The Ussuri River or Wusuli River (Russian: река Уссури; Chinese: 乌苏里江; pinyin: Wūsūlǐ Jiāng), runs through Khabarovsk and Primorsky Krais, Russia, and the southeast region of Northeast China. It rises in the Sikhote-Alin mountain range, flowing north and forming part of the Sino-Russian border (which is based on the Sino-Russian Convention of Peking of 1860) until it joins the Amur River as a tributary to it at Khabarovsk ( ). It is approximately 897 kilometers (557 mi) long. The Ussuri River drains the Ussuri basin, which covers 193,000 square kilometers (75,000 sq mi). Its waters come from rain (60%), snow (30–35%) and subterranean springs. The average discharge is 1,150 cubic metres per second (41,000 cu ft/s) and the average elevation is 1,682 metres (5,518 ft).
The Ussuri River has a reputation for catastrophic floods. It freezes up in November and stays under the ice until April. The river teems with different kinds of fish: grayling, sturgeon, humpback salmon (gorbusha), chum salmon (keta) and others.
