History

The first Russian to enter the area was Vassili Poyarkov.

Course

It rises in the Tokiysky Stanovik mountain ridge, a part of the Stanovoy Range.

The Zeya flows through the Zeya Reservoir, at the junction of the Tukuringra Range and Dzhagdy Range, and joins the Amur near Blagoveshchensk, at the border with China. Regulation of river discharge by Zeya Dam mitigates extremities of river flow down to 5000 m³/s.

The main tributaries of the Zeya are Tok, Mulmuga, Bryanta, Gilyuy, and Urkan on the right, and Kupuri, Argi, Dep, Selemdzha, and Tom on the left.[3]

The river freezes from November to May. It is navigable with the most important river ports being Zeya, Svobodny, and Blagoveshchensk.
