Irgiz
The Irgiz rises on the eastern slopes of the Mugodzhar Hills and flows south through the Kazakh steppe. Its chief tributary, the Chet Irgiz, joins it from the west, and the river eventually meets the Turgay. Their waters belong to an inland drainage basin of lakes and marshes rather than reaching the sea. The valley marks a winding course through a broad, dry landscape of plains and low hills.
