dam would generate about 7,500 MW but could submerge about 350 km 2 area, the
major part of which would to be in India and the rest in China.
The proposal also included a second dam across the Subansiri, another tributary
of the Brahmaputra on its right in Assam in hilly-cum-plain area. This would also
be a rock-fill dam, about 240 m high, and store up to 18,000 million M 3 (MCM)
to augment the dry season flow of the river by about 700 cumecs and also generate
about 1,800 MW but submerge about 100 km 2 area in Assam alone. These two
reservoirs would also help mitigate floods in the Brahmaputra basin and reduce the
peak flood of 1.50-1 million cusecs.
A third rock-fill dam was also proposed by India, to be constructed over the
Barak at a place, called Tipaimukh in Mizoram, which would directly augment the
flow of the Ganga. It will have a storage capacity of 7,000 million M 3 (MCM)
of water to augment the dry-season flow of the Ganga by about 300 cumecs and
generate about 600 MW of hydro-electric power. It would effectively control floods
in Cachar district in Assam as well as in Sylhet and Dhaka districts of Bangladesh.
