Remove rocks from the open well

I have a domestic well (not bore well) very near to my house in the Malappuram district, Kerala. It is around 10 to 20 feet deep. Currently, water is not available, and the well is very new. We found rocks at the bottom while digging the well. My questions are:

1. If I dig further, will there be the possibility of striking water? To know this, will a scientific method will help?
