Brazil - April 28th, 2012

Two large, artificial reservoirs can be observed along the São Francisco River, in northeastern Brazil. The river marks the border between the states of Bahia (below) and Pernambuco (above). At 3,160 kilometres long, it is the longest river located entirely within Brazil.

The lake to the left is known as the Sobradinho Reservoir. It measures approximately 320 km (200 mi) long, 4,214 km2 (1,627 sq mi) in surface area, and has a storage capacity of 34.1 km3 (8.2 cu mi) at its nominal elevation of 392.5 m (1,287.7 ft), making it the 12th-largest reservoir (artificial lake) in the world. Golden sediments color the lower half of the lake.
