It has a drainage basin of 25,900 square kilometres (10,000 sq mi).

[1][2] The river is a spawning ground for salmon and is part of the Magadan Nature Reserve.

[3] The Taui river, as the Kava, is formed at an elevation of 125 m (410 ft) at the confluence of rivers Rasava and Lozovaya flowing from the Kheidzhan Range, Upper Kolyma Highlands.

[4][3] The Taui flows first southeastwards and then roughly eastwards along the Kava-Taui Plain (Кава-Тауйская равнина), a wide floodplain.

The main tributary of the Taui is the 228 kilometres (142 mi) long Chyolomdzha (Чёломджа) that joins it in its lower course from the left.
