The average annual precipitation received in India is 4,000 km3, out of which 700 km3 is immediately lost to the atmosphere, 2,150 km3 soaks into the ground and 1,150 km3 flows as surface runoff. The total water resources in the country have been estimated as 1,953 km3. Nearly 62% or 1,202 km3 of the total water resources is available in the Ganga-Brahmaputra-Meghna basin. The remaining 23 basins have 751 km3 of the total water resources.
