White River (Arizona) White River (Arizona) The White River is a tributary of the Salt River in the U.S. state of Arizona. Formed by two forks that drain part of the White Mountains, it begins in Navajo County and ends in Gila County, where it meets the Black River to form the Salt River. The White River lies entirely within the Fort Apache Indian Reservation in the east-central part of the state. The North Fork White River and the East Fork White River merge near Fort Apache to form the main stem, which continues generally southwest to its confluence with the Black River.
