Nemptu
The Nemptu, also called the Nemta, rises in the mountains south of the Amur and flows north to Lake Sindinskoye. The lake in turn drains through a channel into the Amur. Along its lower course, the river bends between eroded banks and sandy shallows, receiving the Mukhen and other tributaries before reaching the lake. Its headwaters lie on a watershed separating the Amur tributaries from those of the Khor.
