The Nuchcha flows north of the Arctic Circle, across desolate territories of the Ust-Yansky District. An abandoned village named "Batagay" was located by the riverside in its lower course.

Course

The Nuchcha is a right tributary of the Chondon. It has its sources in the northern slopes of the Kyun-Tas range. The river flows roughly northwards within a valley. After it leaves the mountainous terrain it heads across the Yana-Indigirka Lowland floodplain to the southwest of the Sellyakh. It flows slowly through flat terrain where it meanders very strongly among numerous lakes. Finally the river joins the Chondon from its mouth. Tumat, the nearest inhabited place, is located nearly upstream of the confluence.

Tributaries

The main tributaries of the Nuchcha are the long Bylaat-Yurege and the long Buruuchaan-Yurege on the right, as well as the long Ekechan on the left. The river is frozen between the beginning of October and the beginning of June. There are more than 1,300 lakes in its basin.
