Aswan High Dam and Merowe High Dam, in Egypt and Sudan
Two large hydroeletrical projects have created expansive lakes in Egypt and Sudan. Just above the center of the image is Lake Nasser, is a vast reservoir in southern Egypt and northern Sudan, created by the Aswan High Dam across the waters of the Nile.
The smaller lakes visible to the west of Lake Nasser are the Toshka Lakes, also created by the Aswan High Dam, although somewhat indirectly, as their waters come from drainage carried to a depression in the Sahara Desert via canals from the larger Lake Nasser.
Further south is a light green reservoir created by the Merowe High Dam, a large construction project in northern Sudan, about 350 km north of the capital Khartoum. Merowe is a city about 40 km downstream from the construction site at Hamdab.
Also known as Merowe Multi-Purpose Hydro Project or Hamdab Dam, it is situated on the river Nile, close to the 4th Cataract where the river divides into multiple smaller branches with large islands in between.
The main purpose of the dam will be the generation of electricity. Its dimensions make it the largest contemporary hydropower project in Africa.
