Course

The Churo is a right tributary of the Upper Angara River. Its sources are in an unnamed alpine lake of the western area of the Delyun-Uran Range. In its upper course it flows first southwestwards then westwards across a swampy valley. After bending southwards, its course marks the eastern limit of the Upper Angara Range. Finally, after meandering in a floodplain with lakes, it meets the Upper Angara 270 km from its mouth in Lake Baikal. The main tributaries of the Churo are the Avaikan, Uklon, Uanymi and Churokan. The river is frozen between October and May.
