Lake Nasser Dam, also known as the ASWAN Dam, is a rock-fill dam located on the Nile River in Egypt. It was built between 1960 and 1970 and is one of the largest dams in the world. The dam created Lake Nasser, a reservoir that stretches from southern Egypt to northern Sudan. The dam was built to provide hydroelectric power, irrigation, and flood control for the region. It has also helped to reduce the risk of drought in the area.
