The Birekte (Russian: Биректе; Yakut: Билэктэ, Bilekte) is a river in Yakutia (Sakha Republic), Russia. It is a tributary of the Olenyok with a length of 315 kilometres (196 mi). Its drainage basin area is 8,600 square kilometres (3,300 sq mi).[1]

The river flows north of the Arctic Circle, across a lonely, desolate area devoid of settlements.[2]

Course

The Birekte is a left tributary of the Olenyok. Its sources are in the northern fringes of the Central Siberian Plateau. It heads first southwards and, after the confluence of the Omonos, it flows roughly northeastwards. Finally it joins the left bank of the Olenyok river 13 km (8.1 mi) downstream from the confluence of the Ukukit, 669 km (416 mi) upstream of its mouth.[3][2]

The river is fed by rain and snow. It is frozen between early October and late May. The longest tributary is the 140 kilometres (87 mi) long Omonos (Омоноос) from the right.[1][4]

Birekte Terrane

The Birekte terrane is located by the Anabar Shield, in the north-eastern part of the Siberian Craton, in the basins of the Popigay, Anabar, Birekte and Olenyok rivers. It is defined entirely from geophysical data and is overlain by Riphean-Paleozoic platformal cover.[5][6][7][8][9][10]
