On a recent sunny Monday morning, 85-year-old Doug Brown pulled up to a breakfast joint in Willits in his white pickup. Bold white letters on the tinted camper shell window spelled out “Water Witcher,” with Brown’s phone number written just below. Inside the truck was a quiver of wire rods, each tipped with different metals or materials, to be used for Brown’s practice of an archaic tradition: water dowsing. In an age defined by dry spells and dwindling resources, an unlikely group continues to quietly deploy their centuries-old practice in search of water. Called dowsers, water witchers or diviners, members of this eclectic guild claim they can locate the Earth’s hidden reservoirs using primitive technology and intuition, all for a price.
