In 1990, the central government created a tribunal to examine the Cauvery river water sharing dispute between Karnataka and Tamil Nadu.
— In 2007, this tribunal delivered its verdict on how water should be shared between Tamil Nadu, Karnataka, Puducherry and Kerala. However, the states have challenged the divide.
— In Karnataka, there are four dams on the Cauvery. The state government says there isn’t enough supply in these dams for the drinking water needs of cities like Bengaluru and Mysuru.
— The last time the Supreme Court intervened to order Karnataka to increase the supply of water to Tamil Nadu was in 2012.
— On September 8, 2016 Supreme Court ruled that Karnataka must release 15,000 cusecs of water daily for the next 10 days to Tamil Nadu – that’s nearly twice what Karnataka is currently sharing with its neighbour.
