The Tolka is one of the main tributaries of the Taz. It is formed in the Siberian Uvaly hills, at the confluence of rivers Ai-Emtoryogan and Pyantymyogan. In its upper course the river heads roughly westwards across the tundra. After a long stretch it bends and meanders in a northeastern direction. Finally, south of the shore of lake Lake Chyortovo (Lozil-To), it bends eastwards, meandering until it meets the left bank of the Taz  from its mouth in the Taz Estuary of the Kara Sea. Tributaries  
The main tributaries of the Tolka are the  long Varky-Chyuelky (Варкы-Чюэлькы) and the  long Kypa-Kelilky (Кыпа-Кэлилькы) on the left. There are numerous lakes and swamps in its basin, the largest of which are lakes Chyortovo and Pyurmato. The river is frozen between mid October and mid May. See also
