The Kazym is a right tributary of the Ob. Its sources are in the Siberian Uvaly. It flows through the northern part of the West Siberian Plain meandering across a very swampy valley. There are numerous lakes in its basin, including the relatively large Sorum-Lor and the Saran-Kho-Lor. The Kazym river is fed mainly by snow. It freezes in early November and begins to thaw in late May.
The main tributaries of the Kazym are the 374km (232miles) long Amnya, the 285km (177miles) long Lykhn and the 156km (97miles) long Pomut on the left, as well as the 190km (120miles) long Sorum on the right.[1]
