Khoruongka

The Khoruongka (Хоруонгка, Хоруоҥка, Xoruoŋka) is a river in the Sakha Republic (Yakutia), Russia. It is a left tributary of the Lena. Its length is 377 km and the area of its basin is 8330 km2. The Khoruongka flows across Zhigansky District, not far to the west of Zhigansk town.

The basin of the Khoruongka falls fully within the Central Yakutian Lowland and parts of it are a protected area. The banks of the river are uninhabited.

Geography
The Khoruongka originates in Biedili, a small lake of the Central Yakutian Lowland. It flows first in a SSE direction within a swampy floodplain, then it bends eastwards. After a short stretch it bends again northeastwards, flowing finally almost northwards to the west of the course of the Lena to the north of the Nuora. The area where the Khoruongka flows is dotted with small lakes, especially to the west of its course. The Khoruongka meets the left bank of the Lena 696 km upstream of its mouth in the Laptev Sea. The Sobolokh-Mayan has its mouth approximately on the opposite side of the Lena.

The main tributaries of the Khoruongka are the 82 km long Kyundarimi, the 155 km long Samaldikan and the 79 km long Kirginnyekh, all from the left.
