Notes
1. Inland Water resources of the country are classified as rivers and canals; reservoirs; tanks & ponds; beels, oxbow lakes, derelict water; and brackish water.
2. Water bodies other than rivers and canals cover an area of 8.6 million hectares. Reservoirs have maximum area (2.8 million hectares.) followed by Tanks and ponds (2.4 million hectares.). The total length of rivers and canals in India is reported to be 280,751 km.
3. The above data pertains to the position in the year 2021 as per the source document. It has been furnished under Statement-1.07 in the above-mentioned source. The figures for 'Total-NE Region' have been computed on the basis of the state-wise data given in the above table.

1. Ground water is 'water within the earth that supplies wells and springs; water in the zone of saturation where all openings in rocks and soil are filled, the upper surface of which forms the water table'.
2. The above figures (including those in the source document) have been rounded off to two decimal places. Hence, some of the totals or percentages may not appear to tally. The figures for NE Region, including the 'Stage of Ground Water Extraction' for the region as a whole, have been computed on the basis of the state-wise data given in the above table
3. The above table gives the status of ground water resources for the year 2022.
4. The Current Annual Ground Water Extraction refers to the utilization of the ground water resources for various purposes like irrigation, industry, and domestic uses. The stage of ground water extraction reflects the total annual use of ground resources as a percentage of the Annual Extractable Ground Water Resource.
