The length of the river is {{convert|723|km|mi}}. The area of its basin is {{convert|55500|km2|mi2}}.{{GVR|293473|Река АМГУНЬ}} The Amgun is formed by the confluence of the Ayakit and Suluk. Its main tributary is the Nimelen.[http://bse.sci-lib.com/article038111.html Амгунь], Great Soviet Encyclopedia The Amgun teems with fish, such as Siberian salmon, humpback salmon, sturgeon, and carp. The Baikal Amur Mainline railway enters the Amgun valley from the Dusse-Alin Tunnel and follows the river {{convert|180|km|mi}} northeast to Beryozovy where it turns southeast to Komsomolsk-on-Amur.
