Mexico - April 8th, 2011

The Sea of Cortez, or Gulf of California, stretches between the Baja California Peninsula and the Mexican mainland.

Numerous islands can be seen in the sea, particularly along the eastern coast of the peninsula. The largest of these, Isla Ángel de la Guarda (also called Archangel Island, west) and Tiburón Island (east), can be observed in the upper left quadrant.

Areas of agriculture appear as green areas along the eastern shores of the sea (the western coast of mainland Mexico). Individual fields can be discerned in the full image.

Visible by one of these agricultural areas is Ciudad Obregón, the second largest city in the state of Sonora. It appears as a circular grey area, with the Álvaro Obregón Reservoir to the north.

A series of bays can be seen to the southeast of the agricultural zone in Sonora. These bays are by the coastal plain of the state of Sinaloa, a narrow strip of land that stretches along the length of the state and lies between the ocean and the foothills of the Sierra Madre Occidental Range.

The brown contours of the Sierra Madre Occidental descend into green hills and then tan coastal plans in this image of Mexico along the Gulf of California. Parts of the coastline, particularly in the state of Sinaloa (right), are characterized by many long, narrow sandbars and small islands.

Lake Ouiachic, also referred to as the Álvaro Obregón Reservoir, appears as a dark blue curved form in the upper left quadrant, north of Ciudad Obregón. This artificial lake is found in the foothills of the Sierra Madre Occidental, and fed and drained by the Yaqui River.

A series of other artificial lakes are visible on the right side of the image. Lake Luis Donaldo Colosio appears golden in color and has a winding shape. Below it is the larger, green Miguel Hidalgo Reservoir on the Fuerte River. Further south, the smaller Josefa Ortiz de Dominguez Reservoir on the Alamos River appears dark blue.

The large, bright white and grey checked area in this orthorectified image is a mostly agricultural zone in the Mexican state of Sonora. The intensely irrigated, expansive area of fields is bordered by the Gulf of California (or Sea of Cortez) below and the city of Ciudad Obregón above.

Ciudad Obregón (locally known simply as Obregón) is the second largest city in the northern Mexican state of Sonora and is situated 525 km (326 mi) south of the state’s border with the U.S. state of Arizona. It is also the municipal seat of Cajeme municipality, located in the Yaqui Valley.

Sun glint makes the Yaqui River, in the state of Sonora in northwestern Mexico, appear bright white. As it is the largest river system in the state of Sonora, the Yaqui River (Río Yaqui in Spanish) is used for irrigation.

The Yaqui River originates in the Sierra Madre Occidental and flows south and southwest to empty into the Gulf of California, part of which is also highlighted white from sun glint, near the port of Guaymas.

Its course is interrupted by several reservoirs, which provide water resources for the intensively irrigated region of Ciudad Obregón. Here, Lake Ouiachic (below) and the Plutarco Elías Calles Reservoir (above) can be seen along the river.

Lake Ouiachic (also referred to as the Álvaro Obregón Reservoir or El Oviáchic) is located in the foothills of the Sierra Madre Occidental, and fed and drained by the Yaqui River.

The dam was completed in 1952 with the purpose to regulate water flow of the Yaqui River, prevent floods, and generate electricity.

The Plutarco Elías Calles Reservoir was formed by the Plutarco Elías Calles Dam, also known as El Novillo. The dam was built for irrigation and generating electricity, with a maximum capacity of 135,000 kw.
