The Ilimpeja ( Russian Илимпея ) is a 611 km long left tributary of the Lower Tunguska in Central Siberia ( Russia , Asia ).


The Ilimpeja flows in about 470  m from a small lake below the flat ridge Uramakit, about 270 km as the crow flies southeast of the settlement Tura , administrative center of the former autonomous district of the Evenki , today Evenk Rajon of the Krasnoyarsk region . The source and the entire course of the river lie in the central part of the Central Siberian Mountains .

The Ilimpeja initially flows more than 100 kilometers in south to south-east directions, but then turns sharply north. It maintains this general direction of flow, with many wide arcs through the taiga landscape of the Central Siberian mountainous region throughout the rest of the way. In several sections, including the lower reaches, the valley is narrow and rocky; there have rapids trained. The river finally flows with two arms about 300 kilometers above (east-southeast) of Tura into the large Yenisei tributary Lower Tunguska (Nizhnyaya Tunguska), a good five kilometers below the village of Jukta on the left bank of the Tunguska .

Near the mouth, the Ilimpeja is more than 150 meters wide and two meters deep, and the flow velocity there is 0.8 m / s.


The catchment area of the Ilimpeja covers 17,400 km². Its most important tributaries are the Umnonga, Limptekan, Sungnumo and Dywengne from the left and the Tschungtuke from the right.

The river freezes over from late October to early May.

Use and infrastructure

The Ilimpeja is not navigable due to its rapids a little above the mouth.

The-carrying area is extremely thin by semi-nomadic living reindeer herders settled. There are no settlements in the entire catchment area of ​​the river. The only village in the vicinity is the village Jukta with 134 inhabitants not far from the Ilimpeja estuary on the Lower Tunguska. Accordingly, there is no infrastructure in the area.
