The Iomrautvaam has its source in the Komeutyuyam Range of the Koryak Highlands. It flows in a roughly northeastern direction in the northern section of the range. Finally it meets the right bank of the Khatyrka 100 kilometres (62 mi) from its mouth, close to the northeastern end of the ridge.[2][3][4][5]
