Apprehensive of the possibility of the British completely damming the flow of Ganga at Bhimgauda in Haridwar. Mahamana Pt. Madan Mohan Malaviyaji set up the Ganga Mahasabha in 1905. Due to Mahamana’s effort a massive public protest arose against the damming of Mother Ganga and the British Government had to buckle under the pressure. In 1916 an agreement was entered into with the British Government which provided;
1) In future, the incessant flow of Ganga will never be interfered with. (1916 Agreement, clause 32, Para-1)
2) No decision on Ganga will be taken without the consent of Hindu community. (1916 Agreement, clause 32, Para-1)
Under Mahamana’s leadership Indian Prince and lala Sukhbir Singh then General Secretary of Hindu Mahasabha signed this agreement which is binding even today under the article 363 of the Indian Constitution.
In 2005 the Ganga Mahasabha was restructured and has been playing the leading role in mass movements, public awareness campaigns and coordinating various other efforts to protect Mother Ganga.
