Kalasa-Banduri Nala Project:
On December 30, 2022, Karnataka Chief Minister Basavaraj Bommai told the Legislative Assembly that the government had received clearance from the Centre for two Detailed Project Reports (DPRs) on the Kalasa-Banduri Nala on the Mahadayi.
- It has escalated its long-standing dispute on the issue with neighbouring Goa.
- 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.
- Mahadayi originates inside the Bhimgad Wildlife Sanctuary in the Belagavi district of Karnataka and flows into the Arabian Sea in Goa.
- A Tribunal was set up by the UPA government in November 2010.
- 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.
