Spain and Portugal - April 15th, 2011

The Tagus River appears as a dark line flowing through a tan valley on the left side of this image of Portugal. The river reaches its large estuary near Lisbon, the country’s capital. Sediments cause the northern part of the estuary to differ in color from the southern part.

Two other large bodies of water can also be observed. One is the estuary of the Sado River by the city of Setúbal, southeast of the Tagus Estuary. The second is the Alqueva Reservoir, an artificial lake on the Guadiana River by the Spain-Portugal border.
