Well, our 4 day boat ride has come to an end at the Aswan High Dam and Lake Nasser.

Gamel Abdel Nasser's vision of a modern Egypt rose and fell on the construction of the dam, which began in 1960. It took Soviet financing, plus the sweat of 30,000 Egyptians working around the clock, to complete the work by 1971.

Lake Nasser is one of the world's largest man-made lake, 310 mi long— 93 mi of which is in Sudan—and it has a storage capacity of 210,000 billion cubic yards of water. The dam doubled Egypt's power-generating capabilities, and it ensures a net surplus of 26 billion cubic yards of water as a reserve against low annual floods upriver.

The disadvantages of damming the Nile included the loss of fertile silt that the floods brought, which has made the use of chemical fertilizers a necessity. An incalculable loss is Nubia, which now lies beneath so many cubic yards of water that its 100,000 inhabitants relocated along the river valley. As one Nubian elder put it, "we cut off the arm to save the body." The Temple is Isis world have been flooded as well but it was dissembled, block by block and moved to higher ground.  You can still see some of the engineering markings on the blocks that were used to reassemble this beautiful temple.
