The Rybnaja ( Russian Рыбная ) is the approximately 138 km long southeast or left-hand source river of the Norilka , in the north of the Krasnoyarsk region , of Siberia and Russia ( Asia ).

geography

course

The Rybnaja runs on average around 285 km north of the Arctic Circle between the eastern Putorana Mountains (max. 1701  m ), the rocky northwestern part of the Central Siberian Mountains , and the western Lontokoiski-Kamen Mountains (max. 760  m ), the outer northwestern part of this mountainous region . You entfließt the on 85  m located height Lake Keta . From then on it runs between the two mountains, winding through unpopulated area in a north-westerly direction.

Finally, the Rybnaja joins far above the Valjok on the Norilka at about 29  m height, i.e. after a height difference of about 56 m, with the Talaja to the Norilka coming from the east from the Melkojesee .

Tributaries, lakes and catchment areas

The tributaries of the Rybnaya, whose catchment area is 6,600 km², include the Omne and Gremjaka . The Ketasee and numerous small lakes are in the catchment area .

Hydrology, climate and flora

The hydrological regime of the Rybnaja is determined by harsh winters and short summers due to its northern location and the associated proximity to the Arctic . There is a lot of precipitation all year round, and the presence of numerous still and flowing waters in its rather large catchment area play a regulating role in the water balance. The river is covered in ice from late September to mid-June . When ice and snow melt in summer , floods often occur between June and August .

The Rybnaja runs in the climatic zone of the permafrost , on its banks boreal coniferous forests (taiga) thrive and on the mountains of the surrounding mountains there is tundra with mosses and lichens . The river is the habitat of many arctic species - for example perch fish , pike and salmon fish .

environmental pollution

The factories of the industrial group MMC Norilsk Nickel , the world market leader in the production of nickel and palladium , located in the Norilsk region , cause severe environmental pollution - for example on the Rybnaya .
