Watersheds in arid regions of the Southwestern U.S. are unique in several ways. Sustained periods of drought, periodic flash flooding and devastating wildfires are defining characteristics that result in a high degree of disturbance. Rapid population growth and increased recreational use are additional stressors to an increasingly finite resource. This project examines river and reservoir systems in Central Arizona specifically the Salt and Verde Rivers and their major reservoirs, Roosevelt, Apache, Canyon, Saguaro and Bartlett; the Central Arizona Project canal and it's storage reservoir, Lake Pleasant. These watersheds constitute an area larger than the states of Connecticut, Delaware, New Jersey and Rhode Island combined.
