This is an image taken
by the Advanced Spaceborne Thermal Emission and Reflection Radiometer
(ASTER) satellite. It shows a 60 km stretch of the Yangtze River just
west of the Three Gorges Dam. The upper image was acquired on May 20,
2001 before the dam was filled. The bottom image is from March 25,
2003, showing the partial filling of the reservoir.
When the Three Gorges reservoir will be
completely filled in 2012, the lake will be some 600 km in length and
submerge about 17,160 ha of farmland and some 200 ancient tombs.
