On the way to my grandpa?s house I crossed the river Kollidam; there is no water in the middle part.  It has only water at the bank side.  The other parts are look like a ground with sandy area and full of bushes.  In 90?s there is full of water.  I heard this from my mother.  But now due to climate change, global warming, lack of rain etc. there is a little bit of water only.  We must maintain the storage of water according to the population.  Then only we manage the water requirements in future.  Most of the dams are built by the Kings on those days in India. It is enough for those days population. We must increase our water storage capacity by maintain the old ones, built new dams, or cleaning the bushes etc from water resources. We must save water according to the now a day?s population.
