The Salt Watershed (HUC 05140102) covers about 1,620 square miles in central Arizona. It includes parts of Maricopa and Pinal counties, and the Salt River and its tributaries run through it. The watershed receives most of its precipitation during the winter months, and snowpack in the higher elevations plays a crucial role in the hydrology of the region. The Salt River Project manages several reservoirs in the watershed, including Theodore Roosevelt Lake and Saguaro Lake, which provide water for irrigation, power generation, and recreation. The reservoirs also serve as key habitats for fish species, including the federally endangered Apache trout. The climate in the Salt Watershed is characterized by hot summers and mild winters, with occasional monsoonal storms during the summer months. However, recent trends show a decrease in snowpack and increased frequency of drought conditions, highlighting the need for sustainable water management practices in the region.
