Notes

  • The Cauvery Water Management Authority (CWMA) is the apex body responsible for monitoring the implementation of the Supreme Court’s verdict regarding Cauvery water sharing.
  • CWMA has directed Karnataka and Tamil Nadu to maintain the status quo on water release and utilisation due to poor rainfall in the basin.
  • Both states are restricted to using reservoir storage exclusively for drinking water purposes, with a prohibition on irrigation usage.
  • The IMD has forecasted continued rainfall deficits, designating the current period as a 'distress year' for the Cauvery basin.
  • Data indicates Karnataka released 2.5 tmcft in June and 0.54 tmcft in July, which is below the prescribed levels.
  • The Cauvery Water Regulation Committee (CWRC) is tasked with assisting the CWMA and is scheduled to review the situation on July 28.
