The Karnataka government recently submitted a revised proposal to the National Wildlife Board (NWD) and Ministry of Environment, Forest and Climate Change (MoEFC) for the Kalasa-Banduri project.


About Kalasa-Banduri Project:


  • The project involves the construction of dams and a canal system to divert water from the Mahadayi River, located in Goa, to the Malaprabha River (a tributary of Krishna river) basin in Karnataka.
  • The main goal of the project is to meet the drinking water needs of the districts of Belagavi, Dharwad, Bagalkot, and Gadag in Karnataka.
  • Though the project was first proposed in the early 1980s, it has remained on paper owing to a dispute between Karnataka, Goa and Maharashtra.
  • As per plans, barrages are to be built against Kalasa and Banduri streams — tributaries of Mahadayi — and water diverted towards Karnataka’s parched districts.

Key facts about Mahadayi river:

  • Origin: Mahadayi river rises in the Western Ghats, from the Bhimgad Wildlife Sanctuary in Khanapur taluk of Karnataka’s Belagavi district.
  • The river travels 35 km in Karnataka; 82 km in Goa before joining the Arabian Sea at Panji (North-Goa).
  • Also called Mandovi in Goa, Mahadayi is a rain-fed river that is shared between Karnataka and Goa for their water needs.
  • The Salim Ali Bird Sanctuary is located on the island of Chorao in the Mandovi river.
  • Major Tributaries: Kalasa Nala, Banduri Nala, Surla Nala, Haltar Nala, Poti Nala, Mahadayi Nala, Pansheer Nala, Bail Nala, Andher Nala.
