Water is not reusing again and again in hydel power station-Why?

Water is not reusing again and again in hydel power station-Why?

Many people are asking this question repeatedly while we have load shedding (power cut) or
while we are facing scarcity of water .Obviously the question is genuine.
In India especially in Kerala ,The electricity is generated from water as hydel power.
since it is very cheap in production and having good quality.
 One of the main  problem is that, during low rainfall period the electricity production gets decreased.This will leads to power cut hours in this areas.
As we know that the water gets flow from the storage or dam will rotates the turbine which leads to the production of electricity.After that water gets move out freely.
So that is why the people are raising this type of question.

                               After the generation of electricity we get a value that is our required current,
the water wants to Pumbs back in order to reuse the water If we are pumbing the water (that gets moved out) back to the dam itself large amount of energy gets lost from our generated electricity.This is because the water wants to send back to the a large height which should take much energy.If we want to check again this, water again used for rotating turbine after we pumbed the water to the storage.Thus next value of electricity energy will produce.
But the present energy will not reach to our target electricity,so we can conclude that its better not to  reuse the water for production .
That`s why water is not reusing again and again in hydel power station .
