The Conchos River "(Río Conchos)" is a large river in the Mexican state of Chihuahua. It meets the Río Bravo del Norte / Rio Grande at the town of Ojinaga, Chihuahua.


The Conchos is the main river in the state of Chihuahua and the Rio Grande's main Mexican tributary. It has several reservoirs that make use of its water for agricultural and hydropower uses.

The Conchos rises in the Sierra Madre Occidental near Bocoyna, Chihuahua, where it heads east and receives several tributaries along the way. At Zaragoza, Chihuahua, it is stopped at the Presa de la Boquilla dam, the largest in Chihuahua forming Toronto Lake. It then heads east again forming Colina Lake and then passes through Camargo, Chihuahua, the main agricultural center in the region, where it receives the Florido as a tributary.

From there the Conchos heads north, receiving the San Pedro near Delicias, Chihuahua, entering the Chihuahua Desert and cutting a path through it, before turning to the northeast. At Aldama, Chihuahua, it is dammed by the Presa El Granero, then cuts through a canyon called the Peguis Canyon, before forming a last dam (Toribio Ortega) near Ojinaga. At Ojinaga it joins the Rio Bravo (Grande).
