Notes

  • The Cauvery Water Management Authority (CWMA) has directed Karnataka to release 9,000 cusecs of water daily to Tamil Nadu for 15 days.
  • The total quantum of water to be released amounts to 11.66 tmc ft.
  • Karnataka requested a reduction to 6,000 cusecs, citing severe hydrological distress and a 49.18% deficit in cumulative inflows into its four Cauvery basin reservoirs compared to the 30-year average.
  • Karnataka reported an excess release of 2.807 tmc ft between July 29 and August 23, citing 18.748 tmc ft delivered against an ordered 15.940 tmc ft.
  • Tamil Nadu claimed a backlog of 17.49 tmc ft and requested a total release of 28.386 tmc ft for the period of August 24 to September 7.
  • The CWMA serves as the regulatory body overseeing the implementation of water-sharing arrangements between basin states.
