1. Meaning of Ground Water

• Water located beneath the ground surface.

 Groundwater is stored in and moves slowly through layers of soil, sand and rocks called aquifers. Aquifers typically consist of gravel, sand, sandstone, or fractured rock, like limestone.

Introduction:

Of these, as many as 36 reservoirs are having significant hydro-power benefits with installed capacities of more than 60MW each. The combined live storage in these 81 reservoirs at the beginning of monsoon, i.e. June 1, 2010 was 14% of their designed capacity and stood at 60% of designed capacity as on January 27, 2011. The present storage is 137% of last year’s storage and 145% of last 10 years average storage during the same period. Out of these 81 reservoirs there are presently 15 reservoirs where this year’s storage is less than 80 % of the average of previous 10 years and in remaining 66 reservoirs the storage is more than 80% of the average of previous 10 years.
