The Sao Simao reservoir, near the confluence of the Rio Paranaiba and Rio Verde in Brazil, is featured in this image photographed by an Expedition 16 crewmember on the International Space Station (ISS). The Sao Simao reservoir is located on the border between the states of Goias and Minas Gerais. Though the town of Sao Simao was founded around 1935, major growth occurred when the hydroelectric power plant and dam were built - forming the reservoir - in 1975. The reservoir is part of a major navigation link that allows transport of goods and commerce between central Brazil, the Prata River and the South Atlantic. The image also highlights agricultural fields of various kinds and in different stages of cultivation. The major commodities include corn, soybeans, sesame seeds, sugarcane, beans, manioc, coffee and meat production.
