QUESTION
Question on receding water level in borewell

Hi,

We drilled a borewell of 780 ft in a village near to Salem, TN on May 2015. We chose the spot using the inputs of both a hydrogeologist and a water diviner.During drilling the water started oozing out at 180 feet and we went for more since the water diviner suggested that there is a possibility of more water. We didn't install the pump for 4-5 months since it was not necessary for us to do so immediately. But when we checked, the water is available only from around 550 feet.

Is there any explainable reason on why the water table went so low, since we drilled during summer and tried to install the pump after monsoon even though the rainfall was not heavy?

Thanks,

Vivek
