The Lakharchana (ru|Лахарчана; sah|Лахарчаана|Laxarçâna), is a river in Yakutia (Sakha Republic), Russia. It is a left hand tributary of the Vilyuy, and is 202km (126miles) long, with a drainage basin of 7130km2.
The river flows across an uninhabited sector of Mirninsky District.[1]
The Lakharchana belongs to the upper stretch of the Vilyuy basin. It originates in lake Lakharchana, a 3.2km2 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.[2] 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 1831km (1,138miles) from its mouth in the Lena.[3] [4]
The main tributary of the river, longer than the Lakharchana itself, is the 204km (127miles) long Khakhsyk joining it from the right. Another important tributary is the 124km (77miles) 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.
