Water is precious to Dwight Brinkerhoff. Over the decades he’s farmed in Wayne County, the goal has been to stretch water supplies. “It is the resource that we have that if we did not have, we would not be here,” he said. Farms in this southern Utah valley were irrigated by flooding when he was young, he said. Now, some of his neighbors have high-tech automated sprayers. The next evolution might be taking shape in one of his alfalfa fields.
