Tuva (Russian: ÑÑÐ²Ð°Ì tyh-VAH) or 'Tyva' is a republic in Eastern Siberia, bordering the Altai Republic to the west, Khakassia to the northwest, Krasnoyarsk Krai to the north, Irkutsk Oblast to the northeast, Buryatia to the east, and Mongolia to the south.
Its watershed, which includes Lake Baikal, holds more water than any other river system. Yenisei's tributaries include famous Angara, Nizhnyaya Tunguska, and Tuba rivers.[ Yenisei (Yenisey, ÐÐ½Ð¸ÑÐµÐ¹) rises in the mountains of Russia near the Mongolian border and flows generally northward through Siberia into the Kara Sea, Arctic Ocean. The river is often considered the boundary between Western and Eastern Siberia. The Yenisei and its tributaries are rich in fish, including salmon and sturgeon. As the river flows north towards the sea it travels through taiga forests which change into a tundra.
