I believe it is 160'. When I purchased property had an old windmill there but hole was dry. Driller came in and cleaned up, found a little water, but could pump it dry in an hour or so. He suggested "blasting the hole". He loaded a charge, placed it at 140' and it shook for 1/2 a mile! He said prior to blasting this would be a 1 time fix or nothing at all. It has flowed ever since. I had never heard of this but it worked for me. With the drought surprised it is still flowing.
