About Mahadayi (Mandovi) river
- It is the Lifeline of the Indian state of Goa
- The Mandovi and the Zuari are the two primary rivers in the state of Goa.
- Mandovi joins with the Zuari at a common creek at Cabo Aguada, forming the Mormugao harbour
- It rises in the Western Ghats, from the Bhimgad Wildlife Sanctuary in Belagavi district of Karnataka.
- Flowing westward, it enters Goa. Over two-thirds of the river’s stretch lies in Goa (76km).
- River Mahadayi joins the Arabian Sea at Panaji, Goa.
What is the Kalasa-Banduri Nala project?
- The Kalasa Banduri Nala project aims to divert water from Mahadayi to satisfy the drinking water needs of Belagavi, Dharwad, Bagalkot and Gadag districts.
- 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.
Why is the Dispute?
- In 2002, two-and-a-half decades since the proposal, the Karnataka government decided to implement the project, after the Centre cleared it.
- Goa, under its then CM , approached the Centre, urging it to assess the available resources in the river and allocate water to the three basin states — Goa, Maharashtra and Karnataka.
- Due to the protests in Goa and also due to concerns over ecological damage, the project was put on hold by the then NDA government.
- The dispute gained steam in 2006, when the JD(S)-BJP coalition government in Karnataka decided to start work on the project.
- Goa then approached the Supreme Court, seeking the creation of a Tribunal to settle the water sharing dispute.
- A Tribunal was finally set up by the UPA government in November 2010.
What did the Tribunal say?
- The Tribunal in 2018 awarded 13.42 TMC water from Mahadayi river basin to Karnataka, 1.33 TMC to Maharashtra and 24 TMC to Goa.
- In Karnataka’s share, 5.5 TMC was to meet drinking water needs and 8.02 TMC was for hydro-electricity generation.
- Of the 5.5 TMC, 3.8 TMC was to be diverted to Malaprabha basin through Kalasa and Banduri Nalas (canals).
- This was notified by the Central government in February 2020.
What happened after the notification?
- After the Tribunal award, Goa filed a Special Leave Petition in the Supreme Court in July 2019, challenging the quantum of allocation.
- Subsequently, in October 2020, it filed a contempt petition before the SC, accusing Karnataka of illegally diverting water from the Mahadayi basin.
- Civil appeals were also filed by Maharashtra over the dispute.
- The project has been a long-standing demand of Karnataka residents set to benefit from it.
