Lake Valencia, Venezuela

Lago de Valencia (Lake Valencia) is located in north-central Venezuela and is the largest freshwater lake in the country. The lake was formed approximately 2-3 million years ago due to faulting and subsequent damming of the Valencia River. The lake has been completely dry during several discrete periods of its geologic history. Since 1976 Lake Valencia water levels have risen due to diversion of water from neighboring watersheds—it currently acts as a reservoir for the surrounding urban centers (such as Maracay).

Lake Fucine, Italy

The light tan oval in this image is the floor of a lake in central Italy that has been drained by a tunnel dug through the surrounding hills. Numerous rectangular fields occupy the former lake bottom—now one of the most fertile regions of Italy. The area is still referred to as “Fucine Lake,” even though the lake has been dry for nearly 150 years.

Algae in Great Salt Lake

Algae in Great Salt Lake

The Great Salt Lake of northern Utah is a remnant of glacial Lake Bonneville that extended over much of present-day western Utah and into the neighboring states of Nevada and Idaho approximately 32,000 to 14,000 years ago. The north arm of the lake, displayed in this astronaut photograph from April 30, 2007, typically has twice the salinity of the rest of the lake due to impoundment of water by a railroad causeway that crosses the lake from east to west. The causeway restricts water flow, and the separation has led to a striking division in the types of algae and bacteria found in the north and south arms of the lake.
