The Ussuri River (Chinese: 乌苏里江), or Wusuli River, runs in Khabarovsk and Primorsky Krais, Russia, and in the southeast 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 to 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 m³/s and the average elevation is 1,682 m.
The Ussuri River is known for its 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.
