Course
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.[3][4] 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 706 km (439 mi) from its confluence with the Lena River.[5][3][4]
Tributaries
The main tributaries of the Notora are the 48 km (30 mi) long Khatarchyma (Uulakh-Salaa), the 41 km (25 mi) long Nyigirime and the 67 km (42 mi) long Dukha (Дьуха) 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.[4][6]
