Why it matters
Water disputes between Indian states are critical issues that impact agriculture, urban water supply, and regional political stability.
The story so far: The eight-year-old Cauvery Water Management Authority (CWMA) is holding its 53rd meeting in New Delhi on Wednesday (July 22, 2026) amid an extremely poor southwest monsoon (June-September) in many parts of southern States, especially catchment of the Cauvery river. The two principal riparian States — Karnataka and Tamil Nadu — are expected to present their point forcefully at tomorrow’s meeting, as they have been reeling under the impact of an adverse monsoon.
Established on June 1, 2018, the Authority was constituted as an implementation mechanism for the Supreme Court’s (SC) 2018 judgment and the final award of the Cauvery Water Disputes Tribunal (CWDT) of 2007. The key aspect of the judgment pertains to water allocation among the constituents of the Cauvery basin.
