Brazil - May 6th, 2012

Visible near the bottom edge of this image is the reservoir creatd by the Serra da Mesa Dam, an embankment dam on the Tocantins River near Minaçu, in Goiás, Brazil. The dam creates the largest reservoir by volume in Brazil, with a capacity of 54,400,000,000 m3 (1.92×1012 cu ft) and surface area of 1,784 km2 (689 sq mi).

The border between the states of Goiás and Mato Grosso is marked by the dark brown area west of the reservoir. In Mato Grosso, the terrain appears mostly mixed between agricultural lands, some of which were deforested, and forests along rivers such as the Ronuro River, visible near the left edge carrying tan sediments.

The Serra da Mesa Dam (center), once known as Sao Felix, is an embankment dam on the Tocantins River near Minaçu in Goiás, Brazil. The dam serves an associated hydroelectric power plant with a 1,275 MW installed capacity and creates the largest reservoir by volume in Brazil.

The Serra da Mesa Dam is a 1,500 m (4,900 ft) long and 154 m (505 ft) tall earth-fill embankment dam with a clay core and in total contains 12,057,558 m3 (425,808,600 cu ft) of material. The reservoir created by the dam has a capacity of 54,400,000,000 m3 (1.92×1012 cu ft) and surface area of 1,784 km2 (689 sq mi). Of the reservoir’s volume, 43,250,000,000 m3 (1.527×1012 cu ft) is active (live or “useful”) storage.

The dam supports a spillway with five floodgates that are 15 m (49 ft) wide and 20.4 m (67 ft) high each. In total, the spillway has a 15,000 m3/s (530,000 cu ft/s) discharge capacity.

Lying between a plateau to the east (tan in color) and the Araguaia River to the west (in the midst of a green and brown wetlands area) is the reservoir of the Serra da Mesa Dam.

An embankment dam on the Tocantins River near Minaçu in Goiás, Brazil, the Serra da Mesa creates the largest reservoir by volume in Brazil, with a capacity of 54,400,000,000 m3 (1.92×1012 cu ft) and surface area of 1,784 km2 (689 sq mi).

Brazil - August 5th, 2010

Several fires in the Brazilian state of Mato Grosso release whitish grey plumes of smoke in a westwardly direction, creating a haze over the green landscape.

The fires are situated west of the Araguaia River, which provides the border between Mato Grosso and the state of Tocantins, to the east. Further east lies the Tocantins River, along which several lakes can be observed.

Brazil - April 15th, 2010

The Tocantins River flows vertically up along the left side of this image of Brazil. It is the central fluvial artery of the country, running from south to north for about 2,640 km. Much of the landscape near the river appears quite marshy.

Upon opening the full image, a fire can be seen towards the center left, just east of the Tocantins River. The plume of smoke from the fire is bright white and blowing due west.

Moving over to the right side of the image, a lengthy strip of land mostly used for agriculture can be observed. In the full image, many individual fields can be seen, with various shades of brown.
