There is a bridge of the Yakutsk â Amga â Ust-Maya highway across the river. It was inaugurated in November 2018.
The Notora has its sources in the fringes of the Lena Plateau near Amga village, not far to the southeast from the Amga river valley. The river flows roughly eastwards all along its course. In its last stretch it enters the wide floodplain of the Aldan and makes a slight bend to the northeast. Finally it meets the left bank of the Aldan River from its confluence with the Lena River.
The main tributaries of the Notora are the long Khatarchyma (Uulakh-Salaa), the long Nyigirime and the long Dukha (ÃÂÃÂÃÂàð) on the left. The Notora is fed mainly by snow and rain. Floods are frequent in the summer and its flow decreases significantly in the winter. There are about 1,200 lakes in the river basin.
