How did the Aswan high dam change Egyptian farming?

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 (the dam’s 12 turbines can generate 10 billion kilowatt-hours annually). The reservoir, which has a depth of 300 feet (90 metres) and averages 14 miles (22 km) in width, supports a fishing industry.
