Vychegda

The Vychegda (Russian: Вычегда; Komi: Эжва, romanized: Ežva) is a river in the European part of Russia, a tributary of the Northern Dvina. Its length is about 1,100 kilometres (680 mi). Its source is approximately 310 kilometres (190 mi) west of the northern Ural Mountains. It flows roughly in a western direction, through the Komi Republic and Arkhangelsk Oblast. The largest city along the Vychegda is Syktyvkar, the capital of the Komi Republic. The Viled, the Yarenga, and the Vym are among its main tributaries. The Vychegda flows into the Northern Dvina in Kotlas (Arkhangelsk Oblast). The river basin of the Vychegda comprises vast areas in Arkhangelsk Oblast and in the Komi Republic, as well as less extended areas in Kirov Oblast and Perm Krai. About 800 kilometres (500 mi) of the Vychegda is navigable. In 1822 the Vychegda was connected to the river Kama, a tributary of the river Volga, by the Northern Catherine Canal, which, however, has been disused since 1838. In summer, there is regular passenger navigation connecting Kotlas and Soyga (located approximately halfway between Solvychegodsk and Yarensk).
