The Volga River's watershed (area of land drained by the river) is 532,821 square miles in size, and includes most of Western Russia. The Volga River's major tributaries are Kama River and Oka River. There are approximately 200 other tributaries that join the Volga River along its route. Major cities that the Volga River passes through include Astrakhan, Volgograd, Saratov, Samara, Ulyanovsk, Kazan, Nizhny Novgorod, Yaroslavi, and Tver.
The Ob-Irtysh is the world's seventh-longest river at 3,354 miles long. It begins at the junction of the Biya and Katun rivers, in the Altai Mountains, and flows through Siberia to the Gulf of Ob. It is made up of the Ob, the main river, and the Irtysh, its main tributary. Geographers most often refer to the two together, as the Ob-Irtysh River. Other large tributaries include the Tom, the Chulym, the Ket, the Tym, the Vakh, the Vasyugan, and the Sosva. But only the Irtysh, as the main tributary, gets its name in the title.
