India is seeking changes in a six-decade-old Indus water treaty and has formally notified Pakistan to amend the pact. The longstanding dispute concerning the Kishanganga and Ratle hydroelectric projects has prompted India to seek a modification in the treaty.

Under the Indus Water Treaty, India was granted unrestricted access to the water from the ‘Eastern Rivers’, and Pakistan retained rights to that from the ‘Western Rivers'.

The Indus Waters Treaty, brokered in 1960, allocates water from six rivers between the two nations. Under the treaty India controls the water from the Beas, Ravi, and Sutlej (eastern rivers), while Pakistan has rights over the Chenab, Indus, and Jhelum (western rivers).
