Lake Nasser, Egypt

A true-colour composite satellite image from the Lake Nasser/Nubia Lake that was artificially created by the Aswan High Dam. The Lake at the bottom right of the image shows a stark contrast with the red sand from the surrounding desert areas. Taken by Sentinel-2 in November 2017.

Lake Nasser is one of the largest man-made lakes in the world. The lake was created as a result of the construction of the Aswan High Dam across the waters of the Nile in 1970. The lake is named after Gamal Abdel Nasser, one of the leaders of the Egyptian Revolution of 1952, who initiated the High Dam project. The dam's ability to better control flooding, provide increased water storage for irrigation, and generate hydroelectricity was pivotal to Egypt's industrialization.

The high dam at Aswan releases, on average, 55 cubic kilometres (45,000,000 acre·ft) water per year, of which some 46 cubic kilometres (37,000,000 acre·ft) are diverted into the irrigation canals. Regulating the Nile's annual flooding and irrigating fields throughout the year almost doubled the agricultural yield for Egypt.

The lake crosses over the Egypt-Sudan border and, strictly speaking, Lake Nasser only refers to the portion of the lake in Egyptian territory, with the Sudanese referring to their portion of the lake as Lake Nubia. However, as the Ethiopian Renaissance Dam upstream approaches completion, it is likely parts of the Nasser/Nubia Lake will disappear.

The image was taken by Sentinel 2 (Copernicus program) in November 2017.
