Where does your drinking water come from? Who owns the water? What is a water right? How is it valued? How do you assure a reliable water supply for your home, development project, business, farm, municipality or utility? Who gets water during a drought? Tonkon Torp's experienced water lawyers can help you answer all of these questions and more.
