NBA may be attached to the tribals and others whose livelyhood depends on the river. But the increase in height is going to help of lot more people's water problem than the people who are affected by it. Rather than protesting against the increase in heights, protest if the government is not doing enough to help the displaced people. It is really hard to leave a place where you all may have lived for 100 or more yrs. But India's development is the main priority.
