I was a skeptic on water witching/divining but now believe in it.
About 20 years ago we decided to have a well dug on our place. So, I called a local driller who came out and asked where I wanted it. The most convenient place was close to the house and he poked a hole in the ground there. Nada, no water found. So, we tried a couple of other random spots, went down to 500 ft again with no results. I paid him and he left. There went $10,000 and I got into the beer.
A couple of days later, I thought of witching/divining. I bent a couple of brass rods and stated walking around the field in front of the house. At one point one of them swung. I walked over the same place a couple of times with no result but marked the spot. It didn't happen again anywhere in the 3 or 4 acres. So, I started asking around about water witching and got referred to a guy. He came out and used a couple of forked willow limbs. At the point where the brass rod had indicated, the sticks pulled down. He said it was either a lot of water or water close to the surface. When I held the sticks nothing happened. Then, a local cowboy buddy of mine dropped by and tried it. In his hands the sticks pulled down so hard that he had trouble holding them. The bark on the wood actually started cracking. I tried it again with no results. When he tried it again, I put my hands on the sticks and all activity stopped. I just can't do it.
I had a well dug there and found water. It was at 70 ft. and most wells in the area were at 400+ ft. But, it was only 1/10 gpm and most wells in the area produce 5 to 10 or more gpm. Not much. However, I went to the local plumbing/well supply place, asked questions, and bought a 2,500 gallon holding tank. It comes out of the well, into the tank and then into a well house where I have the pump and pressure tank that then goes to the house and corrals. That 1/10 gpm is 24/365 so I have no problems. Well, no problems as long as I winterize it every time I leave during the winter. Cast iron pumps can dang sure freeze and break.
