Notes

  • The Cauvery Water Management Authority (CWMA) and Cauvery Water Regulation Committee (CWRC) are the primary bodies managing the inter-State water dispute.
  • The CWRC issued a direction on August 25 requiring Karnataka to release 9,000 cusecs of water daily for 15 days to Tamil Nadu, measured at the Biligundlu gauge.
  • The total volume of water mandated by the August 25 order is 11.66 tmc ft.
  • Karnataka has appealed to the CWMA for a reduction in the release volume from 9,000 cusecs to 2,000 cusecs.
  • Karnataka cites severe hydrological distress, noting that cumulative inflows into its four Cauvery basin reservoirs are 49.18% below the 30-year average.
  • Karnataka argues that the impending end of the southwest monsoon limits the possibility of future reservoir inflows.
  • The CWRC and CWMA are scheduled to meet on September 8 to review the ground-level situation and the appeal.
