The Río Conchos (Conchos River) is a large river in the Mexican state of Chihuahua. It joins the Río Bravo del Norte (known in the United States as the Rio Grande) at the town of Ojinaga, Chihuahua.
The Rio Conchos is the main river in the state of Chihuahua and the Rio Grande's largest tributary. It is one of the most important river systems in all of northern Mexico. The Conchos has several reservoirs that make use of its water for agricultural and hydropower uses.
The Conchos rises in the Sierra Madre Occidental near Bocoyna in the municipality of Guadalupe, Chihuahua, where it heads east and receives several tributaries along the way. At Valle de Zaragoza municipality, 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 the Peguis Canyon, before forming a last dam (Toribio Ortega) near Ojinaga. At Ojinaga, it joins the Rio Bravo (Rio Grande in the U.S.).
Rio Conchos is a 1964 Cinemascope Western starring Richard Boone, Stuart Whitman, Tony Franciosa, Edmond O'Brien, and in his motion picture debut, Jim Brown, based on Clair Huffaker's novel of the same name.
Huffaker's novel is reminiscent of the John Wayne-starring films The Comancheros (for which Huffaker co-wrote the screenplay) and The Searchers. The main female role, played by Wende Wagner in a black wig, has no English dialogue. Rio Conchos was filmed in Moab, Utah, though the Conchos River and most of the action of the film takes place in Mexico.
Jerry Goldsmith's complete soundtrack was given a limited release on CD in January 2000 by Film Score Monthly that featured a tie-in title song by Johnny Desmond.
On June 21, 2011, Shout! Factory released the film on DVD as part of a double feature with Take a Hard Ride (1975).
An ex-Confederate Army officer (Richard Boone) named Jim Lassiter, who has been out for revenge against Apache Indians who massacred his family, recovers a stolen U.S. Army repeating rifle from some Apaches he has killed; as the Apache have proven formidable with lesser weaponry, there is cause for concern should they become equipped with such superior firepower.
