Despite fears that the flow of the Bhagirathi, the main tributary of the Ganga, is falling in volume, the government has said there is no such threat to the river and the "natural' receding of the Gangotri glacier does not require any corrective measures.

Therefore, the question of Ganga going far away from the main source does not arise,' earth sciences minister Kapil Sibal informed the Parliament.
