The Kuta ( Russian Кута ) is a 408 km long left tributary of the Lena in Siberia ( Russia , Asia ).
course
The Kuta rises at a height of about 650 m in the southeast of the Central Siberian Mountains , initially flows mainly to the west, then to the south in a wide, partly swampy valley overgrown by taiga . At the confluence of the only significant tributary, the Kupa, from the right, the river turns sharply to the east. From here it flows in a relatively narrow and deep valley in wide arches and finally flows into the Lena at the city of Ust-Kut (Russian for "Kuta estuary"), which is named after it, at a height of 284 m .
The Kuta flows through the territory of Irkutsk Oblast along its entire length .
Hydrography
The catchment area of the Kuta covers 12,500 km². Above the delta of the mouth, the river is 50 meters wide and one meter deep; the flow velocity is 0.7 m / s.
The mean water flow in the village of Rutschei, below the confluence of the Kupa and 52 km above the mouth, is 61.4 m³ / s, with a minimum monthly mean of 14.6 m³ / s in March and a maximum monthly mean of 348 m³ / s in May.
The Kuta freezes between November and early May.
Infrastructure
The Kuta is not navigable.
The area of the upper and middle reaches of the river is practically unpopulated, but is used for forestry. There are relatively many smaller towns, including the urban-type Jantal settlement , on the lower reaches of the Kupa estuary.
The Taischet – Ust-Kut railway line ( Lena station ) was built along the Kupa and Kuta rivers in the 1950s. It went into operation in 1958 and is now the western section of the Baikal-Amur mainline . The railway line crosses the river three kilometers below the mouth of the Kupa and follows it on the left for about 60 kilometers to the mouth. The R419 regional road from Tulun via Bratsk to Ust-Kut runs parallel to this section .
