Vitim River
 Vitim River (Russian and Buryat: Витим Vitim; Evenki: Витым Witym; Sakha: Виитим Viitim [local pronunciation]) is a major tributary of the Lena River. With its source east of Lake Baikal the Vitim flows 1978 km north through the Transbaikal Mountains and the town of Bodaybo. The river peaks in June and freezes from November to May. It is navigable from the Lena to Bodaybo. Upstream tugs can haul barges as far as the BAM but this is becoming rare.
