The Aswan Dam Monica Crawford & Meghan Moloney
Location • The Aswan Dam is located across the Nile River in Egypt. • It forms the reservoir Lake Nasser.
DATE started: 1960 completed: July 21, 1970 • The Aswan Dam has been operating since 1970 and is still functioning today. • It continues to affect the people and farmland downstream.
Effects of the Aswan Dam • The dam affects the Nile River, which is one of the largest rivers in Egypt. • Every year, the Nile River would overflow its banks. This overflowing caused a large amount of silt to be brought into the dry areas surrounding the river. This silt acted as a natural fertilizer for the land. • The river did not always collect enough water in order for the banks to overflow, and the surrounding area would remain too dry to produce crops. • The dam was built to collect the rainwater and then release the water during the dry season.
Aswan Dam: Pros • A stable source of water for Egypt has been secured due to the Aswan Dam. • The Aswan Dam has allowed for the production of many irrigation systems in Egypt, which has allowed for farmers to produce more crops and boost the economy in Egypt. • The Aswan Dam is also used to produce electrical energy for much of Egypt.

Aswan Dam: Cons • Thousands of poor Egyptians were forced to move their homes and families so that the massive dam could be built. • The construction of the dam stopped the annual flooding that used to deposit silt to the areas surrounding the Nile River. • The Aswan Dam has caused all of the silt that acted as a natural fertilizer to stay trapped at the bottom of Lake Nasser. • This has required the importation of many chemical fertilizers to the area so that the crops may prosper. • These chemical fertilizers are much more harmful to the environment than the silt that used to be deposited from the annual flood.

Future Impact of the Aswan Dam • Because the Aswan Dam has stopped silt from being deposited downstream the Nile River Delta has started to experience great amounts of erosion. • This has caused the soil of the Nile River Delta to become compact and could eventually lead to the sinking of the Nile River Delta.
