Lakharchana

The Lakharchana (Лахарчана; Лахарчаана), is a river in Yakutia (Sakha Republic), Russia. It is a left hand tributary of the Vilyuy, and is 202 km long, with a drainage basin of 7130 km2.

The river flows across an uninhabited sector of Mirninsky District.

Course
The Lakharchana belongs to the upper stretch of the Vilyuy basin. It originates in lake Lakharchana, a 3.2 km2 lake of the Vilyuy Plateau, flowing out of it from the eastern lakeshore. It heads first eastwards for a short stretch and then bends southwards, bending again and heading to the west for another short stretch until it finally bends to the south and heads roughly in that direction across the plateau. About midway through its course it bends and flows roughly southeastwards meandering in a floodplain among smooth hills. Finally, it meets the left bank of the Vilyuy 1831 km from its mouth in the Lena.

Tributaries
The main tributary of the river, longer than the Lakharchana itself, is the 204 km long Khakhsyk joining it from the right. Another important tributary is the 124 km long Byotyoryo (including the Ivan-Kyuyolyun-Seine tributary at its head) from the right. The Lakharchana freezes in mid October and stays under ice until late May.
