Uttaranchal
Highlight - Tehri Dam
The Tehri Dam on India’s
Bhagirathi River, the main tributary of the Ganges, is one of
the world's largest and most controversial hydroelectric projects.
Under construction since 1978, the final phase of reservoir
filling is scheduled to start by December 2002. Within six months
the homes and lands of around 100,000 people would be submerged.
Power production is planned to begin in August 2003.
Tehri is located 200 miles north east of Delhi, in the state
of Uttaranchal. With a height of 260 meters (855 feet), the
dam will be the fifth tallest in the world. Its reservoir
will completely submerge Tehri Town and 40 villages, and partially
submerge 72 villages.
The two lower tunnels of the dam were closed in December
2001 submerging the main bridge leading to Tehri town and
nearby areas. The last two tunnels, which are at a higher
level, are scheduled to be closed by December 2002. This will
result in complete submergence of Tehri Town and surrounding
villages.
