Water witching (also called divining or water dowsing) is a practice used to locate ground water using a stick, rod, pendulum, or something similar. With the drought going on in the El Paso area, a lot of people are searching to have wells built for their farm or backyard. Robert Garcia is someone people go to before they begin the process of starting a water well, which can cost up to thousands of dollars. He said he uses the technique of water witching to identify the best location for finding water. Who can do it?
