Mamyn

Mamyn is a river of the Selemdzha basin, also known as the Orlovka. It joins the Selemdzha from the right, above the mouth of the Ulma and below that of the Nora. Through the Selemdzha and the Zeya, its waters belong to the great drainage system of the Amur. The surrounding country lies between the broad valleys of the Zeya and the Selemdzha, amid the forests of the northern Amur basin.
