The Dibër Valley (definite Albanian form: Dibra; Macedonian: Дебар, Debar; Turkish: Debre) is a section of the Drin valley in the border region between North Macedonia and Albania. The high-altitude valley is surrounded by even higher mountains on all sides: to the north is the Korab range, containing Mount Korab which, at 2764 metres, is the highest point in both countries; the mountains on the other sides also exceed 2000 metres. The Black Drin flows from the south through a narrow canyon into the valley and leaves it through a similarly steep canyon. Previously the river was notorious for annual floods, as a result of which there are no settlements near the river itself. Since the construction of a reservoir on the Macedonian side, the Debar Lake, the level of the river is regulated.
