Albania has an extensive hydrographic network of 152 rivers and streams, including 10 large rivers flowing from southeast to northwest, mainly discharging towards the Adriatic Sea. Combined, they produce a total annual flow rate of 1,308 cubic metres per second (46,200 cu ft/s).
In the mountainous regions, the rivers meander through narrow valleys with steep banks and great depth, collecting streams and silt during heavy rains. Their beds become erosive, causing frequent changes in their paths.
The Drin (/driːn/; Albanian pronunciation: [dɾin], Albanian definite form: Drini, pronounced [ˈdɾini]) or Drim (Serbian and Macedonian: Дрим, pronounced [drim]), is a river in Southeastern Europe with two major tributaries – the White Drin and the Black Drin and two distributaries – one discharging into the Adriatic Sea, in the Gulf of Drin and the other into the Buna River. Its catchment area extends across Albania, Kosovo, Serbia, Greece, Montenegro and North Macedonia and is home to more than 1.6 million people. The river and its tributaries form the Gulf of Drin, an ocean basin that encompasses the northern Albanian Adriatic Sea Coast.
At 285 kilometres (177 miles) long, the Drin is the longest river of Albania and its tributaries cross through both Kosovo and North Macedonia. Its northern tributary, the White Drin starts from the foothills of Žljeb, at White Drin Waterfall in west Kosovo, and flows generally south, whereas its southern tributary, the Black Drin originates from Ohrid lake in the town of Struga, North Macedonia and flows north. Both tributaries' confluence occurs near Kukës in northeast Albania and Drin then flows westwards through the Albanian Alps and Dukagjin Highlands, where three successive dams were erected between 1960s and late 1980s, forming 3 large artificial lakes. The Drin then passes Vau i Dejës and drains into the Adriatic Sea through its two distributaries in Buna river and west of Lezhë.
