After the successful construction and launching of the giant Tarbela and Mangla dams, the nation enjoyed the fruits in the form of irrigation of vast areas of dry land and use of cheap electricity. But owing to political and economic disturbances, instability (absence of firmness and continuity) of governments and the illiteracy of our masses the erection of other big dams across our rivers could not be undertaken (taken up).
The Kala Bagh dam is proposed to be built across the Indus about 120 miles southwest of Islamabad, some 16 miles from the Soan River, The height of the dam is proposed to be 259 feet while the height of Nowsher and surrounding areas is more. So, according to several experts, there will not be any danger of the dam water overflowing into the surroundings. (Though of course the danger of the dam water logging or causing the water level under the earth to-rise considerably cannot be ruled out.) Some critics say that the dam may cause floods by the overflow of water in the rainy season. However, other critics say that floods have been around without the dam being in existence.
The Kalabagh dam, according to the plans, will have much greater height and its lake will cover an area of 164 square miles. As a multi-purpose project it will, firstly, provide cheap hydroelectric power (electricity produced from water energy). Joined with the Tarbela Dam resources, the two dams will generate (produce) tremendous electricity for industrial, commercial and domestic purposes. Thermal power production (that is, with coal, gas and oil) will not be needed and the imports of oil for this purpose. will almost end, and the country will be able to save sizeable foreign exchange.
Another main objection to the Kalabagh dam construction is from certain politicians who say that it will result in the availability of less water in Sindh as more will be utilized by the Punjab. This objection is met by others who say that already in 1991 the Indus river water has been apportioned between the provinces through an accord (agreement), and Sindh will continue to receive its settled share of water.
