Drin (river)

The Drin (; or ; ) is a river in Southern and Southeastern Europe with two distributaries one discharging into the Adriatic Sea and the other one into the Buna River. Its catchment area extends across Albania, Kosovo, Greece, Montenegro and North Macedonia. The river and its tributaries form the Gulf of Drin, an ocean basin that encompasses the northern Albanian Adriatic Sea Coast.
At long, the Drin is the longest river of Albania of which passes across Albania and the remainder through Kosovo and North Macedonia. It starts at the confluence of its two headwaters, namely the Black Drin and White Drin. It originates in the mountainous northern mountain range, flows westwards through the Albanian Alps and Dukagjin Highlands, and eventually drains into the Adriatic Sea, between Shëngjin and Durrës. Numerous lakes and reservoirs are formed by the river or flow into it such as the Fierza Lake and Koman Lake.
Located in the Balkan Peninsula at the crossroad of Europe and Asia, the river basin's varied climate and topography have shaped a vast array of flora and fauna. In addition, it has been recognised as one of the most important biodiversity hotspots in Europe. The Drin Delta is classified as an Important Bird Area of international importance by designation under the BirdLife International Convention.
Overview.
The Drin originates near the town of Kukës, in the northeast of Albania, at the confluence of the rivers Black Drin and White Drin. It then flows west for about passing through the Albanian Alps and Fierzë then upon reaching the Dukagjini highlands, flowing then to the south through Apripë e Gurit, Toplanë, Dushman, Koman, Vjerdhë Mazrrek, Rragam, and Pale Lalej. At Vau i Dejës, it enters the low Shkodër Field and splits into two arms. One empties into the Gulf of Drin into the Adriatic Sea southwest of Lezhë, forming the Mouth of Drin, ). The other empties into the Bojana River near the Rozafa Castle.
Measured from the source of White Drin, the rivers length is , making it the longest river in Albania. The Black Drin flows out from the Lake Ohrid near Struga and flow through eastern Albania and western North Macedonia. The White Drin originates from the Zhleb mountain, north of the town of Peja in the Dukagjin region of Kosovo, and flows from there through to Albania. 
The basin encompasses the transboundary subbasins of Lake Shkodër (largest lake in Southern Europe), Lake Ohrid (one of the most ancient lakes in the World), Lake Prespa and Small Prespa Lake and also the tributaries, namely Black Drin, White Drin and Buna River. All these subbasins and tributaries are home to numerous species of mammals, vascular plants, insects, amphibians, fish and birds.
The Drin is extremely important for the Albanian economy, especially for its electrical production. Four hydropower facilities produce most of Albania's electricity (over 1200MW capacity). The artificial Lake Fierza (Albanian: "Liqeni i Fierzës") created by the dam at Fierzë is the largest artificial lake in Albania with its surface of 73 km². The second largest artificial lake is also built on this river. Vau i Dejës lake () has an area of 25 km². Construction of the Fierza power station caused some controversy in the 1980s. Without reaching any agreement, the Albanian government ordered the reservoir to be filled with water, which flooded some border areas of Kosovo, then part of Yugoslavia. The Yugoslav government protested, but no solution was agreed on. Thus, today, Lake Fierza is shared by Albania and Kosovo.
Human history.
The ancient name of the river was "Drilon"; its lower valley was inhabited by the Illyrian tribe of the Enchele, whose territory spread through the Black Drin up to the source at Ohrid.
