The Wagai ( Russian Вага́й ) is a 555 km long left tributary of the Irtysh in the south of the West Siberian lowlands ( Russia ).

course

The Wagai has its origin at 128  m in a drained bog about 40 kilometers east of the city of Zavodoukowsk . Originally it escaped without a distinct spring about 3.5 km southeast of the moor, which was even more extensive a few decades ago, before it was connected by a ditch with the lake called Bolshoye Ryamovoye .

Initially, the Wagai flows for about 100 kilometers in an easterly direction, before turning north to north-northeast direction, which it - increasingly meandering - up to its confluence a good 50 km as the crow flies southeast (over 100 river kilometers upwards) of the city of Tobolsk into the Irtysh.

The main tributaries of the Wagai are the Jemez, Balachlei and Agitka from the right and the Aschlyk from the left. The Wagai flows along its entire length in the territory of the Tyumen Oblast .

Hydrography

The catchment area of the Wagai covers 23,000 km².

The mean annual runoff in the village of Novowyigryschnaja, located on the central reaches about 300 kilometers above the estuary, is 9.3 m³ / s with a monthly minimum of 1.37 m³ / s in February and a maximum of 61.7 m³ / s in April . The river carries very little water from June to March, only a multiple during the snowmelt from April to May / beginning of June.

Above the mouth, the Wagai is over 100 meters wide and up to four meters deep; its flow velocity here is 0.3 m / s.

Economy and Infrastructure

The lower reaches of the Wagai are navigable for smaller vessels, but are not considered an official inland waterway.

In its entire course, the Wagai flows through relatively densely populated area, which is mainly used for agriculture up to the middle reaches, then increasingly for forestry. Although there are no cities directly on the river, there are a number of larger villages and district administrative centers , such as Omutinskoje and Aromaschewo as well as the two villages named after the river Wagai in the Rajon Omutinski near the source and Wagai a few kilometers above the mouth as the administrative center of the Rajon of the same name.

To the right of the upper section of the river, which flows in an easterly direction, the Trans-Siberian Railway runs roughly between the stations Wagai (km 2283) and Golyschmanowo (km 2350), some distance parallel to the river. In the same direction, the federal highway R402 runs from Tyumen to Omsk , which crosses the river near the source and again at the village of Ust-Lamenka.

history

The force as a Russian "Conqueror of Siberia" Cossack - Ataman Ermak Timofeyevich drowned in August 1585 at the mouth of the Wagai in the Irtysh.
