Notes

  • The Cauvery Water Management Authority (CWMA) is the primary regulatory body overseeing water sharing between Karnataka and Tamil Nadu.
  • The CWMA upheld a recommendation from the Cauvery Water Regulation Committee (CWRC) for Karnataka to ensure a flow of 9,000 cusecs of water to Tamil Nadu for a 15-day period.
  • Karnataka reported compliance with the CWMA order, noting that water flow exceeded 11,000 cusecs as of Monday morning.
  • Tamil Nadu filed an application in the Supreme Court seeking the release of 17.604 tmc ft of water, citing an accumulated shortfall based on a pro-rata formula.
  • The Supreme Court clarified that any request for water exceeding the CWMA's directed amount must be challenged through the appropriate legal forum.
  • The matter remains sub-judice with the next hearing scheduled for September 15.
