Notes

  • The Cauvery water dispute involves the sharing of river water between the upper riparian state (Karnataka) and the lower riparian state (Tamil Nadu).
  • The legal framework for water sharing is governed by the 2007 final award of the Cauvery Water Disputes Tribunal (CWDT), as amended by the Supreme Court in 2018.
  • Implementation mechanisms include the Cauvery Water Management Authority (CWMA) and the Cauvery Water Regulation Committee.
  • Tamil Nadu has historically advocated for adjudication through established legal mechanisms rather than bilateral negotiations.
  • The dispute is exacerbated by deficient rainfall in the southwest monsoon, impacting water availability in the catchment areas.
  • A key point of contention is the proposed Mekedatu dam project, which the lower riparian state opposes due to potential impacts on irrigation requirements.
  • Previous attempts at bilateral negotiations between states have historically struggled to achieve breakthroughs in water-sharing agreements.
