tehri dam - tehri hydro power project (india)


Downstream view of the Tehri Dam and of parts of its hydro power house (India)

On the left, the overflow spillway channel can be seen.­

The Tehri Dam was (and still is) a very controversial project, as it flooded a valley resulting in the destruction of numerous villages and a town (Tehri), and forced the relocation of about 100,000 people in the Bhagirathi Valley, one of the headstreams of the Ganges river.­

The Tehri Dam is the tallest dam in India and one of the tallest in the world.­ The dam is a 260.­5 metres (855 ft) high rock and earth-fill embankment dam.­ The dam creates a reservoir with a surface area of 52 square kilometres (20 sq mi).­

The Tehri Dam created a huge artificial lake in the Bhilangna valley and Bhagirathi valley, two headstreams of the Ganges.­

The Tehri Dam was (and still is) a very controversial project, as the flooding of the upstream valleys resulted in the destruction of numerous villages and a town (Tehri) that are now submerged, and forced the relocation of about 100,000 people.­

The Tehri Dam is the tallest dam in India and one of the tallest in the world.­ The dam is a 260.­5 metres (855 ft) high rock and earth-fill embankment dam.­ Its length is 575 metres (1,886 ft), crest width 20 metres (66 ft), and base width 1,128 metres (3,701 ft).­ The dam creates a reservoir of 4.­0 cubic kilometres (3,200,000 acre¬∑ft) with a surface area of 52 square kilometres (20 sq mi).­

It generates 1,000 megawatts of hydroelectricity.­

Since 2005, filling of the reservoir has led to the reduced flow of Bhagirathi water from the normal 1,000 cubic feet per second (28 m3/­s) to a mere 200 cubic feet per second (5.­7 m3/­s).­ This reduction has been central to local protest against the dam, since the Bhagirathi is considered part of the sacred Ganges whose waters are crucial to Hindu beliefs.­
