TheDunajec (Polish pronunciation:[duˈnajɛt͡s]; Goral dialects:Dónajec;Slovak pronunciation:[ˈdunajet͡s]) is ariver running through northeasternSlovakia and southernPoland. It is also regarded as the main river of the Goral Lands. It is a righttributary of theVistula River. It begins inNowy Targ at the junction of two short mountain rivers,Czarny Dunajec andBiały Dunajec (Black and White Dunajec). Dunajec forms the border between Poland andSlovakia for 17 kilometres (11 mi)[1] in thePieniny Środkowe (Slovak: Centrálne Pieniny)range, east of theCzorsztynreservoir.
The Dunajec is 249 kilometres (155 mi) long, including its source riverCzarny Dunajec,[1] which makes it Poland's thirteenth longest river. It has abasin area of 6,796 square kilometres (2,624 sq mi) (4,838 [1,868] in Poland, and 1,958 [756] in Slovakia).[1] On the Slovak-Polish border, the Dunajec flows through theZamagurie region, with attractions such as theDunajec River Gorge, theTrzy Koronymassif with a 500 metres (1,600 ft)precipice,Červený Kláštor, and twoPieniny castles inCzorsztyn andNiedzica.
Below the two source streams, the Dunajec flows through a broad valley called Nowotarska Basin. It then supplies the waters of the dam inNiedzica (Jezioro Czorsztyńskie Lake) and the dam inSromowce Wyżne (Sromowce Wyżne reservoir). Flowing through the central part of thePieniny range, it creates a picturesque turn at the Polish Slovak border betweenSromowce Wyżne andSzczawnica, where it flows byKotuńka rock which differentiates the area from the over parts of the river. Further down, it turns to the north into the WesternBeskid Mountains, and Sądecka Basin (where it merges with its own largest tributary, the Poprad river). It flows across an open valley of the Beskid Foothills and falls down acrossRożnów Foothills (with two more dams: the Jezioro Rożnowskie Lake, and Jezioro Czchowskie Lake) and finally, it leads into theSandomierz Basin and the valley of Vistula Lowlands. The Dunajec flows into theVistula River in the vicinity ofOpatowiec.
