Chyna (river)

The Chyna (Чына; Чына) is a river in Yakutia (Sakha Republic), Russia. It is the longest tributary of the Sinyaya of the Lena basin, with a length of 240 km and a drainage basin of 5070 km2.

The river flows across the mostly uninhabited territory of Gorny District. The nearest inhabited place is Dikimdya village, located about 60 km northeast of its mouth.

Course
The Chyna begins in the southern sector of the Lena Plateau, near the sources of the Markhachan. It flows first roughly southeastwards across the plateau. About midway through its course the river bends in a wide arch and heads northeastwards, meandering strongly within the floodplain. Finally it meets the right bank of the Sinyaya, a tributary of the Lena, 177 km upstream from its mouth. The river freezes in the second half of October and stays under ice until the second half of May.

There are about 150 lakes in the river basin. The main tributaries of the Chyna are the 66 km long Keibele and the 54 km long Tyympynay (Tyympy) from the left.
