Himalayan Rivers Development
1. Construction of storage reservoirs on the principal tributaries of the Ganga and the Brahmaputra in India, Nepal and Bhutan, 2. Along with interlinking canal systems to transfer surplus flows of the eastern tributaries of the Ganga to the West. 3. Apart from linking of the main Brahmaputra and its tributaries with the Ganga and Ganga with Mahanadi.
The Himalayan component would provide additional irrigation of about 22 million hectare and generation of about 30 million KW of hydropower, besides providing substantial flood control in the Ganga & Brahmaputra basins. It would also provide the necessary discharge for augmentation of flows at Farakka required inter alia to flush the Calcutta port and the inland navigation facilities across the country.
