Bharti claimed that Bhagirathi river, on which Tehri dam is built, is trapped and a team is working on releasing a stream of the river which is a headstream of the Ganga.
Suggestions are also invited from people on the issue, she said during the inauguration of a hospital in Maneri.
She claimed that the Tehri dam project had received a green signal only after VHP leader Ashok Singhal was given an assurance that a stream of the river would be released from Dharasu to Devprayag.
She said Bhagirathi river has lost its natural form due to the construction of the dam and claimed that if a natural stream of Ganga is not released, it would be a betrayal for the Hindu society.
The minister said the central government is working on the Ganga cleanliness drive.
