The Indus System of Rivers comprises the three Western Rivers in the Indus, the Jhelum and Chenab together with three Eastern Rivers; the Sutlej, the Beas and the Ravi. To establish the ownership of these waters, an Indus Water Treaty was signed between India and Pakistan on 1 April 1960, under monitoring of the World Bank. The treaty, under Article 5.1, envisages the sharing of waters of the rivers Ravi, Beas, Sutlej, Jhelum and Chenab which join the Indus River on its left bank (eastern side) in Pakistan. According to this treaty, Ravi, Beas and Sutlej, which constitute the eastern rivers, are allocated for exclusive use by India before they enter Pakistan. However, a transition period of 10 years was permitted in which India was bound to supply water to Pakistan from these rivers until Pakistan was able to build the canal system for utilisation of waters of Jhelum, Chenab and the Indus itself, allocated to it under the treaty. Similarly, Pakistan has exclusive use of the Western Rivers Jhelum, Chenab and Indus but with some stipulations for development of projects on these rivers in India. Pakistan also received one-time financial compensation for the loss of water from the Eastern rivers. Since 31 March 1970, after the 10-year moratorium, India has secured full rights for use of the waters of the three rivers allocated to it. The treaty resulted in partitioning of the rivers rather than sharing of their waters.
