Selemdzha in Depth
Course
The Selemdzha has its source where three mountain ranges meet the Bureya Range, the Dusse-Alin from the south, the Ezop Range from the west and the Yam-Alin from the north, and flows first northwest with the Selemdzha Range to the north, and then westwards across the Zeya-Bureya Plain. The Baikal–Amur Mainline crosses the river just west of Fevralsk and reaches the Zeya north of the Trans-Siberian Railway and Blagoveshchensk.
Its main tributaries are the Ulma and Byssa on the left, as well as the Nora and Orlovka (Mamyn) on the right. The Selemdzha freezes up in early November and stays under the ice until early May.
