The Ilim ( Russian Илим ) is a 589 km long right tributary of the Angara in Siberia ( Russia , Asia ).
The Ilim rises at a height of about 800 m in the southeastern part of the Central Siberian mountainous region and flows through it over its entire length in a mostly narrow valley in a northerly direction, roughly parallel to Angara and the upper reaches of the Lena . The river will always remain on the territory of Irkutsk Oblast . 40 km south of the city of Ust-Ilimsk (Russian ustje Ilima for Ilim estuary ) the Ilim flows into the Angara. Since 1977 the Angara near Ust-Ilimsk has been dammed up to the Ust-Ilimsk reservoir , and with it the lower reaches of the Ilim up to above Zhelesnogorsk-Ilimski (water level at 296 m ).
The catchment area of the Ilim covers 30,300 km². The mean monthly water flow at the village of Sotnikowa (52 km above the mouth) was 139 m³ / s before the Ust-Ilimsk reservoir was dammed. The most important tributaries are the Kotschenga and Tuba from the right and the Chora from the left .
The Ilim freezes from late October to early May.
From 17th to 19th century, the Ilim part of was Lena Treidelroute (Russian Lenski Wolok ) which over Ilim, Muka and Kuta joined the Angara with Lena. Shipping was made difficult by the Simacha rapids (Russian: Simachinski porog ) eight kilometers above the mouth of the Ilim. Since these and other rapids were flooded, the Ilim has also been navigable for larger ships in the area of the Ust-Ilimsk reservoir (a good 200 km to Shestakovo near Schelesnogorsk-Ilimsky). At Shestakovo ( Sredneilimskaja station ) the Baikal-Amur main line also crosses the river on a 450-meter-long bridge. This is the only railway bridge over the Ilim; the bridge over 50 km downstream on the Bratsk - Ust-Kut road is the only road bridge.
