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.
