Background
At the time of independence, the boundary line between the two newly created independent countries i.e. Pakistan and India was drawn right across the Indus Basin, leaving Pakistan as the lower riparian. Moreover, two important irrigation head works, one at Madhopur on Ravi River and the other at Ferozepur on Sutlej River, on which the irrigation canal supplies in Punjab (Pakistan) had been completely dependent, were left in the Indian Territory. A dispute thus arose between two countries regarding the utilization of irrigation water from existing facilities. Negotiations held under the good offices of International Bank for Reconstruction and Development (World Bank), culminated in the signing of Indus Waters Treaty in 1960. The Treaty was signed at Karachi by Field Marshal Mohammad Ayub Khan, the then President of Pakistan, Shri Jawaharlal Nehru, the then Indian Prime Minister and Mr. W.A.B. Illif of the World Bank on 19th September, 1960. The Treaty however is effective from1st April, 1960 (Effective Date).
