The Tehri Reservoir fills-up the Bhagirathi valley, one of the headstreams of the Ganges (India)
The Tehri Dam was (and still is) a very controversial project, as it flooded two valleys resulting in the destruction of numerous villages and a town (Tehri), all now submerged, and forced the relocation of about 100,000 people.
