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]
