Barriers
while construction of Tehri Dam
·
Building Tehri dam across a river, floods the land that would
otherwise be available for use, alters the landscape, affects the local
community that would have lived and worked on the flooded land, alters the
character of the river, and prevents the free movement of fish.
·
Due to construction of the dam
the river is needed to be diverted. Diverting a river affects the nature of the
countryside and does not lend itself to use on a large scale.
·
The surrounding ecosystems was
polluted and damaged while building Tehri dam because it is a large-scale hydro power plant.
·
A lot of environmentalist and local people have protested during the
construction of Tehri dam as it was the place where they have lived and worked
over the years.
