The Lakharchana belongs to the upper stretch of the Vilyuy basin. It originates in lake Lakharchana, a 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 from its mouth in the Lena.Tributaries
