Lake Nasser

Lake Nasser (Arabic: بحيرة ناصر‎ Boħēret Nāṣer, Egyptian Arabic: [boˈħeːɾet ˈnɑːsˤeɾ]) is a vast reservoir in southern Egypt and northern Sudan. It is one of the largest man-made lakes in the world.

Strictly, "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 (Egyptian Arabic: بحيرة النوبة Boħēret Nubeyya, [boˈħeːɾet nʊˈbejjæ]). The area of Sudan-administered Wadi Halfa Salient was largely flooded by Lake Nasser.

Description

The lake is some 550 km (340 mi) long and 35 km (22 mi) across at its widest point, which is near the Tropic of Cancer. It covers a total surface area of 5,250 km² (2,030 sq mi) and has a storage capacity of some 132 km³ (32 cu mi) 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 1971. 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.

Gamal Abdel Nasser

Gamal Abdel Nasser Hussein (Arabic: جمال عبد الناصر حسين‎, IPA: [ɡæˈmæːl ʕæbdenˈnɑːsˤeɾ ħeˈseːn]; 15 January 1918 – 28 September 1970) was the second President of Egypt, serving from 1956 until his death. Nasser led the 1952 overthrow of the monarchy and introduced far-reaching land reforms the following year. Following a 1954 attempt on his life by a Muslim Brotherhood member acting on his own, he cracked down on the organization, put President Muhammad Naguib under house arrest, and assumed executive office, officially becoming president in June 1956.

Nasser's nationalization of the Suez Canal and his emergence as the political victor from the subsequent Suez Crisis substantially elevated his popularity in Egypt and the Arab world. Calls for pan-Arab unity under his leadership increased, culminating with the formation of the United Arab Republic with Syria (1958–1961). In 1962, Nasser began a series of major socialist measures and modernization reforms in Egypt. Despite setbacks to his pan-Arabist cause, by 1963 Nasser's supporters gained power in several Arab countries and he became embroiled in the North Yemen Civil War. He began his second presidential term in March 1965 after his political opponents were banned from running. Following Egypt's defeat by Israel in the 1967 Six-Day War, Nasser resigned, but he returned to office after popular demonstrations called for his reinstatement. By 1968, Nasser had appointed himself prime minister, launched the War of Attrition to regain lost territory, began a process of depoliticizing the military, and issued a set of political liberalization reforms. After the conclusion of the 1970 Arab League summit, Nasser suffered a heart attack and died. His funeral in Cairo drew five million mourners and an outpouring of grief across the Arab world.

Lake

A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean (except for sea lochs in Scotland and Ireland), and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are usually flowing. However most lakes are fed and drained by rivers and streams.

Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them.

Many lakes are artificial and are constructed for industrial or agricultural use, for hydro-electric power generation or domestic water supply, or for aesthetic or recreational purposes.

Nile perch

The Nile perch (Lates niloticus) is a species of freshwater fish in family Latidae of order Perciformes. It is widespread throughout much of the Afrotropic ecozone, being native to the Congo, Nile, Senegal, Niger, and Lake Chad, Volta, Lake Turkana, and other river basins. It also occurs in the brackish waters of Lake Maryut in Egypt. Originally described as Labrus niloticus, among the marine wrasses, the species has also been referred to as Centropomus niloticus. Common names include African snook, Victoria perch (a misleading trade name, as the species is not native to Lake Victoria), and a large number of local names in various African languages, such as the Luo name mbuta or mputa. In Tanzania, it is called sangara, sankara or chenku. In Francophone African countries, it is known as capitaine and in Egypt/Sudan as am'kal. Its name in the Hausa language is giwan ruwa, meaning "water elephant".

Lates niloticus is silver in colour with a blue tinge. It has distinctive dark-black eyes, with a bright-yellow outer ring. One of the largest freshwater fish, it reaches a maximum length of nearly 2 m (more than 6 ft), weighing up to 200 kg (440 lb). Mature fish average 121–137 cm (48–54 in), although many fish are caught before they can grow this large.
