Lake Nasser
Template:Short description Template:Use dmy dates Template:Infobox body of water
Lake Nasser (Template:Langx Template:Transliteration, Template:IPA) is a large reservoir in southern Egypt and northern Sudan. It was created by the construction of the Aswan High Dam and is one of the largest man-made lakes in the world.<ref>Template:Cite web</ref> Before its creation, the project faced opposition from Sudan as it would encroach on land in the northern part of the country, where many Nubian people lived who would have to be resettled.<ref name="ResettlingNubians">Template:Cite book</ref><ref>Template:Cite book</ref> In the end Sudan's land near the area of Lake Nasser was mostly flooded by the lake.<ref>Template:Cite web</ref> The lake has become an important economic resource in Egypt, improving agriculture and touting robust fishing and tourism industries.
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 (Template:Langx Template:Transliteration, Template:IPA).<ref>Template:Cite book</ref>
Physical characteristics
The lake is some Template:Cvt long and Template:Cvt across at its widest point, which is near the Tropic of Cancer. It covers a total surface area of Template:Cvt and has a storage capacity of some Template:Cvt of water.<ref>Template:Cite journal</ref>
History
Before the Aswan High Dam and Lake Nasser
Before the construction of the Aswan High Dam and the consequent creation of the Lake Nasser, the area that the lake now occupies was a significant part of the region of Nubia, home to several pharaohs of Egypt and empires such as that of the Kush.<ref>Template:Cite web</ref>
Construction of the Aswan High Dam 1960–1970
The construction of the Aswan High Dam began in 1960 at the behest of Lake Nasser's namesake and the second president of Egypt, Gamal Abdel Nasser. It was President Anwar Sadat who inaugurated the lake and dam in 1971.<ref>Template:Cite book</ref> Finished in 1970, the Aswan High Dam across the Nile was built to replace the insufficient Aswan Low Dam built in 1902. The goals of the High Dam and the reservoir it created, Lake Nasser, were to create a more stable source of water, to increase agricultural production, and to produce electricity for Egypt.<ref>Template:Cite web</ref>
Controversies
The construction of the Aswan High Dam and Nasser Lake was host to several controversies related to its effects on the environment and those living in the affected area.
Displacement of Nubians
As a result of the construction of Aswan High Dam and the subsequent filling of Nasser Lake, tens of thousands of native Nubians were forced to relocate from their homes and migrate elsewhere.<ref>Template:Cite journal</ref> Though some have been able to resettle on the shores of the new lake, their original homes have been flooded and lost to the lake.
Flooding of ancient ruins and monuments
The construction of the Aswan High Dam and Nasser Lake sparked an international movement to preserve the history of the region. Due to the filling of the new Lake Nasser, much of the region would be flooded and as such, the ancient monuments and artifacts that lay there would have been lost. Due to this, an international effort was made to rescue and relocate many of the ancient sites and artifacts that were threatened which culminated in the International Campaign to Save the Monuments of Nubia led by UNESCO.<ref>Template:Cite journal</ref> Though a great many sites were saved and relocated such as the temples of Kalabsha, Wadi es-Sebua, and Amada, some sites such as the fortress of Buhen were unable to be rescued and now rest underwater in the lake.<ref>Template:Cite book</ref> The most famous of those that were rescued were temples at Abu Simbel which were broken down and relocated safely off the coast of Lake Nasser.<ref>Template:Cite web</ref><ref>Template:Cite news</ref>
Ecological ramifications
The damming of the Nile has come with several ecological consequences as the natural flow and processes of the river have been interrupted. One effect has been the interruption of the flow of sediments downstream of the dam, which since ancient times had provided many of the needed nutrients for agriculture downstream. Consequently, Egyptian farmers have been forced to resort to mineral fertilizers to maintain arable land for growing crops. The habitat of several native animal species past Lake Nasser and the Aswan High Dam, such as that of the Nile crocodile, have also been greatly affected as the reduction of water levels that came with the construction of the dam rendered these habitats uninhabitable.<ref>Template:Cite book</ref>
Economic impacts
By providing a reliable source of water for irrigation and agriculture year-round instead of the seasonal and unpredictable floods of the Nile River, Lake Nasser has provided a large boon to the agricultural industry of the Egyptian economy. The agricultural industry employs about 25% of Egypt's population. With the creation of a more stable water supply in Lake Nasser, Egypt's arable land increased by about 30%.<ref>Template:Cite web</ref>
Being home to 52 different species of fish which are dominated by several different species of tilapia which make up the vast majority of catches,<ref>Template:Cite book</ref> as well as the popular Nile perch, Lake Nasser has developed a robust fishing industry with thousands of fishing boats sailing the lake and fish processing facilities dotting its shores.<ref>Template:Cite book</ref>
Lake Nasser has become a popular tourist destination for recreational fishing, sightseeing cruises, and the many relocated monuments saved from the initial filling of Lake Nasser, especially examples such as the Abu Simbel temples.<ref>Template:Cite news</ref>
The Aswan High Dam which holds Lake Nasser produces about 2.1 gigawatts of hydroelectricity, providing a significant percentage of Egypt's electricity needs (up to half when it was completed in 1970).<ref>Template:Cite web</ref>
Current and future issues
Grand Ethiopian Renaissance Dam
With the beginning of construction of the Grand Ethiopian Renaissance Dam (GERD) in 2011, Egypt faces the threat of water shortage as the new upstream dam would reduce the amount of water flowing downstream to Lake Nasser. As this flow of water from the Nile into Egypt and Sudan constitutes a major part in their economy, its reduction due to the construction of the GERD could potentially be devastating for the nations. The project was about 90% completed by 2023; staged filling of the reservoir began in 2020. The GERD has already begun affecting Egypt as it has reduced the flow of water down the Nile River and decreased available agricultural land for the country.<ref>Template:Cite web</ref> If Egypt, Sudan, and Ethiopia are unable to come together to work out possible solutions or compromises for this water problem, the GERD could possibly pose an existential threat to Lake Nasser and could have a great destabilizing effect on Egypt and Sudan who rely on it so greatly in many sectors of the economy.<ref>Template:Cite report</ref>
