The Vitim (ru|Витим; evn|Витым, ; sah|Виитим, ; Buryat and mn|Витим, Vitim) is a major tributary of the Lena. Its source is east of Lake Baikal, at the confluence of rivers Vitimkan from the west and China from the east. The Vitim flows first south, bends eastwards and then northward in the Vitim Plateau. Then it flows north through the Stanovoy Highlands and the town of Bodaybo.Including river Vitimkan, its western source, it is long, and has a drainage basin of .[1]
It is navigable from the Lena to Bodaybo. Upstream, tugs can haul barges as far as the Baikal Amur Mainline (BAM), but this is becoming rare.
The Vitim is an excellent place for adventure rafting, but is rarely visited because of its isolation. Baissa, one of the famous localities of fossil insects is situated on the left bank of the Vitim River.
The first Russian to explore the river was probably Maksim Perfilyev in 1639–40, who brought back reports of the upper Amur River.[2] Formerly, because of its swift current, goods were hauled 144km (89miles) overland from Chita to Romanovka. There boats were built, floated down the river, and broken up at their destination. This lasted until the late 1940s.
The Vitim event occurred in the Vitim River basin near Bodaybo on 25 September 2002. The event was probably caused by a bolide. The event was similar to Tagish Lake.
Going upstream: Vitim town where the Vitim joins the Lena. Mama and Mama Airport, about 130km (80miles) south of Vitim. A muscovite mica mine from 1705 until the late 1930s. Now a small settlement. Mamakan, on a west-flowing stretch 200km (100miles) south-southeast of Vitim. In 1963 a 86MW dam on the Mamakan River was completed, one of the first dams built on permafrost.[3] Bodaybo, just upstream, a gold mining center founded in 1864. Upstream, the port of Luzhki was the start of a road to the Lena gold fields. From here upstream the river goes crookedly east and then south. About 240km (150miles) upstream from Bodaybo are the Delyun-Uran Rapids[4] and after 140km (90miles) more, the Parama Rapids. About 40km (30miles) or so upstream, the Vitim is crossed by the Baikal Amur Mainline between Taksimo and Kuanda. Upriver there are more rapids and goldfields. South through the Stanovoy Mountains toward Chita, then west into the Vitim Plateau east of Lake Baikal.[5] The river peaks in June and freezes from November to May.
The main tributaries of the Vitim are, from source to mouth:[1]
