An international pact known as the Indus Waters Treaty was negotiated in 1960 between India and Pakistan under World Bank mediation.
To avoid disagreements over water use, it was designed to control how river flows were divided between the two nations.
Specifics of the Treaty 1. River division
Six significant rivers were divided into two groups under the pact.
Eastern Rivers: Ravi, Beas, and Sutlej
India was given complete authority over these rivers.
Rivers in the West: Chenab, Jhelum, and Indus
The pact gave Pakistan access to these rivers’ water resources, but it also permitted India to carry out some projects, such as the construction of hydropower, but not irrigation.
