Do you know what was the population at that time? How many indistries existed? How much was being exported? West Pakistan population was less than East Pakistan's. Go and open history books. Aboout two dams, repeatedly fourth and fifth tunnel repairs forced to run the Tarbela dam at lower than peak capacity. The then Secretary of Irrigation and Power West Pakistan (Sher Mohammad Balaoch a top student and gold madelist graduate from NED Engineering College Karachi of 1943 batch. NED at that time was affiliated with Bombay University) was deadly against this project. He suggested different site due to soil and carrying capacity of water problem. Secretary was sacked by Ayub as he had already made deal with the contractors. Tarbela never produced electricity it was designed for and it has become now white elephant. Do you know how much is being spent on repairs of these tunnels every year? If these tunnels are not repaired the whole dam would have collapsed long time ago.
burqapostX if you don't know the history ask some one who has knowledge about these dams. Again I say that Ayub Khan at that time was considered as richest President of poor country. He had 80 croores in Swiss bank at that time. He was fed by big businesses regualry to import machinery without paying the taxes to government.
