Decreasing Water Levels in Egypt’s Toshka Lakes

Nearly six years of regional drought and rapidly increasing demand for water have resulted in decreasing water levels in lakes throughout East Africa. The flooded regions of the Toshka Lakes west of Lake Nasser have decreased greatly over the years, exposing the former dune fields, and leaving a “bath-tub ring” of wetlands (dark region) surrounding the lake shorelines.

Astronaut photograph ISS012-E-11639 was acquired December 11, 2005, with a Kodak 760C digital camera using an 180 mm lens, and is provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Group, Johnson Space Center. The earlier image, STS102-716-25, was taken from the Space Shuttle on March 15, 2001 using a Hasselblad film camera equipped with a 250 mm lens. The International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth.
