The Lena is a river in the Russian Far East, and is the easternmost of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Ob and the Yenisey). The Lena is the eleventh-longest river in the world, and the longest river entirely within Russia, with a length of 4,294 km (2,668 mi) and a drainage basin of 2,490,000 kmยฒ (960,000 sq mi). Permafrost underlies most of the catchment, 77% of which is continuous.
Originating at an elevation of 1,640 meters (5,381 ft) at its source in the Baikal Mountains south of the Central Siberian Plateau, 7 kilometres (4 mi) west of Lake Baikal, the Lena flows northeast across the Lena-Angara Plateau, being joined by the Kirenga, Vitim and Olyokma. From Yakutsk, it enters the Central Yakutian Lowland and flows north until joined by its right-hand tributary the Aldan and its most important left-hand tributary, the Vilyuy. After that, it bends westward and northward, flowing between the Kharaulakh Range, part of the Verkhoyansk Range, in the east and the Chekanovsky Ridge in the west. Making its way nearly due north it expands into a large delta and ends in the Laptev Sea, a division of the Arctic Ocean, south-west of the New Siberian Islands. The Lena Delta is 30,000 square kilometres (12,000 sq mi) in area, being traversed by seven main branches, the most important being the Bykovsky channel, the farthest east.
The area of the Lena river basin is calculated at 2,490,000 square kilometres (960,000 sq mi) and the mean annual discharge is 489 cubic kilometers per year. Gold is washed out of the sands of the Vitim and the Olyokma, and mammoth tusks have been dug out of the delta. There are numerous lakes in the floodplain of the river. Lakes Nedzheli and Ulakhan-Kyuel are the largest in the basin of the Lena.
The Kirenga flows north between the upper Lena River and Lake Baikal. The Vitim drains the area northeast of Lake Baikal. The Olyokma flows north. The Amga makes a long curve southeast and parallel to the Lena and flows into the Aldan. The Aldan also curves roughly parallel to the Lena until it turns east and flows into the Lena north of Yakutsk. The Maya, a tributary of the Aldan, drains an area almost to the Sea of Okhotsk. The T-shaped Chona-Vilyuy system drains most of the area to the west.
