Lakes and Rivers Northwest of Valdes Peninsula, Argentina

Argentina- June 26th, 2010

The Valdes Peninsula (Spanish: Península Valdés) protudes off the northeastern coastline of Chubut Province, in Argentine Patagonia. A few salt lakes can be observed as lighter patches on the otherwise tan and mostly barren land of the peninsula.

Moving to the northwest, a few lakes and rivers are visible in the upper left corner. The rivers are the Neuquén (above) and the Limay (below). The lakes, actually artificial reservoirs, are situated along these rivers.  The two clustered together to the west are part of the Cerros Colorados Complex, the reservoir to their south was created by the El Chocón Dam, and the lake furthest east is called Pellegrini Lake.

Provinces of Argentine Patagonia

This image of Argentina includes the provinces of Neuquén (upper left), Río Negro (upper right) and Chubut (lower half). Neuquén is located at the northern end of Patagonia. The province’s southeastern limits are set by the Limay River, facing the Río Negro Province.

There are two main distinctive landscapes; the mountainous fertile valleys with forest on the West, and the arid plateau with fertile land only near the basins of the rivers on the East, mainly the Limay River and Neuquén River.

Río Negro is also located at the northern edge of Patagonia. The main water source at the arid plains that cover most of the province is the Río Negro River, in whose valley most of the settlements and farms are located. The over 600 km of the Rio Negro’s valley are divided in Alto Valle (West), Valle Medio (center) and Valle Inferior (East).

Finally, Chubut is situated in the southern part of Argentina between the 42nd parallel south (forming the border with the Río Negro Province) and the 46th parallel south. The Andes range, partially visible in the lower left corner, separates the province from Chile.

Artificial Reservoirs in Neuquén Province, Argentina

Several artificial reservoirs created by dams on the Limay River lie across this image of Argentina’s Neuquén Province: (from lower left to upper right) the Piedra del Águila Reservoir, the Ezequiel Ramos Mejía Reservoir and the Los Barreales Reservoir.

The Piedra del Águila Dam, is the second of five dams on the Limay River in northwestern Argentine Patagonia (the Comahue region). It is situated at 590 m above mean sea level, downstream from the confluence of the Limay and the Collón Curá River.

The dam, inaugurated in 1993, is used for the generation of hydroelectricity and the regulation of the flow of the river. Its reservoir has an area of 305 km², a mean depth of 41.3 m (maximum 120 m), and a volume of 1.26×1010 m³.

Moving to the northeast, the El Chocón Dam is the fourth of five dams on the Limay River, at 381 m above mean sea level. While the formal name of the project is Embalse Ezequiel Ramos Mexía, in common use it ended up acquiring the name of the settlement that served as the construction’s base of operations, Villa El Chocón.

El Chocón is part of a larger engineering scheme that also includes the Cerros Colorados Complex, on the Neuquén River. Los Barreales Reservoir is part of that complex, situated in a natural depression in Patagonia that was converted into a lake upon receiving the diverted waters of the Neuquén River.

Chile, from the Antofagasta Region to the Los Lagos Region

The Andes Mountains run vertically through the center of this image, separating Chile (west) from Argentina (east). Upon opening the full image, much of the coast of Chile is visible, stretching from the Antofagasta Region in the north to the Los Lagos Region in the south.

The Antofagasta Region has a mostly desert climate, part of the Atacama Desert, with variations in the amount of annual rainfall from the coast to the highland desert. This varies greatly from the Los Lagos Region, which generally has a natural vegatation of Valdivian temperate rain forest. The coastal part, except for south of Chiloé Island, has a temperate climate with cold winter rain. To the south, the climate is characterized by constant rain and not having dry seasons.

Across the Andes in Argentina, in the lower right corner, is  the Ezequiel Ramos Mexía Reservoir, created by the El Chocón Dam on the Limay River in northwestern Argentine Patagonia. The dam is used to regulate the flow of the Limay River, for irrigation, and for the generation of hydroelectricity.

Light Summer Snowfall Over the Andes, Chile and Argentina

Chile - December 20th, 2009

The Andes Mountains, running along the border of Chile (west) and Argentina (east), appear covered in snow only near the highest peaks, due to the warmer temperatures of the southern hemisphere summer.

In Chile, several rivers spill sediments off the coast and into the Pacific Ocean. In Argentina, the two most prominent rivers  visible are linked to artificial lakes. These rivers are the Neuquén (above) and the Limay (below).

After being dammed for the generation of hydroelectric power, their respective reservoirs were created. The one furthest east is called Pellegrini Lake. The two clustered together to the west are part of the Cerros Colorados Complex, and the final one to the south was created by the El Chocón Dam.
