Course of the Chilok (Хило́к) |
The Chilok ( Russian Хило́к , Buryat Хёолго , Mongolian Хялга гол ) is an 840 kilometer long right tributary of the Selenga in Dauria in southern Eastern Siberia .
course
The Chilok flows from the Arachlei Lake , which is about 50 kilometers (as the crow flies) northwest of Chita at an altitude of 965 m . The 58.5 km² large lake lies on the watershed between the catchment areas of the Yenisei and the Lena : it drains over the Chilok to the Yenisei, over a stream in a north-easterly direction to the Witim and thus the Lena. First of all, the Chilok flows through the 53.6 km² large Shakschinskoje Lake (also Shakscha Lake ). The two-kilometer connection between the two lakes is also called Choloi . There are other lakes in the wide valley of the Chilok upper reaches. The largest is the Irgen lake with 33 km², which is connected to the river by an arm.
The Chilok continues to flow on the territory of the Transbaikalia region through a wide valley in a west-southwest direction parallel to the Jablonowy Mountains south of the river . It reaches the autonomous republic of Buryatia and turns sharply north about 100 kilometers above its mouth. Finally it flows into the Selenga, the largest tributary of Lake Baikal, about 70 kilometers southwest of the republic capital Ulan-Ude at an altitude of 522 m .
Throughout the course of the river forms over wide meander and sometimes many kilometers away from each other arms. The most important tributary is the Ungo from the left. The river name is from the Evenk word kilka for grindstone derived.
Hydrography
The catchment area of the Chilok covers 38,500 km². Near the mouth, the river is about 150 meters wide and two meters deep; the flow velocity is 1.8 m / s.
The chilok freezes from October / early November to late April / early May. It can freeze to the bottom in the middle reaches between the end of December and April. The mean water flow (MQ) is 22 kilometers above the estuary 96 m³ / s, with an average monthly minimum of 4.1 m³ / s in February and a maximum of 220 m³ / s in May. During the entire summer months (May to September), the Chilok floods, depending on the rainfall, from year to year.
Infrastructure
The Chilok is navigable for several dozen kilometers in the lower reaches.
There are small towns in almost the entire course of the river. The only city is Chilok, named after the river . The area is therefore relatively well developed in terms of infrastructure. Between the stations of Kuli (km 5812) and Sochondo (km 6096), the Trans-Siberian Railway follows the middle and upper reaches of the river on its right (northern) side for almost 300 kilometers, before crossing it at Sochondo. This section also runs the M55 Irkutsk- Chita road, part of the transcontinental road link, in the river valley.
Further to the west, near the village of Maleta , the Chilok is crossed by the regional road R425 , which starts from Petrowsk-Sabaikalski and leads to Krasny Chikoi and opens up the southwest of the Transbaikalia region on the central reaches of the Chikoi .
The lakes on the upper reaches of the Chilok are holiday, recreation and fishing areas, especially for the residents of the regional capital, Chita.
