The Angara is a major river in Siberia, which traces a course through Russia's Irkutsk Oblast and Krasnoyarsk Krai. It drains out of Lake Baikal and is the headwater tributary of the Yenisey. It is 1,849 kilometres (1,149 mi) long, and has a drainage basin of 1,039,000 square kilometres (401,000 sq mi). It was formerly known as the Lower or Nizhnyaya Angara. Below its junction with the Ilim, it was formerly known as the Upper Tunguska and, with the names reversed, as the Lower Tunguska.
The Yenisey is the fifth-longest river system in the world, and the largest to drain into the Arctic Ocean.
The Lena is a river in the Russian Far East and is the easternmost river of the three, great rivers of Siberia, including the River Ob and the River Yenisey, which flow into the Arctic Ocean. The Lena river is 4,294 km (2,668 mi) long and has a capacious drainage basin of 2,490,000 km2 (960,000 sq mi); thus the Lena is the eleventh-longest river in the world and the longest river entirely within Russia. Geographically, permafrost is the type of soil that underlies most of the Lena river's catchment, twenty per cent (20%) of which is continuous.
The Nizhnyaya Tunguska is a river in Siberia, Russia, that flows through the Irkutsk Oblast and the Krasnoyarsk Krai. The river is a right tributary of the Yenisey joining it at Turukhansk. The ice-free period on the Nizhnyaya Tunguska starts in mid-June and ends in the first half of October. The river forms the western limit of the Lena Plateau.
The Turukhan is a river in northern Krasnoyarsk Krai in Russia. It is a southeast-flowing left tributary of the Yenisey. The river is 639 kilometres (397 mi) long. The area of its basin is 35,800 square kilometres (13,800 sq mi). The Turukhan freezes up in October and stays under the ice until late May or the first half of June. Its main tributaries are the Usomchik, Bolshaya Bludnaya, Verkhnyaya Baikha and Nizhnyaya Baikha from the right and Makovskaya from the left. Its mouth is 20 kilometres (12 mi) downstream from Turukhansk, where the Lower Tunguska joins the Yenisei. The river is navigable for about 288 kilometres (179 mi) from its mouth to the settlement of Yanov Stan. It was part of the canoe route from the Gulf of Ob – Taz – Turukhan – Yenisey – Nizhnyaya Tunguska – Yakutsk. The uncompleted Salekhard–Igarka Railway from the Ob to the Yenisey was planned to cross the Turukhan at Yanov Stan.
The Belaya in its upper course Yurumkuveyem is a south-flowing tributary of the Anadyr in the Chukotka Autonomous Okrug administrative region of Russia.
The Yenisey Gulf is a large and long estuary through which the lower Yenisey flows into the Kara Sea.
The Great Yenisey is a river in the Republic of Tuva, the right source of the Yenisey, at its confluence with the Little Yenisey.
The Konda is a river in the Khanty–Mansia region of Russia. The town of Uray and the Shaimskoye oil field are along the Konda.
Siberian River Routes were the main ways of communication in Russian Siberia before the 1730s, when roads began to be built. The rivers were also of primary importance in the process of Russian conquest and exploration of vast Siberian territories eastwards. Since the three great Siberian rivers, the Ob, the Yenisey, and the Lena all flow into the Arctic Ocean, the aim was to find parts or branches of these rivers that flow approximately east-west and find short portages between them. Since Siberia is relatively flat, portages were usually short. Despite resistance from the Siberian tribes, Russian Cossacks were able to expand from the Urals to the Pacific in only 57 years (1582-1639). These river routes were crucial in the first years of the Siberian fur trade as the furs were easier to transport over water than land. The rivers connected the major fur gathering centers and provided for relatively quick transport between them.
