The Himalayas are the source of three major Indian rivers namely the Indus, the Ganga and the Brahmaputra. Ganga drains a basin of extraordinary variation in altitude,climate, land use, flora & fauna, social and cultural life. Ganga has been a cradle of human civilization since time immemorial. Millions depend on this great river for physical and spiritual sustenance. People have immense faith in the powers of healing and regeneration of the Ganga. It is arguably the most sacred river in the world and is deeply revered by the people of India.
The River plays a vital role in religious ceremonies and rituals. To bathe in Ganga is a lifelong ambition of many who congregate in large numbers for several river centered festivals such as Kumbh Mela and numerous Snan (bath) festivals.
Ganga basin is the largest river basin in India in terms of catchment area, constituting 26% of the country's land mass (8,61,404 Sq. km) and supporting about 43% of its population (448.3 million as per 2001 census).
The basin covers 11 states viz., Uttarakhand, U.P., M.P., Rajasthan, Haryana, Himachal Pradesh, Chhattisgarh, Jharkhand, Bihar, West Bengal and Delhi.The current focus of world bank funded National Ganga River Basin Projects (NGRBP) of NMCG is on five major states on the main stem of river Ganga namely Uttarakhand, Uttar Pradesh, Jharkhand, Bihar and West Bengal.

National Mission for Clean Ganga (NMCG) is the implementation wing of National Ganga River Basin Authority (NGRBA). At national level NMCG is the coordinating body and is being supported by States Level Program Management Groups (SPMGs) of UP, Uttarakhand, Bihar and West Bengal which, are also registered as societies under Societies Registration Act, 1860 and a dedicated Nodal Cell in Jharkhand.
The area of operation of NMCG shall be the Ganga River Basin, including the states through which Ganga flows, as well as the National Capital Territory of Delhi. The area of operation may be extended, varied or altered in future, by the Governing Council to such other states through which major tributaries of the river Ganga flow, and as the National Ganga River Basin Authority (NGRBA) may decide for the purpose of effective abatement of pollution and conservation of the river Ganga.
Vision
The Vision for Ganga Rejuvenation constitutes restoring the wholesomeness of the river defined in terms of ensuring “Aviral Dhara” (Continuous Flow”), “Nirmal Dhara”(“Unpolluted Flow”), Geologic and ecological integrity.
Key Functions
To achieve the objectives, NMCG shall carry out the following key functions namely:
The Plan is being prepared with the objectives of taking comprehensive measures for restoration of the wholesomeness of the Ganga ecosystem and improvement of its ecological health, with due regard to the issue of competing water uses in the river basin.
The wholesomeness of the river can be grasped in terms of four defining concepts:
Aviral Dhara (Continuous Flow)
Nirmal Dhara (Unpolluted Flow)
Geologic Entity
Ecological Entity
