Proprietor Marc Mondavi demonstrates dowsing with "diving rods" to locate water at the Charles Krug winery in St. Helena, Calif.
In the middle of a record drought, some California farmers have hired dowsers — also known as “water witches” — to use uncommon techniques to find underground water, The Associated Press reports.
Dowsers extend copper or wooden sticks called “divining rods” over the ground to find new wells. Bronco Wine Co., the fourth largest winemaker in the U.S. (and the maker of Two Buck Chuck), employs dowsers on its 40,000-acre property, according to the AP.
The AP reports Napa Valley’s best-known “water witch” is winemaker Marc Mondavi, who charges as much as $500 per visit.
The state’s Department of Water Resources and the U.S. Geological Survey do not endorse the practice, arguing that there is no scientific basis to it.
