Lakes Zaysan and Markakol, Kazakhstan – September 21st, 200947.9N 83.8E
Lake Zaysan is a freshwater lake in eastern Kazakhstan, in a hollow between the Altai and Tarbagatai Mountains, at an altitude of 420 m. The lake is 105 km long and 22 to 48 km wide, with a surface area of 1,810 km² (700 mi²). Its maximum depth is 15 m.
Lake Zaysan’s major tributaries are the Kara-Irtysh (Black Irtysh) and Kendyrlyk from the east. Here it appears brownish green from the inflow of sediments from those rivers. Its only outlet is the Irtysh River (or White Irtysh).
Another body of water, Lake Markakol, is visible below the snow-capped mountains in the upper right corner. It is fed by small rivers and streams.
