I live in an area of NM that evreybody has a well, or hauls water in.

The drilling companies have “witchers”, and they hit a lot more often than they miss. A miraculous well in this neighborhood is 15 gallons a minute.

Salty or alkali?

Here's a comment from a well driller about dowsing:

I work for a small family-owned waterwell drilling company in west central IN. We deal with witchers almost daily. New customers want to know if it works, old timers are convinced. The geology in this part of Indiana is wildly varied. We have drilled sand and gravel wells anywhere from 40' to 240'. Several rock formations are found in our area. Rock wells can be anywhere from 50' to 400' with the yield between 10gal./hr. to 100+/ min. Let me assure you, no witcher has ever been any more than chance. As Randi has reported, any failure is written off. We have been told many times "You missed the water by 20' feet. Most well drillers will drill where a witcher picks. Most of the time it doesn't matter. The drillers knowledge is still the best bet.
