The Buotama (Russian: Буотама) is a river in the Sakha Republic, Russia. It is a right tributary of the Lena and has a length of 418 km.
There is a nursery of wood bison by the Ust-Buotama Reservoir on the lower reaches of the river. It was opened in 2006 with bison imported from Canada.
The river has its source in the northern part of the Aldan Highlands at an elevation of almost 500 metres. It flows in an approximately ENE direction roughly parallel to the Lena through a relatively narrow valley by the Lena Plateau. Finally it makes a bend northwards and joins the right bank of the Lena, about 100 km upstream from the capital Yakutsk and 1,609 km from the Lena\'s mouth.
The Buotama freezes between October and November and thaws between the end of April or early May.
