The Anabar (Russian: Анабар, romanized: Anabar, in its upper course: Большая Куонамка Bolshaya Kuonamka; Template:Lang-sah) is a river in Sakha, Russia, located between the rivers Khatanga and Olenyok. Its catchment extends into the Putoran Mountains that form the highest part of the Central Siberian Plateau. It is 939 kilometres (583 mi) long, and has a drainage basin of 100,000 square kilometres (39,000 sq mi).
Its mean annual discharge is approximately 500 cubic metres per second (18,000 cu ft/s), concentrated heavily in early summer when the ice that covers the river for most of the year thaws. The Gulf of Anabar is believed to be the easternmost fjord in Russia – defining the point at which the climate during the Last Glacial Maximum became too dry for glaciers to form. A clear transition from fjords to deltas at river mouths is apparent shortly to the east at the Lena River delta.
The basin of the Anabar river is notable as the location of the largest concentration of diamond deposits in the world outside of Africa and Australia. These deposits made the Soviet Union into one of the world's largest producers of diamonds, and remain the economic mainstay of the area.
History
Historically Evenks have inhabited the basin of the Anabar River. Vasiliy Sychev was the first Russian to reach the river in 1643.
