Utah's Future Water Problems, Wayne D. Criddle

Faculty Honor Lectures

Utah is rapidly changing from what was once predominately an agricultural state to an urban and industrial state. This shift is not decreasing our water needs; it is often intensifying these needs and creating many new problems. Perhaps we should ask ourselves-are we prepared to recognize and accept these changes?
