To go

There is no generally accepted version of origin. The most ancient is the connection with the ethnonym Issedona , recorded by ancient Greek historians. Tatar ( is et - dog smell) and Ket ( ise set - fish river) versions were offered. Nevertheless, there are no traces of the presence of Issedons or Kets in the Urals, the Tatar etymology is mechanistic and violates the laws of the language (word order). A.K. Matveev compared the name with the hydronyms Is and Isa, but he did not receive convincing conclusions.

Rychkov Pyotr Ivanovich in his book “Orenburg Topography” (p. 229) wrote:

Iset, in the Orenburg province and in the Iset province , emerged from Isetskago Lake above Yekaterinburg, about twenty kilometers, flowed eastward past Yekaterinburg, Kamenskago, Katayskago, Shadrinskago and Isetskago ostrogov, and emptied to Tobolor to the utmost. On it are stony places and rapids. The newly established Iset Province from it has its own name.

Since the 18th century, factories have been built on Iset and its tributaries ( Verkh-Isetsky , Uktussky , Yekaterinburg ). A little later, it became a place of gold mining .

Flora and fauna Iseti is experiencing a serious negative impact of industrial enterprises and housing and communal services, the treatment of wastewater and other wastewater from the city of Yekaterinburg is carried out. So, in 2008 there was a massive death of fish due to lack of oxygen . Chemical and bacterial pollution is regularly observed in the Yekaterinburg ponds.

In the report of the Ministry of Natural Resources and Ecology for 2007, the river was named one of the most polluted in Russia over the past 15-20 years ^[3] .

The Miass River, which flows through the large industrial cities of Miass and Chelyabinsk, also contributes to anthropogenic pollution.

Below the mouth of the Techa River, radioactive contamination of the Iset River is noted due to the natural transfer of radionuclides by the flow from it. Part of Iseti itself and its upstream drainage basin , as well as the upper Sinara River and its drainage basin, are located in the East Ural radioactive trail zone. And even in 2009, in the water of the Iset river below the mouths of the Techa and Miass (near the village of Mekhonskoye, after diluting the Techa water with the non-contaminated waters of Miass and the upper Iset), the strontium-90 content was 0.82 Bq / l, which is 6 times lower than the level requiring urgent intervention to reduce according to NRB-99/2009, but exceeds the background level for rivers by approximately 163 times ^[4] .

The river ichthyocenosis is quite diverse - pike, pike perch, perch, ruff, bream, roach, ide, tench, dace, crucian carp and others. The fish productivity of the river is 10-12 kg / ha. Dates of mass spawning of fish are recorded from the third decade of April to the second decade of May. Spawning is common in the third decade of May, tench in June, burbot in December and January.

2 types of fish migration are clearly expressed - spring migration along flood-spawning pastures and autumn migration to wintering pits (“Dredger”, “Nikolskaya”, etc.).

Since 1951, on Iset, below the mouth of the Techa River, due to its radioactive contamination, drinking water and fishing were officially banned (for a wide range of the population without explaining the true reason) ^[5] ..

In accordance with the Water Code of the Russian Federation dated December 28, 13 No. 74FZ, the width of the water protection zone of the Iset River is 200 meters.

According to the state water register of Russia, it belongs to the Irtysh basin district , the water sector of the Iset river from the confluence of the Techa River to the mouth, without the Miass River, the river sub-basin is Tobol. The river basin of the river is the Irtysh ^[6] .
