July 31 , 2026 13 hrs 0 min 34 0
  • The Neyyar water-sharing issue is in focus as the long-pending legal dispute between Tamil Nadu and Kerala over Neyyar River water continues before the Supreme Court.
  • The Neyyar Irrigation Project began in 1951, and Tamil Nadu started receiving irrigation water through the Neyyar Left Bank Canal from 1958 without a formal written agreement.
  • The project was designed to irrigate 36,000 acres, including about 9,000 acres in Kanniyakumari district, Tamil Nadu.
  • Kerala supplied around 150 cusecs of water to Tamil Nadu for nearly 40 years, based on mutual understanding.
  • In 2004, Kerala stopped releasing Neyyar water, leading to a dispute over water sharing and whether the Neyyar is an inter-State River.
  • Tamil Nadu approached the Supreme Court in 2012, and the case is pending, with arguments yet to begin.
