In its response, Karnataka has pointed to the Indus Waters Treaty and international practice to say that inter-State water allocations can be revisited by agreement or adjudication when circumstances change.

Tamil Nadu has recorded its lowest Cauvery realisation in 14 years, and paddy coverage in the delta is almost one lakh acres lower than last year.

The Supreme Court's 2018 verdict raised Karnataka's share by 14.75 TMC over the tribunal award, and the Cauvery Water Management Authority was set up that year.

How the exam will ask it

ಪ್ರಿಲಿಮ್ಸ್

  • The Supreme Court's 2018 verdict on the Cauvery dispute increased Karnataka's share compared with the tribunal award.
  • The Cauvery Water Management Authority was constituted in 2018 following the Supreme Court's verdict.
  • Cauvery is an inter-State river dispute involving Karnataka and Tamil Nadu among the riparian States.

ಮೇನ್ಸ್

GS2 (Polity and Federalism): Inter-State water disputes arise when shares fixed by tribunals meet changing rainfall and demand. The Inter-State River Water Disputes Act, the 2018 Supreme Court verdict and the CWMA provide the framework, while Karnataka's call to revisit allocations tests the finality of awards. The way forward lies in data-driven distress-sharing formulas, efficient water use and cooperative federal mechanisms rather than repeated litigation.
