One of the development projects planned in the past on the Manas River envisaged flood control in the Brahmaputra River and augmentation of flows in the Ganga river system by building a dam on the river at the Indo-Bhutan border. The stored water stored behind the reservoir was proposed to be transferred through a long canal system through the foot hills of the Himalayas (skirting Bangladesh) crossing 25 major and minor rivers, out of which the major rivers the Sankosh, Raidak, Amo (Torsa), Kartoya, Teesta, Atrai and Mahananda through North Bengal, and finally out falling into the Kosi River in North Bihar. The project has not proceeded further due to several adverse public opinion and environmental concerns.
