The Upper Angara (Russian: Верхняя Ангара, Verkhnyaya Angara; Buryat: Дээдэ Ангар, Deede Angar) is a river in Buryatia, Siberia to the northeast of Lake Baikal. the third longest river in the Baikal basin. It is 438 kilometres (272 mi) long, and has a drainage basin of 21,400 square kilometres (8,300 sq mi).[1]
The Baikal–Amur Mainline runs along the north side of the river northeast up its valley, crossing between Anamakit and Novy Uoyan and crossing the river a second time upstream before heading into the mountains.[2]
Course[]
The Upper Angara rises at about 1,600 m (5,200 ft) in an area of small glacial lakes of the Delyun-Uran range, right by the Northern Muya Range, Stanovoy Highlands. It its upper course the river flows in a WSW direction across mountainous terrain, with rapids and waterfalls. It enters then a floodplain and crosses the spurs of the Upper Angara and the Barguzin ranges. Near Yanchukan it flows through the Upper Angara tectonic basin. Finally it ends in Lake Baikal forming a delta in the shallow northern end of the lake, separated from the deep part by long sandy spits, including . The Upper Angara is navigable in its last stretch.[3]
The main tributaries of the Upper Angara are the 64 km (40 mi) long Angarakan, the 87 km (54 mi) long , the 124 km (77 mi) long Churo and the 245 km (152 mi) long .[1]
