The 'Gila' 'River' (
O'odham [Pima]: 'Hila Akimel') is a
tributary of the
Colorado River, 649
mile (1,044
km) long, in the southwestern
United States.
It rises in western
New Mexico, in
Sierra County on the western slope of
continental divide in the
Black Range. It flows southwest to the
Gila National Forest and
Gila Cliff Dwellings National Monument, then westward into
Arizona, past the city of
Safford, and along the southern slope of the
Gila Mountains. It emerges from the mountains into the valley southeast of
Phoenix, where it crosses the
Gila River Indian Reservation as an intermittent
stream, due to its use as a water source. West of Phoenix, it turns abruptly southward along the
Gila Bend Mountains, then abruptly westward again near the town of
Gila Bend, Arizona. It flows southwestward and joins the Colorado near
Yuma, Arizona.
The Gila is one of the largest desert rivers in the world. It and its chief tributary, the
Salt River, would both be perennial streams carrying large volumes of water, but irrigation and municipal water diversions turn both into largely dry rivers. Below Phoenix to the Colorado River, the Gila is largely a trickle or dry, as is the lower Salt from Granite Reef Diversion Dam downstream to the Gila. The natural mean flow of the Gila is 6130 ft³/s (174 m³/s) at its mouth with the Colorado. The Gila used to be navigable by small craft from its mouth to near the Arizona - New Mexico border. The width varied from 150 - 1200 feet with a depth from 2 - 40 feet.
After the
Treaty of Guadalupe-Hidalgo in
1848, the river served as the border between the United States and
Mexico until the
1853 Gadsden Purchase extended U.S. territory south of the Gila.
The Gila River is dammed by the
Coolidge Dam 31 miles east of
Globe, AZ.
Hila Akimel O'odham

Middle Fork of the Gila River
A band of Pima (autonym "Akimel O'odham", river people), the Hila Akimel O'odham (Gila River People), have lived on the banks of the Gila River since before the arrival of Spanish explorers.
Their traditional way of life (''himdagĭ'', sometimes rendered in English as Him-dak) was and is centered at the river, which is considered holy. Traditionally, sand from the banks of the river is used as an exfoliant when bathing (often in rainstorms, especially during the monsoon).
In the
GRIC, the traditional way of life has generally been better preserved than in the
SRPMIC. Some speculate this may be due to the fact that the Gila River, a central aspect of the traditional way of life, still flows through the reservation year-round (although at times as an intermittent stream), while the Salt River does not.
