The Cauvery Water Regulation Committee (CWRC) compared the net inflow of Karnataka's four reservoirs with 30‑year data, finding a 60% shortfall, and ordered a release of 3,500 cusecs for 15 days to Tamil Nadu. The decision carries significant implications for both states.

Key Takeaways

  • CWRC ordered Karnataka to release 3,500 cusecs daily for 15 days.
  • Four Karnataka reservoirs are facing a 60% water shortfall.
  • Tamil Nadu will receive roughly 4.5 tmc ft of water.

Background of the Decision

On July 28, 2026, the Cauvery Water Regulation Committee met in Delhi and instructed Karnataka to release 3,500 cubic feet per second (cusecs) to Tamil Nadu for the next 15 days, starting July 29. If sustained, this flow translates to about 4.5 thousand million cubic feet (tmc ft) for Tamil Nadu.

The CWRC operates under the Cauvery Water Management Authority (CWMA), which implements the 2007 final award of the Cauvery Water Disputes Tribunal, as amended by the Supreme Court in 2018. The committee includes the CWMA Water Resources Member, chief engineers of all basin states, and representatives from the India Meteorological Department, Central Water Commission, and the Union Ministry of Agriculture.

Historical Background

The Cauvery dispute dates back to the 1990s, featuring multiple tribunals and court rulings. In 2018, the Ministry of Jal Shakti issued a notification mandating daily monitoring of water levels, inflows, and storage across eight reservoirs in Karnataka, Tamil Nadu, and Kerala. Past drought periods have seen emergency relief measures and inter‑state negotiations.

Why This Matters

BozokMedia analysis shows that the current release decision reflects a delicate balance between hydrological scarcity and political pressure, setting a precedent for future inter‑state water negotiations in India.

"Sustainable Cauvery water management requires a cooperative sharing formula that benefits both riparian states," says water‑resource expert Dr. Anita Sharma.
