This northeast-looking view shows the Ataturk Reservoir and Dam, presently the largest man-made lake in Turkey. Located in south central Turkey on the Euphrates River, Ataturk Reservoir was completed in the early 1990's. The meandering Euphrates River (dark line) can be seen exiting the scene below the left center of the image. Smooth lake waters appear as dark blue, while wind-roughened waters appear light blue. The light area to the west of the dam (left center) is where rocks were quarried for the construction of the dam. Photo courtesy of NASA.
