Course

edit

The Sosva is formed at the confluence of the Big and Small Sosva in the eastern slopes of the Northern Urals. It flows across the West Siberian Lowlands. Finally it meets the right bank of the Tavda River 719 km from its mouth.

The Sosva freezes up in early November and breaks up in April. It is navigable within 333 kilometres (207 mi) of its estuary.[2]

Its main tributaries are the Vagran, the Turya, the Kakva, and the Lyalya.[1]
