formed by the merger of two of the Altai rivers - Biya and Katun river Ob in fact continues to Katun.The confluence of these powerful enough reservoirs formed more torrent.And every river - its color.Biya has a white or dirty-gray color, and Katun - green.United in a common stream of water for some time, do not mix, resulting in a multi-colored striped water jet.Especially well this phenomenon is observed in summer and autumn.Falling into the Kara Sea, Ob forms a large bay with a length of about 800 kilometers, which is called the Ob lip.

Together with its tributary the Irtysh, the Ob river in the first place longest in Russia (5410 km.) And the second - in Asia.The area of ​​its basin - nearly 3 million sq. M.km.According to how the character of the river network, the food and forming the water regime of the river Ob can be divided into three major sections: the upper (from the source to the mouth of the river Tom), medium (up to the mouth of the Irtysh River) and bottom (to the Gulf of Ob).Filling the river water is mainly due to melting snow, and the bulk of the flow occurs during spring and summer.In the upper reaches of the flood it is usually in early April, the average - in the middle of the month, and at the bottom - in late April-early May.The rise of the water level at freeze-up begins.With the opening of the river may be short-lived intense water level rises due to ice jams.It is possible to even change the direction of flow in some tributaries of the Ob.In the upper reaches of the flood may last until July, summer low flow is uncertain, and in September-October rainfall is flooding.Recession floods in the middle and lower reaches may continue until freeze-up.Obi many large (Irtysh Charysh, Anouilh, Aley, Chumysh, Bird, Chulym, Tom, etc..) And small tributaries.

have origin of the name of the pond several versions.So, from the language of the Komi word "Ob" translates as "snow" or "snowdrift".Another version says that the river was his name from the Persian "about" ("Water").There is also a version that laid the basis for the name of the Russian word "both" because the source of the river Ob formed by the merger of two bodies of water.Each theory has a right to exist.

Ob River is important for the whole of the West Siberian region.It is used as a natural transportation route, especially for summer delivery of fuel and food in northern areas, reachable only by river.In the southern part of Novosibirsk Reservoir is located (also called Ob Sea) formed built in 1950-1961 gg.dam Novosibirsk GES.In the Ob waters inhabited by about fifty different species and subspecies of fish, almost half of which are target species (mainly fine-mesh - pike, burbot, bream, perch, ide, roach, etc.).Also in the usual river sturgeon, sturgeon, white salmon, whitefish, and others.Ob River, especially in its upper reaches, is traditionally used as a resting place.There are many resorts and tourist centers (especially in the area of ​​the Novosibirsk Reservoir), known not only in Russia but also abroad.
