 1.893 km² in North Macedonia.
• The average discharge on the river's mouth into the Vardar is 14 m³/s, and it is not navigable.
• All the major tributaries of the Pčinja are in North Macedonia: Bistrica, Petroshnica and Kriva Reka from the left; Kumanovska reka, from the right.
