==Annual flows and other data==
India experiences an average precipitation of 1,170&nbsp;mm per year, or about 4,000&nbsp;km<sup>3</sup> of rains annually.<ref name=fao1/> Some 80% of its area experiences rains of 750&nbsp;mm or more a year. However, this rain is not uniform in time or geography. Most of the rains occur during its monsoon seasons (June to September), with the northeast and north receiving far more rains than India's west and south. Other than rains, the melting of snow year round over the Himalayas feeds the northern rivers to varying degrees. The southern rivers, however experience more flow variability over the year. For the Himalayan basin, this leads to flooding in some months and water scarcity in others. Despite extensive river system, safe clean drinking water as well as irrigation water supplies for sustainable agriculture are in shortage across India, in part because it has, as yet, harnessed a small fraction of its available and recoverable surface water resource.<ref>K.L. Rao, India's Water Wealth, ISBN 978-8125007043, 1979</ref> India harnessed 761&nbsp;km<sup>3</sup> (20%) of its water resources in 2010, part of which came from unsustainable use of groundwater. Of the water it withdrew from its rivers and groundwater wells, India dedicated about 688&nbsp;km<sup>3</sup> to irrigation, 56&nbsp;km<sup>3</sup> to municipal and drinking water applications and 17&nbsp;km<sup>3</sup> to industry.<ref name=fao1/>

According to 2011 report of the Food and Agriculture Organization of the United Nations, India's basin wise distribution of catchment area and utilizable surface water resources is presented in the following table:<ref name=fao1>FAO, [http://www.fao.org/nr/water/aquastat/countries_regions/IND/IND-CP_eng.pdf India - Rivers Catchment], Aquastat, United Nations (2011)</ref>
