The Shuja ( Russian Жуя ) is a 337 km long left tributary of the Tschara in Eastern Siberia ( Russia , Asia ).
course
The Schuja rises at an altitude of about 1250 m in the southwest part of the Patom highlands , which are almost 1700 meters high , about 100 kilometers east of the city of Bodaibo . It flows through the highlands first in a north to north-easterly direction, then turns to the east and finally flows into the Tschara at the village of Tschara (also called Ust-Shuja ) at an altitude of 246 m .
The most important tributaries are Watscha and Khomolcho from the left and Netschera and Tschentscha from the right. The Shuja flows through the northeast of Irkutsk Oblast along its entire length .
Hydrography
The catchment area of the Shuja covers 22,600 km². Near the mouth, the river is over 200 meters wide and around 3 meters deep; the flow velocity is 0.6 m / s.
The Shuja freezes from October to May and leads to floods from the snowmelt and throughout the summer. The water flow on the middle course, at Swetly , 246 kilometers from the mouth, is an annual average of 53 m³ / s with a minimum of 2.1 m³ / s in March and a maximum of 223 m³ / s in June.
Infrastructure and economy
The Schuja is navigable for 246 kilometers from Swetly below the confluence of the Watscha.
The area through which the Shuja flows is sparsely populated. However, there are smaller towns along the entire length of the river, such as Perewos opposite the mouth of the Khomolcho. At the Svetly gold rush settlement and at Perewos the river is reached by unpaved roads that connect to the urban-type settlement of Kropotkin and Bodaibo. In winter the frozen river serves as an ice road.
The upper catchment area of the Shuja, especially its tributary Watscha, has been an important gold mining area since the 19th century . Here, in the northern part of the “Witim gold fields”, gold mining began in 1862 around Tichono-Sadonski, today's Kropotkin.
