With its red rock and steep cliffs and canyons, the terrain of Washington County, Utah, is breathtaking and is one of the most geologically diverse areas in the world. This location, however, also lends itself to drought. It is the driest county in the state, receiving only an estimated eight inches of rainfall a year in its major population centers. Compare this to other U.S. counties that receive an average of 39 inches of rainfall annually. Couple that with the fact that Washington County is the fastest growing county in Utah, with population growth expected to be 229% over the next 50 years, and you have the makings for a severe water shortage in the future.
