The treaty finds its roots in the 1947–48 war, also known as the first Kashmir war, when India restricted water flow to Pakistan on April 1, 1948, for the first and only time, leading to severe shortages in Pakistan. This sudden move caused panic and water shortages in Pakistan’s Punjab region where farmers relied on the river water for crop irrigation. Both countries signed a short-term Inter-Dominion Accord on May 4, 1948, that required India to restore the water flow in return for annual payments. Eventually they signed the IWT on September 19,1960 with mediation from the World Bank. The agreement assigned the eastern rivers—Ravi, Beas and Sutlej—to India while the western rivers—Jhelum, Chenab and Indus — were given to Pakistan. However, concerns about water security had already taken deep root in Pakistan.
