Course
The Keyikte is a left tributary of the Namana flowing through uninhabited territory. It is formed in the Lena Plateau. It heads first roughly southwards, then almost halfway through its course, its bends westwards across the plateau meandering strongly within a floodplain dotted with lakes. There are over 300 lakes in its basin. Finally it meets the left bank of the Namana in its middle course, 231 km from its mouth in the Lena.

The Keyikte freezes between the mid October and early May. Its basin is fed by rain and snow. Its main tributaries are the 39 km long Tisik (Тисик) and the 45 km long Maran (Маран) on the left.
