DMK Moves Supreme Court for Immediate Cauvery Water Release by Karnataka
UPSC / SSC current affairs note · Polity
Why in news
The DMK has moved the Supreme Court seeking a direction to Karnataka to release Cauvery water to Tamil Nadu, citing an urgent water crisis in the Cauvery Delta. This comes after Karnataka challenged the CWRC's order before the CWMA, which dismissed the appeal. The move highlights ongoing inter-state water dispute and the critical need for water during the agricultural season.
Background
The Cauvery water dispute is a long-standing inter-state river water dispute between Karnataka and Tamil Nadu, with the Cauvery Water Disputes Tribunal and later the Supreme Court adjudicating on water sharing. The Cauvery Water Management Authority (CWMA) and Cauvery Water Regulation Committee (CWRC) were constituted to implement the final award.
Key facts
DMK moved the Supreme Court on Saturday (August 2, 2026) seeking direction to Karnataka to release Cauvery water to Tamil Nadu.
The application was filed by DMK Farmers Wing secretary and former MP A.K.S. Vijayan.
The DMK argued that the present period is the most crucial period of the entire water year for the Cauvery Delta.
Water is needed for raising the Kuruvai (short-term) paddy crop and for preparatory and transplantation operations for the Samba (long-term) crop.
The application sought compliance with the CWRC's July 28 direction to release 3,500 cusecs of water per day at Biligundlu for 15 days from July 29.
Karnataka had challenged the CWRC order before the CWMA, but its appeal was dismissed on July 30.
The application was settled by senior advocate P Wilson.
Tamil Nadu had informed the CWRC that Karnataka was not releasing water as directed.
The DMK warned that if water is not released, the standing Kuruvai crop will wither, and Samba cultivation will be imperilled, turning the Cauvery Delta into a desert.
