Nicknamed Dragon Lake, this body of water is formed by the Bratskove Reservoir,
built along the Angara river in southern Siberia, near the city of Bratsk. This image was
acquired in winter, when the lake is frozen.
This image was acquired by
Landsat 7s Enhanced Thematic Mapper plus
(ETM+) sensor on December 19, 1999. This is a natural color composite image made using blue, green, and red wavelengths.
Meltwater from glaciers to the east and west drains into Lake Morari, a large lake that lies at an altitude of 4,521 meters (14,830 feet) on the Tibetan Plateau. A stream on the west side provides the lake’s main inflow. Mud from this river gives the light blue hues to the lake water. The well-formed alluvial fan (image center), built by sediment from the main inflow river, is the reason the lake has formed at this point in the valley.
