Aravaipa Creek is a tributary of the San Pedro River that runs through Aravaipa Canyon, including the BLM Aravaipa Canyon Wilderness area, in Graham County and Pinal County of southeastern Arizona, It is home to seven native fish species, all of which are found naturally in this location. Although each of these species can be found in various other tributaries of the San Pedro and surrounding river systems, Arizona's native fish species are, in general, among the most imperiled in the United States and many efforts are being made to conserve them. This includes protecting their habitat from disturbance by humans and encroachment by non-native species that could potentially out-compete the native ones.
