Yes, water witching has been in existence for a long time. Only some people have this ability. My great grandmother would take a fresh twitch off of a weeping willow, shaped like a "Y". She would invert her hands, grasping the twig handles with wrists pointed in, she could walk across the water line and we would see the top of the branch literally bend toward the ground.
Proven time and time again, she located the drilling spots for the wells in the farm neighborhood that she lived in.
Some of us grandkids have the talent too, although not tested for decades. It's a gift.
Some call it dousing some witching. I like to call it dousing better. I can use to steel/brass rods with a ninty degree bent at one end to hold on to , or I can use a willow branch shaped like a sling shot with the ends you hold no bigger then 3 sixteeth of an inch in diameter. I can tell you which way the water is flowing. If its a strong or week flow but I can't tell how deep it is.
