Egypt’s Lake Nasser is one of the world’s largest man-made lakes, stretching over 300 miles long and 10 miles wide. This time series shows Landsat’s view of Lake Nasser’s transformation between 1972 and 2024, during which the lake’s water levels fluctuate dramatically due to the region’s arid climate and seasonal rainfall. High evaporation rates in the dry season can cause the lake to shrink, while flooding seasons can bring the water levels to a high point.
