Environmental issues in Egypt dam 98% of that sediment fell under the dam. 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. The importance of water resources for Egyptians has contributed to the creation of agencies, such as the Egyptian Ministry of State for Environmental Affairs, that promote and protect Egypt's natural resources.

Aswan Low Dam in the lower Nile. The dam, originally limited in height by conservation concerns, worked as designed, but provided inadequate storage capacity for planned development and was raised twice, between 1907 and 1912 and again in 1929–1933. These heightenings still did not meet irrigation demands and in 1946 it was nearly over-topped in an effort to maximize pool elevation. This led to the investigation and construction of the Aswan High Dam upstream. The earliest recorded attempt to build a dam near Aswan was in the 11th century, when the Arab polymath and engineer Ibn al-Haytham (known as "Alhazen" in the West)
