Bikinka

Bikinka belongs to the Ussuri basin, a long river system that rises in the Sikhote-Alin mountains of Northeast Asia. The Ussuri flows about 897 kilometres northward and joins the Amur near Khabarovsk. For most of that course it forms a boundary between Russian territory and northeastern China. Rain supplies roughly sixty percent of the river’s water, while melting snow contributes thirty to thirty-five percent and springs make up the remainder.

This mixture produces a powerful seasonal pulse and a reputation for severe floods. Ice covers the river from November until April, temporarily interrupting navigation. Beneath the water live grayling, sturgeon, chum salmon, humpback salmon and many other fish. The river’s basin covers 193,000 square kilometres and receives several large tributaries, including the Bikin.

Bikinka’s place in this drainage connects it to forested mountains, floodplains and a major northward passage toward the Amur. The river also supports migrations of salmon and offers habitat for the Ussuri brown bear and Ussurian tiger in its wider catchment. Winter ice and spring melt strongly affect routes on both banks. Ice and flood cycles rule its seasonal rhythm.
