Shish
The Shish flows through the forests and wetlands east of the Irtysh before joining that river near Ust-Shish. It rises in the Vasyugan bog country and winds across the western Siberian lowlands. In its lower course it turns north-west and runs for a time parallel to the Irtysh, then bends south-west towards their meeting. Its tributaries include the Bolshoy Kutis, which enters from the right.
