There are no settlements located by the river, but there is industrial production of table salt in the basin. Balagannakh village is located near the mouth of the Namana in the Lena.[1] The river flows near a landfill where there have been leaks leading to oil pollution of its waters.[3]

Course

The Namanа is a left tributary of the Lena flowing through uninhabited territory. It is formed at the confluence of the Usttaakh and Orguy rivers in the Lena Plateau. It heads across the plateau through a narrow valley, meandering increasingly. After descending into the floodplain it flows in a roughly southern direction within a wide basin dotted with lakes. Finally it meets the left bank of the Lena 2,044 kilometres (1,270 mi) from its mouth, 50 kilometres (31 mi) northeast of the city of Olyokminsk. The river basin is fed by rain and snow. Floods are common in the summer period.[1][4][5]

Tributaries

The largest tributaries of the Namana are the Dyeberelekh, Sarsan and Yulagir from the right; and the Yoksyondyo, Bas-Yurekh, Ulakhan-Arbay, the 276 km (171 mi) long Keyikte (Кэйиктэ), Kuchugui-Nygydyakh, Mukhta and Dielimde (Anabyl) from the left. The river freezes between the end of October and May.[1][5]

Flora

The vegetation of the Namana basin is mainly larch taiga, mostly not dense. The snow cover in the river basin lasts between November and April.[1]
