It is a right tributary of the Ob River. The Vakh River is 964 km long; the area of its basin is 76,700 km². It begins at the watershed of the basin of the Ob, the Yenisei, and the Taz Rivers. The Vakh River''s main tributaries are the Kulynigol, the Sabun, the Kolikyegan, and the Bolshoy Megtygyegan. Since the Vakh, like the Ket River, flows from east to west, it was an important early transportation route. A short portage connects its headwaters to the Sym River, which flows into the Yenisei.
