This image of crescent-shaped Lake Balkhash was taken by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS)
on April 27, 2000. Lake Balkhash is located in eastern Kazakhstan, north of the Tian-Shan mountains. The Ili River
flows into the western end of the lake, filling it with bright sediment. This sediment highlights the difference
between the freshwater western side of the lake and the saline eastern side. A sandbar prevents mixing between
the lakes two sections.
Other features in this image include Lake Sayram in the lower right (southeast) corner, which is surrounded by the
Borohoro Shan mountain range. At center right, just north of the Borohoro Shan, are lakes Sasykkol (left) and Alakol
(right). The Karatal River flows northward through an arid and sandy landscape into the center of Lake Balkhash.
The full-size image compares the region on April 27th
image with one from the 18th. In that time sediments in lakes Balkhash and Sasykol increased noticeably, probably
due to snowmeltnote the decrease in snowcover on the regions mountains. Also, the ice on Lake Sayram melted.
These images were retrieved by the SeaWiFS high-resolution ground station in Mongolia, which recently began sending data to Goddard Space Flight Center.

Lake Teletskoye, one of Siberia’s prime tourist destinations, is a large lake that is nestled in a narrow valley between the snow-capped Al-tyntu (west, at top) and Korbu (east, at bottom) mountain ridges of the Altai Mountains. The lake is nearly 80 kilometers long by 5 kilometers wide and 325 meters deep; it is one of the deepest lakes in the world. But Lake Teletskoye is more than a large, deep lake. It is located within the 9,000 km² Altaisky Zapovednik nature reserve, which helps protect its unspoiled waters.
At the juncture of the border between China and Russia sits Lake Khanka, also known as Lake Xinghai. Due to their importance to plant and animal species, the lake and the surrounding wetlands are protected by the Ramsar Convention, an international treaty for the protection and sustainable use of wetlands. Migratory birds that frequent this lake include several endangered species, such as the Japanese crane.
