The Ochchuguy-Botuobuya (Russian: Оччугуй-Ботуобуя or Малая Ботуобуя;[1] Yakut: Оччугуй Ботуобуйа, Oççuguy Botuobuya) is a river in the Republic of Sakha in Russia. It is a right hand tributary of the Vilyuy, and is 342 kilometres (213 mi) long, with a drainage basin of 11,100 square kilometres (4,300 sq mi).[2]
The river begins in the Lena Plateau at an elevation of 317 metres (1,040 ft). It flows roughly northwards through a wide valley with the larger Ulakhan-Botuobuya running parallel to it further to the west. Finally, it joins river Vilyuy from the right near Khampa village. The river freezes between October and late May.[3]
The main tributaries of the Ochchuguy-Botuobuya are the Irelyakh and the Kharya Yuryakh. The town of Almazny is located at the confluence of the Ochchuguy Botuobuya and the Irelyakh.[4]
