Built in the 1960s, completed in 1970, and formally inaugurated in 1971.The Aswan High Dam was an engineering marvel at the time and changed the face of Egypt. It increased the cultivable land by 30% and doubled Egypt’s available electricity supply. It also created Lake Nasser, at the time the world’s largest artificial lake, which would have covered the important Abu Simbel Temple monuments if not for the support of UNESCO and a worldwide appeal for funds to move them to higher ground, a massive feat which was successfully achieved.
The Aswan High Dam yields enormous benefits to the economy of Egypt. For the first time in history, the annual Nile flood can be controlled by man. The dam impounds the floodwaters, releasing them when needed to maximize their utility on irrigated land, to water hundreds of thousands of new acres, to improve navigation both above and below Aswān, and to generate enormous amounts of electric power.
