Irtysh River being the largest tributary of the Ob River, holds several records length.Ob with the Irtysh - have the greatest length among the rivers of Russia, taking up second place in Eurasia and the seventh - in the world.In addition, the Irtysh River is the largest river in the world, the influx, pushing the US into second place Missouri.The source of the Irtysh - in China, more than five hundred kilometers of the river runs through the country, and then crossing the border, seventeen hundred kilometers flows through the territory of Kazakhstan, and the remaining two thousand kilometers - on the territory of Russia.
When you look at a map can see that rather not Irtysh River is a tributary of the Ob and Ob - Irtysh tributary.Since at the confluence of the Irtysh river flowed both in the same direction, and continues to flow, but the Ob, on the contrary, sharply changes direction.Rather, the point is that, while mastering Western Siberia, Russian first recorded hydronym Ob, and only later - the name of the Irtysh, mistakenly believing its tributaries.So since then and was fixed on the charts: consider the Irtysh tributary of the Ob River.Although it would be logical, considering the length or give a name to the Ob River to the source of the Irtysh River, and the portion of the hydraulic system, which is called Ob before meeting with the Irtysh, to call in some other way, or the whole river called the Irtysh, from source in China to the mouthin the Kara Sea.
But no wonder they say: "What is written with a pen, will not cut down with an ax."Once recorded on maps and documents - and so remained for centuries.
Irtysh River mostly flat, only in the upper reaches of the proceeds in the highlands.The average slope of the river is very small - three centimeters per kilometer length.The catchment area of one million six hundred forty-three thousand square kilometers.
The flat river made it almost impossible to use it as a source of power: the construction of hydropower plants is extremely difficult.In today operates one hydroelectric in Kazakhstan, but still far from Omsk in 2010. The construction of hydroelectric Krasnogorsk.For a full-flowing river and extended it - a drop in the sea.

Another major tributary of the Irtysh - Tobol.Its length is slightly more than a thousand kilometers.Tobol navigable 470 kilometers from the confluence of the Irtysh.On the Tobol built several reservoirs with which regulated the flow of water during spring flood.Tobol, the inflow of the Irtysh River, gave the name of a large Russian city of Tobolsk.More on Tobol are two regional centers: Kustanai (Kazakhstan) and Barrow (in Russia), and several smaller cities: Lisakovsk, Ore, Yalutorovsk.
Irtysh belongs to the basin of the Arctic Ocean, it is home to many valuable species of fish.Here, a complete set for every taste and salmonids (whitefish, white salmon, some others), sturgeon (Siberian sturgeon), and a large number of less "noble" fish: pike, perch, carp, perch, ruffe, rudd, and many others.
