Course
It flows roughly northwards across the tundra along a valley limited by the Sietinden Range to the west and the Kular Range to the east. Both ranges are part of the Verkhoyansk Range system. The Omoloy flows through the East Siberian Lowland into the Laptev Sea. Its mouth is located in the eastern coast of the Buor-Khaya Gulf. The river freezes up in October and stays under ice until late May or early June.
Tributaries
The main tributaries of the Omoloy are the 279 km (173 mi) long Kuranakh-Yuryakh, the 190 km (120 mi) long Arga-Yuryakh, the 91 km (57 mi) long Bukhuruk (Бухурук) and the 98 km (61 mi) long Sietinde (Сиэтиндьэ) from its left side, as well as the 159 km (99 mi) long Ulakhan-Kyuegyulyur from the right.[4][1]
