Why in the news? 

The National Board for Wildlife (NBWL) recently deferred the decision on diverting forest land from the Kali and Sahyadri tiger reserves for the construction of a part of the Karnataka government's 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 Kalasa-Banduri project aims to divert water from Mahadayi to satisfy the drinking water needs of Belagavi, Dharwad, Bagalkot and Gadag districts 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: It rises in the Western Ghats from the Bhimgad Wildlife Sanctuary in Khanapur taluk of Karnataka’s Belagavi district.
• The river travels35 km in Karnataka, and 82 km in Goa before joining the Arabian Sea at Panaji (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, Bhanduri Nala, Surla Nala, Haltar Nala, Poti Nala, Mahadayi Nala, Pansheer Nala, Bail Nala and Andher Nala.
