The Tumara (Russian: Тумара; Yakut: Тумара) is a river in the Sakha Republic (Yakutia), Russia, a right tributary of the Aldan, part of the Lena basin. It flows across an area that is largely desolate, except for Segyan-Kyuyol village.[1] The Tumara has a length of 236 kilometres (147 mi) and a drainage basin area of 10,300 square kilometres (4,000 sq mi).[2] The river is a destination for rafting.[3]

The name of the river comes from the Yakut language tumara, meaning "tundra".[4]

Course

The Tumara originates in the slopes of the southwestern Verkhoyansk Range. In the upper section of its course the river displays all the characteristics of a mountain river, flowing roughly southwards within a deep and narrow valley bound by steep slopes that cuts across the Kelter (Көлтөр) and Munni (Мунний) ranges.[5]

After leaving the mountainous area in its middle course the Tumara flows through a floodplain and forms meanders, still following a generally southward direction. In its lower course the river expands and the floodplain becomes wider, its riverbed dividing into slowly-flowing arms. Finally the Tumara meets the right bank of the Aldan River, a little upstream from Batamay and downstream from river Kele.[5]

Its longest tributaries are the 110 km (68 mi) long Nuora (right) and the 78 km (48 mi) long Nyorkyunde.[3]
