Arizona is a state with arid to semi-arid climate conditions. Major surface flows include the Colorado and Gila Rivers, with the former having significant impacts on water supply and hydroelectricity generation. Reservoirs and dams, such as Lake Powell and Hoover Dam, play critical roles in water storage and management. The state's hydrology is primarily influenced by snowmelt from the Rocky Mountains and the monsoon season, which brings heavy rainfall to the region during the summer months. Watershed data indicates that the Salt and Verde Rivers are the primary sources of water for the Phoenix metropolitan area. Climate change is expected to exacerbate water scarcity issues in the region, with reduced snowpack and increased temperatures leading to higher evaporation rates and reduced water availability.
