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 the 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.
