The Álvaro Obregón Dam (also known as theOviáchic Dam) is an embankment dam on the Yaqui River north of Ciudad Obregón, in Sonora, Mexico. The purpose of the dam is water supply for irrigation, flood control and hydroelectric power production. The dam supports a power station with two generators and a 19 MW installed capacity. [1]

Embankment dam large artificial dam

An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil, sand, clay, or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes such a dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance.

Yaqui River river in Mexico

The Yaqui River is a river in the state of Sonora in northwestern Mexico. It was formerly known as the Rio del Norte. Being the largest river system in the state of Sonora, the Yaqui river is used for irrigation, especially in the Valle del Yaqui.

Ciudad Obregón City in Sonora, Mexico

Background

Because of drought, the Álvaro Obregón Dam and others on the Sonora and Mayo Rivers were constructed in the 1940s and 1950s. Construction on the Álvaro Obregón Dam began in 1947 and was complete in 1952. The dam's power station was not operational until August 1957. [2] The dam is 57 m (187 ft) above the riverbed and 1,457 m (4,780 ft) long. [3] The dam has an additional saddle dam 2 km (1 mi) to its northwest and along with a system of canals, it helps irrigate 83% of a 232,999 ha (900 sq mi) area. [4] Because of drought in the 1990s and 2000s, 2004 was the first year that water from the dam's reservoir was not authorized for irrigation. [5]
