Course

The Agayakan originates in the northern slopes of the Suntar-Khayata, not far from the source of the Yudoma. It heads roughly to the NNW and northwards across the Oymyakon Highlands. Finally the Agayakan meets the Suntar river, flowing from the west, to form the Kyuyente, a tributary of the Indigirka. The river is fed by snow and rain. It freezes in late September or early October and stays frozen until late May to early June.^[3][4][5]

Tributaries

The main tributaries of the Agayakan are the 95 km (59 mi) long Neymechek, the 89 km (55 mi) long Tonskoy and the 85 km (53 mi) long Khongor on the left, as well as the 80 km (50 mi) long Ot-Khaya on the right. there are about 1,500 lakes in the Agayakan basin, with an estimated total area of 44 km² (17 sq mi).^[5]
