Course
The Kasmala is a left tributary of the Ob river. It has its sources in lake Seleznevo-Borovskoye, located 30 km northeast of lake Bolshoye Ostrovnoye in a swampy area of the Ob Plateau. The river flows in a roughly northeastern direction within one of the wide ravines of glacial origin that cut diagonally across the plateau. Finally it meets the left bank of the Ob at Kasmala, 3343 km from the Ob's mouth.

Tributaries
The longest tributary of the Kasmala is the 32 km long Borovlyanka (Боровлянка) on the left. The river is frozen between November and April.
