An excerpt:

India has 4,500 large dams.
Until recently, the pristine stretch between Uttarkashi and Gangotri boasted
of only one: Maneri Bhali Phase I. But a series of consecutive hydro-electric
projects are now in different stages of construction on this 125-kilometre
stretch. Five major ones threaten the normal existence of the Bhagirathi,
as the majestic Ganga here is called. If they go through as planned, it
is feared the Ganga may completely disappear from large stretches, leaving
the riverbed limp and dry.
