On July 29, 2001, NASA's Landsat 7 satellite took this picture of Tengiz and Korgaljinski Lakes. Lake Tengiz dominates this image, a nearly uniform patch of blue-green outlined by off-white. The lake's pale lining indicates that its water level has dropped, exposing now-dry shoreline. East of Lake Tengiz, but connected to it via meandering waterways, are the Korgaljinski Lakes. Three large patches of pale blue-green, resembling the hue of Lake Tengiz, lie at the northern end of this marshy area. To the south, smaller water bodies mix with deep green vegetation. Looking like a delicate thread of deep blue, the Nura River appears to the east of these lakes. From the south, the Zhaksy-Kon also feeds this wetland network. Lush green vegetation in this area contrasts sharply with the otherwise arid landscape. Tengiz and Korgaljinski Lakes are a nesting site for more than 100 other bird species, and more than 300 bird species live on or around the lakes at various times of year. Home to hundreds of plant and bird species, and dozens of mammal species, the area has been designated a Ramsar wetland site.
