Its name stems from the Spanish word, piedra, meaning rock. The Piedra River is formed by the confluence of its East Fork and Middle Fork, deep in the San Juan Mountains. The Middle Fork, larger of the two, rises in a bowl-shaped valley in the San Juan National Forest. It flows southwards, and forms the Piedra after a journey of 12.5 miles.
The river originates in the Mogollon Mountains in western New Mexico and flows easterly through Arizona before flowing into the San Carlos Reservoir. In Arizona, the upper watershed drains 7,430 square miles and is within the Morenci, Duncan Valley, Bonita Creek, and Safford groundwater basin boundaries. Major tributaries of the Gila River within the area are the San Francisco River, Eagle Creek, Bonita Creek, San Simon Creek, and the San Carlos River. Agriculture is the major use of surface water in the watershed. Irrigation water is obtained from the Gila River at several diversion points and from wells pumping groundwater. Diversions from the river above Coolidge Dam have been regulated by the Gila Decree since 1936.
