Dada, Here is an obsolete list of
MAJOR Dams and Barrages in just West Bengal, there are others like Gajoldoba Barrage and I haven't even mentioned the ones in Assam, Meghalaya and other NE states. I wouldn't call these "nothing significant" or "Few minor level constructions".
India is unilaterally and blatantly withdrawing water without regard to international upstream riparian conventions and laws.
- Durgapur Barrage on River Damodar
- Farakka Barrage on River Ganges
- Tilpara Barrage on River Mayurakshi
- Jaldhaka Barrage on Jaldhaka river
- Teesta Barrage on Teesta river
- Maithon and Panchet Dam on River Damodar
The more of these illegal barrages you have - the more the chances of flooding upstream of these installations.
But I guess the Chinese even further upstream will take care of these barrages and dams.
