Hello.
If you dig a pond, take someone with experience.
When I dug my first pond, it appeared a beautiful vein of water in the rock with lots of pressure, but the operator continued to work around the veine, we lost it completely.
After talking with a well driller, he told me that the operator should not have insisted and should have left the veine quiet, by working around he move some rocks (the machinery it's strong), and the water change the direction.
A+
