The High Dam has also improved the efficiency and the extension of the Old Aswan Hydropower stations by regulating upstream flows. [31] At the time of completion, it was the largest power station in Africa and the 6th largest hydroelectric power station in the world. All High Dam power facilities were completed ahead of schedule.
Environmentally, the Aswan Dam has contributed to numerous issues for Egyptians. The expansion of desert areas since the Aswan High Dam's construction in 1970 has increased in soil salinity which allowed for waterborne diseases to emerge. In 1994, 28% of Egypt's soils were damaged by significant levels of salinity. [3]
Lake Nasser behind the Aswan High Dam. The history of modern water management in Egypt begins with the construction of the Old Aswan Dam in 1902 and barrages on the Nile in the 19th and early 20th century. The Old Aswan Dam partially stored the waters of the Nile to allow the growing of multiple crops per year in the Nile Delta, while the ...
[20] [21] [22] An example is the effect of the construction of the Aswan High dam in Egypt, where the drop in nutrient concentration to the Nile delta impeded the diatom blooms causing a substantial decrease the fish population of Sardinella aurita and Sardinella eba, while the reduced load of mud and silt affected the micro-benthic fauna ...
The project would provide 75 million acre-feet (93 km 3) of water to water-deficient areas in the North American continent, [7] including Canada and the United States, as well as irrigation water for Mexico, which Parsons claimed would receive enough water to reclaim 7 or 8 times more land than Egypt reclaimed with the Aswan High Dam.

First in 1902 due to the construction of the Aswan Lower Dam, then in both 1912 and 1933 due to the rising water levels, and a fourth time after the creation of the Aswan High Dam. The forced relocation stripped many native Nubians of their ancestral homelands, with the compensation of unsuitable homes for living and agriculture.
Today the Aswan High Dam obstructs most of this sediment, now retained in Lake Nasser. The reduction in annual silt deposits has contributed to rising water tables and increasing soil salinity in the Delta, the erosion of the river's banks in Upper Egypt, and the erosion of the alluvial fan along the shore of the Mediterranean Sea.
Rivalling the Aswan High Dam in scope, the intention is to develop the hydroelectric potential of the Qattara Depression by creating an artificial lake. [1] The Qattara depression is a region that lies 60 m (200 ft) below sea level on average and is currently a vast, uninhabited desert.
