Water is the most important resource of a country and of the entire society as a whole since no life is possible without water. Water may occur in nature in liquid, solid as well as in gaseous form. All these forms of water are very useful to mankind. About 97% of the total available water on earth is contained in oceans, and is, hence, saline or salty in nature. The amount of fresh (sweet) water actually available is only about 3 % of the total quantity of water on the earth. Looking to the above, the reality is that there is essentially very less fresh water on the planet today and with development and population increase need for water increases day by day, so planning should be done for restoring the available water for the need of future generation. The proper conservation, maintenance, and careful use of water resources, along with developing additional storages, may considerably reduce the chances of water famines for future generations to come. In addition to these measures, we may have to find out means and ways for increasing the available usable water by developing artificial rain technology, easier ways to desalt sea water at cheaper rates, recharging the unconfined aquifers by constructing small check dams on small rivulets. Here, an attempt is made to study the ground water fluctuations in the Yerala river basin, located in Sangli and Satara district situated in Maharashtra state, India. Ground water table in the Yerala river basin decrease from 8 to 1.5 m Below Ground Level (BGL) during period of 2001 to 2010.
