The Chyorny Anuy and the smaller Bely Anuy join to form the Anuy river. The Chyorny Anuy starts at an altitude of 1,220 m at the southeastern end of the Anuy mountain range in the Altai Republic. Flowing in a northwestern direction, it enters Altai Krai after about 40 km. The two rivers join near Soloneshensky District.
The Anuy River exits the Altai mountains at an altitude of 250 m and flows in a northeastern to eastern direction. Near the village of Anuyskoye, the river takes a northern direction and joins the Ob River near Biysk at an altitude of about 150 m.
The drainage basin of the Anuy River encompasses about 6,930 square kilometers (2,680 sq mi).
The average flow at Staro-Tirishkino, about 10 km near the river's end, is about 36.1 m3/s with a minimum of 6.9 m3/s in February and a maximum of 123 m3/s in April.
The Anyuy River is frozen between November and April. It is not navigable.
