Present status of the project:

  • The ₹9,000 crore project was approved by Karnataka State government in 2017.
  • It has received approval from the Union Water Resources Ministry for the detailed project report and is awaiting approval from the Ministry of Environment and Forests (MOEF).
  • However, Tamil Nadu has approached the Supreme Court against the project.

About Mekedatu dispute:

Mekedatu is a location along Cauvery in Kanakapura Taluk of Ramanagara District of Karnataka.

Karnataka wants a reservoir across Cauvery at Mekedatu, to meet Bengaluru’s water problem.

What Tamil Nadu says?

Tamil Nadu objected saying Karnataka had not sought prior permission for the project.

Its argument was that the project would affect the flow of Cauvery water to Tamil Nadu.

Tamil Nadu also argues that the reservoir violates the decisions of the Supreme Court and the Cauvery Tribunal.

  • The Supreme Court had noted that the existing storage in the Cauvery basin of Karnataka should be taken into account for ensuring water releases to Tamil Nadu during the period of June to January.
