The Yaqui River (Río Yaqui in Spanish) (Hiak Vatwe in the Yaqui or Yoeme language) is a river in the state of Sonora in northwestern Mexico. Being the largest river system in the state of Sonora, the Yaqui river is used for irrigation.
Approximately 320 km (200 mi) in length, the Rio Yaqui flows south and southwest to empty into the Gulf of California.
Its course is interrupted by several reservoirs like Plutarco Elías Calles (El Novillo), Lázaro Cárdenas (Angostura), or Álvaro Obregón (El Oviáchic, Lake Ouiachic), which provides the water resource for the intensively irrigated region of Ciudad Obregón.
As early as 552 AD, native inhabitants known as the Yoem Vatwe or Yaqui were living in family groups along the Rio Yaqui. The Yaqui used simple irrigation techniques to cultivate corn, beans, and squash while also hunting local game and gathering wild foods from the area. Yaquis traded native foods, furs, shells, salt, and other goods with many indigenous groups of central North America. The Yaquis lived more or less independently until the late 1800s, when many of them were driven from their lands surrounding the Rio Yaqui by the Mexican Army and forced to flee to more remote areas. Many Yaquis left the Rio Yaqui area to fight in the Vakatetteve Mountains, while others relocated to Yaqui communities in Arizona. By the late 1880s, warfare with the Mexican Army had killed off many members of the Yaqui tribe, so that only 4,000 Yaquis remained in the Rio Yaqui area.
In the early 1900s, after a series of conflicts with the Mexican Army, most of the remaining Yaqui were arrested and dispersed to plantations in the Yucatán Peninsula. The survivors continued resisting until the late 1920s, when Mexican authorities overcame resistance by employing heavy artillery and aircraft to bomb and shell Yaqui villages.
Also in the early 1900s, Major Frederick Russell Burnham, the celebrated American scout, went to Mexico in search of minerals resources. While there he met the naturalist Dr. Charles Frederick Holder and the two men soon became associated with the early Yaqui River irrigation project. Burnham reasoned that a dam could provide year-round water to rich alluvial soil in the valley; turning the region into one of the garden spots of the world and generate much needed electricity. He purchased water rights and some 300 acres (1.2 km2) of land in this region and contacted an old friend from Africa, John Hays Hammond, who conducted his own studies and then purchased an additional 900,000 acres (3,600 km2) of this land—an area the size of Rhode Island. He became a close business associate of Hammond and led a team of 500 men in guarding mining properties owned by Hammond, J.P. Morgan, and the Guggenheims in the Mexican state of Sonora. Just as the irrigation and mining projects were nearing completion in 1912, a long series of Mexican revolutions began. The final blow to these efforts came in 1917 when Mexico passed laws prohibiting the sale of land to foreigners. Burnham and Hammond carried their properties until 1930 and then sold them to the Mexican government.
Burnham together with Holder made important archeological discoveries of Mayan civilization in this region, including the Esperanza Stone. In his book, The Book of the Damned, Charles Forte would use this stone as proof that aliens from outer space had been on Earth. The supernatural nature of this stone would be perpetuated by many other authors in several subsequent books on anomalistics.
The Rio Yaqui was once home to the American crocodile (Crocodylus acutus) and represented one of the northernmost natural locations for the species. Decades of environmental degradation in the region led to the extirpation of the species from the region.
