Lake Nasser ( , ) is a vast reservoir in southern Egypt and northern Sudan. It is one of the largest man-made lakes in the world. Before construction, Sudan was against the building of Lake Nasser, because it would encroach on land in the northern part of the country, where many Nubian people lived who would have to be resettled. In the end Sudan's land near the area of Lake Nasser was mostly flooded by the lake. Strictly speaking, "Lake Nasser" refers only to the much larger portion of the lake that is in Egyptian territory (83% of the total), with the Sudanese preferring to call their smaller body of water Lake Nubia ( , ). Description The lake is some long and across at its widest point, which is near the Tropic of Cancer. It covers a total surface area of and has a storage capacity of some of water. The lake was created as a result of the construction of the Aswan High Dam across the waters of the Nile between 1958 and 1970. The lake is named after Gamal Abdel Nasser, one of the leaders of the Egyptian Revolution of 1952, and the second President of Egypt, who initiated the High Dam project. It was President Anwar Sadat who inaugurated the lake and dam in 1971. Current issues Egypt lacks the water it needs for agriculture and electricity. The Grand Ethiopian Renaissance Dam, currently being constructed in Ethiopia, has caused tensions between Egypt and Sudan and Ethiopia. Egypt is worried that the new dam will stop the Nile River from adequately filling Lake Nasser. The water supply of Lake Nasser produces electricity, and there is concern that diminishing water flowing into Lake Nasser will adversely affect the Aswan Dam's ability to generate electricity. There are pumping stations that control the water going into Lake Nasser, and currently this project generates 10 billion kilowatt-hours of hydroelectric power each year to Egyptians. Sport and tourism Fishing for Nile perch, from both on the shore and from boats, is popular. Before Lake Nasser was filled, as part of the International Campaign to Save the Monuments of Nubia, many ancient Egyptian sites were physically relocated to new locations above the lake's high water level. However, some were not relocated, such as part of the massive fortress of Buhen, which is now underwater. The relocation of the temples at Abu Simbel, one
