The Tolka (Russian: Толька; Selkup: Толь-кы) is a river in the Yamalo-Nenets Autonomous Okrug, Russia. It has a length of 391 kilometres (243 mi) and a drainage basin area of 13,300 square kilometres (5,100 sq mi).[1]
The river flows north of the Arctic Circle, across territories of the Krasnoselkupsky District marked by permafrost and swamps.[2][3]
Course
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 723 km (449 mi) from its mouth in the Taz Estuary of the Kara Sea.[2][4][3]
Tributaries
The main tributaries of the Tolka are the 141 km (88 mi) long Varky-Chyuelky (Варкы-Чюэлькы) and the 141 km (88 mi) 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.[2][5][1]
