(a) to (d) The average annual precipitation is estimated as 4000 Billion Cubic Metre (BCM) in the country. After accounting for the natural process of evaporation and transpiration through vegetation etc., the average annual water availability in the country is assessed as 1869 BCM. Owing to topographic, hydrological and other constraints, the utilizable water is assessed as 1122 BCM. 629 BCM of water is being utilized for diverse purposes. Rest of the water could be considered to be flowing down to sea.

State Governments conceive, plan and implement major, medium & minor schemes for utilisation of water resources. Storage capacity of about 213 Billion Cubic Metre (BCM) has been created so far. As per present assessment, the total estimated storage capacity of the various projects under construction is about 76 BCM and that for the projects under formulation is about 108 BCM.

It has been estimated that irrigation potential of 3.34 million hectares has been created during 2003-04 and 2004- 05.
